Function Documentation

_wlmtk_rectangle_element_create_scene_node()

struct wlr_scene_node * _wlmtk_rectangle_element_create_scene_node ( wlmtk_element_t *  element_ptr, struct wlr_scene_tree *  wlr_scene_tree_ptr  )

static

Implementation of the superclass wlmtk_element_t::create_scene_node method.

Creates a struct wlr_scene_rect attached to wlr_scene_tree_ptr.

Parameters

element_ptr
wlr_scene_tree_ptr

_wlmtk_rectangle_element_destroy()

void _wlmtk_rectangle_element_destroy ( wlmtk_element_t *  element_ptr )

static

Virtual dtor: Invoke the rectangle's dtor.

_wlmtk_rectangle_element_pointer_motion()

bool _wlmtk_rectangle_element_pointer_motion ( wlmtk_element_t *  element_ptr, wlmtk_pointer_motion_event_t *  motion_event_ptr  )

static

Implements wlmtk_element_vmt_t::pointer_motion. Sets cursor.

_wlmtk_rectangle_get_dimensions()

void _wlmtk_rectangle_get_dimensions ( wlmtk_element_t *  element_ptr, int *  x1_ptr, int *  y1_ptr, int *  x2_ptr, int *  y2_ptr  )

static

Implementation of the element's get_dimensions method: Return dimensions.

Parameters

element_ptr
x1_ptr	0.
y1_ptr	0.
x2_ptr	Width. May be NULL.
y2_ptr	Height. May be NULL.

handle_wlr_scene_rect_node_destroy()

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

static

Handles the 'destroy' callback of wlr_scene_rect_ptr->node.

Will reset the wlr_scene_rect_ptr value. Destruction of the node had been triggered (hence the callback).

Parameters

listener_ptr
data_ptr

test_create_destroy()

void test_create_destroy ( bs_test_t *  test_ptr )

static

Tests setup and teardown of rectangle.

test_create_destroy_scene()

void test_create_destroy_scene ( bs_test_t *  test_ptr )

static

Tests setup and teardown of rectangle, when attached to scene graph.

wlmtk_rectangle_create()

wlmtk_rectangle_t * wlmtk_rectangle_create	(	int	width,
		int	height,
		uint32_t	color
	)

Creates a rectangle. Useful for margins and borders.

Parameters

width
height
color

Returns

Pointer to the rectangle state or NULL on error.

wlmtk_rectangle_destroy()

void wlmtk_rectangle_destroy

(

wlmtk_rectangle_t *

rectangle_ptr

)

Destroys the rectangle.

Parameters

rectangle_ptr

wlmtk_rectangle_element()

wlmtk_element_t * wlmtk_rectangle_element

(

wlmtk_rectangle_t *

rectangle_ptr

)

Returns the superclass wlmtk_element_t of the rectangle.

wlmtk_rectangle_from_element()

wlmtk_rectangle_t * wlmtk_rectangle_from_element

(

wlmtk_element_t *

element_ptr

)

Gets the wlmtk_rectangle_t instance from it's element superclass.

Requires element_ptr as pointer to wlmtk_rectangle_t::super_element.

Parameters

element_ptr

Returns

The pointer to the wlmtk_rectangle_t instance.

wlmtk_rectangle_set_color()

void wlmtk_rectangle_set_color	(	wlmtk_rectangle_t *	rectangle_ptr,
		uint32_t	color
	)

Sets (or updates) the color of the rectangle.

Parameters

rectangle_ptr
color

wlmtk_rectangle_set_size()

void wlmtk_rectangle_set_size	(	wlmtk_rectangle_t *	rectangle_ptr,
		int	width,
		int	height
	)

Sets (or updates) the size of the rectangle.

Parameters

rectangle_ptr
width
height
