[pygtk] My dialog is empty when opened for second time

[Lionel Dricot]

Your object exists only once in self.builder and you destroy it so you
cannot retrieve it.

Instead of destroy, you should use "hide()" and instead of getting your
object each time from the builder, you should use "show()".

Don't worry, that's a common error when starting with pygtk :-)

PS: I would write it this way (untested) :

   class Sample:
   def __init__ (self):
       self.builder = gtk.Builder()
       self.builder.add_from_file("../data/sample.glade")
       self.builder.connect_signals(self)
       self.dialog = self.builder.get_object("dialog1")
       self.label = self.builder.get_object("label2")


       self.window = self.builder.get_object("mywindow")
       self.window.set_modal(True)
       self.window.show_all()

   def addDialog(self, sender):
       self.dialog.show()
       print self.label.get_text()
       print self.dialog.get_title()
       result = self.dialog.run()
       if result == 1 :
           print "ok!"
       else :
           print "no"
        dialog.hide()
