Function Documentation

void center_pointer

(

xcb_rectangle_t

rect

)

void check_other_wm

(

void

)

Try to detect if another WM exists.

If another WM exists (this can be seen by whether it has registered itself with the X11 server) then howm will exit.

void delete_win

(

xcb_window_t

win

)

Ask XCB to delete a window.

Parameters

win	The window to be deleted.

void elevate_window

(

xcb_window_t

win

)

Move a window to the front of all the other windows.

Parameters

win	The window to be moved.

void ewmh_process_wm_state	(	client_t *	c,
		xcb_atom_t	a,
		int	action
	)

Handle client messages that are related to WM_STATE.

TODO: Add more WM_STATE hints.

Parameters

c	The client that is to have its WM_STATE modified.
a	The atom representing which WM_STATE hint should be modified.
action	Whether to remove, add or toggle the WM_STATE hint.

void ewmh_set_current_workspace

(

void

)

void focus_window

(

xcb_window_t

win

)

Focus the given window, so long as it isn't already focused.

Parameters

win	A window that belongs to a client being managed by howm.

void get_atoms	(	const char **	names,
		xcb_atom_t *	atoms
	)

Request all of the atoms that howm supports.

Parameters

names	The names of the atoms to be fetched.
atoms	Where the returned atoms will be stored.

void grab_buttons

(

client_t *

c

)

Make a client listen for button press events.

Parameters

c	The client that needs to listen for button presses.

void move_resize	(	xcb_window_t	win,
		uint16_t	x,
		uint16_t	y,
		uint16_t	w,
		uint16_t	h
	)

Change the dimensions and location of a window (win).

Parameters

win	The window upon which the operations should be performed.
x	The new x location of the top left corner.
y	The new y location of the top left corner.
w	The new width of the window.
h	The new height of the window.

xcb_rectangle_t output_reply_to_rect

(

xcb_randr_get_output_info_reply_t *

output

)

xcb_randr_output_t* randr_get_outputs

(

unsigned int *

nr_outputs

)

xcb_randr_output_t randr_get_primary_output

(

void

)

void set_border_width	(	xcb_window_t	win,
		uint16_t	w
	)

Sets the width of the borders around a window (win).

Parameters

win	The window that will have its border width changed.
w	The new width of the window's border.

void setup_ewmh

(

void

)

Create the EWMH connection, request all of the atoms and set some sensible defaults for them.

void setup_ewmh_geom

(

void

)

void warp_pointer	(	int16_t	x,
		int16_t	y
	)
