43 bool con_has_managed_window(Con *con);
46 * Returns true if a container should be considered split.
49 bool con_is_split(Con *con);

62 bool con_is_sticky(Con *con);
65 * Returns true if this node has regular or floating children.
68 bool con_has_children(Con *con);
71 * Returns true if this node accepts a window (if the node swallows windows,
72 * it might already have swallowed enough and cannot hold any more).

78 * Gets the output container (first container with CT_OUTPUT in hierarchy) this
82 Con *con_get_output(Con *con);
85 * Gets the workspace container this node is on.

120 Con *con_inside_floating(Con *con);
123 * Checks if the given container is inside a focused container.

156 * Toggles the mark on a container.

190 * Attaches the given container to the given parent. This happens when moving
191 * a container or when inserting a new container at a specific place in the
194 * ignore_focus is to just insert the Con at the end (useful when creating a
195 * new split container *around* some containers, that is, detaching and
196 * attaching them in order without wanting to mess with the focus in between).
199 void con_attach(Con *con, Con *parent, bool ignore_focus);
202 * Detaches the given container from its current parent
205 void con_detach(Con *con);
208 * Updates the percent attribute of the children of the given container. This
209 * function needs to be called when a window is added or removed from a
213 void con_fix_percent(Con *con);
216 * Toggles fullscreen mode for the given container. Fullscreen mode will not be
217 * entered when there already is a fullscreen container on this workspace.

223 * Enables fullscreen mode for the given container, if necessary.

235 * Moves the given container to the currently focused container on the given
238 * The fix_coordinates flag will translate the current coordinates (offset from
239 * the monitor position basically) to appropriate coordinates on the
240 * destination workspace.
241 * Not enabling this behaviour comes in handy when this function gets called by
242 * floating_maybe_reassign_ws, which will only "move" a floating window when it
243 * *already* changed its coordinates to a different output.
245 * The dont_warp flag disables pointer warping and will be set when this
246 * function is called while dragging a floating window.
248 * If ignore_focus is set, the container will be moved without modifying focus
251 * TODO: is there a better place for this function?
254 void con_move_to_workspace(Con *con, Con *workspace, bool fix_coordinates,
255 bool dont_warp, bool ignore_focus);
258 * Moves the given container to the given mark.
261 bool con_move_to_mark(Con *con, const char *mark);
264 * Returns the orientation of the given container (for stacked containers,
265 * vertical orientation is used regardless of the actual orientation of the
269 orientation_t con_orientation(Con *con);
272 * Returns the container which will be focused next when the given container
273 * is not available anymore. Called in tree_close and con_move_to_workspace
274 * to properly restore focus.
277 Con *con_next_focused(Con *con);
280 * Get the next/previous container in the specified orientation. This may
281 * travel up until it finds a container with suitable orientation.
284 Con *con_get_next(Con *con, char way, orientation_t orientation);
287 * Returns the focused con inside this client, descending the tree as far as
288 * possible. This comes in handy when attaching a con to a workspace at the
289 * currently focused position, for example.
292 Con *con_descend_focused(Con *con);
295 * Returns the focused con inside this client, descending the tree as far as
296 * possible. This comes in handy when attaching a con to a workspace at the
297 * currently focused position, for example.
299 * Works like con_descend_focused but considers only tiling cons.
302 Con *con_descend_tiling_focused(Con *con);
305 * Returns the leftmost, rightmost, etc. container in sub-tree. For example, if
306 * direction is D_LEFT, then we return the rightmost container and if direction
307 * is D_RIGHT, we return the leftmost container. This is because if we are
308 * moving D_LEFT, and thus want the rightmost container.
310 Con *con_descend_direction(Con *con, direction_t direction);
313 * Returns a "relative" Rect which contains the amount of pixels that need to
314 * be added to the original Rect to get the final position (obviously the
315 * amount of pixels for normal, 1pixel and borderless are different).
318 Rect con_border_style_rect(Con *con);
321 * Returns adjacent borders of the window. We need this if hide_edge_borders is
324 adjacent_t con_adjacent_borders(Con *con);
327 * Use this function to get a container’s border style. This is important
328 * because when inside a stack, the border style is always BS_NORMAL.
329 * For tabbed mode, the same applies, with one exception: when the container is
330 * borderless and the only element in the tabbed container, the border is not
333 * For children of a CT_DOCKAREA, the border style is always none.
336 int con_border_style(Con *con);
339 * Sets the given border style on con, correctly keeping the position/size of a
343 void con_set_border_style(Con *con, int border_style, int border_width);
346 * This function changes the layout of a given container. Use it to handle
347 * special cases like changing a whole workspace to stacked/tabbed (creates a
348 * new split container before).
351 void con_set_layout(Con *con, layout_t layout);
354 * This function toggles the layout of a given container. toggle_mode can be
355 * either 'default' (toggle only between stacked/tabbed/last_split_layout),
356 * 'split' (toggle only between splitv/splith) or 'all' (toggle between all
360 void con_toggle_layout(Con *con, const char *toggle_mode);
363 * Determines the minimum size of the given con by looking at its children (for
364 * split/stacked/tabbed cons). Will be called when resizing floating cons
367 Rect con_minimum_size(Con *con);
370 * Returns true if changing the focus to con would be allowed considering
371 * the fullscreen focus constraints. Specifically, if a fullscreen container or
372 * any of its descendants is focused, this function returns true if and only if
373 * focusing con would mean that focus would still be visible on screen, i.e.,
374 * the newly focused container would not be obscured by a fullscreen container.
376 * In the simplest case, if a fullscreen container or any of its descendants is
377 * fullscreen, this functions returns true if con is the fullscreen container
378 * itself or any of its descendants, as this means focus wouldn't escape the
379 * boundaries of the fullscreen container.
381 * In case the fullscreen container is of type CF_OUTPUT, this function returns
382 * true if con is on a different workspace, as focus wouldn't be obscured by
383 * the fullscreen container that is constrained to a different workspace.
385 * Note that this same logic can be applied to moving containers. If a
386 * container can be focused under the fullscreen focus constraints, it can also
387 * become a parent or sibling to the currently focused container.
390 bool con_fullscreen_permits_focusing(Con *con);
393 * Checks if the given container has an urgent child.
396 bool con_has_urgent_child(Con *con);
399 * Make all parent containers urgent if con is urgent or clear the urgent flag
400 * of all parent containers if there are no more urgent children left.
403 void con_update_parents_urgency(Con *con);
406 * Set urgency flag to the container, all the parent containers and the workspace.
409 void con_set_urgency(Con *con, bool urgent);
412 * Create a string representing the subtree under con.
415 char *con_get_tree_representation(Con *con);
418 * force parent split containers to be redrawn
421 void con_force_split_parents_redraw(Con *con);
