Because cursor warping was the default behaviour in seat_set_focus,
there may be cases where we may have been warping the cursor
unintentionally. This patch removes cursor warping from seat_set_focus
and only does it in the focus command. This is managed by a static
function in focus.c.
To know whether to warp or not, we need to know which node had focus
previously. To keep track of this easily, seat->prev_focus has been
introduced and is set to the previous in seat_set_focus.
Previously we would compare the last focus's workspace with the new
focus's workspace to determine if we need to emit an IPC
workspace::focus event. This doesn't work when moving the focused
container to a new workspace.
This adds a workspace property to the seat which stores the last emitted
workspace::focus workspace. Using this method, after moving the
container, refocusing it will trigger exactly one workspace::focus
event: from the old workspace to the new workspace.
This introduces seat_set_raw_focus: a function that manipulates the
focus stack without doing any other behaviour whatsoever. There are a
few places where this is useful, such as where we set focus_inactive
followed by another call to set the real focus again. With this change,
the notify argument to seat_set_focus_warp is also removed as these
cases now use the raw function instead.
A bonus of this is we are no longer emitting window::focus IPC events
when setting focus_inactive, nor are we sending focus/unfocus events to
the surface.
This also fixes the following:
* When running `move workspace to output <name>` and moving the last
workspace from the source output, the workspace::focus IPC event is no
longer emitted for the newly created workspace.
* When splitting the currently focused container, unfocus/focus events
will not be sent to the surface when giving focus_inactive to the newly
created parent, and window::focus events will not be emitted.
* Set focus to a floating container when clicking its title bar.
* Raise floating when user clicks title bar or decorations (in the
seat_begin functions).
* In container_at, it only returned a floating container if the user had
clicked the surface. This makes it use floating_container_at instead.
This introduces a new view_impl function: is_transient_for. Similar to
container_has_ancestor but works using the surface parents rather than
the tree.
This patch modifies view_is_visible, container_at and so on to allow
transient views to function normally when they're in front of a
fullscreen view.
* Create a view on workspace 1
* Switch to workspace 2 (on the same output) and create a floating
sticky view
* Use criteria to focus the view on workspace 1
Previously, we only moved the sticky containers when using
workspace_switch, but the above method of focusing doesn't call it. This
patch relocates the sticky-moving code into seat_set_focus_warp.
A side effect of this patch is that if you have a sticky container
focused and then switch workspaces, the sticky container will no longer
be focused. It would previously retain focus.
In seat_set_focus_warp, new_output_last_ws was only set when changing
outputs, but now it's always set. This means new_output_last_ws and
last_workspace might point to the same workspace, which means we have to
make sure we don't destroy it twice. It now checks to make sure they're
different, and to make this more obvious I've moved both calls to
workspace_consider_destroy to be next to each other.
container_flatten removes the container from the tree (via
container_replace) before destroying it. When destroying, the recent
changes to handle_seat_node_destroy incorrectly assumes that the
container has a parent.
This adds a check for destroying a container which is no longer in the
tree. If this is the case, focus does not need to be changed.
* Have multiple outputs
* Launch swaylock
* Unplug an output (possibly has to be the last "connected" one)
* The swaylock surface on the remaining output would not respond to key
events
This was happening because when the output destroys, focus was not given
to the other swaylock surface.
This patch makes focus be transferred to another surface owned by the
same Wayland client, but only if input was inhibited by the surface
being destroyed, and only if it's in the overlay layer. I figure it's
best to be overly specific and relax the requirements later if needed.
This patch removes a check in seat_set_focus_surface which was
preventing focus from being passed from a layer surface to any other
surface. I don't know of a use case for this check, but it's possible
that this change could produce issues.
* New configuration option: raise_floating
(From the discussion on https://github.com/i3/i3/issues/2990)
* By default, it still raises the window on focus, otherwise it
will raise the window on click.
To reproduce the problem, create layout
H[view V[view view view-focused]], then switch to another workspace and
have the previously focused view in the vsplit close (eg. using
criteria, or an mpv video finishing). Return to the workspace using
`$mod+<num>` and the entire vsplit would be focused. This happens
because handle_seat_node_destroy would only set a new focus if the
currently focused view or a parent was being destroyed. To fix it, it
needs to set a sibling of the destroying container to focus_inactive
regardless of the current focus, then restore current focus if needed.
