This reenables the popup-handling code before the floating-window focus change.
2018-10-03Use "raycasting" for determining focus for floating windowsJonathan Buch
Floating containers and their surfaces are ordered in "raised last". This is used to detect the topmost surface and thus the focus.
2018-10-03Fix focusing topmost floating windowsJonathan Buch
Re-focus on the container on which the cursor hovers over. A special case is, if there are menus or other subsurfaces open in the focused container. It will prefer the focused container as long as there are subsurfaces. This commit starts caching the previous node as well as the previous x/y cursor position. Re-calculating the previous focused node by looking at the current state of the cursor position does not work, if the environment changes.

Add CSD to border modes
2018-10-01Handle border options for gapsBrian Ashworth
Fixes `hide_edge_borders smart` when gaps are in use. Implements `hide_edge_borders smart_no_gaps` and `smart_borders on|no_gaps|off`. Since `smart_borders on` is equivalent to `hide_edge_borders smart` and `smart_borders no_gaps` is equivalent to `hide_edge_borders smart_no_gaps`, I opted to just save the last value set for `hide_edge_borders` and restore that on `smart_borders off`. This simplifies the conditions for setting the border.

2018-09-30Fix hotplugging down to zero outputsRyan Dwyer
When the last output is disconnected, output_disable is called like usual and evacuates the output to the root->saved_workspaces list. It then calls root_for_each_container to remove (untrack) the output from each container's outputs list. However root_for_each_container did not iterate the saved workspaces, so when the output gets freed the containers would have a dangling pointer in their outputs list. Upon reconnect, container_discover_outputs would attempt to use the dangling pointer, causing a crash. This makes root_for_each_container check the saved workspaces list, which fixes the problem.

2018-09-29Make gaps implementation consistent with i3-gapsRyan Dwyer
This changes our gaps implementation to behave like i3-gaps. Our previous implementation allowed you to set gaps on a per container basis. This isn't supported by i3-gaps and doesn't seem to have a practical use case. The gaps_outer and gaps_inner properties on containers are now removed as they just read the gaps_inner from the workspace. `gaps inner|outer <px>` no longer changes the gaps for all workspaces. It only sets defaults for new workspaces. `gaps inner|outer current|workspace|all set|plus|minus <px>` is now runtime only, and the workspace option is now removed. `current` now sets gaps for the current workspace as opposed to the current container. `workspace <ws> gaps inner|outer <px>` is now implemented. This sets defaults for a workspace. This also fixes a bug where changing the layout of a split container from linear to tabbed would cause gaps to not be applied to it until you switch to another workspace and back.

2018-09-28Rename workspace_outputs to workspace_configs and fix memory leakRyan Dwyer
When we eventually implement `workspace <ws> gaps inner|outer <px>`, we'll need to store the gaps settings for workspaces before they're created. Rather than create a workspace_gaps struct, the approach I'm taking is to rename workspace_outputs to workspace_configs and then add gaps settings to that. I've added a lookup function workspace_find_config. Note that we have a similar thing for outputs (output_config struct and output_find_config). Lastly, when freeing config it would create a memory leak by freeing the list items but not the workspace or output names inside them. This has been rectified using a free_workspace_config function.
2018-09-28Fix floating views in tabbed/stacked workspaces not getting frame eventsRyan Dwyer
view_is_visible would return false, which meant the view wouldn't receive a frame done event. view_is_visible needs to make an exception for floating containers. This also moves the workspace_is_visible check to an earlier location for performance reasons.
2018-09-27Improve CSD logicRyan Dwyer
This does the following: * Removes the xdg-decoration surface_commit listener. I was under the impression the client could ignore the server's preference and set whatever decoration they like using this protocol, but I don't think that's right. * Adds a listener for the xdg-decoration request_mode signal. The protocol states that the server should respond to this with its preference. We'll always respond with SSD here. * Makes it so tiled views which use CSD will still have sway decorations rendered. To do this, using_csd had to be added back to the view struct, and the border is changed when floating or unfloating a view.
2018-09-27Rename view_set_csd_from_client to view_update_csd_from_clientRyan Dwyer
2018-09-27Add CSD to border modesRyan Dwyer
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.
2018-09-26Fix race condition crash when view unmaps + maps quicklyRyan Dwyer
When a view unmaps, we start a transaction to destroy the container, then when the transaction completes we destroy the container and unset the view's container pointer. But if the view has remapped in the meantime, the view's container pointer will be pointing to a different container which should not be cleared. This adds a check to make sure the view is still pointing to the container being destroyed before clearing the pointer. The freeing of the title format is also removed as it is already freed when the view destroys in view_destroy.
2018-09-25Fix crash when disconnecting outputRyan Dwyer
If the output being disconnected contains views, and the views are being relocated to another output of a different size, a transaction must occur to reconfigure them. This means by the time container_discover_outputs is called, the output is already disabled and wlr_output is NULL. I considered making it check output->wlr_output, but output->enabled should work just as well and is more descriptive.

