In a variety of places we're using boxes as data-modeling displays,
and in doing so we often want to either remove the children or
explictly destroy them.
Now ideally Gjs would support callbacks, and this would make using
the for_each functions possible, but even then these functions
are more efficient and shorter to type, at least.
https://bugzilla.gnome.org/show_bug.cgi?id=600734
If the space we're allocated is too small for our border + padding
constraints, don't give negative allocations to callers. Squash
to zero.
It isn't really useful for callers to get negative content sizes,
and certainly breaks most allocation code.
https://bugzilla.gnome.org/show_bug.cgi?id=600734
StTheme CSS supports different border widths for different sides. Implement
it for StWidget by drawing the border internally. However, we don't support
a nonzero corner-radius with nonuniform borders.
https://bugzilla.gnome.org/show_bug.cgi?id=599442
Previously shell_app_remove_window assumed that it was being
passed a window in its list; rather than having callers check
whether a window is interesting and only if so removing it
from the app, just ignore removal of windows we aren't interested
in, like how we ignore addition of windows we already have.
https://bugzilla.gnome.org/show_bug.cgi?id=598502
The behavior in respect to borders matches CSS - the properties set the size of
the content exclusive of the borders (CSS3 box-sizing property - not implemented
here - changes this).
min-width/min-height correspond very closely to the CSS meanings.
width/height are a little different from the CSS meanings - the CSS meaning is
"exactly this size unless overridden by min/max-width/height" - but within the
realm of our layout algorithm, making them control natural size is pretty
close.
This way we can force elements to have a fixed natural or minimum size.
https://bugzilla.gnome.org/show_bug.cgi?id=598651
For the purposes of determining which application is focused, don't
skip "uninteresting" windows. The old get_focused_window code
was used for usage tracking, but here we want reliable application
association.
Also convert a .text= to .set_text that was missed with the last
patch.
https://bugzilla.gnome.org/show_bug.cgi?id=599206
The two parts were mapping windows to applications, and
recording application usage statistics. The latter part
(now called ShellAppUsage) is much more naturally built on top of
the former (now called ShellWindowTracker).
ShellWindowTracker retains the startup-notification handling.
ShellWindowTracker also gains a focus-app property, which is
what most things in the shell UI are interested in (instead of
window focus).
ShellAppSystem moves to exporting ShellApp from more of its
public API, rather than ShellAppInfo. ShellAppSystem also
ensures that ShellApp instances are unique by holding
a hash on the ids.
ShellApp's private API is split off into a shell-app-private.h,
so shell-app.h can be included in shell-app-system.h.
Favorites handling is removed from ShellAppSystem, now inside
appFavorites.js.
Port all of the JavaScript for these changes.
https://bugzilla.gnome.org/show_bug.cgi?id=598646
The window lists were not being resorted when user-time changed, and
the app list was mistakenly "penalizing" apps for having *any*
minimized windows, rather than for having *only* minimized windows.
https://bugzilla.gnome.org/show_bug.cgi?id=598389
Previously, we had ShellAppInfo, which contains fundamental
information about an application, and methods on ShellAppMonitor
to retrieve "live" information like the window list.
AppIcon ended up being used as the "App" class which was painful
for various reasons; among them that we need to handle window
list changes, and some consumers weren't ready for that.
Clean things up a bit by introducing a new ShellApp class in C,
which currently wraps a ShellAppInfo.
AppIcon then is more like the display actor for a ShellApp. Notably,
the ".windows" property moves out of it. The altTab code which
won't handle dynamic changes instead is changed to maintain a
cached version.
ShellAppMonitor gains some more methods related to ShellApp now.
In the future, we might consider changing ShellApp to be a GInterface,
which could be implemented by ShellDesktopFileApp, ShellWindowApp.
Then we could axe ShellAppInfo from the "public" API and it would
return to being an internal loss mitigation layer for GMenu.
https://bugzilla.gnome.org/show_bug.cgi?id=598227
ClutterGroup calls _destroy, but most of St was just calling _unparent.
This caused problems because the DESTROY signal was not emitted
for child elements after destroying a toplevel. Also, in a GC'd
binding it would cause unpredictable lifetime of children.
Some St widgets simply didn't have _dispose at all; implement it.
Note because of the usage of the background_image in StButton,
we can't cleanly destroy it inside the StWidget.
https://bugzilla.gnome.org/show_bug.cgi?id=597845
When we get a ClutterModifierType from Clutter, it might contain
bits not in the enumeration. See bug 59771 for a similar problem
with GdkModifierType.
Add a wrapper Shell.get_event_state() around clutter_event_get_state()
to mask these bits out and only return approved bits.
https://bugzilla.gnome.org/show_bug.cgi?id=597735
gdk_display_get_pointer() sometimes returns values for the mask that
aren't part of the GdkModifierType enumeration, which gjs doesn't like
(bug 597292). Work around that by adding a C wrapper that strips out
the extra flags.
https://bugzilla.gnome.org/show_bug.cgi?id=597559
Add StIMText, which is a drop-in replacement for ClutterIMText but
uses GtkIMContext instead of ClutterIMContext.
StIMText doesn't have preedit support (would need ClutterText
changes), so isn't going to be useful for complicated input methods,
but is good enough to get dead keys and similar working.

