When a container is moved from, say, workspace 1 to workspace 2, workspace 2 is focused in order to arrange the windows before focus is moved back to workspace 1, which caused a workspace:focus event from workspace 2 to workspace 1 to be emitted. This commit inhibits that event.
Fixes#2364.
Suppose a view is 600px wide, and we tell it to resize to 601px during a
resize operation. We create a transaction, save the 600px buffer and
send the configure. This buffer is saved into the associated
instruction, and is rendered while we wait for the view to commit a
601px buffer.
Before the view commits the 601px buffer, suppose we tell it to resize
to 602px. The new transaction will also save the buffer, but it's still
the 600px buffer because we haven't received a new one yet.
Then suppose the view commits its original 601px buffer. This completes
the first transaction, so we apply the 601px width to the container.
There's still the second (now only) transaction remaining, so we render
the saved buffer from that. But this is still the 600px buffer, and we
believe it's 601px. Whoops.
The problem here is we can't stack buffers like this. So this commit
removes the saved buffer from the instructions, places it in the view
instead, and re-saves the latest buffer every time the view completes a
transaction and still has further pending transactions.
As saved buffers are now specific to views rather than instructions, the
functions for saving and removing the saved buffer have been moved to
view.c.
The calls to save and restore the buffer have been relocated to more
appropriate functions too, favouring transaction_commit and
transaction_apply rather than transaction_add_container and
transaction_destroy.
Fixes the render and container_at order for popups.
Fixes#2210
For rendering:
* render_view_surfaces has been renamed to render_view_toplevels
* render_view_toplevels now uses output_surface_for_each_surface (which
is now public), as that function uses wlr_surface_for_each_surface which
doesn't descend into popups
* Views now have a for_each_popup iterator, which is used by the
renderer to render the focused view's popups
* When rendering a popup, toplevels (xdg subsurfaces) of that popup are
also rendered
For sending frame done, the logic has been updated to match the
rendering logic:
* send_frame_done_container no longer descends into popups
* for_each_popup is used to send frame done to the focused view's popups
and their child toplevels
For container_at:
* floating_container_at is now static, which means it had to be moved
higher in the file.
* container_at now considers popups for the focused view before checking
containers.
* tiling_container_at has been introduced, so that it doesn't call
container_at recursively (it would check popups recursively if it did)
Now 'repeat_delay' and 'repeat_rate' control the initial delay
and rate (per second) of repeated binding invocations.
If the repeat delay is zero, binding repetition is disabled.
When the repeat rate is zero, the binding is repeated exactly
once, assuming no other key events intervene.
Each sway_keyboard is provided with a wayland timer event source.
When a valid keypress binding has been found, a callback to
handle_keyboard_repeat is set. Any key event will either clear
the callback or (if the new key event is a valid keypress binding)
delay the callback again.
This introduces seat_get_focus_inactive_tiling and updates
`focus mode_toggle` to use it instead, because the previous method
wasn't guaranteed to return a tiling view.
Things worth noting:
* When a fullscreen view unmaps, the check to unset fullscreen on the
workspace has been moved out of view_unmap and into container_destroy,
because containers can be fullscreen too
* The calls to `container_reap_empty_recursive(workspace)` have been
removed from `container_set_floating`. That function reaps upwards so it
wouldn't do anything. I'm probably the one who originally added it...
* My fix (b14bd1b0b1) for the tabbed child
crash has a side effect where when you close a floating container, focus
is not given to the tiled container again. I've removed my fix and
removed the call to `send_cursor_motion` from `seat_set_focus_warp`. We
should consider calling it from somewhere earlier in the call stack.
After setting the keymap, try to enable NumLock and disable CapsLock.
This only works if sway has the xkb master state and controls the keyboard.
Prepare configuration settings for later use as well.
The rendering code doesn't use the exclusive input surface at all
anymore to decide to skip rendering of shell surfaces. This fixes
a weird situation in which a client requests exclusive input but
isn't an overlay layer surface.
The renderer also renders all overlay surfaces in this situation,
not just one. This simplifies the code and fixes rendering when
there are more than one overlay surfaces (e.g. for a virtual
keyboard to type the lockscreen password).
The mouse binding logic is inspired/copied from the
keyboard binding logic; we store a sorted list of the
currently pressed buttons, and trigger a binding when
the currently pressed (or just recently pressed, in
the case of a release binding) buttons, as well as
modifiers/container region, match those of a given
binding.
