Question

OK so I’ve got a JPanel with a GridLayout. Each cell of the grid then contains another JPanel.

What I’d like to be able to do is have a listener on the “underneath” JPanel which then tells me which of the “overlayed” JPanels was clicked – so I can react to it and the surrounding ones, without making the covering JPanels aware of their position (they change!!)

Is there a way of doing this – similar to Determine clicked JPanel component in the MouseListener. Event handling but I couldn’t find a way of grabbing the component on top.

I could probably grab the co-oridnates and work it out using that info – but I’d rather not!!

Any help/pointers/tips would be appreciated 😀

Do the same thing but use getParent() on the source. Or you can search up the hierarchy if it is deeper, even some helper methods for that:
javax.swing.SwingUtilities.getAncestorOfClass and getAncestorNamed
