How to add horizontal and verticle scroll bar to the QDialog? if the values in the qdialog goes downwards or rightwards. so that the scrollbar should appear automatically?

[Lesiok]

On QDialog put QScrollArea and all widgets put on this area.

I have tried doing that.. But nothing happens.. here is the code

scroll = new QScrollArea();
scroll->setHorizontalScrollBarPolicy(Qt::ScrollBarAsNeeded)
scroll->setVerticalScrollBarPolicy(Qt::ScrollBarAsNeeded)
scroll->setParent(this);
scroll-> setVisible(true);

scroll = new QScrollArea();
scroll->setHorizontalScrollBarPolicy(Qt::ScrollBarAsNeeded)
scroll->setVerticalScrollBarPolicy(Qt::ScrollBarAsNeeded)
scroll->setParent(this);
scroll-> setVisible(true);

To copy to clipboard, switch view to plain text mode

Your scroll area has no content currently.

Is there anything to do with the above code provided?

[wysota]

What did you put in the scroll area? Is there anything at all? Did you put the scroll area in your widget's layout?

Did you even read the example in QScrollArea docs? Do you see the differences between your code and the code of the example? Do you understand how QScrollArea works?
