to a 'host' compositor. Sommelier includes a set of features that +allows it to run inside a tight jail or virtual machine. + +Sommelier can run as service or as a wrapper around the execution of a +program. As a service, it spawns new processes as needed to service clients. +The parent process is called the master sommelier. + +## Sommeliers + +### Master Sommelier + +The master sommelier instance will create a wayland socket in XDG_RUNTIME_DIR +and accept connections from regular wayland clients. Each connection will be +serviced by spawning a child sommelier process. + +### X11 Sommelier + +An X11 sommelier instance provides X11 forwarding. Xwayland is used to +accomplish this. A single X11 sommelier instance is typically shared across +all X11 clients as they often expect that they can use a shared X server for +communication. If the X11 sommelier instance crashes in this setup, it takes +all running X11 programs down with it. Multiple X11 sommelier instances +can be used for improved isolation or when per-client configuration is +needed, but it will be at the cost of losing the ability for programs to use +the X server for communication between each other. + +### Peer Sommelier + +Each Linux program that support the Wayland protocol can have its own sommelier. +This provides better use of multiple cores when servicing clients, and it +prevents errors in one client from causing other clients to crash. + +## Host Compositor Channel + +Sommelier needs a channel to the host compositor in order to serve Wayland +clients inside a container. If the container environment provides a socket +that can be used to establish a connection to the host compositor, then +pointing sommelier to this socket using the `--display=DISPLAY` flag is +sufficient. + +### VirtWL + +The VirtWL device can be used to establish a new connection when no socket +is available (typically when running inside a VM). If a VirtWL device has been +specified (e.g. `--virtwl-device=/dev/wl0`) then sommelier will use this +mechanism by default to establish new channels between the host compositor and +sommelier instances. Data is forwarded between the VirtWL device and the core +Wayland dispatch mechanism using non-blocking I/O multiplexing. + +## Shared Memory Drivers + +Shared memory allocated inside a container cannot always be shared with the +host compositor. Sommelier provides a shared memory driver option as a +solution for this. What's the most appropriate option depends on the host +compositor and device drivers available for allocating buffers. + +### Noop + +The `noop` shared memory driver simply forwards buffers to the host without +any special processing. This requires that the client inside the container is +using memory that can be shared with the host compositor. + +### VirtWL + +The `virtwl` driver creates a set of intermediate virtwl buffers for each +surface, and copies minimal damaged areas from the client’s standard shared +memory buffers into the virtwl buffers that can be shared with the host +compositor. + +### VirtWL-DMABuf + +The `virtwl-dmabuf` works the same way as the `virtwl` driver but allocates +buffers that can be shared with the host compositor using the linux_dmabuf +protocol. The benefits of using this driver over the basic `virtwl` driver +are: + +* Larger set of supported formats (E.g NV12). +* Host compositor can avoid expensive texture uploads. +* HW overlays can be used for presentation if support by the host compositor. + +### DMABuf + +The `dmabuf` driver is similar to the `virtwl-dmabuf` driver. It creates a set +of intermediate buffers for each surface and copies minimal damaged areas from +the client’s standard shared memory buffer into the DMABuf buffer. However, +the buffer is allocated using a DRM device and a prime FD is used to access +buffer memory inside the container. Intermediate buffers are shared with the +host compositor using the linux_dmabuf protocol. + +## Damage Tracking + +Shared memory drivers that use intermediate buffers require some form of +damage tracking in order to update intermediate buffers. + +### Surface Buffer Queue + +Each client surface in sommelier is associated with a buffer queue. Each +buffer in the buffer queue has a region (list of rectangles) that describes +the part of the buffer that is damaged compared to the last frame submitted +by the client. This provides high precision damage tracking across multiple +frames. Each new frame from the client adds damage to existing buffers. When +submitting a frame to the host compositor, the next available buffer is +dequeued and updated to not contain any damage. This is done by copying +contents from the current client buffer into the dequeued buffer. + +The client's buffer is released as soon as this copy operation described above +is complete and the client can then reuse the shared memory buffer for another +frame. + +Note: It is important to release the buffer immediately as clients don’t +expect it to be held by the compositor for long when using shared memory. + +### Back Pressure + +Sommelier doesn’t provide any back pressure for when the client is producing +contents faster than the host compositor can consume it. The size of the +buffer queue can as a result grow large. This is not a problem as Xwayland +and other clients handle back pressure themselves using Wayland frame +callbacks or similar mechanism. + +## Data Drivers + +Socket pairs created inside a container cannot always be shared with the +host compositor. Sommelier provides a data