I'd like to ask a question about PICK device.

I use PEX in the window which is a child of an athena widget. But I
can't get any information about the structure picked by the mouse. 
What should I do for the purpose of getting the information?

First, I initialize and create the top widget, then create paned
widget as a child of it, create a simple widget as one of children of
the paned widget, open phigs and bind it to the simple widget.

I can draw picture in the window and I can extract events of pick, but
I cannot extract which structure is picked.

Thanks in advance.