This patch changes the function accordingly. Additionally:
* The function now makes an early return if the node being destroyed is
a workspace.
* set_focus has been renamed to needs_new_focus. This variable is true
if the head focus needs to be changed.
seat_get_active_child is used to get the active tiling child in a few
places, such as outputs getting their active workspace and
tabbed/stacked containers getting their visible child. When a workspace
uses a tabbed or stacked layout and contains a focused floating view,
calling seat_get_active_child on the workspace would incorrectly return
the floating view. This changes it so it will return the tiling child.
This fixes the following bug:
* Create layout T[view view] then float one of the views
* Attempt to click the tiling view to give it focus - it wouldn't work
because seat_get_active_child would return the floating view
* Make container_add_sibling's `after` argument a boolean.
* Use a constant for drop layout border
* Make thickness an int
* Add button state check
* Move comments in seat_end_move_tiling
These are the same as seat_set_focus, but accept a specific type rather
than using nodes. Doing this adds more typesafety and lets us avoid
using &con->node which looks a little ugly.
This fixes a crash that pretty much nobody would ever come across. If
you have a bindsym for "focus" with no arguments and run it from an
empty workspace, sway would crash because it assumes `container` is not
NULL.
* Was crashing when a view was moved to the scratchpad (prev focus had
no parent).
* Was crashing when a hidden scratchpad view unmaps because it has no
workspace.
When changing focus from a view in one workspace to an empty workspace
using `focus <direction>`, the view in the previous workspace would keep
focused styling. This is because the check to unfocus it was only done
in the container case and not workspace case, so it's been moved out of
both.
This commit changes the meaning of sway_container so that it only refers
to layout containers and view containers. Workspaces, outputs and the
root are no longer known as containers. Instead, root, outputs,
workspaces and containers are all a type of node, and containers come in
two types: layout containers and view containers.
In addition to the above, this implements type safe variables. This
means we use specific types such as sway_output and sway_workspace
instead of generic containers or nodes. However, it's worth noting that
in a few places places (eg. seat focus and transactions) referring to
them in a generic way is unavoidable which is why we still use nodes in
some places.
If you want a TL;DR, look at node.h, as well as the struct definitions
for root, output, workspace and container. Note that sway_output now
contains a workspaces list, and workspaces now contain a tiling and
floating list, and containers now contain a pointer back to the
workspace.
There are now functions for seat_get_focused_workspace and
seat_get_focused_container. The latter will return NULL if a workspace
itself is focused. Most other seat functions like seat_get_focus and
seat_set_focus now accept and return nodes.
In the config->handler_context struct, current_container has been
replaced with three pointers: node, container and workspace. node is the
same as what current_container was, while workspace is the workspace
that the node resides on and container is the actual container, which
may be NULL if a workspace itself is focused.
The global root_container variable has been replaced with one simply
called root, which is a pointer to the sway_root instance.
The way outputs are created, enabled, disabled and destroyed has
changed. Previously we'd wrap the sway_output in a container when it is
enabled, but as we don't have containers any more it needs a different
approach. The output_create and output_destroy functions previously
created/destroyed the container, but now they create/destroy the
sway_output. There is a new function output_disable to disable an output
without destroying it.
Containers have a new view property. If this is populated then the
container is a view container, otherwise it's a layout container. Like
before, this property is immutable for the life of the container.
Containers have both a `sway_container *parent` and
`sway_workspace *workspace`. As we use specific types now, parent cannot
point to a workspace so it'll be NULL for containers which are direct
children of the workspace. The workspace property is set for all
containers, except those which are hidden in the scratchpad as they have
no workspace.
In some cases we need to refer to workspaces in a container-like way.
For example, workspaces have layout and children, but when using
specific types this makes it difficult. Likewise, it's difficult for a
container to get its parent's layout when the parent could be another
container or a workspace. To make it easier, some helper functions have
been created: container_parent_layout and container_get_siblings.
container_remove_child has been renamed to container_detach and
container_replace_child has been renamed to container_replace.
