Function Documentation

_wlmim_cursor_handle_axis()

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

static

Handler for the axis event of wlr_cursor.

Parameters

listener_ptr
data_ptr	Points to a wlr_pointer_axis_event.

_wlmim_cursor_handle_button()

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

static

Handler for the button event of wlr_cursor.

Parameters

listener_ptr
data_ptr	Points to a wlr_pointer_button_event.

_wlmim_cursor_handle_frame()

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

static

Handler for the frame event of wlr_cursor.

Parameters

listener_ptr
data_ptr

_wlmim_cursor_handle_motion()

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

static

Handler for the motion event of wlr_cursor.

Parameters

listener_ptr
data_ptr	Points to a wlr_pointer_motion_event.

_wlmim_cursor_handle_motion_absolute()

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

static

Handler for the motion_absolute event of wlr_cursor.

Parameters

listener_ptr
data_ptr	Points to a wlr_pointer_motion_absolute_event.

_wlmim_cursor_handle_seat_request_set_cursor()

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

static

Handler for the request_set_cursor event of wlr_seat.

This event is raised when a client provides a cursor image. It is accepted only if the client also has the pointer focus.

Parameters

listener_ptr
data_ptr	Points to a wlr_seat_pointer_request_set_cursor_event.

_wlmim_cursor_process_motion()

void _wlmim_cursor_process_motion ( wlmim_cursor_t *  cursor_ptr, uint32_t  time_msec  )

static

Processes the cursor motion: Lookups up the view & surface under the pointer and sets (respectively: clears) the pointer focus. Also sets the default cursor image, if no view is given (== no client-side cursor).

Parameters

cursor_ptr
time_msec

wlmim_cursor_attach_input_device()

void wlmim_cursor_attach_input_device	(	wlmim_cursor_t *	cursor_ptr,
		struct wlr_input_device *	wlr_input_device_ptr
	)

Attaches the input device. May be a pointer, touch or tablet_tool device.

Parameters

cursor_ptr
wlr_input_device_ptr

wlmim_cursor_create()

wlmim_cursor_t * wlmim_cursor_create	(	wlmim_t *	input_manager_ptr,
		const struct wlmim_cursor_style *	style_ptr,
		struct wlr_output_layout *	wlr_output_layout_ptr,
		struct wlr_seat *	wlr_seat_ptr,
		wlmtk_root_t *	root_ptr
	)

Creates the cursor handlers.

Parameters

input_manager_ptr
style_ptr
wlr_output_layout_ptr
wlr_seat_ptr
root_ptr

Returns

The cursor handler or NULL on error.

wlmim_cursor_destroy()

void wlmim_cursor_destroy

(

wlmim_cursor_t *

cursor_ptr

)

Destroys the cursor handlers.

Parameters

cursor_ptr

wlmim_cursor_detach_input_device()

void wlmim_cursor_detach_input_device	(	wlmim_cursor_t *	cursor_ptr,
		struct wlr_input_device *	wlr_input_device_ptr
	)

Detaches the input device.

See also

wlmim_cursor_attach_input_device.

Parameters

cursor_ptr
wlr_input_device_ptr

wlmim_cursor_wlr_cursor()

struct wlr_cursor * wlmim_cursor_wlr_cursor

(

wlmim_cursor_t *

cursor_ptr

)

Returns

wlmim_cursor_t::wlr_cursor_ptr.
