239 * Clear the container's focus stack and re-add it using the provided container

242 * in the new focus stack if container is not a workspace.

248 * Returns the number of children of this container.
251 int con_num_children(Con *con);
254 * Returns the number of visible non-floating children of this container.
255 * For example, if the container contains a hsplit which has two children,
256 * this will return 2 instead of 1.

261 * Count the number of windows (i.e., leaf containers).

267 * Attaches the given container to the given parent. This happens when moving
268 * a container or when inserting a new container at a specific place in the
271 * ignore_focus is to just insert the Con at the end (useful when creating a
272 * new split container *around* some containers, that is, detaching and

279 * Detaches the given container from its current parent
282 void con_detach(Con *con);
285 * Updates the percent attribute of the children of the given container. This
286 * function needs to be called when a window is added or removed from a

315 * The fix_coordinates flag will translate the current coordinates (offset from
316 * the monitor position basically) to appropriate coordinates on the
317 * destination workspace.
318 * Not enabling this behaviour comes in handy when this function gets called by
319 * floating_maybe_reassign_ws, which will only "move" a floating window when it
320 * *already* changed its coordinates to a different output.
322 * The dont_warp flag disables pointer warping and will be set when this
323 * function is called while dragging a floating window.
325 * If ignore_focus is set, the container will be moved without modifying focus
328 * TODO: is there a better place for this function?
331 void con_move_to_workspace(Con *con, Con *workspace, bool fix_coordinates,

335 * Moves the given container to the currently focused container on the
336 * visible workspace on the given output.
339 void con_move_to_output(Con *con, Output *output, bool fix_coordinates);
342 * Moves the given container to the currently focused container on the
343 * visible workspace on the output specified by the given name.
344 * The current output for the container is used to resolve relative names
345 * such as left, right, up, down.

351 * Moves the given container to the given mark.

358 * vertical orientation is used regardless of the actual orientation of the
362 orientation_t con_orientation(Con *con);
365 * Returns the container which will be focused next when the given container
366 * is not available anymore. Called in tree_close_internal and con_move_to_workspace
367 * to properly restore focus.
370 Con *con_next_focused(Con *con);
373 * Get the next/previous container in the specified orientation. This may
374 * travel up until it finds a container with suitable orientation.
377 Con *con_get_next(Con *con, char way, orientation_t orientation);
380 * Returns the focused con inside this client, descending the tree as far as
381 * possible. This comes in handy when attaching a con to a workspace at the
382 * currently focused position, for example.
385 Con *con_descend_focused(Con *con);
388 * Returns the focused con inside this client, descending the tree as far as
389 * possible. This comes in handy when attaching a con to a workspace at the
390 * currently focused position, for example.
392 * Works like con_descend_focused but considers only tiling cons.
395 Con *con_descend_tiling_focused(Con *con);
398 * Returns the leftmost, rightmost, etc. container in sub-tree. For example, if
399 * direction is D_LEFT, then we return the rightmost container and if direction
400 * is D_RIGHT, we return the leftmost container. This is because if we are
401 * moving D_LEFT, and thus want the rightmost container.
403 Con *con_descend_direction(Con *con, direction_t direction);
406 * Returns a "relative" Rect which contains the amount of pixels that need to
407 * be added to the original Rect to get the final position (obviously the
408 * amount of pixels for normal, 1pixel and borderless are different).
411 Rect con_border_style_rect(Con *con);
414 * Returns adjacent borders of the window. We need this if hide_edge_borders is
417 adjacent_t con_adjacent_borders(Con *con);
420 * Use this function to get a container’s border style. This is important
421 * because when inside a stack, the border style is always BS_NORMAL.
422 * For tabbed mode, the same applies, with one exception: when the container is
423 * borderless and the only element in the tabbed container, the border is not
426 * For children of a CT_DOCKAREA, the border style is always none.
429 int con_border_style(Con *con);
432 * Sets the given border style on con, correctly keeping the position/size of a
436 void con_set_border_style(Con *con, int border_style, int border_width);
439 * This function changes the layout of a given container. Use it to handle
440 * special cases like changing a whole workspace to stacked/tabbed (creates a
441 * new split container before).
444 void con_set_layout(Con *con, layout_t layout);
447 * This function toggles the layout of a given container. toggle_mode can be
448 * either 'default' (toggle only between stacked/tabbed/last_split_layout),
449 * 'split' (toggle only between splitv/splith) or 'all' (toggle between all
453 void con_toggle_layout(Con *con, const char *toggle_mode);
456 * Determines the minimum size of the given con by looking at its children (for
457 * split/stacked/tabbed cons). Will be called when resizing floating cons
460 Rect con_minimum_size(Con *con);
463 * Returns true if changing the focus to con would be allowed considering
464 * the fullscreen focus constraints. Specifically, if a fullscreen container or
465 * any of its descendants is focused, this function returns true if and only if
466 * focusing con would mean that focus would still be visible on screen, i.e.,
467 * the newly focused container would not be obscured by a fullscreen container.
469 * In the simplest case, if a fullscreen container or any of its descendants is
470 * fullscreen, this functions returns true if con is the fullscreen container
471 * itself or any of its descendants, as this means focus wouldn't escape the
472 * boundaries of the fullscreen container.
474 * In case the fullscreen container is of type CF_OUTPUT, this function returns
475 * true if con is on a different workspace, as focus wouldn't be obscured by
476 * the fullscreen container that is constrained to a different workspace.
478 * Note that this same logic can be applied to moving containers. If a
479 * container can be focused under the fullscreen focus constraints, it can also
480 * become a parent or sibling to the currently focused container.
483 bool con_fullscreen_permits_focusing(Con *con);
486 * Checks if the given container has an urgent child.
489 bool con_has_urgent_child(Con *con);
492 * Make all parent containers urgent if con is urgent or clear the urgent flag
493 * of all parent containers if there are no more urgent children left.
496 void con_update_parents_urgency(Con *con);
499 * Set urgency flag to the container, all the parent containers and the workspace.
502 void con_set_urgency(Con *con, bool urgent);
505 * Create a string representing the subtree under con.
508 char *con_get_tree_representation(Con *con);
511 * force parent split containers to be redrawn
514 void con_force_split_parents_redraw(Con *con);
517 * Returns the window title considering the current title format.
520 i3String *con_parse_title_format(Con *con);
523 * Swaps the two containers.
526 bool con_swap(Con *first, Con *second);
