Attempting to open a GTK3 menu and activate a menu item in it,
using a single mouse motion (press-move-release), was broken due
to GTK apparently expecting to receive leave/enter events when the
cursor enters the menu (XDG popup).
To fix the issue, allow leave/enter events when the cursor is
moved between an XDG toplevel and popups of the same.
v2:
- Use (struct view *) as proxy for toplevel in comparisons
- Update seat->pressed.surface when entering/leaving popups
v3:
- Go back to using get_toplevel() rather than (struct view *)
Fix a couple of glitches seen when exiting interactive move/resize:
- Cursor briefly set to left_ptr rather than the correct cursor image
- Cursor not updated if the view being moved/resized is destroyed
Also make sure to exit interactive mode if the view is going fullscreen
(labwc gets very confused otherwise).
Code changes in detail:
- Factor out set_server_cursor() which will set the correct cursor
image for non-client areas (either XCURSOR_DEFAULT or one of the
resize cursors).
- Unify the logic from cursor_rebase() and process_cursor_motion by
factoring out cursor_update_common(). This corrects some logic
discrepancies between the two, which should be a good thing(TM).
- Remove the extra cursor_set(XCURSOR_DEFAULT) from interactive_end()
and instead rely on cursor_update_focus() to do the right thing.
- Simplify cursor_button() by just calling interactive_end() when we
want to exit interactive mode.
- Call cursor_update_focus() from view_destroy() if the view had mouse
focus or was being interactively moved/resized.
v2: Eliminate force_reenter parameters and figure out automatically
when we need to re-enter the surface.
v3: Rename wlseat -> wlr_seat.
v4: Simplify client/server cursor logic.
Corner buttons (WINDOW_MENU and CLOSE) are one more level down in
the scene-tree (see add_scene_button_corner() in ssd_part.c).
This fixes a minor issue where, when right-clicking on the CLOSE
button, the client-menu would be displayed in the wrong location.
... and use Title for the Drag (Move) and DoubleClick (Maximize)
titlebar actions, which are unexpected when the cursor is over one
of the window buttons.
The topmost view may not always be the focused view; for example,
when Audacious's main window is focused but the floating Search
Tool window remains on top of it. In that case the floating window
(not the main window) should be the first view selected in the
window switcher.
- When XDG and XWayland views are positioned (view_moved()).
- When unmanaged XWayland surfaces are mapped, unmapped, or moved.
Do not update cursor focus during an out-of-surface drag.
Along with the existing call in desktop_move_to_front(), this
should hopefully cover the majority of cases where the cursor focus
could get out-of-date, with the possible exception of layer-shell
surfaces.
At least for XWayland surfaces, handle_commit() is not always
called after map(), and as a result, the scene-graph node is never
positioned.
Not sure 100% if the same can occur with XDG surfaces, but the
extra view_moved() call should be harmless, so add it there too
for consistency.
- Eliminate multiple "return" paths in unmanaged_handle_unmap(), which
were a bug waiting to happen.
- Use wl_list_for_each_reverse() rather than wl_list_for_each() to find
the topmost (most-recently-created) unmanaged surface.
- Only call desktop_focus_topmost_mapped_view() if the unmapped surface
was actually focused.