driver option as a solution +for this. + +### Noop + +The `noop` driver simply forwards socket pair FDs to the host without any +special processing. This requires that the client inside the container is +using socket pairs that can be shared with the host compositor. + +### VirtWL + +The `virtwl` driver creates a special pipe that can be shared with the host +compositor and forwards all data received over this pipe to the client FD. +Forwarding is done using non-blocking I/O multiplexing. + +## Flags and Settings + +Sommelier has two forms of configuration. Command line flags and environment +variables. Standard practice is to expose each option both as a command line +flag and as an environment variable. Command line flags will always override +the configuration provided by environment variables. This makes it easy to +run sommelier as a systemd service and allow the system-wide configuration +to be overridden using a local user provided systemd override file. + +## Density and Scaling + +A protocol aware proxy compositor between the client and the host compositor +makes it easier to support Linux programs that lack good HiDPI support. +It can also be used to adjust the scale of contents to support the dynamic +density changes that Chrome OS UI provide, and it gives the user an option +override any density decisions made by the host compositor. For example, +HiDPI aware programs can run at native display resolution, while some older +programs can use half of that resolution. + +### Contents Scaling + +Contents scaling can be applied to both native wayland clients and X11 +clients. It can be controlled using the `--scale=SCALE` flag or +`SOMMELIER_SCALE=SCALE` variable. Where `SCALE` is a display density +multiplier. For example, if the default density is 200 DPI, then using +`--scale=0.5` will result in contents produced for 100 DPI. + +### Scale Factor + +An optimal scale factor is calculated for Wayland clients based on contents +scale setting and the current host compositor scaling. This allows Wayland +clients to produce contents at an optimal resolution for all combinations of +scaling used by sommelier and the host compositor. + +### DPI + +An exact value for DPI is calculated by sommelier. However, many Linux +programs expect DPI to be one out of a well known set of values. Sommelier +solves this by adjusting DPI using a set of buckets. For example, given the +default set of buckets (72, 96, 160, 240), Sommelier will use 96 as DPI when +the exact value is 112, or 160 when exact value is 188. The DPI buckets that +sommelier should use can be specified with `--dpi=[DPI[,DPI...]]`. Where, +`--dpi=””` will result in sommelier exposing the exact DPI value to clients. + +### XCursor + +Sommelier will set `XCURSOR_SIZE` environment variable automatically based on +the contents scale and preferred host compositor scale factor. + +## Accelerators + +If the host compositor support dynamic handling of keyboard events, then +keyboard shortcuts are forwarded to the Linux program by default. A small set +of shortcuts are expected to be reserved by the host compositor. A list of +reserved shortcuts on Chrome OS can be found +[here](https://chromium.googlesource.com/chromium/src/+/master/ash/accelerators/accelerator_table.h#22). + +There’s unfortunately no reliable way to detect if a Linux program handled a +key event or not. This means that all non-reserved shortcuts that the user +want the host compositor to handle needs to be explicitly listed as an +accelerator. For example, on Chrome OS, the launcher can be brought up using +the "launcher" button during normal usage. The "launcher" button event is +forwarded to Linux programs by default so it won’t work when a Linux program +has keyboard focus unless this shortcut is explicitly listed as an accelerator. + +Sommelier provides the `--accelerator=ACCELERATORS` flag for this purpose. +`ACCELERATORS` is a comma separated list of accelerators that shouldn’t be +forwarded to the Linux program but instead handled by the host compositor. +Each accelerator can contain a list of modifiers (e.g. ``) and +must be followed by an XKB keysym. The `xev` utility can be used to determine +what the XKB keysym is for a specific key. Given the launcher button example +above (which happens to have XKB keysym `Super_L` on the Chromebook Pixel), +`--accelerators=Super_L` needs to be passed to sommelier for the this button to +bring up the application launcher when Linux programs have keyboard focus. + +Consistent with other flags, `SOMMELIER_ACCELERATORS` environment variable can +be used as an alternative to the command line flag. + +## Examples + +Start master sommelier and use wayland-1 as name of socket to listen on: + +``` +sommelier --master --socket=wayland-1 +``` + +Start sommelier that runs weston-terminal with density scale multiplier 1.5: + +``` +sommelier --scale=1.5 weston-terminal +``` + +Start sommelier that runs inkscape with density scale multiplier 0.75 and 120 +dots per inch (note that -X is specified as inkscape is an X11 client and +requires X11 forwarding): + +``` +sommelier -X --scale=0.75 --dpi=120 inkscape +``` + +Start sommelier that runs gedit with some accelerators reserved to the host +compositor instead of being sent to gedit: + +``` +sommelier --accelerators="Bracketright,Bracketleft" gedit +``` diff --git a/sommelier/build/args.gn b/sommelier/build/args.gn new file mode 100644 index 0000000..5fc774c --- /dev/null +++ b/sommelier/build/args.gn @@ -0,0 +1,8 @@ +# Set build arguments here.

