7 * x.c: Interface to X11, transfers our in-memory state to X11 (see also
8 * render.c). Basically a big state machine.
14 /** Stores the X11 window ID of the currently focused window */
15 extern xcb_window_t focused_id;
18 * Initializes the X11 part for the given container. Called exactly once for
19 * every container from con_new().
22 void x_con_init(Con *con, uint16_t depth);
25 * Moves a child window from Container src to Container dest.
28 void x_move_win(Con *src, Con *dest);
31 * Reparents the child window of the given container (necessary for sticky
32 * containers). The reparenting happens in the next call of x_push_changes().
35 void x_reparent_child(Con *con, Con *old);
38 * Re-initializes the associated X window state for this container. You have
39 * to call this when you assign a client to an empty container to ensure that
40 * its state gets updated correctly.
43 void x_reinit(Con *con);
46 * Kills the window decoration associated with the given container.
49 void x_con_kill(Con *con);
52 * Returns true if the client supports the given protocol atom (like WM_DELETE_WINDOW)
55 bool window_supports_protocol(xcb_window_t window, xcb_atom_t atom);
58 * Kills the given X11 window using WM_DELETE_WINDOW (if supported).
61 void x_window_kill(xcb_window_t window, kill_window_t kill_window);
64 * Draws the decoration of the given container onto its parent.
67 void x_draw_decoration(Con *con);
70 * Recursively calls x_draw_decoration. This cannot be done in x_push_node
71 * because x_push_node uses focus order to recurse (see the comment above)
72 * while drawing the decoration needs to happen in the actual order.
75 void x_deco_recurse(Con *con);
78 * This function pushes the properties of each node of the layout tree to
79 * X11 if they have changed (like the map state, position of the window, …).
80 * It recursively traverses all children of the given node.
83 void x_push_node(Con *con);
86 * Pushes all changes (state of each node, see x_push_node() and the window
90 void x_push_changes(Con *con);
93 * Raises the specified container in the internal stack of X windows. The
94 * next call to x_push_changes() will make the change visible in X11.
97 void x_raise_con(Con *con);
100 * Sets the WM_NAME property (so, no UTF8, but used only for debugging anyways)
101 * of the given name. Used for properly tagging the windows for easily spotting
102 * i3 windows in xwininfo -root -all.
105 void x_set_name(Con *con, const char *name);
108 * Sets up i3 specific atoms (I3_SOCKET_PATH and I3_CONFIG_PATH)
111 void x_set_i3_atoms(void);
114 * Set warp_to coordinates. This will trigger on the next call to
118 void x_set_warp_to(Rect *rect);
121 * Applies the given mask to the event mask of every i3 window decoration X11
122 * window. This is useful to disable EnterNotify while resizing so that focus
