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©
w=nil
end