The wl_buffer is not created immediately but returned via + the 'created' event if the dmabuf sharing succeeds. The sharing + may fail at runtime for reasons a client cannot predict, in + which case the 'failed' event is triggered. + + The 'format' argument is a DRM_FORMAT code, as defined by the + libdrm's drm_fourcc.h. The Linux kernel's DRM sub-system is the + authoritative source on how the format codes should work. + + The 'flags' is a bitfield of the flags defined in enum "flags". + 'y_invert' means the that the image needs to be y-flipped. + + Flag 'interlaced' means that the frame in the buffer is not + progressive as usual, but interlaced. An interlaced buffer as + supported here must always contain both top and bottom fields. + The top field always begins on the first pixel row. The temporal + ordering between the two fields is top field first, unless + 'bottom_first' is specified. It is undefined whether 'bottom_first' + is ignored if 'interlaced' is not set. + + This protocol does not convey any information about field rate, + duration, or timing, other than the relative ordering between the + two fields in one buffer. A compositor may have to estimate the + intended field rate from the incoming buffer rate. It is undefined + whether the time of receiving wl_surface.commit with a new buffer + attached, applying the wl_surface state, wl_surface.frame callback + trigger, presentation, or any other point in the compositor cycle + is used to measure the frame or field times. There is no support + for detecting missed or late frames/fields/buffers either, and + there is no support whatsoever for cooperating with interlaced + compositor output. + + The composited image quality resulting from the use of interlaced + buffers is explicitly undefined. A compositor may use elaborate + hardware features or software to deinterlace and create progressive + output frames from a sequence of interlaced input buffers, or it + may produce substandard image quality. However, compositors that + cannot guarantee reasonable image quality in all cases are recommended + to just reject all interlaced buffers. + + Any argument errors, including non-positive width or height, + mismatch between the number of planes and the format, bad + format, bad offset or stride, may be indicated by fatal protocol + errors: INCOMPLETE, INVALID_FORMAT, INVALID_DIMENSIONS, + OUT_OF_BOUNDS. + + Dmabuf import errors in the server that are not obvious client + bugs are returned via the 'failed' event as non-fatal. This + allows attempting dmabuf sharing and falling back in the client + if it fails. + + This request can be sent only once in the object's lifetime, after + which the only legal request is destroy. This object should be + destroyed after issuing a 'create' request. Attempting to use this + object after issuing 'create' raises ALREADY_USED protocol error. + + It is not mandatory to issue 'create'. If a client wants to + cancel the buffer creation, it can just destroy this object. + + + + + + + + + + This event indicates that the attempted buffer creation was + successful. It provides the new wl_buffer referencing the dmabuf(s). + + Upon receiving this event, the client should destroy the + zlinux_dmabuf_params object. + + + + + + + This event indicates that the attempted buffer creation has + failed. It usually means that one of the dmabuf constraints + has not been fulfilled. + + Upon receiving this event, the client should destroy the + zlinux_buffer_params object. + + + + + + This asks for immediate creation of a wl_buffer by importing the + added dmabufs. + + In case of import success, no event is sent from the server, and the + wl_buffer is ready to be used by the client. + + Upon import failure, either of the following may happen, as seen fit + by the implementation: + - the client is terminated with one of the following fatal protocol + errors: + - INCOMPLETE, INVALID_FORMAT, INVALID_DIMENSIONS, OUT_OF_BOUNDS, + in case of argument errors such as mismatch between the number + of planes and the format, bad format, non-positive width or + height, or bad offset or stride. + - INVALID_WL_BUFFER, in case the cause for failure is unknown or + plaform specific. + - the server creates an invalid wl_buffer, marks it as failed and + sends a 'failed' event to the client.

The contents of the source rectangle are scaled to the + destination size, and content outside the source rectangle is ignored. + This state is double-buffered, and is applied on the next + wl_surface.commit. + + The two parts of crop and scale state are independent: the source + rectangle, and the destination size.

The whole of the current wl_buffer is + used as the source, and the surface size is as defined in + wl_surface.attach. + + If the destination size is set, it causes the surface size to become + dst_width, dst_height. The source (rectangle) is scaled to exactly + this size. This overrides whatever the attached wl_buffer size is, + unless the wl_buffer is NULL. If the wl_buffer is NULL, the surface + has no content and therefore no size.

