5 * © 2009 Michael Stapelberg and contributors (see also: LICENSE)
7 * ewmh.c: Get/set certain EWMH properties easily.
15 * Updates _NET_CURRENT_DESKTOP with the current desktop number.
17 * EWMH: The index of the current desktop. This is always an integer between 0
18 * and _NET_NUMBER_OF_DESKTOPS - 1.
21 void ewmh_update_current_desktop(void);
24 * Updates _NET_NUMBER_OF_DESKTOPS which we interpret as the number of
25 * noninternal workspaces.
27 void ewmh_update_number_of_desktops(void);
30 * Updates _NET_DESKTOP_NAMES: "The names of all virtual desktops. This is a
31 * list of NULL-terminated strings in UTF-8 encoding"
33 void ewmh_update_desktop_names(void);
36 * Updates _NET_DESKTOP_VIEWPORT, which is an array of pairs of cardinals that
37 * define the top left corner of each desktop's viewport.
39 void ewmh_update_desktop_viewport(void);
42 * Updates _NET_WM_DESKTOP for all windows.
43 * A request will only be made if the cached value differs from the calculated value.
46 void ewmh_update_wm_desktop(void);
49 * Updates _NET_ACTIVE_WINDOW with the currently focused window.
51 * EWMH: The window ID of the currently active window or None if no window has
55 void ewmh_update_active_window(xcb_window_t window);
58 * Updates _NET_WM_VISIBLE_NAME.
61 void ewmh_update_visible_name(xcb_window_t window, const char *name);
64 * Updates the _NET_CLIENT_LIST hint. Used for window listers.
66 void ewmh_update_client_list(xcb_window_t *list, int num_windows);
69 * Updates the _NET_CLIENT_LIST_STACKING hint. Necessary to move tabs in
72 * EWMH: These arrays contain all X Windows managed by the Window Manager.
73 * _NET_CLIENT_LIST has initial mapping order, starting with the oldest window.
74 * _NET_CLIENT_LIST_STACKING has bottom-to-top stacking order. These properties
75 * SHOULD be set and updated by the Window Manager.
78 void ewmh_update_client_list_stacking(xcb_window_t *stack, int num_windows);
81 * Set or remove _NET_WM_STATE_STICKY on the window.
84 void ewmh_update_sticky(xcb_window_t window, bool sticky);
87 * Set up the EWMH hints on the root window.
90 void ewmh_setup_hints(void);
93 * i3 currently does not support _NET_WORKAREA, because it does not correspond
94 * to i3’s concept of workspaces. See also:

99 * We need to actively delete this property because some display managers (e.g.
102 * EWMH: Contains a geometry for each desktop. These geometries specify an area
103 * that is completely contained within the viewport. Work area SHOULD be used by
104 * desktop applications to place desktop icons appropriately.
107 void ewmh_update_workarea(void);
110 * Returns the workspace container as enumerated by the EWMH desktop model.
111 * Returns NULL if no workspace could be found for the index.
113 * This is the reverse of ewmh_get_workspace_index.
116 Con *ewmh_get_workspace_by_index(uint32_t idx);
119 * Returns the EWMH desktop index for the workspace the given container is on.
120 * Returns NET_WM_DESKTOP_NONE if the desktop index cannot be determined.
122 * This is the reverse of ewmh_get_workspace_by_index.
