Window::desktop() is obsolete. On the other hand, X11 doesn't support
having a window on several virtual desktops, so we still need it. As a
compromise, this change moves it to X11Window instead.
org.kde.kcm.ConfigModule doesn't exist anymore. Its replacement lives in
org.kde.kcmutils module now.
Note that the replacement has no "quickHelp" property, so it's been
removed. While on this, also drop "ConfigModule.buttons". It still
exists in the new ConfigModule but the default buttons should be fine.
This reverts commit 9cd52b4060.
This commit broke the adjustable scroll speed feature on Wayland. That
feature may not have been implemented in the most technically ideal way,
but simply breaking it and leaving the mouse KCM with UI control that
does nothing isn't great. Besides, there was always a simple way to
avoid any scroll-related regressions caused by this feature: reset the
scroll speed to its default value, which internally is a multiplier of 1
and exercises the same codepath that 9cd52b40 imposes on everyone.
We can come up with a better implementation for Plasma 6.
BUG: 464592
FIXED-IN: 5.27.4
Currently, managed and override-redirect windows are split in two types:
X11Window and Unmanaged. While looking at it strictly from type
perspective, this is great. But it creates other problems, e.g. we need
to put shared X11-specific code in the base Window class or mess with
"base" classes.
As an alternative solution, this change merges the Unmanaged class into
the X11Window class and disables some functionality based on the value
of isUnmanaged().
X11Window::manage() is used to create a managed Window. X11Window::track()
is used to create an unmanaged Window.
As a first step to move away from having an external service remember output settings
for KWin, this commit introduces an output manager that can load configuration files
and generate new output configurations.
It should be irrelevant to the scripts and there's no matching
abstraction on wayland.
is_shape is made protected, but it will be eventually moved to an X11
specific subclass.
Currently, the normal window lifecycle looks as follows: create Window,
wait until it's shown, add it to Workspace, wait until it's closed,
create a Deleted, copy properties from the original window to the
deleted one, destroy the original window, wait until the last deleted
window reference is dropped.
There are a couple of issues with this design: we can't nicely
encapsulate X11 or Wayland specific implementation details if they need
to be accessed for closed windows; manual copying of properties is
cumbersome and error prone and we've had a dozen of cases where effects
worked incorrectly because some properties had not been copied.
The goal of this patch is to drop Deleted and extend the lifetime of the
original window, but with a special state set: Window::isDeleted().
The main danger is that somebody can try to do something with deleted
windows that they should not do, but on the other hand, such code needs
to be guarded with relevant checks too.
When closing a window, we may need to change parent-child relationship
between windows, but we need to preserve stacking order constraints so
dialogs are placed above their parents when they're closed.
This is needed to ensure that Window::isScreenLocker() returns a good
value for closed windows. Also, it's needed to get rid of
ClientConnection::aboutToBeDestroyed() connection, which can cause
problems with window teardown.