This results in cropping + without scaling. If src_width or src_height are not integers and + destination size is not set, the bad_size protocol error is raised when + the surface state is applied. + + The coordinate transformations from buffer pixel coordinates up to + the surface-local coordinates happen in the following order: + 1. buffer_transform (wl_surface.set_buffer_transform) + 2. buffer_scale (wl_surface.set_buffer_scale) + 3. crop and scale (wp_viewport.set*) + This means, that the source rectangle coordinates of crop and scale + are given in the coordinates after the buffer transform and scale, + i.e. in the coordinates that would be the surface-local coordinates + if the crop and scale was not applied. + + If src_x or src_y are negative, the bad_value protocol error is raised. + Otherwise, if the source rectangle is partially or completely outside of + the non-NULL wl_buffer, then the out_of_buffer protocol error is raised + when the surface state is applied.

A positioner object is used to position + surfaces relative to some parent surface. See the interface description + and xdg_surface.get_popup for details. + + + + + + + This creates an xdg_surface for the given surface. While xdg_surface + itself is not a role, the corresponding surface may only be assigned + a role extending xdg_surface, such as xdg_toplevel or xdg_popup. + + This creates an xdg_surface for the given surface. An xdg_surface is + used as basis to define a role to a given surface, such as xdg_toplevel + or xdg_popup. It also manages functionality shared between xdg_surface + based surface roles. + + See the documentation of xdg_surface for more details about what an + xdg_surface is and how it is used. + + + + + + + + A client must respond to a ping event with a pong request or + the client may be deemed unresponsive. See xdg_shell.ping. + + + + + + + The ping event asks the client if it's still alive. Pass the + serial specified in the event back to the compositor by sending + a "pong" request back with the specified serial. See xdg_shell.ping. + + Compositors can use this to determine if the client is still + alive. It's unspecified what will happen if the client doesn't + respond to the ping request, or in what timeframe. Clients should + try to respond in a reasonable amount of time. + + A compositor is free to ping in any way it wants, but a client must + always respond to any xdg_shell object it created. + + + + + + + + The xdg_positioner provides a collection of rules for the placement of a + child surface relative to a parent surface. Rules can be defined to ensure + the child surface remains within the visible area's borders, and to + specify how the child surface changes its position, such as sliding along + an axis, or flipping around a rectangle. These positioner-created rules are + constrained by the requirement that a child surface must intersect with or + be at least partially adjacent to its parent surface. + + See the various requests for details about possible rules. + + At the time of the request, the compositor makes a copy of the rules + specified by the xdg_positioner. Thus, after the request is complete the + xdg_positioner object can be destroyed or reused; further changes to the + object will have no effect on previous usages. + + For an xdg_positioner object to be considered complete, it must have a + non-zero size set by set_size, and a non-zero anchor rectangle set by + set_anchor_rect. Passing an incomplete xdg_positioner object when + positioning a surface raises an error. + + + + + + + + + Notify the compositor that the xdg_positioner will no longer be used. + + + + + + Set the size of the surface that is to be positioned with the positioner + object. The size is in surface-local coordinates and corresponds to the + window geometry. See xdg_surface.set_window_geometry. + + If a zero or negative size is set the invalid_input error is raised. + + + + + + + + Specify the anchor rectangle within the parent surface that the child + surface will be placed relative to. The rectangle is relative to the + window geometry as defined by xdg_surface.set_window_geometry of the + parent surface. The rectangle must be at least 1x1 large. + + When the xdg_positioner object is used to position a child surface, the + anchor rectangle may not extend outside the window geometry of the + positioned child's parent surface. + + If a zero or negative size is set the invalid_input error is raised. + + + + + + + + + + + + + + + + + + Defines a set of edges for the anchor rectangle. These are used to + derive an anchor point that the child surface will be positioned + relative to. If two orthogonal edges are specified (e.g. 'top' and + 'left'), then the anchor point will be the intersection of the edges + (e.g. the top left position of the rectangle); otherwise, the derived + anchor point will be centered on the specified edge, or in the center of + the anchor rectangle if no edge is specified. + + If two parallel anchor edges are specified (e.g. 'left' and 'right'), + the invalid_input error is raised. + + + + + + + + + + + + + + + Defines in what direction a surface should be positioned, relative to + the anchor point of the parent surface. If two orthogonal gravities are + specified (e.g. 'bottom' and 'right'), then the child surface will be + placed in the specified direction; otherwise, the child surface will be + centered over the anchor point on any axis that had no gravity + specified. + + If two parallel gravities are specified (e.g. 