Subject: FXRuby: subwindows

Hello!

I'm using Ruby 1.6.6 and FXRuby

I'm trying to write a very small appplication:
- the main window has an FXLabel, and an FXButton: "click"
- when "click" il clicked, the application opens a subwindow, whitch
contains 4 buttons "1", "2", "3", "4"
- when one of theese buttons is choosed, the subwindow returns some value to
the main window
- the main window updates the FXLabel.text to show whitch button was
pressed.

Problem 1:
1) I've read that the main window is derived from FXMainWindow, but the
other windows are derived from such classes like FXDialogBox or FXTopWindow
2) FXDialogBow returns only true or false, and I don't want to use global
variables to handle the result in the sub window
3) FXTopLevel doesn't support .new nor .show methods
4) I'm not sure about the syntax used to return the result

Problem 2:
I've tryed to use a FXPopup instead of the subwindow, whitch contained 4
FXOptions instead of 4 buttons. I don't know how to:
- show this FXPopup when "click" is clicked
- return the result

Please could you explain what's wrong?
Thank you in advance.
