The .clang-format file is based on the one in ECM except the following
style options:
- AlwaysBreakBeforeMultilineStrings
- BinPackArguments
- BinPackParameters
- ColumnLimit
- BreakBeforeBraces
- KeepEmptyLinesAtTheStartOfBlocks
Not sure if this was left out on purpose as a kind of deprecation.
It would be necessary to allow port the tabbox switchers to the newer 3.0 API and use their components (such as `Workspace`)
Probably for `Plasma/5.25` now.
Currently, thumbnail items are rendered by kwin. This means that qtquick
code cannot do things such as applying shader effects to window thumbnails
or simply draw custom controls on top of thumbnails.
With this change, task switchers and qml extensions will be able to
place their own contents on top of thumbnails and apply custom effects
to them.
In order to integrate window thumbnails, a window is rendered on kwin
side using its own opengl context. A fence is inserted in the command
stream to ensure that the qtquick machinery doesn't start using the
offscreen texture while there are still rendering commands being executed.
Thumbnails are rendered into offscreen textures as we don't have full
control over when qtquick windows render their contents and to work around
the fact that things such as VAOs can't be shared across OpenGL contexts.
WindowThumbnailItem and DesktopThumbnailItem act as texture providers.
Once in a while, we receive complaints from other fellow KDE developers
about the file organization of kwin. This change addresses some of those
complaints by moving all of source code in a separate directory, src/,
thus making the project structure more traditional. Things such as tests
are kept in their own toplevel directories.
This change may wreak havoc on merge requests that add new files to kwin,
but if a patch modifies an already existing file, git should be smart
enough to figure out that the file has been relocated.
We may potentially split the src/ directory further to make navigating
the source code easier, but hopefully this is good enough already.
