How to register mouse_down on backpanel?

Question

Hi. Here is an image to illustrate what i mean:

I have one backpanel that listens to mouse_down event. Infront of that backpanel i have another panel(Overlaying panel), and a label in top.

If i push the mousebutton on the label or the "Overlaying panel", nothing is registered.

Is it possible to just make the backpanel listen for mouse actions, or do i have to create listeners for the other panel and label to?

Thanks in advance
