_NET_CLOSE_WINDOW |
Pagers wanting to close a window MUST send a _NET_CLOSE_WINDOW client message request to the root window:
_NET_CLOSE_WINDOW window = window to close message_type = _NET_CLOSE_WINDOW format = 32 data.l[0] = 0 /* may be used later */ |
The Window Manager MUST then attempt to close the window specified.
Rationale: A window manager might be more clever than the usual method (send WM_DELETE message if the protocol is selected, XKillClient otherwise). It might introduce a timeout, for example. Instead of duplicating the code, the Window Manager can easily do the job.
_NET_WM_MOVERESIZE window = window to be moved or resized message_type = _NET_WM_MOVERESIZE format = 32 data.l[0] = x_root data.l[1] = y_root data.l[2] = direction |
This message allows an application to initiate window movement or resizing. This allows the application to define its own move and size "grips", whilst letting the window manager control the actual move/resize. This means that all moves / resizes can happen in a consistent manner as defined by the WM.
When sending this message, x_root and y_root MUST indicate the position of the mouse click with respect to the root window and direction MUST indicate whether this is a move or resize event, and if it is a resize event, which edges of the window the size grip applies to.
#define _NET_WM_MOVERESIZE_SIZE_TOPLEFT 0 #define _NET_WM_MOVERESIZE_SIZE_TOP 1 #define _NET_WM_MOVERESIZE_SIZE_TOPRIGHT 2 #define _NET_WM_MOVERESIZE_SIZE_RIGHT 3 #define _NET_WM_MOVERESIZE_SIZE_BOTTOMRIGHT 4 #define _NET_WM_MOVERESIZE_SIZE_BOTTOM 5 #define _NET_WM_MOVERESIZE_SIZE_BOTTOMLEFT 6 #define _NET_WM_MOVERESIZE_SIZE_LEFT 7 #define _NET_WM_MOVERESIZE_MOVE 8 /* Movement only */ |
The client MUST release all grabs on Pointer events, prior to sending such message.