2018-09-23Prevent sticky containers from jumping on workspace switchRyan Dwyer
If you have swaybar docked to the top, and you create a floating sticky container and switch workspaces on the same output, the sticky container would move down by the height of swaybar on each switch. This happens because when creating the workspace we set the dimensions to the same as the output, then the subsequent arrange corrects it. During this arrange, floating containers are translated so they stay relative to the workspace. This translation needs to not occur for the initial arrange. This patch makes workspaces have a zero width and height when first created, so we can detect whether this is the initial arrange and avoid translating the floating containers if so.

Allow running commands on containers without focusing them
2018-09-23Allow running commands on containers without focusing themRyan Dwyer
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.

Fix double iteration of scratchpad containers
2018-09-22Fix pango escaping and refactor escape_markup_textRyan Dwyer
Fixes #2674. The cause of the issue was in get_pango_layout. When we call pango_parse_markup, `text` is the escaped string, and the unescaped string is then computed and written to `buf`. We were then passing the unescaped string to pango_layout_set_markup, but this function needs the escaped string. `buf` is not needed and has been removed. The other part of this PR refactors escape_markup_text to remove the dest_length argument and removes the -1 return value on error. It now assumes that you've allocated dest to the correct length.
2018-09-22Implement tab cycling using mouse wheelRyan Dwyer
Firstly, a change had to be made to the container_at functions. If you create layout `T[view H[view view]]` and hover the second tab, the container_at functions would return the focus_inactive child. They now return the split container itself. To compensate for this, dispatch_cursor_button has been adjusted to find the focus_inactive child before focusing it. The actual implementation of wheel scrolling is pretty straightforward. This uses handle_cursor_axis, so I took a similar approach to handle_cursor_button (ie. creating a dispatch_cursor_axis function).

2018-09-18Fix double iteration of scratchpad containersRyan Dwyer
root_for_each_container and root_find_container were using incorrect logic to determine if a container was hidden in the scratchpad. Containers will have a NULL parent if they are a direct child of a workspace. Containers will have a NULL workspace if they are hidden in the scratchpad. The incorrect check meant that root_for_each_container would run the callback on scratchpad containers twice. This meant that executing a command such as `[class="$something"] scratchpad show` would cause the command to run twice, resulting in the container being shown and hidden again which is effectively a no op. Fixes #2655.

2018-09-16Fix crash when unmapping last child of a tabbed workspaceRyan Dwyer
* Create layout T[view view] * Move the cursor into the title bar area * Close both views Sway would crash because container_at_tabbed would attempt to divide by zero when there are no children. The children check isn't needed for the stacked function because it doesn't divide anything by the number of children. Fixes #2636.

2018-09-11Fix crash in workspace_wrap_childrenRyan Dwyer
When workspace_wrap_children is called on a workspace which has a fullscreen child and the fullscreen child is a direct child of the workspace, sway would crash. The workspace's fullscreen pointer is unset when the fullscreen container is detached and applied again when added to a parent, but in this case the parent hadn't yet been added to the workspace which meant con->workspace was NULL. The fix makes container_handle_fullscreen_reparent return if there's no workspace, and the fullscreen pointer is reapplied in workspace_wrap_children.

2018-09-08Align titles to baselineRyan Dwyer
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.
2018-09-06Second attempt at restoring focus when closing a fullscreen viewRyan Dwyer
To reproduce the problem this is fixing, create H[view view view], fullscreen one of the views and close it. The entire workspace will be given focus rather than one of the siblings. This happens because we emit the destroy event, so the seat code tries to find a new focus, but the view it finds is still believed to be hidden by the fullscreen view so it's discarded and the workspace is used instead. This clears the workspace's fullscreen pointer prior to emitting the destroy event so that the seat code finds an appropriate new focus.
