This MR does several things as a followup to
https://invent.kde.org/plasma/plasma-mobile/-/merge_requests/748:
- Use the word "lock" instead of "sleep" since we are locking the
device, not putting it to sleep
- Simplify usage by using existing MouseAreas instead of including our
own for this feature (I encountered several focus captures in folio that prevented the
SwipeArea from getting events)
Add a settings page to halcyon, which allows for toggling whether the
wallpaper is blurred and double tapping on the homescreen to lock the
device. This also does a bit of refactoring for folio and halcyon to
share the same wallpaper blurring item.
BUG: 486554
In Qt6 a bunch of weird behavior started happening with handlers which broke a bunch of things only in touch.
Remove the HoverHandler here which apparently wasn't used for anything, and causes any MouseArea to stop sending clicked and pressAndHold signals. DragHandler also appears to have stopped working with touch (for the folder close swipe gesture), but that involves far more rewriting to replace...
Currently you need to go from Settings -> "Switch between homescreens and more wallpaper options" to access the advanced wallpaper settings. Add a button directly into the wallpaper selector for this.
Contributes to #317
This refactor changes WindowMaximizedTracker from being a Singleton, and allows for it to be created in a way such that screens can be filtered out.
This fixes external screens from having their homescreen "zoom out" when an app is maximized on another screen.
This (partially) reverts commit 127bbdf653.
Only incorrect changes from Kirigami.Units.largeSpacing to
Kirigami.Units.gridUnit are reverted. Only Plasma.Units were buggy.
The eventual goal is to have as few singletons with state as possible in the mobileshell component when it is imported into components such as the lockscreen.
This doesn't fully accomplish it, but moves the audio provider singleton to MobileShellState, which will eventually need to be prevented from importing into non plasmashell processes.
This also disables the sound feedback when changing volume, since it can be a source of lag when showing the applet.
This allows us in the future to use mobileshell without having the WindowUtil singleton loaded (which does a bunch of wayland calls that aren't necessary for most applications).
