Instead, set ctx.type = LAB_NODE_LAYER_SURFACE for both layer-surfaces
and layer-subsurfaces.
This patch preserves the existing behaviors:
- Pressing a subsurface of an on-demand layer-surface gives pointer
focus to the subsurface, but gives keyboard focus to the parent
layer-surface (related: a5fcbfaf).
- Pressing a subsurface of a layer-surface doesn't close a popup
(related: a89bcc3c).
struct ssd_part and struct node_descriptor seem to have essentially the
same purpose: tag a wlr_scene_node with some extra data indicating what
we're using it for.
Also, as with enum ssd_part_type (now lab_node_type), ssd_part is used
for several types of nodes that are not part of SSD.
So instead of the current chaining (node_descriptor -> ssd_part), let's
flatten/unify the two structs.
In detail:
- First, merge node_descriptor_type into lab_node_type.
- Add a separate view pointer in node_descriptor, since in the case of
SSD buttons we need separate view and button data pointers.
- Rename ssd_part_button to simply ssd_button. It no longer contains
an ssd_part as base.
- Add node_try_ssd_button_from_node() which replaces
node_ssd_part_from_node() + button_try_from_ssd_part().
- Factor out ssd_button_free() to be called in node descriptor destroy.
- Finally, get_cursor_context() needs a little reorganization to handle
the unified structs.
Overall, this simplifies the code a bit, and in my opinion makes it
easier to understand. No functional change intended.
ssd_part_type contains several node types that are not actually part of
server-side decorations (ROOT, MENU, OSD, etc.)
Rename it accordingly and move it to a common location, along with some
related conversion/comparison functions.
view_restore_to() (which is just set_maximized() + view_move_resize())
hasn't aged well and doesn't line up with typical usage anymore:
- it's missing view_set_untiled(), which has to be called separately
- it always forces view_move_resize() even when that's not needed
- it doesn't allow un-maximizing only one axis (see next commit)
- the fullscreen check is unnecessary (already checked in callers)
Eliminate it and just expose view_set_maximized() instead.
No functional change intended in this commit.
- add LAB_WINDOW_TYPE_INVALID in place of literal -1
- document more clearly that enum lab_view_criteria is a bitset
- other one-off replacements of integer values/types for consistency
Note: variables of type enum lab_view_criteria are already used
extensively throughout the code to contain combinations of the declared
enum values. I am not introducing any new usage here, just changing the
single uint32_t to be consistent with all the other usages.
I like the new common/edge.h. I don't like how inconsistently we use it.
Current situation:
- enum wlr_edges and wlr_direction are designed to be used as bitset,
and are defined compatibly
- enum lab_edge is *also* designed to be used as bitset, but
incompatible with the others (LEFT/RIGHT come before UP/DOWN)
- we use an inconsistent mix of all three *AND* uint32_t (usually with
the WLR_EDGE constants rather than the LAB_EDGE constants), and
convert between them on an ad-hoc basis, sometimes implicitly
Let's clean this up:
- reorder enum lab_edge to be compatible with the two wlr enums
(check this by static_assert)
- use TOP/BOTTOM naming rather than UP/DOWN (matches wlr_edges)
- add constants for the remaining possible combinations of the 4 edges
- use lab_edge for all internal edge/direction fields, consistently
- add lab_edge_is_cardinal() as a sanity check before casting to
enum wlr_direction, and then eliminate all of direction.c/h
Instead of "enum wlr_edges direction", we now have
"enum lab_edge direction" which is not that much better. At least we
are now clear that we're overloading one enum with two meanings.
update_keycodes_iter() currently has 4(!) levels of nested loops, which
makes the logic (especially the break/continue statements) difficult to
understand. The logic also appears to continue looping uselessly after
a given keycode has already been added to a keybind.
Refactor by adding some small utility functions:
- keybind_contains_keycode()
- keybind_contains_keysym()
- keybind_contains_any_keysym()
No functional change intended.
Fixes up e530f43.
When IME (e.g. fcitx5) is killed, relay->input_method is destroyed and
then relay->input_method->keyboard_grab is destroyed, which causes null
pointer dereference and crashes labwc.
Possible solutions are:
- Let wlroots keep emitting keyboard grab as `data` from keyboard grab's
destroy handler just like before
- Let wlroots destroy keyboard grab before input method
- Let compositor store keyboard grab as relay->keyboard_grab
But let's just revert the change in e530f43 for now.
This is a common practice in C projects, which simply enforces that
each header must compile cleanly without implicit dependencies on
other headers (see also the previous commit).
Hi-res mice produces mulitple scroll events with `delta_discrete` != 0
during a single "click". This patch makes them trigger `Scroll` actions
only when the accumulated `delta_discrete` exceeds 120 (= 1 click).
See https://lists.freedesktop.org/archives/wayland-devel/2019-April/040377.html
for how hi-res scroll events are reported.
The workarounds added in #2498 and #2437 fixed stuck key/modifier bug
caused by wlroots commit e218990. But now that the commit was reverted in
0.19, the workarounds are no longer needed.
Removing the workarounds also fixes a minor regression with Fcitx5+Firefox
that pressing Ctrl+Enter in an input box causes stuck modifier.
Having a hover effect visible without interaction looks out of
place when there is no cursor (the cursor becomes hidden for/after
touch interaction until next mouse or tablet interaction). Just
clear the hover effect after touch-up to prevent this.
Note that SSD hover effects are still shown during touch-move and
touch-down.
Only use the touch protocol when no labwc menu is open.
This ensure that labwc menus will be closed on first touch
down/up since cursor emulation takes care of closing a
menu.
This prevents that a labwc menu stay open during touch
interactions in native touch mode.
It doesn't matter much since those are about the combination
of tablet and tablet tool. That said, this feels slightly more
natural.
As a consequence we always create a tablet tool and decide
indirectly via `tablet_get_coords()` and the returning surface
if mouse emulation should be used or not. Now we can also
add a `motion_mode` to the tablet tool which is slightly cleaner.
Omit cursor notifications from a pointer when a tablet
tool (stylus/pen) is in proximity. This is equivalent
to `handle_request_set_cursor()` and prevents a resize
cursor for out-of-surface scrolling with a tablet tool in
recent GTK4 (which uses the cursor shape protocol).
Using mouse emulation for a tablet tool mouse is just a practical
decision to let such a tool work more smootly, e.g. it avoids weird
menu issues in GTK applications. Since such a tool doesn't have
pen specifix axis like pressure or distance, no functionality is lost.
A solution fully in line with the protocol, which would pass the tool
mouse buttons to the client, would leave us with e.g. non-working
buttons in current GTK4 since they don't handle the buttons
reported from the tool mouse.
May be this changes in future. But for now, let's just be practical.