To work around a problem where libcroco < 0.6.2 can't handle
functions starting with 'r' or 'u', preconvert 'rgba' to 'RGBA'
when parsing stylesheets and then check for rgba()
case-insensitively.
(libcroco is uniformly case-sensitive, though the CSS spec requires
that ASCII should be handled case-insensitively.)
https://bugzilla.gnome.org/show_bug.cgi?id=597054
Before we hardcoded popdowns to only button 1 before. But we need
to actually pop down on the release of the activating button.
(Once the button is released, if the we don't pop-down the menu,
then subsequently we let the user use any button.)
https://bugzilla.gnome.org/show_bug.cgi?id=596371
round() is a C99 addition, so causes portability problems:
different C library versions require different #defines to
enable it. So simply avoid using it.
Property enumeration names should correspond exactly to the property names;
in particular the ACTIVE vs :checked disparity was confusing reading the
code.
http://bugzilla.moblin.org/show_bug.cgi?id=6504
Convert the StTable code from StStylable to StThemeNode. The
:row-spacing and :col-spacing GObject properties are converted
into spacing-rows and spacing-columns style properties.
A new interactive test is added for StTable.
https://bugzilla.gnome.org/show_bug.cgi?id=596811
Remove the StTable specific methods to add actors:
st_table_add_actor()
st_table_add_actor_with_properties()
Since they shadow the generic ClutterContainer add_actor() method,
and patch in our add() convenience function as we do for
StBoxLayout.
https://bugzilla.gnome.org/show_bug.cgi?id=596811
Remove the StBoxLayout:spacing GObject property, and instead make
BoxLayout look up the spacing from the CSS style. This makes it
consistent with padding and will allow the use of units. (The
removal of the GObject property entirely instead of making it an
override is consistent with how we handle color, font, padding, etc.)
https://bugzilla.gnome.org/show_bug.cgi?id=596803
Add clutter-text properties to allow getting access to the underlying
ClutterText actor. This corresponds to the get_clutter_text() methods.
The PROP_LABEL and PROP_ENTRY enum values are renamed to PROP_TEXT to
match the names of the properties that they correspond to, and the
properties of StEntry are reordered into alphabetical order.
Based on a patch from Colin Walters
https://bugzilla.gnome.org/show_bug.cgi?id=591245http://bugzilla.moblin.org/show_bug.cgi?id=6313
StBoxLayout: Make consistent that the area scrolled and clipped
to is the content area (excluding borders and padding.) Translate
back appropriately when chaining up so that the parent background
is drawn at the right place and picking on the box (if it's reactive)
picks at the right place on the screen.
clip-to-allocation is removed from StScrollView since it's just
not right - if the child has any non-moving elements, like headers or
borders, it will need to set a narrower clip. And even if the entire
child scrolls, we want to clip to an arrow that excludes the scrollbars.
https://bugzilla.gnome.org/show_bug.cgi?id=595997
When a StBoxLayout is allocated a size less than its natural size,
think "shrink" needs to be divided among the children that have
a smaller minimum size than natural size.
This is done by preferentially shrinking the children that are most
expanded from their minimum size and then increasing that set of
children until we've found enough total shrink.
A new method is used of allocating children at integral sizes - instead
of rounding the per-child extra amount to an integer (which causes
cumulative round-off errors), compute the position as we go along in
floats and round individually for each child widget.
Extend the box-layout test to include of a test of a box being set
to various widths, starting quite narrow.
http://bugzilla.moblin.org/show_bug.cgi?id=6311https://bugzilla.gnome.org/show_bug.cgi?id=595995
If the actor isn't in a stage, then setting up the adjustment
based on the actor's size (which we can't compute) and the
size of the default stage (which isn't relevant), doesn't make
sense. Just use arbitrary default values.
The adjustments will be updated to reasonable values when first
