Function Documentation

_wlclient_icon_input_position_observer_position()

void _wlclient_icon_input_position_observer_position ( void * data_ptr, struct ext_input_position_observer_v1 * input_position_observer_ptr, struct wl_surface * wl_surface_ptr, uint32_t instance, int32_t relative_x, int32_t relative_y )

static

Callback for when a position event is received.

handle_toplevel_icon_configure()

void handle_toplevel_icon_configure ( void * data_ptr, struct zwlmaker_toplevel_icon_v1 * zwlmaker_toplevel_icon_v1_ptr, int32_t width, int32_t height, uint32_t serial )

static

Handles the 'configure' event: Creates appropriately sized buffer.

Parameters

wlclient_icon_create()

wlclient_icon_t * wlclient_icon_create

(

wlclient_t *

wlclient_ptr

)

Creates an icon.

Parameters

wlclient_ptr

Returns

An icon state or NULL on error. The state must be free'd by calling wlclient_icon_destroy.

wlclient_icon_destroy()

void wlclient_icon_destroy

(

wlclient_icon_t *

icon_ptr

)

Destroys the icon.

Parameters

icon_ptr

wlclient_icon_register_position_callback()

void wlclient_icon_register_position_callback	(	wlclient_icon_t *	icon_ptr,
		void(*	callback )(double x, double y, void *ud_ptr),
		void *	callback_ud_ptr )

Registers the callback to notify the pointer position relative to the icon's surface.

Parameters

icon_ptr
callback
callback_ud_ptr

wlclient_icon_register_ready_callback()

void wlclient_icon_register_ready_callback	(	wlclient_icon_t *	icon_ptr,
		bool(*	callback )(bs_gfxbuf_t *gfxbuf_ptr, void *ud_ptr),
		void *	ud_ptr )

Sets a callback to invoke when the background buffer is ready for drawing.

See also

wlcl_dblbuf_register_ready_callback.

Parameters

icon_ptr
callback
ud_ptr

wlclient_icon_supported()

bool wlclient_icon_supported

(

wlclient_t *

wlclient_ptr

)

Returns whether the icon protocol is supported on the client.

Parameters

wlclient_ptr
