libkwineffects was introduced when kwin used to be an executable. It
provided an api to implement effects and shielded from the technical
quirks in kwin.
Over the time, kwin internals had been split and abstractions were
refactored so they can be consumed in scripts or plugins. Besides that,
new ways to implement extensions have been introduced, which use
kwin's internal abstractions.
On the other hand, effects continue using libkwineffects specific apis.
This has a few issues: qtquick effects use both apis and it bites us,
duplicating same apis.
The best solution so far is to merge libkwineffects with libkwin, and
replace libkwineffects abstractions with libkwin abstractions, e.g.
EffectScreen -> Output, etc. This change takes care of adjusting libs.
Obviously, the main disadvantage of doing so is that binary effects
have to be recompiled every time new libkwin is released. But it's
already the case with libkwineffects too.
onTextEdited only updates on user-invoked key presses, and not
programatic changes.
This is a better choice when we have a two-way bindings such as with
configuration files, but in this case we always want the UI to reflect
the current contents of the search box making onTextChanged the better
signal.
BUG: 475789
Doesn't seem to work quite right without sourcing the prefix, or while overriding the env variables entirely, for example it is unable to load any window decorations. By sourcing the prefix _and_ including the bin directory in the path, it seems to work as expected - or at least the window decorations load correctly now.
On X11, there's no per screen rendering. The primary screen is specified
as the painted screen. RenderViewport::renderRect() should be used.
BUG: 475799
Some apps, notably Tablet KCM, will rebind the tablet interface and consume all events that should be sent to the GUI toolkit.
This commit sends events to every consumer and also stores the latest cursor indexed by wl_client instead of wl_resource.
BUG:473126
Both MMB and RMB are broken because acceptedPointerTypes doesn't accept
PointerDevice.GenericPointer.
RMB is broken because there's no "desktopView" object.
BUG: 475681
Recent-ish changes meant that the X11 window is kept alive whilst an
effect may be using the window.
This changes the lifetime of the sync alarm. This is problematic in the
case of an XWayland crash, we can assume whilst an X11 client is valid
the X11 connection is also valid, but if a close animation is used the
connection might not be valid when the destructor is called.
If a repaint is scheduled in the prePaintScreen() function, we want
it to be applied in the next frame, not the current one.
Currently, it doesn't work like this because prePaintScreen() runs first
then the Compositor gathers repaints and resets them.
This is important to qtquick effects that use qtquick3d as some items in
qtquick3d schedule repaints for the next frame after synchronizing, i.e.
in OffscreenQuickView::update() which is called in prePaintScreen() by
QuickSceneEffect.
Right now screenshots of windows always have drop shadows. This change
makes the shadows optional. Resolves a 7-year-old bug report in
conjunction with an incoming change to Spectacle.
BUG: 372408
The method is called quite often during KWins lifetime.
Because the pattern is constant, we can reuse the value instead of creating a new regex every time
