Functions

void x_con_init (Con *con)
 Initializes the X11 part for the given container.
void x_move_win (Con *src, Con *dest)
 Moves a child window from Container src to Container dest.
void x_reparent_child (Con *con, Con *old)
 Reparents the child window of the given container (necessary for sticky containers).
void x_reinit (Con *con)
 Re-initializes the associated X window state for this container.
void x_con_kill (Con *con)
 Kills the window decoration associated with the given container.
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).
void x_window_kill (xcb_window_t window, kill_window_t kill_window)
 Kills the given X11 window using WM_DELETE_WINDOW (if supported).
void x_draw_decoration (Con *con)
 Draws the decoration of the given container onto its parent.
void x_deco_recurse (Con *con)
 Recursively calls x_draw_decoration.
void x_push_node (Con *con)
 This function pushes the properties of each node of the layout tree to X11 if they have changed (like the map state, position of the window, …).
void x_push_changes (Con *con)
 Pushes all changes (state of each node, see x_push_node() and the window stack) to X11.
void x_raise_con (Con *con)
 Raises the specified container in the internal stack of X windows.
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.
void x_set_i3_atoms ()
 Sets up i3 specific atoms (I3_SOCKET_PATH and I3_CONFIG_PATH).

Variables

xcb_window_t focused_id
 Stores the X11 window ID of the currently focused window.

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).

void x_con_init ( Con con  ) 

Initializes the X11 part for the given container.

Called exactly once for every container from con_new().

Here is the call graph for this function:

void x_con_kill ( Con con  ) 

Kills the window decoration associated with the given container.

Definition at line 162 of file x.c.

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

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.

void x_draw_decoration ( Con con  ) 
void x_move_win ( Con src,
Con dest 
)

Moves a child window from Container src to Container dest.

Definition at line 138 of file x.c.

References DLOG, ELOG, Con::frame, and con_state::window_rect.

Referenced by workspace_reassign_sticky().

void x_push_changes ( Con con  ) 
void x_push_node ( Con con  ) 
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.

Referenced by render_con(), and render_l_output().

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.

Definition at line 104 of file x.c.

References con_state::child_mapped, DLOG, ELOG, Con::frame, con_state::initial, and con_state::window_rect.

Referenced by manage_window().

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().

References ELOG, Con::frame, con_state::need_reparent, and con_state::old_frame.

Referenced by workspace_reassign_sticky().

void x_set_i3_atoms (  ) 

Sets up i3 specific atoms (I3_SOCKET_PATH and I3_CONFIG_PATH).

Referenced by main(), and yyparse().

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.
