XUnmapWindow(3X11) XLIB FUNCTIONS XUnmapWindow(3X11)NAME
XUnmapWindow, XUnmapSubwindows - unmap windows
SYNTAX
XUnmapWindow(display, w)
Display *display;
Window w;
XUnmapSubwindows(display, w)
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 win-
dows. 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.
