I have a file browser class based on FXFileList which has a 
context-sensitive popup. FXFileList is based on FXIconList, so the same 
technique would work. I'll try to extract a snippet, but if you want the 
full code it's in my foxtails package on RAA. Look at 
lib/foxtails/FTFileBrowser.rb and examples/file-browser.rb.

When initializing, you connect the icon list with this method call:

       connect(SEL_RIGHTBUTTONRELEASE, method(:onPopupMenu))

and define onPopupMenu as in FXFileSelector::onPopupMenu in the fox source:

     def onPopupMenu sender, sel, event
       if event.moved then return 1 end

       index = getItemAt(event.win_x, event.win_y)

       filemenu = FXMenuPane.new(self)

       ### Add your menu items here ###

       FXMenuCommand.new(filemenu, ...)

       filemenu.create()
       filemenu.popup(nil, event.root_x, event.root_y)
       filemenu.grabKeyboard
       getApp().runModalWhileShown(filemenu)
       return 1
     end

I haven't noticed any delay whatsoever in dynamically creating panes 
like this. YMMV.

FoxTails also has dynamically generated popup menu buttons (see 
examples/simple.rb and lib/foxtails/FTPopupButton.rb).
