* 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.
This replaces view.using_csd with a new border mode: B_CSD. This also
removes sway_xdg_shell{_v6}_view.deco_mode and
view->has_client_side_decorations as we can now get these from the
border.
You can use `border toggle` to cycle through the modes including CSD, or
use `border csd` to set it directly. The client must support the
xdg-decoration protocol, and the only client I know of that does is the
example in wlroots.
If the client switches from SSD to CSD without us expecting it (via the
server-decoration protocol), we stash the previous border type into
view.saved_border so we can restore it if the client returns to SSD. I
haven't found a way to test this though.
This adds a `con` argument to `execute_command` which allows you to
specify the container to execute the command on. In most cases it leaves
it as `NULL` which makes it use the focused node. We only set it when
executing `for_window` criteria such as when a view maps. This means we
don't send unnecessary IPC focus events, and fixes a crash when the
criteria command is `move scratchpad` (because we can't give focus to a
hidden scratchpad container).
Each of the shell map handlers now check to see if the view has a
workspace. It won't have a workspace if criteria has moved it to the
scratchpad.
When destroying an idle-inhibiting client, idle_inhibit_v1_check_active can get
called from transaction_progress_queue on a view with a null container.
view_is_visible does not handle a view in this state.
This does the following:
* Adds a baseline argument to get_text_size (the baseline is the
distance from the top of the texture to the baseline).
* Stores the baseline in the container when calculating the title
height.
* Takes the baseline into account when calculating the config's max font
height.
* When rendering, pads the textures according to the baseline so they
line up.
There was code that attempted to fill in the gap below the title texture
when the texture isn't tall enough, but this only worked when the output
was positioned at 0,0. The reason is that render_rect expects a box
passed in a hybrid layout-local/output-buffer-local system, and we were
passing purely output-buffer-local. I've added a comment documenting
this.
By the way, we can't use layout-local coordinates for the rectangle box
because in some cases we set the box based on a texture size. Texture
sizes are buffer-local, and we'd have to divide them to bring it back to
layout-local which means losing precision. We could use
output-buffer-local coordinates for the box, but this would require
translating the coordinates from layout-local to output-buffer-local in
many places during rendering.
This patch also vertically centers the text inside the title bar.
This fixes pinentry-gtk-2, but might make other views floating which
would otherwise be tiled. This patch is more of a trial which could end
up becoming a permanent fix.
When rendering, the workspace for the output needs to be retrieved from
the output's `current` state. output_get_active_workspace returns the
pending workspace, which crashes if the pending workspace is new and
hasn't completed a transaction yet.
Suppose the following:
* Transactions are already in progress - say transaction A.
* View A maps, which creates transaction B and appends it to the
transaction queue.
* View B maps, which creates transaction C and appends it to the queue.
* View A unmaps, which creates transaction D and appends it to the
queue.
* Transaction A completes, so transaction B attempts to save View A's
buffer, but this doesn't exist so it saves nothing.
* Rendering code attempts to render View A, but there is no saved buffer
nor live buffer that it can use.
Rather than implement an elaborate solution for a rare circumstance,
I've take the safe option of just not rendering anything for that view.
It means that if you reproduce the scenario above, you might get the
title and borders rendered but no surface.
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.
Depends on https://github.com/swaywm/wlroots/pull/1222.
I don't know of a program that sets the state to modal without setting
the window type, but I know the modal property works because logging the
property shows it's true for the Firefox Open File dialog.
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 collecting focus to save into the transaction state, the workspace
needs to look in the tiling list only.
As seat_get_focus_inactive_tiling returns any descendant, the list also
needs to be traversed back up to the direct child of the workspace.
Fixes#2532
When there's multiple transactions in the queue, sway can take a
shortcut by checking if they all operate on the same set of containers.
If they do, it can skip all but the last transaction. The way we tested
for transactions which used the same containers was to exclusive-or
their con IDs together, but this has proved not only to be ineffective
but also has the potential to make sway crash.
This patch replaces the exclusive-or with a loop and container
comparison.
* In layout command, arrange parent of parent - not sure why this is
needed but it is
* Remove gap adjustment when rendering
* Workspace should use outer gaps, not inner
* Add exceptions for tabbed and stacked containers
* Don't mess with gap state when splitting a container
This commit changes the arrange code in a way that will support type
safe arguments.
The arrange_output et al functions are now public, however I opted not
to use them directly yet. I've kept the generic arrange_windows there
for convenience until type safety is fully implemented. This means this
patch has much less risk of breaking things as it would otherwise.
To be type safe, arrange_children_of cannot exist in its previous form
because the thing passed to it could be either a workspace or a
container. So it's now renamed to arrange_children and accepts a list_t,
as well as the parent layout and parent's box.
There was some code which checked the grandparent's layout to see if it
was tabbed or stacked and adjusted the Y offset of the grandchild
accordingly. Accessing the grandparent layout isn't easy when using type
safe arguments, and it seemed odd to even need to do this. I determined
that this was needed because a child of a tabbed container would have a
swayc Y matching the top of the tab bar. I've changed this so a child of
a tabbed container will have a swayc Y matching the bottom of the tab
bar, which means we don't need to access the grandparent layout. Some
tweaks to the rendering and autoconfigure code have been made to
implement this, and the container_at code appears to work without
needing any changes.
arrange_children_of (now arrange_children) would check if the parent had
gaps and would copy them to the child, effectively making the
workspace's gaps recurse into all children. We can't do this any more
without passing has_gaps, gaps_inner and gaps_outer as arguments to
arrange_children, so I've changed the add_gaps function to retrieve it
from the workspace directly.
apply_tabbed_or_stacked_layout has been split into two functions, as it
had different logic depending on the layout.
Lastly, arrange.h had an unnecessary include of transaction.h. I've
removed it, which means I've had to add it to several other files.
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 list includes disabled outputs.
When sway_container is demoted, we'll need to store the root's children
(ie. enabled outputs) in the sway_root. It makes sense to put these in a
list called `outputs`, so I'm renaming the existing list in advance.
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.
Previously we used a reparent event to detect when a view changes
parent, then sent an output enter/leave to the surfaces if needed. This
worked for tiling views but not floating views, as floating views can
intersect another output without changing parent.
The solution implemented for floating views also applies cleanly to
tiling views, so the previous method has been completely replaced and
the reparent event has been removed.
This introduces a new function container_discover_outputs. This function
compares the container's `current` position to the outputs, sends enter
and leave events as needed, and keeps track of which outputs it's
intersecting in a new `container->outputs` list. If it has entered a new
output with a different scale then the title and marks textures will
also be recreated at the new scale.
The function is called when a transaction applies. This is convenient as
it means we don't have to call it from various places.
There is imperfect rendering when a floating view overlaps two outputs
with different scales. It renders correctly for the most recently
entered output, but there is only one title texture so it renders
incorrectly on the old output.
Fixes#2482
We were removing the saved buffer when one transaction applies, then
didn't have a new buffer to save when the next transaction ran. This
made the rendering code crash as it had no surface to use.
This commit makes it continue to hold the buffer if the view is
destroying and has more transactions. Additionally, a check is added
when saving the buffer to make sure there's no one already there.
