References CIRCLEQ_FOREACH, ELOG, con_state::id, and state.

bool window_supports_protocol ( xcb_window_t  window,
xcb_atom_t  atom 
)

Returns true if the client supports the given protocol atom (like WM_DELETE_WINDOW)

Definition at line 240 of file x.c.

References conn, xcb_icccm_get_wm_protocols, xcb_icccm_get_wm_protocols_reply, xcb_icccm_get_wm_protocols_reply_t, and xcb_icccm_get_wm_protocols_reply_wipe.

void x_con_init ( Con con,
uint16_t  depth 
)

Initializes the X11 part for the given container.

Called exactly once for every container from con_new().

Definition at line 88 of file x.c.

void x_con_kill ( Con con)

Kills the window decoration associated with the given container.

References CIRCLEQ_REMOVE, conn, focused_id, Con::frame, FREE, con_state::name, Con::pixmap, Con::pm_gc, and state.

Referenced by tree_close().

void x_deco_recurse ( Con con)

Recursively calls x_draw_decoration.

This cannot be done in x_push_node because x_push_node uses focus order to recurse (see the comment above) while drawing the decoration needs to happen in the actual order.

Here is the call graph for this function:

void x_draw_decoration ( Con con)
void x_mask_event_mask ( uint32_t  mask)

Applies the given mask to the event mask of every i3 window decoration X11 window.

This is useful to disable EnterNotify while resizing so that focus is untouched.

void x_raise_con ( Con con)

Raises the specified container in the internal stack of X windows.

The next call to x_push_changes() will make the change visible in X11.

void x_reinit ( Con con)

Re-initializes the associated X window state for this container.

You have to call this when you assign a client to an empty container to ensure that its state gets updated correctly.

void x_reparent_child ( Con con,
Con old 
)

Reparents the child window of the given container (necessary for sticky containers).

The reparenting happens in the next call of x_push_changes().

Referenced by cmd_reload(), and main().

void x_set_name ( Con con,
const char *  name

Sets the WM_NAME property (so, no UTF8, but used only for debugging anyways) of the given name.

Used for properly tagging the windows for easily spotting i3 windows in xwininfo -root -all.
