Making it possible for clients to call setDesiredSize directly, The idea is that under Wayland, the panel calls this intead of setGeometry, not trying to set an abosulute geometry that might cause the panel sized wrongly, but just sets an hint which will ensure the panel won't overlap another one used by https://invent.kde.org/plasma/plasma-workspace/-/merge_requests/5437 CCBUG:489703
LayerShellQt
This component is meant for applications to be able to easily use clients based on wlr-layer-shell.
Here you can read about what the protocol does and how shells work: https://drewdevault.com/2018/07/29/Wayland-shells.html

Usage
CMake
To use it from a CMake project you'll need to:
find_package(LayerShellQt REQUIRED)
Then it will offer us the target LayerShellQt::Interface that we can link to to get access to this framework.
C++
You can use LayerShellQt::Shell::useLayerShell(); to enable it before any clients are created.
The class LayerShellQt::Window will give us access to surface-specific settings. We can get it by using LayerShellQt::Window::get(window) on whatever QWindow we need to tweak.
