Here is the call graph for this function:

Output* get_first_output ( void )

Returns the first output which is active.

Definition at line 66 of file randr.c.

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

Referenced by main(), and randr_query_outputs().

Output* get_output_by_name ( const char * name )

Returns the output with the given name if it is active (!) or NULL.

Referenced by get_output_from_string(), get_output_of_con(), init_ws_for_output(), move_to_output_directed(), and workspace_move_to_output().

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.

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).

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

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.

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.
