NAME
XUnmapWindow, XUnmapSubwindows - unmap windows
SYNTAX
int XUnmapWindow(Display *display, Window w);
int XUnmapSubwindows(Display *display, Window w);
ARGUMENTS
display Specifies the connection to the X server.
w Specifies the window.
DESCRIPTION
The XUnmapWindow function unmaps the specified window and causes the X server to generate an UnmapNotify
event. If the specified window is already unmapped, XUnmapWindow has no effect. Normal exposure
processing on formerly obscured windows is performed. Any child window will no longer be visible until
another map call is made on the parent. In other words, the subwindows are still mapped but are not
visible until the parent is mapped. Unmapping a window will generate Expose events on windows that were
formerly obscured by it.
XUnmapWindow can generate a BadWindow error.
The XUnmapSubwindows function unmaps all subwindows for the specified window in bottom-to-top stacking
order. It causes the X server to generate an UnmapNotify event on each subwindow and Expose events on
formerly obscured windows. Using this function is much more efficient than unmapping multiple windows
one at a time because the server needs to perform much of the work only once, for all of the windows,
rather than for each window.
XUnmapSubwindows can generate a BadWindow error.
DIAGNOSTICS
BadWindow A value for a Window argument does not name a defined Window.
