Here is the call graph for this function:

◆ get_first_output()

Output* get_first_output ( void )

Returns the first output which is active.

Definition at line 72 of file randr.c.

References xoutput::active, die, outputs, and TAILQ_FOREACH.

Referenced by main(), and randr_disable_output().

◆ get_output_by_name()

Output* get_output_by_name	(	const char *	name,
		const bool	require_active
	)

Returns the output with the given name or NULL.

If require_active is true, only active outputs are considered.

Definition at line 47 of file randr.c.

References xoutput::active, output_name::name, output_name::names, xoutput::names_head, outputs, xoutput::primary, SLIST_FOREACH, and TAILQ_FOREACH.

Referenced by canonicalize_output_name(), get_output_for_con(), get_output_from_string(), init_ws_for_output(), and randr_query_outputs_15().

◆ get_output_containing()

Output* get_output_containing	(	unsigned int	x,
		unsigned int	y
	)

Returns the active (!) output which contains the coordinates x, y or NULL if there is no output which contains these coordinates.

Definition at line 102 of file randr.c.

References xoutput::active, DLOG, Rect::height, outputs, xoutput::rect, TAILQ_FOREACH, Rect::width, Rect::x, and Rect::y.

Referenced by _tree_next(), check_crossing_screen_boundary(), floating_enable(), floating_maybe_reassign_ws(), floating_move_to_pointer(), handle_configure_request(), main(), manage_window(), and x_push_changes().

◆ get_output_next()

Output* get_output_next	(	direction_t	direction,
		Output *	current,
		output_close_far_t	close_far
	)

Gets the output which is the next one in the given direction.

If close_far == CLOSEST_OUTPUT, then the output next to the current one will selected. If close_far == FARTHEST_OUTPUT, the output which is the last one in the given direction will be selected.

NULL will be returned when no active outputs are present in the direction specified (note that ‘current’ counts as such an output).

Definition at line 204 of file randr.c.

References xoutput::active, CLOSEST_OUTPUT, D_DOWN, D_LEFT, D_RIGHT, D_UP, DLOG, Rect::height, output_primary_name(), outputs, xoutput::rect, TAILQ_FOREACH, Rect::width, Rect::x, and Rect::y.

Referenced by _tree_next(), get_output_next_wrap(), and move_to_output_directed().

Here is the call graph for this function:

◆ get_output_next_wrap()

Output* get_output_next_wrap	(	direction_t	direction,
		Output *	current
	)

Like get_output_next with close_far == CLOSEST_OUTPUT, but wraps.

For example if get_output_next(D_DOWN, x, FARTHEST_OUTPUT) = NULL, then get_output_next_wrap(D_DOWN, x) will return the topmost output.

This function always returns a output: if no active outputs can be found, current itself is returned.

◆ get_output_with_dimensions()

Output* get_output_with_dimensions ( Rect rect )

Returns the active output which spans exactly the area specified by rect or NULL if there is no output like this.

Definition at line 122 of file randr.c.

References xoutput::active, DLOG, Rect::height, outputs, xoutput::rect, TAILQ_FOREACH, Rect::width, Rect::x, and Rect::y.

Referenced by manage_window().

◆ init_ws_for_output()

void init_ws_for_output	(	Output *	output,
		Con *	content
	)

Initializes at least one workspace for this output, trying the following steps until there is at least one workspace:

• Move existing workspaces, which are assigned to be on the given output, to the output. • Create the first assigned workspace for this output. • Create the first unused workspace.
