Putting a scroll bar into a grid-placed widget

john_hobbyist

I have a grid layout with Qlabels . Because there any many rows...around 150 rows with labels, I am trying to put a scroll bar on the right. But it does not work although I tried many configurations from googling search. Can you help?

I am using this code (source: https://www.geeksforgeeks.org/pyqt5-qlistwidget-adding-extra-scroll-bar-to-it/):

    win = QWidget()
    mygrid=QGridLayout()
 
    # scroll bar
    scroll_bar = QScrollBar(self)

    # setting style sheet to the scroll bar
    scroll_bar.setStyleSheet("background : lightgreen;")

    # adding extra scroll bar to it
    mygrid.addScrollBarWidget(scroll_bar, Qt.AlignLeft)

You can't add that to a layout. My expectation, I think, would be to use a QScrollArea around a QWidget containing your QGridLayout.

[UPDATE I see the latest new post while I was writing this, https://forum.qt.io/topic/138690/layout-for-qscrollarea-to-expand-horizontally-vertically, uses just this approach.]

Nothing to do with C++.

@JonB The link you posted, has implementation in C/C++ which I do not understand...

I merely mentioned it happened to be a post using that approach which had just been made, suggesting that was the way to go. If you like, forget I even mentioned it.

If you want to wait till any example is in Python that is up to you.