the box is first allocated.
It's not entirely clear to me why we ever want to compute the
adjustment settings this way; perhaps we should always use
default values.
http://bugzilla.moblin.org/show_bug.cgi?id=6307https://bugzilla.gnome.org/show_bug.cgi?id=595996
The CSS specification says that the background extends to the
edge of the border (settable in CSS3 with border-clip), make
BigRectangle match this by computing an "effective border color"
as 'border OVER background'.
(If we don't want this behavior - e.g., to be able to use the
transparent borders as margins, then alternatively transparent
border handling would have to be fixed in st-widget.c, since
prior to this transparent and translucent borders were handled
differently.)
https://bugzilla.gnome.org/show_bug.cgi?id=595993
The current CSS3 border-image is close to a superset of what we were
doing for -hippo-background-image. Woot! rename StThemeImage to
StBorderImage and change parsing to look for:
border-image: <url> <number>...
Rather than
-st-background-image: <url> <length>...
percentanges for the border sizes are not currently supported, neither
are the keywords for handling of the middle part. We always do 'stretch'
for now.
https://bugzilla.gnome.org/show_bug.cgi?id=595990
Use BigRectangle to draw the border and background if there's
a border width or border radius and no border image. (Only
uniform borders are supported for now with some deviations
from the CSS model noted in the comments.)
The background color and image parameters are removed from
StWidget's draw_background() method since they were not used
for StButton (the only current user) and the encapsulation
break that they presented caused some minor problems.
Add a test case for borders, and also use borders to style
the buttons in the 'inline-style' test case.
https://bugzilla.gnome.org/show_bug.cgi?id=595993
Rather than repeating the computation of borders in many different
widget subclasses, add helper functions:
st_theme_node_adjust_for_height()
st_theme_node_adjust_preferred_width()
st_theme_node_adjust_for_width()
st_theme_node_adjust_preferred_height()
st_theme_node_get_content_box()
That are used in get_preferred_width()/get_preferred_height() and
allocate() methods to consistently apply the necessary adjustments.
This allows removing the StPadding type.
Queueing a relayout when the borders/padding change is moved from
st_widget_real_style_changed() to the invoking code to allow access
to the old StThemeNode for comparison. (Should this be added as
a parameter to the signal?)
Borders are included in the geometry adjustments, but borders
are not yet drawn.
https://bugzilla.gnome.org/show_bug.cgi?id=595993
Add support for parsing and caching the border-radius property.
Different radii for the 4 corners are supported; elliptical corners
are not supported.
https://bugzilla.gnome.org/show_bug.cgi?id=595993
Add support for passing an inline-style string when creating a
StThemeNode.
Hook this up to a new 'style' property of StWidget.
Add a test case that demonstrates using this to update font sizes
on the fly.
https://bugzilla.gnome.org/show_bug.cgi?id=595991
ShellTheme replaces both StStyle and ccss_stylesheet_t.
The interface StStylable is replaced by usage of ShellThemeNode.
A concrete node class allows some significant optimizations of property
inheritance that would have been much more difficult to achieve with
the highly abstract pair of StStylable and ccss_node_t.
Some operations that were previously on StStylable (like the
::style-changed signal) are directly on NtkWidget.
Custom properties are no longer registered as param-specs; instead you
call directly into shell theme node to look up a length or color:
shell_theme_node_get_length (theme_node, "border-spacing", FALSE, &spacing);
The dependency on libccss is dropped, while preserving all existing
functionality and adding proper parsing and inheritance of font properties
and proper inheritance for the 'color' property.
Some more javascript tests for CSS functionality are added; workarounds for
a CSS bug where *.some-class was needed instead of .some-class are removed.

