One of the toughest challenges facing a new Motif developer is determining which widgets can be children of which parents. ICS recommends that new Motif developers select "Keep Parent" (Main Window->View). The Keep Parent option only allows valid children of the currently selected widget to be selected on the palette. In Keep Parent mode, you first select which object is going to be the parent by clicking on it in your user interface or in the Browser. Widgets on the palette that remain sensitive are valid children of the currently selected widget. All Widgets that are NOT valid children are grayed out.
