Question

I have a QWidget.
And inside the QWidget, I have a lot of other QWidgets, eg:- QComboBox, QLineEdit, etc ….

Now, I wanna detect if the user has made any changes (eg:- write something in the QLineEdit, or changed the value on the QComboBox, etc …..)

Is there an easy way to do that?
Or do I need to capture each and every widget’s signal, like this …

QObject.connect(lineedit, SIGNAL("textchanged()"), doSomething)
QObject.connect(combobox, SIGNAL("currentIndexChanged(int)"), doSomething)
... ... ...

Yes, you have to connect up the signals manually.
