For this KDecorationOptions becomes a QObject. The changed flags from
updateSettings are removed. Instead the method just emits the proper
changed signals.
This should allow better handling in the Factories.
A factory is supposed to emit this signal whenever the decorations
need to be recrated. The DecorationPlugins inside KWin Core connect
to the signal and recreate the decorations.
This signal is supposed to replace the reset method which encoded
this information in the return value and which is already ignored.
The changed mask is going to be replaced by more specific signals so
we don't need to calculate the change mask in KWin core anymore.
We still need to call reset in the decoration plugin to check whether
a new decoration library needs to be loaded.
During startup we only create the request, the reply will be fetched
once the atom is needed.
To make proper use of this async behavior the creation of Atoms is
moved directly to the claim of the manager selection, so they can be
fetched while we wait for the previous manager selection to give up
on it.
The crash count checking does not depend on whether or not we will
be able to claim the window manager selection. As claiming the selection
can take up to one second we should try to get as many checks which do
not depend on it out.
The frameId only makes sense for a Client, in case of Unmanaged the
same window id is used as for the window() handle. Client creates the
frame and destroys it.
Given that it makes sense to let Client manage the frame properly.
The ::frameId() is therefore virtual and as base implementation it
returns the client id. Client reimplements it and returns the proper
frame id.
Method is also implemented in Deleted as it used to be passed to
deleted.
We have windows which we don't want to destroy (e.g. the managed
clients) but still would like to be able to use the nicer API.
Therefore the not creating ctor and reset method have a second bool
arg to whether destroy the window or not. Default is to keep the
RAII functionality.
There used to be an own action collection in KDE 3 times for the
block global shortcuts shortcut. But the code ws disabled and by
that I didn't see it during removing the global shortcuts blocking.
And it explains why the global shortcut blocking didn't work.
Method replaces the logic of the macros. The macros are still there
to not need to change all the code. Major difference is that the new
method uses the compile time checked connect syntax.
