+/**
+ * A list of screen keybinding information.
+ *
+ * Each action which can have a keystroke bound to it is listed below.
+ * To use this file, define keybind() to be a seven-argument macro (you can
+ * throw any of the arguments you please away), include this file,
+ * and then undefine the macro again.
+ *
+ * (If you aren't familiar with this technique, sometimes called "x-macros",
+ * see DDJ of May 2001: <http://www.ddj.com/cpp/184401387>.)
+ *
+ * This makes it possible to keep all information about all the keybindings
+ * in the same place.  The only exception is the code to run when an action
+ * is actually invoked; while we *could* have put that in this file, it would
+ * have made debugging ridiculously difficult.  Instead, each action should
+ * have a corresponding static function named handle_<name>() in
+ * keybindings.c.
+ *
+ * The arguments to keybind() are:
+ *   1) the name of the binding; a bareword identifier
+ *              (it's fine if it happens to clash with a C reserved word)
+ *   2) the name of the function which implements it.
+ *              Clearly we could have guessed this from the binding very often,
+ *              but we choose to write it in full for the benefit of grep.
+ *   3) an integer parameter to pass to the handler
+ *   4) a set of boolean flags, ORed together:
+ *       BINDING_PER_WINDOW  - this is a window-based binding.
+ *                             It is only valid if there is a
+ *                             current window, and will operate in
+ *                             some way on that window.
+ *       BINDING_REVERSES    - the binding can reverse if you hold down Shift
+ *       BINDING_IS_REVERSED - the same, but the senses are reversed from the
+ *                             handler's point of view (let me know if I should
+ *                             explain this better)
+ *      or 0 if no flag applies.
+ *
+ *   5) a string representing the default binding.
+ *          If this is NULL, the action is unbound by default.
+ *          Please use NULL and not "disabled".
+ *   6) a short description.
+ *          It must be marked translatable (i.e. inside "_(...)").
+ *
+ * Don't try to do XML entity escaping anywhere in the strings.

