_wlmaker_layer_panel_apply_layer()

bool _wlmaker_layer_panel_apply_layer ( wlmaker_layer_panel_t * layer_panel_ptr, enum zwlr_layer_shell_v1_layer zwlr_layer )

static

Updates the layer this panel is part of. Posts an error if invalid.

_wlmaker_layer_panel_create_injected()

wlmaker_layer_panel_t * _wlmaker_layer_panel_create_injected ( struct wlr_layer_surface_v1 * wlr_layer_surface_v1_ptr, wlmaker_server_t * server_ptr, wlmtk_surface_create_t wlmtk_surface_create_fn )

static

Constructor for the layer panel, with injectable methods.

Parameters

wlr_layer_surface_v1_ptr
server_ptr
wlmtk_surface_create_fn

Returns

The handler for the layer surface or NULL on error.

_wlmaker_layer_panel_destroy()

void _wlmaker_layer_panel_destroy ( wlmaker_layer_panel_t * layer_panel_ptr )

static

Destroys the layer panel and frees up all associated resources.

Parameters

layer_panel_ptr

_wlmaker_layer_panel_handle_destroy()

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

static

Handler for the destroy signal of the wlr_layer_surface_v1: Destroys the panel.

Parameters

listener_ptr
data_ptr

_wlmaker_layer_panel_handle_new_popup()

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

static

Handler for the new_popup signal of the wlr_layer_surface_v1: Creates a new popup for this panel.

Parameters

listener_ptr
data_ptr	Points to the new struct wlr_xdg_popup.

_wlmaker_layer_panel_handle_surface_commit()

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

static

Handler for the commit signal of wlr_surface.

Updates positioning and layer of the panel, as required.

Parameters

listener_ptr
data_ptr

_wlmaker_layer_panel_handle_surface_map()

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

static

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

static

Handler for the unmap signal of wlmtk_surface_t: Unmaps the panel.

Parameters

listener_ptr
data_ptr

_wlmaker_layer_panel_request_size()

uint32_t _wlmaker_layer_panel_request_size ( wlmtk_panel_t * panel_ptr, int width, int height )

static

Implements wlmtk_panel_vmt_t::request_size.

_wlmaker_layer_panel_set_positioning()

void _wlmaker_layer_panel_set_positioning ( wlmtk_panel_positioning_t * positioning_ptr, const struct wlr_layer_surface_v1_state * state_ptr )

static

Updates positioning_ptr from the given surface state.

test_create_destroy()

void test_create_destroy ( bs_test_t * test_ptr )

static

Exercises creation and teardown.

wlmaker_layer_panel_create()

wlmaker_layer_panel_t * wlmaker_layer_panel_create	(	struct wlr_layer_surface_v1 *	wlr_layer_surface_v1_ptr,
		wlmaker_server_t *	server_ptr )

Creates a layer panel for the given layer surface.

A layer panel is the implementation of a WLroots layer shell surface.

Parameters

wlr_layer_surface_v1_ptr
server_ptr

Returns

The handler for the layer surface or NULL on error. The associated resources will be destroyed once wlr_layer_surface_v1_ptr is destroyed.
