How do i resize the contents of a QScrollArea as more widgets are placed inside

by

If you’re coming here from Google and not having luck with the accepted answer, that’s because you’re missing the other secret invocation: QScrollArea::setWidget. You must create and explicitly identify a single widget which is to be scrolled. It’s not enough to just add the item as a child! Adding multiple items directly to the ScrollArea will also not work.

This script demonstrates a simple working example of QScrollArea:

from PySide.QtGui import *

app = QApplication([])

scroll = QScrollArea()
scroll.setWidgetResizable(True) # CRITICAL

inner = QFrame(scroll)
inner.setLayout(QVBoxLayout())

scroll.setWidget(inner) # CRITICAL

for i in range(40):
    b = QPushButton(inner)
    b.setText(str(i))
    inner.layout().addWidget(b)

scroll.show()
app.exec_()