Author	SHA1	Message	Date
Carlos Garnacho	bdfb8609a3	window: Update drag hotspot as new touches approach Any number of touches >= 3 starts a drag operation, but the window jumped around as new touches joined. So recalculate the touch drag area/hotspot and tiling mode as expected as soon as touches enter/leave the drag op.	2011-10-31 01:09:36 +01:00
Carlos Garnacho	141a353a52	window: Implement tiling/maximizing through touch events If during a multitouch drag, the area height is 1.5x the original size, the window is tiled to the closest side the hotspot is on (left/right). If both with/height are 1.5x the original, the window is maximized.	2011-10-30 18:22:19 +01:00
Carlos Garnacho	15186016c2	window: Implement window moving through touch events Window moving is triggered by 3-4 simultaneous touch events on the window, the hotspot being in the center of the touch area bounding rect.	2011-10-30 18:22:19 +01:00
Carlos Garnacho	bd77a67ea4	devices-xi2: Enable touch events	2011-10-30 18:22:19 +01:00
Carlos Garnacho	2a9a499841	core: Handle TouchUpdate with TouchPendingEnd as TouchEnd The touch sequence is possibly unhandled, but we need a call to meta_window_end_touch() so such touch sequences are notified to the server, this would trigger the real TouchEnd event as the touch is rejected, but should be a no-op the second time	2011-10-30 18:22:18 +01:00
Carlos Garnacho	50aa509ee1	device-map: Get slave devices in the XI2 implementation Slave devices are at least needed for touch devices.	2011-10-30 18:22:18 +01:00
Carlos Garnacho	0eefb6b306	device-map: Implement passive touch grabs in XI2 backend	2011-10-30 18:22:18 +01:00
Carlos Garnacho	d115c90ed1	device-map: Add grab/ungrab_touch() methods These functions deal with passive touch grabs, where available	2011-10-30 18:22:18 +01:00
Carlos Garnacho	83096642f0	core: Add meta_input_event_get_source_device() This function would return the slave device behind and event, this is mostly needed for touch passive grabs, as XIAllowTouchEvents() at the moment requires a slave device, this has changed in the latest drafts of the multitouch protocol.	2011-10-30 18:22:18 +01:00
Carlos Garnacho	a65c4e993e	input-events: Add meta_input_event_get_touch_id() This function returns the touch ID generating an input event, if any.	2011-10-30 18:22:18 +01:00
Carlos Garnacho	e73a566eeb	input-events: Add meta_input_event_ignored() This function tells whether an input event should be ignored, the only current reason being the duplication of touch events and their emulated XI2 pointer event counterparts.	2011-10-30 18:22:18 +01:00
Carlos Garnacho	46ef055da5	input-events: Handle touch events TouchBegin/End/Update are now handled similarly to ButtonPress/Release/MotionNotify.	2011-10-30 18:22:18 +01:00
Carlos Garnacho	45450c2fa3	device-map: Initialize XInput 2.1 This is needed in order to use the Multitouch API.	2011-10-30 18:22:18 +01:00
Carlos Garnacho	afa4c643a8	configure: Look for Multitouch API in XInput2	2011-10-30 18:22:18 +01:00
Carlos Garnacho	5d1c302b18	frame: disallow frame operations if the popup is open If some device has a popped up menu, meta_frame_get_flags() returns 0 to indicate other devices cannot trigger any actions on the frame.	2011-10-30 18:22:17 +01:00
Carlos Garnacho	53b289ce25	ui: Add a MetaDevice arg to meta_window_menu_popup() This will be the device popping up the menu, gtk_menu_popup() uses the current GTK+ event device, and that might not even be filled up with mutter event bypassing.	2011-10-30 18:22:17 +01:00
Carlos Garnacho	776628fde2	window: Make MetaWindow keep a pointer to the popup menu Multiple windows may now have different popup menus, responding only to the device pair that popped it up.	2011-10-30 18:22:17 +01:00
Carlos Garnacho	b9f5185c90	ui: enable multidevice on frame windows This is so different pointers may have different cursors on them.	2011-10-30 18:22:17 +01:00
Carlos Garnacho	7555b092eb	frames: Use the triggering device when updating controls	2011-10-30 18:22:17 +01:00
Carlos Garnacho	f46ef5f6e0	frames: Get coordinates from event Don't spare a synchronous X call, instead translate properly the XEvent coordinates in ui.c and use the event coordinates in MetaFrames	2011-10-30 18:22:17 +01:00
Carlos Garnacho	0e182c7c3d	meta: Add device.h This is real proof noone tried the branch yet	2011-10-30 18:22:17 +01:00
Carlos Garnacho	84b9d5c9f9	display: Make focus info persistent It must not be freed (at least meanwhile the device pair exists), so ensure it's kept around, and we don't create info for a same keyboard twice.	2011-10-30 18:22:17 +01:00
Carlos Garnacho	8e3b9be79c	window: make guess_grab_pointer() more reliable Now either the current focus keyboard or the client pointer (i.e. the pointer paired to the last keyboard that had the window focus) are used to guess the pointer that should be grabbed.	2011-10-30 18:22:17 +01:00
Carlos Garnacho	74520ab20b	window: set the corresponding client pointer on focused windows. The client window determines the device pair that is used for core protocol calls such as XQueryPointer(), so different clients using the core protocol can be focused by different devices simultaneously.	2011-10-30 18:22:17 +01:00

Carlos Garnacho	40ec37eed0	core: enable XInput2 by default This is nothing but the beginning, things work with a single pointer/keyboard pair, but will be largely broken with multiple devices interacting simultaneously, so we first need a policy to establish a sensible behavior for extra pointer/keyboard pairs. the MUTTER_USE_CORE_DEVICES envvar has been added to force use of Xlib core events for devices in order to check for regressions.	2011-10-30 18:22:16 +01:00

Carlos Garnacho	dc5b813608	core: Make keyboard focus handling happen per-keyboard MetaFocusInfo is a struct holding all necessary info, code has been updated to use the per-keyboard focus info instead of the old fields.	2011-10-30 18:20:29 +01:00

Carlos Garnacho	7c86cb85ba	core: Keep track of per pointer/keyboard grabs There is now a MetaGrabInfo struct, holding all information about an ongoing grab, there were unfortunately no means of making this commit smaller, as things are too intertwined to separate it, On places where it was most obvious, the correct device has been used (in reaction to events, for example), in other parts, the private API has been extended to include the MetaDevice (or device ID for core.h functions), in other places, the virtual core pointer/keyboard are used out of cluelessness.	2011-10-30 18:19:51 +01:00
Carlos Garnacho	ab58d87142	ui: Use input-events.h to translate XEvents to GdkEvents This is the only use in the UI part of core functions not exported via core.h, but this is sort of a hack within a hack, and still better than doing the XInput2 vs core dance again.	2011-10-30 18:19:51 +01:00
Carlos Garnacho	e62076f055	devices: Make MetaDevice/MetaDeviceMap partly public MetaDevice is quite limited outside of the core, mostly useful to represent a device, and get the paired one.	2011-10-30 18:18:50 +01:00
