       #widget.connect("_checkbox", "toggled(bool)", toggledCheckBox)
       widget.connect("_button", "clicked()", clickedButton)
       widget.connect("_button", "clicked()", "print 'Clicked button2!'")
       widget.connect("_spinbox", "valueChanged(int)", valueChanged1)
       widget.connect("_slider", "valueChanged(int)", valueChanged2)
       
       # creates a new widget2 instance from checkbox, just a test ...
       checkbox = findQObject(widget.getQObject(), "_checkbox")
       widget2 = vrWidget(checkbox)
       widget2.connect("_checkbox", "toggled(bool)", toggledCheckBox)
       
       lineedit = findQObject(widget.getQObject(), "_lineedit")

       print "lineedit enabled = ", lineedit.getProperty("enabled")
       print "lineedit text = ", lineedit.getProperty("text")
