It's 2014 and we don't have to wait half a minute for an application
to start. In fact we mostly get false positives due to applications
not handling correctly startup notifications for already running
instances (e.g. click on link in email).
So let's reduce to a default which doesn't look like a broken setup.
REVIEW: 115046
Videos for the following effects are added:
* Dim Inactive
* Dim Screen for Administration Mode
* Invert
* Looking Glass
* Magnifier
* Mouse Click
* Track Mouse
* Zoom
Link for Present Windows video fixed.
Most effects had a "collection" for one action. We don't need the
action collection, all it was used for is setting the object name.
With the removal of KActionCollection the effects do not need to link
XmlGui any more, though the dependency is still pulled in through
plasma.
Client used to have dedicated methods for different icon sizes instead
of combining all pixmaps into one QIcon. This resulted in various parts
of KWin having different access to the icons:
* effects only got one pixmap of size 32x32
* decorations only got the 16x16 and 32x32 pixmaps combined into a QIcon
* tabbox could request all icon sizes, but only as pixmap
Now all sizes are available in one QIcon allowing to easily access the
best fitting icon in a given UI.
With QtQuick2 it's possible that the scene graph rendering context either
lives in an own thread or uses the main GUI thread. In the latter case
it's the same thread as our compositing OpenGL context lives in. This
means our basic assumption that between two rendering passes the context
stays current does not hold.
The code already ensured that before we start a rendering pass the
context is made current, but there are many more possible cases. If we
use OpenGL in areas not triggered by the rendering loop but in response
to other events the context needs to be made current. This includes the
loading and unloading of effects (some effects use OpenGL in the static
effect check, in the ctor and dtor), background loading of texture data,
lazy loading after first usage invoked by shortcut, etc. etc.
To properly handle these cases new methods are added to EffectsHandler
to make the compositing OpenGL context current. These calls delegate down
into the scene. On non-OpenGL scenes they are noop, but on OpenGL they go
into the backend and make the context current. In addition they ensure
that Qt doesn't think that it's QOpenGLContext is current by calling
doneCurrent() on the QOpenGLContext::currentContext(). This unfortunately
causes an additional call to makeCurrent with a null context, but there
is no other way to tell Qt - it doesn't notice when a different context
is made current with low level API calls. In the multi-threaded
architecture this doesn't matter as ::currentContext() returns null.
A short evaluation showed that a transition to QOpenGLContext doesn't
seem feasible. Qt only supports either GLX or EGL while KWin supports
both and when entering the transition phase for Wayland, it would become
extremely tricky if our native platform is X11, but we want a Wayland
EGL context. A future solution might be to have a "KWin-QPA plugin" which
uses either xcb or Wayland and hides everything from Qt.
The API documentation is extended to describe when the effects-framework
ensures that an OpenGL context is current. The effects are changed to
make the context current in cases where it's not guaranteed. This has
been done by looking for creation or deletion of GLTextures and Shaders.
If there are other OpenGL usages outside the rendering loop, ctor/dtor
this needs to be changed, too.
It's basically a run of the port-cmake.sh script in here, mostly the changes
are the following:
- Using KF5::* targets
- Using the proper macros, following recent developments in frameworks
Hiding and Showing the close window button all the time can result in
the window not having a proper content. To fix this issue we keep the
window around, but just don't show it. For this the CloseWindowView
inherits from QObject and delegates the needed calls to the nested
QQuickView.
* KDE/4.11:
Remove assertion in KDecorationUnstable's constructor.
SVN_SILENT made messages (.desktop file)
Cursor Theme KCM: Show correct resize cursor in preview for themes without a file called "size_fdiag"
Fixed missing signal/slot connection:
Fix zoom effect cursor position on initial zoom in.
SVN_SILENT made messages (.desktop file)
Don't show borders for a maximized Laptop client
Always use PositionCenter for maximized windows
Fix click on trash plasmoid when on desktop and widgets are unlocked
