Ooops. Screwed up. The child nodes should have their
areas removed before the current node removes its
areas.
public void removeAreas() {
// still to do
int numChildren = this.children.size();
for(int i = 0; i < numChildren; i++) {
FONode fo = (FONode) children.elementAt(i);
fo.removeAreas();
}
Area parentArea;
int numAreas = this.allAreas.size();
for(int i=0; i < numAreas; i++) {
parentArea =
((Area)allAreas.elementAt(i)).getParent();
parentArea.removeChild
((Area)allAreas.elementAt(i));
}
this.marker = 0;
}
