I did try:

h.callback="disp(xclick())";  //disp can obviously be replaced with a suitable selection function.

I can get it to work in a two click mode: First click the button, then 
click an image next to the button.

The problem with making one big button with the picture on top, is that 
xclick() will not give the correct cursor position when on top of a 
button. Just static values [-2. -1. -1.].

"cbmenu - String: callback associated to a menu if |xclick| returns due 
to a click on a menu. In this case, |ibutton|, |xcoord|, |ycoord|, and 
|iwin| take arbitrary values".
