XtManageChildren(3X)						   XT FUNCTIONS 					      XtManageChildren(3X)

NAME

       XtManageChildren - manage children

SYNTAX

       void XtManageChildren(children, num_children)
	     WidgetList children;
	     Cardinal num_children;

ARGUMENTS

       children  Specifies a list of child widgets.

       num_children
		 Specifies the number of children.

DESCRIPTION

       The XtManageChildren function performs the following:

       o    Issues an error if the children do not all have the same parent or if the parent is not a subclass of compositeWidgetClass.

       o    Returns immediately if the common parent is being destroyed; otherwise, for each unique child on the list, XtManageChildren ignores
	    the child if it already is managed or is being destroyed and marks it if not.

       o    If the parent is realized and after all children have been marked, it makes some of the newly managed children viewable:

	    -	 Calls the change_managed routine of the widgets' parent.

	    -	 Calls XtRealizeWidget on each previously unmanaged child that is unrealized.

	    -	 Maps each previously unmanaged child that has map_when_managed True.

       Managing children is independent of the ordering of children and independent of creating and deleting children.	The layout routine of the
       parent should consider children whose managed field is True and should ignore all other children.  Note that some composite widgets, espe-
       cially fixed boxes, call XtManageChild from their insert_child procedure.

       If the parent widget is realized, its change_managed procedure is called to notify it that its set of managed children has changed.  The
       parent can reposition and resize any of its children.  It moves each child as needed by calling XtMoveWidget, which first updates the x and
       y fields and then calls XMoveWindow if the widget is realized.
