QScrollArea is a widget container for widgets, whose size is usually very large and that the window with them fits, add scroll bars (sliders).

To place widgets in QScrollArea need not a layout (layout), but a widget, so it has a setWidget method.

For example, this code will create a large number of buttons:

 from PyQt5 import Qt app = Qt.QApplication([]) layout = Qt.QGridLayout() for i in range(10): for j in range(5): button = Qt.QPushButton('{}x{}'.format(i, j)) layout.addWidget(button, i, j) w = Qt.QWidget() w.setLayout(layout) mw = Qt.QScrollArea() mw.setWidget(w) mw.resize(200, 200) mw.show() app.exec()

The window will look like this:

When you increase the window size, the sliders will disappear:

QScrollArea can resize widgets in it, stretch them. The widgetResizable property, which is False by default, is responsible for this.

If QScrollArea activates this property ( mw.setWidgetResizable(True) ), then the widgets in it will stretch:
