There were two problems preventing it from working:
1. The placement tracker didn't handle them correctly; now it sets the custom tile mode
after moving the window to its location
2. The window code used `output()` instead of `moveResizeOutput()`, which means when KWin
just moved the window to a different screen and immediately changes the tile mode
afterwards, it would tile the window on the wrong output
There were two problems:
1. Workspace interacted with the tile mode of windows before inhibiting
the placement tracker, so the wrong window state was stored in the placement
tracker
2. Window::setQuickTileMode is unintuitive and has some undesired side effects,
meant to handle quick tiling with keyboard shortcuts and by dragging the
window with a mouse specifically. This commit just works around that by
un-setting the tile mode first
BUG: 461886
The quicktileMode member now is just for the requested tile mode, base the "real" mode only on m_tile.
The requested tile mode is used for double buffering, to look and behave just like requestedMAximizeMode() which is updated immediately, but needs to acknowledge the configure request and render for quickTileMode() (and the right tile() instanced to be associated) to be updated accordingly
Geometry restores were only saved when maximize or fullscreen changed, which is
not the only time the geometry restores change. This adds a signal to Window for
that, which fixes a few bugs with windows being moved between screens while
maximized or fullscreened
* speeds up incremental builds as changes to a header will not always
need the full mocs_compilation.cpp for all the target's headers rebuild,
while having a moc file sourced into a source file only adds minor
extra costs, due to small own code and the used headers usually
already covered by the source file, being for the same class/struct
* seems to not slow down clean builds, due to empty mocs_compilation.cpp
resulting in those quickly processed, while the minor extra cost of the
sourced moc files does not outweigh that in summary.
Measured times actually improved by some percent points.
(ideally CMake would just skip empty mocs_compilation.cpp & its object
file one day)
* enables compiler to see all methods of a class in same compilation unit
to do some sanity checks
* potentially more inlining in general, due to more in the compilation unit
* allows to keep using more forward declarations in the header, as with the
moc code being sourced into the cpp file there definitions can be ensured
and often are already for the needs of the normal class methods
If a window was moved by the user, it got effectively blacklisted from being
ever restored again. Instead of only tracking the last restore point, compare the
current window state with the state it had when the output configuration was last
seen. If either that or the last restore point match the window, restore the old
window state.
The Window::moveResizeOutput() property is used to track the output
where the window is expected to land after the move or resize operation
completes.
This can be used to decouple the current output from the next output,
which allows us to send better xdg_toplevel.configure_bounds events or
make windows stick to outputs while keeping Window::output() in sync
with the current output layout.
