Function Documentation

_wlmaker_corner_clear()

void _wlmaker_corner_clear ( wlmaker_corner_t *  corner_ptr )

static

Clears the hot-corner tracking and activation.

_wlmaker_corner_evaluate()

void _wlmaker_corner_evaluate ( wlmaker_corner_t *  corner_ptr )

static

(Re)evaluates hot corner state from layout extents and pointer position.

_wlmaker_corner_handle_output_layout_changed()

void _wlmaker_corner_handle_output_layout_changed ( struct wl_listener *  listener_ptr, void *  data_ptr  )

static

Handles change events of struct wlr_output_layout.

Will recompute the output's layout settings and re-evaluate the current cursor position.

Parameters

listener_ptr
data_ptr	Points to a struct wlr_output_layout.

_wlmaker_corner_handle_position_updated()

void _wlmaker_corner_handle_position_updated ( struct wl_listener *  listener_ptr, void *  data_ptr  )

static

Handles wlmaker_cursor_t::position_updated signal callbacks.

Stores the pointer's position in wlmaker_corner_t. If the position is different than before, triggers a re-evaluation of whether a corner is occupied.

Parameters

listener_ptr
data_ptr	Points to a struct wlr_cursor.

_wlmaker_corner_handle_timer()

int _wlmaker_corner_handle_timer ( void *  data_ptr )

static

Handles timer callbacks: Sends 'enter' event and registers triggering.

_wlmaker_corner_occupy()

void _wlmaker_corner_occupy ( wlmaker_corner_t *  corner_ptr, unsigned  position  )

static

Starts occupation of a corner.

Parameters

corner_ptr
position

_wlmaker_corner_test()

void _wlmaker_corner_test ( bs_test_t *  test_ptr )

static

Exercises the hot corner module.

_wlmaker_corner_update_layout()

void _wlmaker_corner_update_layout ( wlmaker_corner_t *  corner_ptr, struct wlr_box *  extents_ptr  )

static

Updates the output extents. Triggers a re-evaluation.

wlmaker_corner_create()

wlmaker_corner_t * wlmaker_corner_create	(	bspl_dict_t *	hot_corner_config_dict_ptr,
		struct wl_event_loop *	wl_event_loop_ptr,
		struct wlr_output_layout *	wlr_output_layout_ptr,
		wlmaker_cursor_t *	cursor_ptr,
		wlmaker_server_t *	server_ptr
	)

Creates the hot-corner handler.

Parameters

hot_corner_config_dict_ptr
wl_event_loop_ptr
wlr_output_layout_ptr
cursor_ptr
server_ptr

Returns

Pointer to the hot-corner monitor.

wlmaker_corner_destroy()

void wlmaker_corner_destroy

(

wlmaker_corner_t *

corner_ptr

)

Destroys the hot-corner handler.

Parameters

corner_ptr

Variable Documentation

_wlmaker_corner_config_desc

const bspl_desc_t _wlmaker_corner_config_desc[]

static

Descriptor for the 'HotConfig' config dictionary.

wlmaker_corner_test_cases

const bs_test_case_t wlmaker_corner_test_cases[]

Initial value:

= {
    { 1, "test", _wlmaker_corner_test },
    { 0, NULL, NULL }
}

Unit test cases.
