The decoration button configuration interface is merged into the QML
part using two list views (left buttons, right buttons) and a grid
view for all the available buttons.
This brings back the configuration for decoration plugins. As a change
to the old variant the configure button is moved into the list view
together with the preview. It is enabled/disabled depending on data
provided by the DecorationModel. For a plugin the DecorationModel
queries for a boolean "kcmodule" key in the metadata. For a theme it
invokes the slot hasConfiguration with the theme name which returns
whether the theme provides configuration.
The actual opening of the configuration is triggered from the
PreviewBridge, which uses the existing KPluginFactory to load the
KCModule. The decoration plugin must provide the keyword "kcmodule"
for it.
So far Aurorae is adjusted and provides configuration for the Plastik
decoration. The interaction with the configuration module works, but
the configuration itself for Plastik seems to be currently broken.
* 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
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).
