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.
DescriptionXtUnmanageChild() 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 call‐
ing 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.
