1. Rename the thing
2. Turn it from a signal to a vfunc
3. Pass the GtkCssStyleChange to it
We don't export any public API about the GtkCssStyleChange yet, it's
just a boring opaque struct.
Most users were just forgetting to set the proper flags.
And flags aren't the right way to set this anyway, it was just
acceptable as a workaround during GTK3 to not break API.
The API encouraged wrong usage - most of the users were indeed wrong.
Use the correct version instead:
gtk_icon_theme_get_for_display (gtk_widget_get_display ())
The reason for this is simply that I want to get hash functions that
have their values close together, so they can fit in a smaller range
(the goal here is 12 bits). By using GQuark, we get consecutive numbers
starting with 1 (and applications have <1000 quarks usually), whereas
interned strings can be all over the place.
As a side effect we also save 64 bytes per declaration.
Previously, we wrapped all GtkCssShadowValues in a GtkCssShadowsValue,
even if it was just one shadow. This causes an unnecessary bloat in
css values.
Make each GtkCssShadowValue able to handle multiple shadows instead, and
use gtk_css_shadow_value* API everywhere.
The differenciation between a literal color value and an RGBA value
caused problems in various situations. Just treat the two the same but
don't allow access to the rgba value of a non-literal color value.
This gets rid of around 1.6k rgba values in the widget-factory.
This might happen if the CSS values of the decoration node are broken,
e.g. if people *accidentally* type large negative values for the
margins.
Fixes#2268
Decoration node for drawing is used only for client side decorated
windows, but corners from opaque region is subtracted also for
normal windows.
Rename function to better reflect what it does and do not subtract
corners if decoration node was not used for drawing.
The "iconified" state is mostly an X11-ism; every other platform calls
this state "minimized" because it may not involve turning a window into
an icon at all.
Unrealize the GSK renderer before destroying children.
This makes the renderer drop any texture caches that
it might have, so that we don't needlessly download
them when releasing the widget-side holder objects.
As a fortunate side effect, this fixes crashes on
exit with GtkGLArea-containing windows under Wayland.
When processing the list of icons for a window to add them to
_NET_WM_ICON gdk_x11_surface_set_icon_list only adds as many
icon sizes as will fit within X protocol limits.
It achieves this by keeping a running total of the number of
bytes taken up by icons already processed and bails as soon
as it goes over the limit.
The problem is, one 512x512 icon is already over the limit,
and so no icons will get added at all if the first icon in
list is 512x512.
Indeed, the code seems to assume the list is sorted from smallest
icon to biggest icon.
This commit changes the caller to sort the list.
