How to resize the QToolButton when focus is coming on that QToolButton

Question

How to resize the QToolButton when focus is coming on that QToolButton. I am having 5 QToolButton, when focus is coming on 2nd QTool

Answer 1

It is also possible via QSS:

#MySecondButton:focus
{
  width: 300px;
  height: 200px;
}

Depends on layouting and size policy it may require to set "max-width" / "max-height" / "min-width" etc, properties.
