Hi,
Am using Qt 4.8.x with UI components based on QWidgets.
In the custom implementation of resize event handler, I would like to
know if it is mandatory to invoke QWidget base implementation of
resizeEvent or not
It's not. The default implementation is empty. You can check that
yourself by looking at the source file where QWidget is implemented
(src/gui/kernel/qwidget.cpp):
void QWidget::resizeEvent(QResizeEvent * /* event */)
{
}
However, I usually still call the base class implementations of
functions like that, because some of them might need to be called. For
the ones that are empty, calling them doesn't hurt.
