When we click into the CheckBox the following effects are being enabled:
*kwin4_effect_desktopgrid
*kwin4_effect_presntwindows
*kwin4_effect_dialogparent
If one of the above effects gets disabled, then the checkbox is unchecked.
Our CheckBox can detect if our effects are enable at the start time.
Only ONE of the following effects can be active at the same
time.
*kwin4_effect_slideEnabled
*kwin4_effect_cubeslideEnabled
*kwin4_effect_fadedesktopEnabled
The EffectLoader is a subclass of AbstractEffectLoader delegating all
methods to instances of:
* BuiltInEffectLoader
* ScriptedEffectLoader
* PluginEffectLoader
It's used by the EffectsHandlerImpl and replaces the complete Effect
loading mechanism we so far found in it. This also means that KLibrary
is no longer needed to load the Effects as the PluginEffectLoader uses
the KPluginTrader, which removes lots of deprecated functionality.
REVIEW: 117054
This is a specialized subclass of AbstractEffectLoader to load binary
effect plugins. It used the KPluginTrader to find all candidates to load.
The loader is able to detect incorrect ABI versions through the
pluginVersion() and uses the methods exposed by the new
KWin::EffectPluginFactory to check whether the Effect is supported and
should be enabled by default.
The unit test for this loader comes with two plugins: one is able to be
loaded and provides a supported and enabledByDefault method which can be
tweaked during the test to get all the conditions we want to test for.
The second plugin uses an incorrect plugin version and thus cannot get
loaded.
A KWin::EffectPluginFactory is introduced which provides a specialized
create method and methods for the supported and enabledByDefault checks.
A set of KWIN_EFFECT_FACTORY macros are added which create a subclass
of this EffectPluginFactory following the approach from the
KPluginFactory macros. The macros only support json metadata thus the
QPluginTrader needs to be used.
The KWIN_EFFECT macros are removed as they are no longer needed.
KWin Core's loader is not yet adjusted to this change. This is a
preparation step for introducing a PluginEffectLoader.
