[Unicon-group] polling modeless windows for events

[Daniel Boulet]

What's the best way to open multiple modeless windows (_Dialog class)  
and polls them for events?  I tried a couple of different techniques but 
neither works.  My first attempt involved open all windows "modeless" 
except the last "modal" but this did not work.  Events in the last 
window were captured but events in the first were not.  This seems to 
contradict the comments in the gui.icn source file.

I then tried a technique discussed in the "Graphics Programming in Icon" 
book (see code stub below).  This didn't work either because I'm not 
passing the correct information to the window's event handler or I'm not 
calling the correct handler.  Any suggestions would be appreciated.

Code stub:
   link win_a, win_b, win_c
   procedure main()
       a := win_a()
       b := win_b()
       c := win_c()
       a.show_modeless()
       b.show_modeless()
       c.show_modeless()
       
       repeat {
           case Active() of {
               win_a.win : win_a.dialog_event(Event(win_a.win))
               win_b.win : win_b.dialog_event(Event(win_b.win))
               win_c.win : win_c.dialog_event(Event(win_c.win))
           }
       }
       
   end