As the code to execute a binding is not very keyboard
specific, keyboard_execute_command is renamed to
seat_execute_command and moved to where the other
binding handling functions are. The call to
transaction_commit_dirty has been lifted out.
First, the existing sway_binding structure is given an
enumerated type code. As all flags to bindsym/bindcode
are boolean, a single uint32 is used to hold all flags.
The _BORDER, _CONTENTS, _TITLEBAR flags, when active,
indicate in which part of a container the binding can
trigger; to localize complexity, they do not overlap
with the command line arguments, which center around
_TITLEBAR being set by default.
The keyboard handling code is adjusted for this change,
as is binding_key_compare; note that BINDING_LOCKED
is *not* part of the key portion of the binding.
Next, list of mouse bindings is introduced and cleaned up.
Finally, the binding command parsing code is extended
to handle the case where bindsym is used to describe
a mouse binding rather than a keysym binding; the
difference between the two may be detected as late as
when the first key/button is parsed, or as early as
the first flag. As bindings can have multiple
keycodes/keysyms/buttons, mixed keysym/button sequences
are prohibited.
Implements the following commands:
* move scratchpad
* scratchpad show
* [criteria] scratchpad show
Also fixes these:
* Fix memory leak when executing command with criteria
(use `list_free(views)` instead of `free(views)`)
* Fix crash when running `move to` with no further arguments
This allows to update the title even if the view doesn't commit.
This is useful e.g. when a terminal sets its toplevel title to
the currently running command and when the view isn't visible.
Also does a few other related things:
* Now uses enum wlr_edges instead of our own enum resize_edge
* Now uses wlr_xcursor_get_resize_name and removes our own
find_resize_edge_name
* Renames drag to move for consistency
This implements the following:
* `floating_modifier` configuration directive
* Drag a floating window by its title bar
* Hold mod + drag a floating window from anywhere
* Resize a floating view by dragging the border
* Resize a floating view by holding mod and right clicking anywhere on
the view
* Resize a floating view and keep aspect ratio by holding shift while
resizing using either method
* Mouse cursor turns into resize when hovering floating border or corner
The directive sets the timeout before an urgent view becomes normal
again after switching to it from another workspace.
Also:
* When an xwayland surface removes the urgent hint while the timer is
active, we now ignore the request. This happens as soon as the view
receives focus, so it was effectively making the timer pointless.
* The timeout is now only applied when switching to it from another
workspace.
As well as ignoring scroll events on status elements when click_events
is enabled.
Previously, using the scroll wheel on a workspace button would switch to
that workspace instead of scrolling through them. Clicks and scrolling
on status elements would always be processed by swaybar, too. So in case
you were using scrolling as volume control on a status item, swaybar
would additionally scroll through your workspaces.
This removes the urgency stuff from the commit handler and puts it in a
new set_hints handler instead. This allows the xwayland surface to
become urgent without having to commit (which doesn't happen if it's on
an non-visible workspace).
Introduces a command to manually set urgency, as well as rendering of
urgent views, sending the IPC event, removing urgency after focused for
one second, and matching urgent views via criteria.
Rather than maintain copies of the entire focus stack, this PR
transactionises the focus by introducing two new properties to the
container state and using those when rendering.
* `bool focused` means this container has actual focus. Only one
container should have this equalling true in its current state.
* `struct sway_container *focus_inactive_child` points to the immediate
child that was most recently focused (eg. for tabbed and stacked
containers).
We currently have several ways of setting debug flags, including command
line arguments, environment variables, and compile-time macros. This
replaces the lot with command line flags.
This PR changes the way we handle transactions to a more simple method.
The new method is to mark containers as dirty from low level code
(eg. arranging, or container_destroy, and eventually seat_set_focus),
then call transaction_commit_dirty which picks up those containers and
runs them through a transaction. The old methods of using transactions
(arrange_and_commit, or creating one manually) are now no longer
possible.
The highest-level code (execute_command and view implementation
handlers) will call transaction_commit_dirty, so most other code just
needs to set containers as dirty. This is done by arranging, but can
also be done by calling container_set_dirty.
This commit introduces a scroll_button option, which is intended to be
used with scroll_method. Now user can edit his sway config and add an
scroll_button option to device section.
The only user of this function would copy the string right away
to get rid of the const flag anyway, and freeing a const string
afterwards might work but is not meant to be done according to the
json-c API.
wl_event_source_remove() is illegal after display has been destroyed,
so just destroy everything when we still can.
