How to animate changing widget position in QVBoxLayout

Question

Widget position in QVBoxLayout can be changed by

layout->insertWidget(new_widget_position, 
                     layout->takeAt(current_widget_position)->widget())

I would like to animate widget position change in sliding animation.

Answer 1

That is not possible with a QBoxLayout.

But it is easily possible to layout manually using setGeometry();

This can be called continuously timer controlled with varying coordinates.

Or you can facilitate QPropertyAnimation to handle timing and start and end position for you.
