The cube effect was relying on paintWindow() using the generic shader
without explicitly telling it to do so. This makes the cube effect
work with dynamic shaders.
Effects currently modify the matrices by reading back the uniform
values from the shader they assume will be used to paint the window,
set new values for the uniforms, call paintWindow(), and then restore
the uniforms to their previous values.
This is both slow and unreliable, and will not work with dynamically
generated shaders.
This patch solves the problem by putting the matrices in
WindowPaintData and making it the responsibility of the paintWindow()
implementation to set the uniforms.
This adds new API in ShaderManager that makes it possible to request a
shader based on a set of traits. ShaderManager generates these shaders
on demand and caches them in a hash table.
* Border Sizes
* Close menu double click
Both are added to the Settings and exposed in the decoration kcm.
As it started to no longer scale the kcm uses a ui file.
Still missing:
* buttons
* custom decoration configuration
* GHNS
* search
The DecorationShadow supports the concept of sharing shadows between
multiple Decorations and this is supported by our Shadow class. But
still the created GLTextures were not shared.
This change introduces a sharing mechanismn for all GLTextures created
for a DecorationShadow. Thus if two decorations share the same
DecorationShadow they will also share the same GLTexture.
QQuickRenderControl brings a few advantages for the usage in Aurorae:
* can create an offscreen window
* eliminate the need for mutex as we control the rendering
* control the tear down of the QML scene (no more crashes in Qt)
In future we can further improve this, by sharing the context, so
that we can use the FBO texture directly. But this first needs
some more work in KWin core.
As we don't hard depend on Qt 5.4 yet it's using ifdefs. Once we have
Qt 5.4 the old code will be removed.
The Compositor is destroyed before the Client and Decorations are
destroyed on shutdown. This meant the Decorations reacted needlessly
on the alpha channel supported. E.g. Aurorae recreated the Decoration
and most likely crashed in Qt.
With this change the signal gets disconnected and the Decorations
just don't do anything.
When a Client gets created the ::createDecoration method is invoked
from ::manage which is called before the Client is added to the
ClientList in Workspace. Thus processing the update fails in the
DecorationBridge as it cannot find the Client.
By delaying to the end of the event cycle we can be sure that the
Client is completely managed and that the scheduled repaint doesn't
fail.
This fixes the missing repaint when a Client starts as inactive.
The test is flaky during the wait for Xephyr. Giving it more time should
hopefully make it more reliable.
The better way would be to switch to the command line argument
-displayfd pipeFd
unfortunately the Xephyr on the CI system does not yet support this
command line argument.
Adjust all components to use the QSharedPointer. Aurorae obviously has
to create a QSharedPointer, Shadow holds a QSharedPointer for the
DecorationShadow (advantage: is kept when the Decoration is destroyed),
and the KCM needs to add a property on PreviewItem to get access to the
Shadow. It's no longer a Q_PROPERTY on Decoration and we cannot re-add
it as a dynamic property (cannot be read from QML side).
if the index is 0, we close the circle, but if the
index is -1 (invalid) we're "somewhere" and step
into the focus chain - reasonably at the beginning
