Function Documentation

bool level_down ( void )

Moves focus one level down.

Returns true if focus changed.

Definition at line 476 of file tree.c.

References con_focus(), DLOG, TAILQ_END, TAILQ_FIRST, and Con::type.

bool level_up ( void )

Moves focus one level up.

Returns true if focus changed.

Definition at line 453 of file tree.c.

Here is the call graph for this function:

TAILQ_HEAD	(	all_cons_head	,
		Con
	)

bool tree_close	(	Con *	con,
		kill_window_t	kill_window,
		bool	dont_kill_parent,
		bool	force_set_focus
	)

Closes the given container including all children.

Returns true if the container was killed or false if just WM_DELETE was sent and the window is expected to kill itself.

The dont_kill_parent flag is specified when the function calls itself recursively while deleting a containers children.

The force_set_focus flag is specified in the case of killing a floating window: tree_close() will be invoked for the CT_FLOATINGCON (the parent container) and focus should be set there.

void tree_flatten ( Con * child )

tree_flatten() removes pairs of redundant split containers, e.g.

: [workspace, horizontal] [v-split] [child3] [h-split] [child1] [child2] In this example, the v-split and h-split container are redundant. Such a situation can be created by moving containers in a direction which is not the orientation of their parent container. i3 needs to create a new split container then and if you move containers this way multiple times, redundant chains of split-containers can be the result.
