[PyQt4] check if value of QLabel changed

[ja.heller]

I Need to check if the value (str) of a qlabel changed.
I think about using the following code (nearly the same as used by a spinbox widget in PyQt):


self.connect(self.ui.labelEntry, QtCore.SIGNAL("valueChanged(str)"), self.autovalidate)

What's the correct Methode to check if value changed?

All the best;

QLabel doesn't have a change signal for its text property.

The only way that the label text can change is if your program code changes it, so there is little point in the label separately announcing that it changed.