To each .c and .h file, add:
/* -*- mode: C; c-file-style: "gnu"; indent-tabs-mode: nil; -*- */
'gnu' is the default anyways for Emacs, but indent-tabs-mode is not,

Various changes are made in the import:
- Comprehensive reindentation

Add GObject Introspection annotations to methods where needed, in
particular adding (transfer none) to return values that don't transfer

Import the core MxWidget/MxBin and their dependencies; we use the

Fix panel, app switcher, and looking glass to limit themselves to the
primary monitor, and run dialog to limit itself to the monitor
containing the currently-focused window.
The overview is also limited to the primary monitor now (with the
other monitors being blacked out), although the workspaces within the
overview are shaped like the full "screen" (the bounding box of all
monitors). To be fixed later.

Before, if the texture cache received a request to load say
the themed icon for an application multiple times (as could happen
since we have multiple application displays), it would often create
a thread for each one and in fact, load the pixbuf multiple times.
Avoid this by keeping track of outstanding requests.
https://bugzilla.gnome.org/show_bug.cgi?id=596121
This fixes a regression where we weren't using the correct event
timestamps, because for both of these we were sending an XClientMessage
to ourself.
https://bugzilla.gnome.org/show_bug.cgi?id=596262
A previous patch fixed a leak when loading items which shouldn't
be cached, but we also had a leak if two requests for the same
item were outstanding. In that case we load the pixbuf twice,
but should discard subsequent loads when we notice we've already
cached it.

The menu is needed by the app switcher as well as the overview, so
make it slightly more generic and move the code to appIcon. Also add
support for drawing the menu either to the right of or below the icon.
https://bugzilla.gnome.org/show_bug.cgi?id=590563
When the user click+hold+release over the icon, the effect we want
is for the menu to stick around.
Also, allow the user to mouse over the actual windows and select
them directly. If the user mouses over a window, reflect that in
the menu.
https://bugzilla.gnome.org/show_bug.cgi?id=594699
Callers will generally expect _popup and _popdown to be a no-op if
the menu is already in that state; make it so.
Also change the 'popdown' signal to be 'cancelled'; this is
clearer and allows us to avoid having activate also call popdown.
https://bugzilla.gnome.org/show_bug.cgi?id=594699
We have compatibility code which detects from the window title what
an application is. However, the code didn't handle the case where
we discovered by title, but didn't have the expected .desktop file
installed.
When the user click+hold+release over the icon, the effect we want
is for the menu to stick around.
Also, allow the user to mouse over the actual windows and select
them directly. If the user mouses over a window, reflect that in
the menu.
If start_shell() threw an exception before, we'd overwrite it with
an exception in the finally() clause. Handle this and just print a message
and let the exception propagate.
Before Clutter gained accessors for event information, we had
shell_global_ functions. Now that Clutter has them, use them and
delete the ShellGlobal code.

When we have multiple windows for an application, implement the following
behavior:
* On click + immediate release, go to the most recently used
* On click, hold for 0.6s, pop up a menu with windows, filtering
the window list to just those windows.
Mouse over on the window list highlights the moused-over window.
Implement this by splitting well item into InactiveWellItem
and RunningWellItem, sharing a base class BaseWellItem.
The application menu code wants to do a popup after a given timeout
while holding. We can implement that by adding a function to
manually break the grab held by the button box.
Freeze+thaw around the hover and pressed property notification on leave
since handlers may want to depend on the pressed state on a hover
transition.
The windows we considered for both the app monitor and the overview
workspaces were the same, but the code was duplicated once in C, once
in Javascript.