'left' and 'right'), the + invalid_input error is raised. + + + + + + + The constraint adjustment value define ways the compositor will adjust + the position of the surface, if the unadjusted position would result + in the surface being partly constrained. + + Whether a surface is considered 'constrained' is left to the compositor + to determine. For example, the surface may be partly outside the + compositor's defined 'work area', thus necessitating the child surface's + position be adjusted until it is entirely inside the work area. + + The adjustments can be combined, according to a defined precedence: 1) + Flip, 2) Slide, 3) Resize. + + + + Don't alter the surface position even if it is constrained on some + axis, for example partially outside the edge of a monitor. + + + + + Slide the surface along the x axis until it is no longer constrained. + + First try to slide towards the direction of the gravity on the x axis + until either the edge in the opposite direction of the gravity is + unconstrained or the edge in the direction of the gravity is + constrained. + + Then try to slide towards the opposite direction of the gravity on the + x axis until either the edge in the direction of the gravity is + unconstrained or the edge in the opposite direction of the gravity is + constrained. + + + + + Slide the surface along the y axis until it is no longer constrained. + + First try to slide towards the direction of the gravity on the y axis + until either the edge in the opposite direction of the gravity is + unconstrained or the edge in the direction of the gravity is + constrained. + + Then try to slide towards the opposite direction of the gravity on the + y axis until either the edge in the direction of the gravity is + unconstrained or the edge in the opposite direction of the gravity is + constrained. + + + + + Invert the anchor and gravity on the x axis if the surface is + constrained on the x axis. For example, if the left edge of the + surface is constrained, the gravity is 'left' and the anchor is + 'left', change the gravity to 'right' and the anchor to 'right'. + + If the adjusted position also ends up being constrained, the resulting + position of the flip_x adjustment will be the one before the + adjustment. + + + + + Invert the anchor and gravity on the y axis if the surface is + constrained on the y axis. For example, if the bottom edge of the + surface is constrained, the gravity is 'bottom' and the anchor is + 'bottom', change the gravity to 'top' and the anchor to 'top'. + + If the adjusted position also ends up being constrained, the resulting + position of the flip_y adjustment will be the one before the + adjustment. + + + + + Resize the surface horizontally so that it is completely + unconstrained. + + + + + Resize the surface vertically so that it is completely unconstrained. + + + + + + + Specify how the window should be positioned if the originally intended + position caused the surface to be constrained, meaning at least + partially outside positioning boundaries set by the compositor. The + adjustment is set by constructing a bitmask describing the adjustment to + be made when the surface is constrained on that axis. + + If no bit for one axis is set, the compositor will assume that the child + surface should not change its position on that axis when constrained. + + If more than one bit for one axis is set, the order of how adjustments + are applied is specified in the corresponding adjustment descriptions. + + The default adjustment is none. + + + + + + + Specify the surface position offset relative to the position of the + anchor on the anchor rectangle and the anchor on the surface. For + example if the anchor of the anchor rectangle is at (x, y), the surface + has the gravity bottom|right, and the offset is (ox, oy), the calculated + surface position will be (x + ox, y + oy). The offset position of the + surface is the one used for constraint testing. See + set_constraint_adjustment. + + An example use case is placing a popup menu on top of a user interface + element, while aligning the user interface element of the parent surface + with some user interface element placed somewhere in the popup surface. + + + + + + + + + An interface that may be implemented by a wl_surface, for + implementations that provide a desktop-style user interface. + + It provides a base set of functionality required to construct user + interface elements requiring management by the compositor, such as + toplevel windows, menus, etc. The types of functionality are split into + xdg_surface roles. + + Creating an xdg_surface does not set the role for a wl_surface. In order + to map an xdg_surface, the client must create a role-specific object + using, e.g., get_toplevel, get_popup. The wl_surface for any given + xdg_surface can have at most one role, and may not be assigned any role + not based on xdg_surface. + + A role must be assigned before any other requests are made to the + xdg_surface object. + + The client must call wl_surface.commit on the corresponding wl_surface + for the xdg_surface state to take effect. + + Creating an xdg_surface from a wl_surface which has a buffer attached or + committed is a client error, and any attempts by a client to attach or + manipulate a buffer prior to the first xdg_surface.configure call must + also be treated as errors. + + For a surface to be mapped by the compositor, the following conditions + must be met: (1) the client has assigned a xdg_surface based role to the + surface, (2) the client has set and committed the xdg_surface state and + the role dependent state to the surface and (3) the client has committed a + buffer to the surface. + + + + + + + + + + + Destroy the xdg_surface