Function Documentation

_wlmaker_layer_from_zwlr_layer()

wlmtk_workspace_layer_t _wlmaker_layer_from_zwlr_layer

(

enum zwlr_layer_shell_v1_layer

zwlr_layer

)

Returns

Layer number, translated from protocol value. -1 on error.

_wlmaker_layer_panel_apply_keyboard()

bool _wlmaker_layer_panel_apply_keyboard ( wlmaker_layer_panel_t *  layer_panel_ptr, enum zwlr_layer_surface_v1_keyboard_interactivity  interactivity, enum zwlr_layer_shell_v1_layer  zwlr_layer  )

static

Applies the requested keyboard setting.

Supports 'NONE' and 'EXCLUSIVE' interactivity, but the latter only on top and overlay layers.

TODO(kaese.nosp@m.r@gu.nosp@m.bbe.c.nosp@m.h): Implement full support, once layer elements have a means to organically obtain and release keyboard focus (eg. through pointer button clicks).

Parameters

layer_panel_ptr
interactivity
zwlr_layer

Returns

true on success.

_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_element_destroy()

void _wlmaker_layer_panel_element_destroy ( wlmtk_element_t *  element_ptr )

static

Implements wlmtk_element_vmt_t::destroy, forwards to _wlmaker_layer_panel_destroy.

Parameters

element_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

Handler for the map signal of wlmtk_surface_t: Maps the panel to layer.

Parameters

listener_ptr
data_ptr

_wlmaker_layer_panel_handle_surface_unmap()

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.

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.
