retrieve text from popup

I am using the following code to click on a popup, and would like to be
able to retrieve the text which is displayed in the popup. Does anyone
have any suggestions as to how to do this?

def startClicker(ie, button , waitTime = 4)
   w = WinClicker.new
   longName = ie.dir.gsub("/" , "\\" )
   shortName = w.getShortFileName(longName)
   c = "start ruby #{shortName }\\clickJSDialog.rb #{button } #{
waitTime} "
   puts "Starting #{c}"
   w.winsystem(c)
   w=nil
end