`container_handle_fullscreen_reparent(con, old_parent)` has had the
old_parent removed. We now unfullscreen the workspace when detaching the
container, so this function is simplified and only needs one argument
now.
container_notify_subtree_changed has been renamed to
container_update_representation. This is more descriptive of its
purpose. I also wanted to be able to call it with whatever container was
changed rather than the container's parent, which makes bubbling up to
the workspace easier.
There are now state structs per node thing. ie. sway_output_state,
sway_workspace_state and sway_container_state.
The focus, move and layout commands have been completely refactored to
work with the specific types. I considered making these a separate PR,
but I'd be backporting my changes only to replace them again, and it's
easier just to test everything at once.
This moves the arrange_windows call into the arrange_layers function,
where we know the output actually needs to be arranged.
Additionally, we shouldn't set focus to the parent of an unknown
container type, because the parent may be an output and this causes a
crash because outputs can't have direct focus.
Fixes#2543
When we have type safety we'll need to have functions for
workspace_add_tiling and so on. This means the existing container
functions will be just for containers, so they are being moved to
container.c. At this point layout.c doesn't contain much else, so I've
relocated everything and removed the file.
* container_swap and its static functions have been moved to the swap
command and made static.
* container_recursive_resize has been moved to the resize command and
made static.
* The following have been moved to container.c:
* container_handle_fullscreen_reparent
* container_insert_child
* container_add_sibling
* container_add_child
* container_remove_child
* container_replace_child
* container_split
* enum movement_direction and sway_dir_to_wlr have been moved to util.c.
Side note: Several commands included layout.h which then included
root.h. With layout.h gone, root.h has to be included by those commands.
This changes the destroy functions to the following:
* output_begin_destroy
* output_destroy
* workspace_begin_destroy
* workspace_destroy
* container_begin_destroy
* container_destroy
* view_begin_destroy
* view_destroy
The terminology was `destroy` and `free`, and it has been changed to
`begin_destroy` and `destroy` respectively.
When the last output is disconnected, its workspaces will now be stashed
in the root. Upon connection of a new output they will be restored.
There is a new function `workspace_consider_destroy` which decides
whether the given workspace should be destroyed or not (ie. empty and
not visible).
Calling container_begin_destroy will no longer automatically reap the
parents. In some places we want to reap the parents and in some we
don't, so this is left to the caller.
container_reap_empty_recursive and container_reap_empty have been
combined into one function and it will recurse up the tree.
Workspaces previously had a magical `workspace->floating` container,
which had a layout of L_FLOATING and whose children were actual floating
views. This allowed some conveniences, but was a hacky solution because
the container has to be exempt from focus, coordinate transactions with
the workspace, and omit emitting IPC events (which we didn't do).
This commit changes it to be a list directly in the sway_workspace. The
L_FLOATING layout is no longer used so this has been removed as well.
* Fixes incorrect check in the swap command (it checked if the
containers had the L_FLOATING layout, but this layout applied to the
magical container).
* Introduces workspace_add_floating
This introduces the following `for_each` functions:
* root_for_each_workspace
* root_for_each_container
* output_for_each_workspace
* output_for_each_container
* workspace_for_each_container
And introduces the following `find` functions:
* root_find_output
* root_find_workspace
* root_find_container
* output_find_workspace
* output_find_container
* workspace_find_container
* container_find_child
And removes the following functions:
* container_descendants
* container_for_each_descendant
* container_find
This change is preparing the way for demoting sway_container. Eventually
these functions will accept and return sway_outputs, sway_workspaces and
sway_containers (meaning a C_CONTAINER or C_VIEW).
This change also makes it easy to handle abnormalities like the
workspace floating list, root's scratchpad list and (once implemented)
root's saved workspaces list for when there's no connected outputs.
Fixes#2467.
This commit introduces seat_get_focus_inactive_floating to supplement
seat_get_focus_inactive_tiling, and uses it during `focus mode_toggle`
which fixes a focus bug.
This also refactors the seat_get_focus_inactive functions so that they
do their selection logic themselves rather than offloading it to
seat_get_focus_by_type which was getting bloated. seat_get_focus_by_type
is now removed.