object. An xdg_surface must only be destroyed + after its role object has been destroyed. + + + + + + This creates an xdg_toplevel object for the given xdg_surface and gives + the associated wl_surface the xdg_toplevel role. + + See the documentation of xdg_toplevel for more details about what an + xdg_toplevel is and how it is used. + + + + + + + This creates an xdg_popup object for the given xdg_surface and gives the + associated wl_surface the xdg_popup role. + + See the documentation of xdg_popup for more details about what an + xdg_popup is and how it is used. + + + + + + + + + The window geometry of a surface is its "visible bounds" from the + user's perspective. Client-side decorations often have invisible + portions like drop-shadows which should be ignored for the + purposes of aligning, placing and constraining windows. + + The window geometry is double buffered, and will be applied at the + time wl_surface.commit of the corresponding wl_surface is called. + + Once the window geometry of the surface is set, it is not possible to + unset it, and it will remain the same until set_window_geometry is + called again, even if a new subsurface or buffer is attached. + + If never set, the value is the full bounds of the surface, + including any subsurfaces. This updates dynamically on every + commit. This unset is meant for extremely simple clients. + + The arguments are given in the surface-local coordinate space of + the wl_surface associated with this xdg_surface. + + The width and height must be greater than zero. Setting an invalid size + will raise an error. When applied, the effective window geometry will be + the set window geometry clamped to the bounding rectangle of the + combined geometry of the surface of the xdg_surface and the associated + subsurfaces. + + + + + + + + + + When a configure event is received, if a client commits the + surface in response to the configure event, then the client + must make an ack_configure request sometime before the commit + request, passing along the serial of the configure event. + + For instance, for toplevel surfaces the compositor might use this + information to move a surface to the top left only when the client has + drawn itself for the maximized or fullscreen state. + + If the client receives multiple configure events before it + can respond to one, it only has to ack the last configure event. + + A client is not required to commit immediately after sending + an ack_configure request - it may even ack_configure several times + before its next surface commit. + + A client may send multiple ack_configure requests before committing, but + only the last request sent before a commit indicates which configure + event the client really is responding to. + + + + + + + The configure event marks the end of a configure sequence. A configure + sequence is a set of one or more events configuring the state of the + xdg_surface, including the final xdg_surface.configure event. + + Where applicable, xdg_surface surface roles will during a configure + sequence extend this event as a latched state sent as events before the + xdg_surface.configure event. Such events should be considered to make up + a set of atomically applied configuration states, where the + xdg_surface.configure commits the accumulated state. + + Clients should arrange their surface for the new states, and then send + an ack_configure request with the serial sent in this configure event at + some point before committing the new surface. + + If the client receives multiple configure events before it can respond + to one, it is free to discard all but the last event it received. + + + + + + + + This interface defines an xdg_surface role which allows a surface to, + among other things, set window-like properties such as maximize, + fullscreen, and minimize, set application-specific metadata like title and + id, and well as trigger user interactive operations such as interactive + resize and move. + + + + + Unmap and destroy the window. The window will be effectively + hidden from the user's point of view, and all state like + maximization, fullscreen, and so on, will be lost. + + + + + + Set the "parent" of this surface. This window should be stacked + above a parent. The parent surface must be mapped as long as this + surface is mapped. + + Parent windows should be set on dialogs, toolboxes, or other + "auxiliary" surfaces, so that the parent is raised when the dialog + is raised. + + + + + + + Set a short title for the surface. + + This string may be used to identify the surface in a task bar, + window list, or other user interface elements provided by the + compositor. + + The string must be encoded in UTF-8. + + + + + + + Set an application identifier for the surface. + + The app ID identifies the general class of applications to which + the surface belongs. The compositor can use this to group multiple + surfaces together, or to determine how to launch a new application. + + For D-Bus activatable applications, the app ID is used as the D-Bus + service name. + + The compositor shell will try to group application surfaces together + by their app ID. As a best practice, it is suggested to select app + ID's that match the basename of the application's .desktop file. + For example, "org.freedesktop.FooViewer" where the .desktop file is + "org.freedesktop.FooViewer.desktop". + + See the desktop-entry specification [0] for more details on + application identifiers and how they relate to well-known D-Bus + names and .desktop files. + + [0] http://standards.freedesktop.org/desktop-entry-spec/ + + + + + + + Clients implementing