Layer shell clients may leave the output on which to display a layer
surface up to the compositor. Instead of always putting such surfaces
on the first output use the focused output of the default seat.
This command takes a mode, modifiers, button/event name, and pointer
action as arguments. It stores these in the config data structure.
The currently available pointer actions are move-view and resize-view,
which replace the previously hard-coded functionality.
Closing the hovered view with middle click has temorarily been removed
until it is decided if we wish to make this another special pointer
action or perhaps allow running any arbitrary command (which would of
course include close).
There is now a single iter() function which accepts a filter and context
allowing users of the api to filter the views in any arbitrary way. This
change allowed for a good amount of code cleanup, and this commit also
ensures that the correct properties are checked in each case, including
the new View.destroying field added in the previous commit. This fixes
at least one crash involving switching focus to a destroying view.
Focus was made double-buffered in 96a91fd. However, much of the code
still behaved as if focus was separate from the transaction system.
This commit completes the work started in 96a91fd and ensures that
focus is applied consistently in a single transaction.
- require the caller to use Root.startTransaction() directly
- introduce View.applyPending() to unify logic
- introduce View.shouldTrackConfigure() to unify more logic
- update all callsites to intelligently rearrange only what is necessary
When a button is held down and the cursor leaves a surface, events now
continue to be sent to the client. This allows e.g. dragging a scroll
bar from outside the surface.
- Double buffering focus state ensures that border color is kept in sync
with the transaction state of views in the layout.
- Using a counter instead of a bool will allow for proper handling of
multiple seats. This is done in the same commit to avoid more churn in
the future.
This simplifies the handling of the current/pending tags and will be
used in the future for atomic layout updates involving layer surface
exclusive zones.
This is in preperation for fullscreen support which will add another
mode to this enum.
This commit also fixes a bug that allowed clicking floating views though
layout views in some cases.
