Prevent QLabel from resizing parent Widget

Question

I have a QLabel inside a QFrame.

Sometimes I have too much text in the QLabel and it resizes the QFrame where it is in.

Now, I want to prevent the QLabel from resizing the QFrame where it resides in. I don't want to limit the amount of lines or setting the maximum size of the QLabel because if the window size of the app increases, I do want to allow the QLabel to increase in size.

Just want to prevent the QLabel from expanding it's parent.

Any clean way to do it?

Don't put too much text in it? How do you want to handle the text that is not shown? `QLabel` is not designed to do it, you'll need a custom widget for that. — Kuba hasn't forgotten Monica, Sep 16 '16 at 14:16

Use a QScrollArea (which inherits QFrame), and hide its scrollbars:

label = QtGui.QLabel(text)
frame = QtGui.QScrollArea()
frame.setHorizontalScrollBarPolicy(QtCore.Qt.ScrollBarAlwaysOff)
frame.setVerticalScrollBarPolicy(QtCore.Qt.ScrollBarAlwaysOff)
frame.setWidgetResizable(True)
frame.setWidget(label)

This has the side-benefit that the user will still be able to view any hidden text by scrolling with the mouse-wheel.