Lastly, this commit changes seat_get_focus to just return the first
container in the focus stack rather than looping and calling
seat_get_focus_by_type.
* The OP_RESIZE seat operation has been renamed to OP_RESIZE_FLOATING,
and OP_RESIZE_TILING has been introduced.
* Similar to the above, seat_begin_resize and handle_resize_motion have
been renamed and tiling variants introduced.
* resize.c's resize_tiled has to be used, so container_resize_tiled has
been introduced in resize.c to allow external code to call it.
* Removes container_floating_move_to_container, instead opting to put
that logic in container_move_to
* In the seat code, focusing a floating view now updates the pending
state only and lets the next transaction carry it over to the current
state. This is required, otherwise it would crash.
* When unfullscreening a floating container, an output check is now done
to see if it should center it.
* seat_set_focus_warp lacked a container NULL check
* view mapping code needs to use seat_get_focus_inactive
Also, seat_set_focus_warp triggered the wrong IPC event if focus was a
workspace, which resulted in swaybar not showing the workspace as
active.
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.
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.
The crash only occurs if the mouse cursor is above the tabbed container
when the last child is closed.
Introduced in 03d49490cc, over a week ago
and unnoticed until now :O
The above commit changes the behaviour of a focus change. When you
change focus, it sends pointer motion which makes the client set a new
cursor image. We already had this behaviour for workspace switching, but
this commit adds it for view switching too, such as in a tabbed
container or when closing a view.
The sequence of events that leads to the crash is:
* The last child of a tabbed container unmaps, which triggers a
`destroy` event before we've cleaned up the child or reaped the tabbed
container.
* The seat code listens to the `destroy` event and removes the seat
container from the focus stack. As part of this, it decides to set focus
to the parent (my fix alters this decision).
* When setting focus to the new parent, the container motion is sent as
per the previously mentioned commit.
* The motion code uses `container_at`, which encounters the tabbed
container and its child in a half destroyed state, and everything blows
up from there.
`con->parent` is needed because scratchpad containers don't have parents
if they're hidden, so this probably fixes a crash when a hidden
scratchpad container closes too.
The `con->parent->children->length > 1` check should catch any cases
where the parent is about to be reaped.
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
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.
This allows to send wl_pointer.enter when switching between views
in a split/tabbed layout for instance. This (1) updates the cursor
image accordingly (2) makes it unnecessary to move the mouse before
scrolling. It's harmless to always call cursor_send_pointer_motion
because in case the focused surface hasn't changed this is a no-op.
The `last_focus != NULL` condition is required otherwise
cursor_send_pointer_motion will crash when sway starts up (the
sway_output doesn't yet have a 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).
When you have an unfocused container (so one view is focused_inactive),
and you focus any other view in that container, the view with
focused_inactive was not damaged. This is because we damaged the
previous focus and new focus, but needed to damage the parent of the new
focus.
Fixes#2192.
seat_get_active_current_child is intended to return a child of the given
container which has finished its mapping transaction and is able to be
rendered on screen. The previous implementation was capable of returning
a pending child, which caused a child of a tabbed or stacked view to be
rendered prematurely while it was mapping.
seat_get_active_child is used for tabbed and stacked containers to get
the active child. The previous implementation used seat_get_focus_inactive
then ascended the tree to the child of the tabbed/stacked container, but
this fails when the workspace itself is stacked or tabbed and the most
recently active child is floating.
The new implementation takes a more simple approach, where it directly
scans the focus stack for the first immediate child which isn't the
floating container.
Fixes#2098.
This required changing container_at_cursor to container_at_coords so
that we could get the appropriate surface (and sx/xy) without moving the
cursor.
Future work:
- Simulate a cursor for clients which have not bound to wl_touch
- Keep sending motion events when moving outside the surface (#1892)
- Bind gestures to sway commands
Replaces arrange_windows() with arrange_root(), arrange_output(),
arrange_workspace() and arrange_children_of().
Also makes fullscreen views save and restore their dimensions, which
allows it to preserve any custom resize and is also a requirement for
floating views once they are implemented.
Until now, focus changing code only considered cleaning up the last focused
workspace. This commit adds removal of empty workspace from output that just
received focus on a different workspace.
