I have the following code for a labelProvider:
class ViewLabelProvider extends LabelProvider implements IColorProvider{
....
...
public Image getImage(Object obj) {
....
}

public Color getForeground(Object element) {
...
}

public Color getBackground(Object element) {
....
}

}
which of these three function are called first when the viewer is
associated with this label provider
Say,
TreeViewer tv = new TreeViewer(...);
tv.setLabelProvider(new ViewLabelProvider());

and is the order of call same always, i.e when tree is expanded or
collapsed etc..

If you add some debug messages in each of the methods, you'll find out
that..

1. getImage(...)
2. getForeground(...)
3. getBackground(...)
4. getFont(...)
5. Looks like it