client-side decorations might want to show + a context menu when right-clicking on the decorations, giving the + user a menu that they can use to maximize or minimize the window. + + This request asks the compositor to pop up such a window menu at + the given position, relative to the local surface coordinates of + the parent surface. There are no guarantees as to what menu items + the window menu contains. + + This request must be used in response to some sort of user action + like a button press, key press, or touch down event. + + + + + + + + + + Start an interactive, user-driven move of the surface. + + This request must be used in response to some sort of user action + like a button press, key press, or touch down event. The passed + serial is used to determine the type of interactive move (touch, + pointer, etc). + + The server may ignore move requests depending on the state of + the surface (e.g. fullscreen or maximized), or if the passed serial + is no longer valid. + + If triggered, the surface will lose the focus of the device + (wl_pointer, wl_touch, etc) used for the move. It is up to the + compositor to visually indicate that the move is taking place, such as + updating a pointer cursor, during the move. There is no guarantee + that the device focus will return when the move is completed. + + + + + + + + These values are used to indicate which edge of a surface + is being dragged in a resize operation. + + + + + + + + + + + + + + + Start a user-driven, interactive resize of the surface. + + This request must be used in response to some sort of user action + like a button press, key press, or touch down event. The passed + serial is used to determine the type of interactive resize (touch, + pointer, etc). + + The server may ignore resize requests depending on the state of + the surface (e.g. fullscreen or maximized). + + If triggered, the client will receive configure events with the + "resize" state enum value and the expected sizes. See the "resize" + enum value for more details about what is required. The client + must also acknowledge configure events using "ack_configure". After + the resize is completed, the client will receive another "configure" + event without the resize state. + + If triggered, the surface also will lose the focus of the device + (wl_pointer, wl_touch, etc) used for the resize. It is up to the + compositor to visually indicate that the resize is taking place, + such as updating a pointer cursor, during the resize. There is no + guarantee that the device focus will return when the resize is + completed. + + The edges parameter specifies how the surface should be resized, + and is one of the values of the resize_edge enum. The compositor + may use this information to update the surface position for + example when dragging the top left corner. The compositor may also + use this information to adapt its behavior, e.g. choose an + appropriate cursor image. + + + + + + + + + The different state values used on the surface. This is designed for + state values like maximized, fullscreen. It is paired with the + configure event to ensure that both the client and the compositor + setting the state can be synchronized. + + States set in this way are double-buffered. They will get applied on + the next commit. + + + + The surface is maximized. The window geometry specified in the configure + event must be obeyed by the client. + + + + + The surface is fullscreen. The window geometry specified in the configure + event must be obeyed by the client. + + + + + The surface is being resized. The window geometry specified in the + configure event is a maximum; the client cannot resize beyond it. + Clients that have aspect ratio or cell sizing configuration can use + a smaller size, however. + + + + + Client window decorations should be painted as if the window is + active. Do not assume this means that the window actually has + keyboard or pointer focus. + + + + + + + Set a maximum size for the window. + + The client can specify a maximum size so that the compositor does + not try to configure the window beyond this size. + + The width and height arguments are in window geometry coordinates. + See xdg_surface.set_window_geometry. + + Values set in this way are double-buffered. They will get applied + on the next commit. + + The compositor can use this information to allow or disallow + different states like maximize or fullscreen and draw accurate + animations. + + Similarly, a tiling window manager may use this information to + place and resize client windows in a more effective way. + + The client should not rely on the compositor to obey the maximum + size. The compositor may decide to ignore the values set by the + client and request a larger size. + + If never set, or a value of zero in the request, means that the + client has no expected maximum size in the given dimension. + As a result, a client wishing to reset the maximum size + to an unspecified state can use zero for width and height in the + request. + + Requesting a maximum size to be smaller than the minimum size of + a surface is illegal and will result in a protocol error. + + The width and height must be greater than or equal to zero. Using + strictly negative values for width and height will result in a + protocol error. + + + + + + + + Set a minimum size for the window. + + The client can specify a minimum size so that the compositor does + not try to configure the window below this size. + + The width and height arguments are in window geometry coordinates. + See xdg_surface.set_window_geometry. + + Values set in this way are double-buffered.

