3. The KidGeometryRec

XmKidGeometryRecThe final structure is the most important one: the XmKidGeometry structure. This structure contains the geometry for a child, and provides a storage place during the layout calculations for that geometry while the algorithms proceed.

typedef struct _XmKidGeometryRec {
    Widget kid;
    XtWidgetGeometry box;
} XmKidGeometryRec, *XmKidGeometry;
