Now we can use one widget to input a number and another to display it. Or if the sending widget to which we are connected intentionally emptied None is sent to the widget when a connection between the widgets is removed Notice how in the set_number method we check whether the number is None. The handlers by decorating them in above case by putting the method’s definition. However, each input must be handled by a class methods. We define inputs with a class Inputs, just like outputs are defined by setText ( "The number is: ?" ) else : self. number def set_number ( self, number ): """Set the input number.""" self.

We specify the default layout with class attribute flags. Visual look, you can use these areas in any way you want, evenĭisregarding one and composing your widget completely unlike the Notice that while it would be nice for all widgets to have this common Through its attributes ntrolArea and self.mainArea.