Using + strictly negative values for width and height will result in a + protocol error. + + + + + + + + Maximize the surface. + + After requesting that the surface should be maximized, the compositor + will respond by emitting a configure event with the "maximized" state + and the required window geometry. The client should then update its + content, drawing it in a maximized state, i.e. without shadow or other + decoration outside of the window geometry. The client must also + acknowledge the configure when committing the new content (see + ack_configure). + + It is up to the compositor to decide how and where to maximize the + surface, for example which output and what region of the screen should + be used. + + If the surface was already maximized, the compositor will still emit + a configure event with the "maximized" state. + + + + + + Unmaximize the surface. + + After requesting that the surface should be unmaximized, the compositor + will respond by emitting a configure event without the "maximized" + state. If available, the compositor will include the window geometry + dimensions the window had prior to being maximized in the configure + request. The client must then update its content, drawing it in a + regular state, i.e. potentially with shadow, etc. The client must also + acknowledge the configure when committing the new content (see + ack_configure). + + It is up to the compositor to position the surface after it was + unmaximized; usually the position the surface had before maximizing, if + applicable. + + If the surface was already not maximized, the compositor will still + emit a configure event without the "maximized" state. + + + + + + Make the surface fullscreen. + + You can specify an output that you would prefer to be fullscreen. + If this value is NULL, it's up to the compositor to choose which + display will be used to map this surface. + + If the surface doesn't cover the whole output, the compositor will + position the surface in the center of the output and compensate with + black borders filling the rest of the output. + + + + + + + + Request that the compositor minimize your surface. There is no + way to know if the surface is currently minimized, nor is there + any way to unset minimization on this surface. + + If you are looking to throttle redrawing when minimized, please + instead use the wl_surface.frame event for this, as this will + also work with live previews on windows in Alt-Tab, Expose or + similar compositor features. + + + + + + This configure event asks the client to resize its toplevel surface or + to change its state. The configured state should not be applied + immediately. See xdg_surface.configure for details. + + The width and height arguments specify a hint to the window + about how its surface should be resized in window geometry + coordinates. See set_window_geometry. + + If the width or height arguments are zero, it means the client + should decide its own window dimension. This may happen when the + compositor needs to configure the state of the surface but doesn't + have any information about any previous or expected dimension. + + The states listed in the event specify how the width/height + arguments should be interpreted, and possibly how it should be + drawn. + + Clients must send an ack_configure in response to this event. See + xdg_surface.configure and xdg_surface.ack_configure for details. + + + + + + + + + The close event is sent by the compositor when the user + wants the surface to be closed. This should be equivalent to + the user clicking the close button in client-side decorations, + if your application has any. + + This is only a request that the user intends to close the + window. The client may choose to ignore this request, or show + a dialog to ask the user to save their data, etc. + + + + + + + A popup surface is a short-lived, temporary surface. It can be used to + implement for example menus, popovers, tooltips and other similar user + interface concepts. + + A popup can be made to take an explicit grab. See xdg_popup.grab for + details. + + When the popup is dismissed, a popup_done event will be sent out, and at + the same time the surface will be unmapped. See the xdg_popup.popup_done + event for details. + + Explicitly destroying the xdg_popup object will also dismiss the popup and + unmap the surface. Clients that want to dismiss the popup when another + surface of their own is clicked should dismiss the popup using the destroy + request. + + The parent surface must have either the xdg_toplevel or xdg_popup surface + role. + + A newly created xdg_popup will be stacked on top of all previously created + xdg_popup surfaces associated with the same xdg_toplevel. + + The parent of an xdg_popup must be mapped (see the xdg_surface + description) before the xdg_popup itself. + + The x and y arguments passed when creating the popup object specify + where the top left of the popup should be placed, relative to the + local surface coordinates of the parent surface. See + xdg_surface.get_popup. An xdg_popup must intersect with or be at least + partially adjacent to its parent surface. + + The client must call wl_surface.commit on the corresponding wl_surface + for the xdg_popup state to take effect. + + + + + + + + + This destroys the popup. Explicitly destroying the xdg_popup + object will also dismiss the popup, and unmap the surface. + + If this xdg_popup is not the "topmost" popup, a protocol error + will be sent. + + + + + + This request makes the created popup take an explicit grab. An explicit + grab will be dismissed when the user dismisses the popup, or when the + client destroys the xdg_popup. This can be done by the user clicking + outside the surface, using the keyboard, or even locking the screen + through closing the lid or a timeout. + + If the compositor denies the grab, the popup will be immediately + dismissed. + + This request must be used in response to some sort of user action like a + button press, key press, or touch down event. The serial number of the + event should be passed as 'serial'. + + The parent of a grabbing popup must either be an xdg_toplevel surface or + another xdg_popup with an explicit grab. If the parent is another + xdg_popup it means that the popups are nested, with this popup now being + the topmost popup. + + Nested popups must be destroyed in the reverse order they were created + in, e.g. the only popup you are allowed to destroy at all times is the + topmost one. + + When compositors choose to dismiss a popup, they may dismiss every + nested grabbing popup as well. When a compositor dismisses popups, it + will follow the same dismissing order as required from the client. + + The parent of a grabbing popup must either be another xdg_popup with an + active explicit grab, or an xdg_popup or xdg_toplevel, if there are no + explicit grabs already taken. + + If the topmost grabbing popup is destroyed, the grab will be returned to + the parent of the popup, if that parent previously had an explicit grab. + + If the parent is a grabbing popup which has already been dismissed, this + popup will be immediately dismissed. If the parent is a popup that did + not take an explicit grab, an error will be raised. + + During a popup grab, the client owning the grab will receive pointer + and touch events for all their surfaces as normal (similar to an + "owner-events" grab in X11 parlance), while the top most grabbing popup + will always have keyboard focus. + + + + + + + + This event asks the popup surface to configure itself given the + configuration.
