I have a JPanel with a bunch of JComponents inside. Now I want that the
user can drag the mouse over all of them and draw a selection rectangle
over them.

How do I do that? Do I have to use and implement the glassPane?

Isn't there a standard method? It's what every File Explorer does: There
are some Icons and you draw a selection rectangle to select some of
them... I can handle the selection later. Now I just want to draw the
selection rectangle.

Thanks!
Andi
