XtUnmanageChild()														 XtUnmanageChild()

Name
  XtUnmanageChild - remove a widget from its parent's managed list.

Synopsis
  void XtUnmanageChild(w)
	 Widget w;

Inputs
  w	    Specifies the child widget to be unmanaged; must be of class RectObj or any subclass thereof.

Description
  XtUnmanageChild()  unmaps  the  specified  widget and removes it from its parent's geometry management.  The widget will disappear from the
  screen, and (depending on its parent) may no longer have screen space allocated for it.

  XtUnmanageChild() simply calls XtUnmanageChildren().	See that function for more information about the procedure for unmanaging a widget.

Usage
  Unmanaging a widget is the usual method for temporarily making it invisible.	It can be re-managed with XtManageChild().

  You can unmap a widget, but leave it under geometry management by calling XtUnmapWidget().  You  can	destroy  a  widget's  window  without
  destroying the widget by calling XtUnrealizeWidget().  You can destroy a widget completely with XtDestroyWidget().

  If  you  will be unmanaging several sibling widgets, it is more efficient to call XtUnmanageChildren() because this only generates a single
  call to the parent's change_managed() method.  It is often more convenient to simply call XtUnmanageChild() several times, however.
