resize event

How use resize event for QDialog ? I try like this, but not work.

Qt Code:

Switch view

...............
...............
connect(this, SIGNAL(resizeEvent ( QResizeEvent * event )), this, SLOT(coba( QResizeEvent * event )));
...............
...............
 
void myDialog::coba( QResizeEvent * event )
{
    qDebug() << size();
}

...............
...............
connect(this, SIGNAL(resizeEvent ( QResizeEvent * event )), this, SLOT(coba( QResizeEvent * event )));
...............
...............

void myDialog::coba( QResizeEvent * event )
{
    qDebug() << size();
}

To copy to clipboard, switch view to plain text mode

resizeEvent is not a signal... its a virtual function... use it directly..(first declare it in your class)

void myDialog::resizeEvent(QResizeEvent*)

Qt Code:

Switch view

class myDialog
{
protected:
  void resizeEvent(QResizeEvent *event);
};
 
void myDialog::resizeEvent(QResizeEvent *event)
{
    qDebug() << event->size() << event->oldSize();
}

class myDialog
{
protected:
  void resizeEvent(QResizeEvent *event);
};

void myDialog::resizeEvent(QResizeEvent *event)
{
    qDebug() << event->size() << event->oldSize();
}

To copy to clipboard, switch view to plain text mode

EDIT: too late...

i) resizeEvent is a regular virtual protected function, just overload it in your class and handle the event
ii) if it was a signal (it is not), your syntax would be wrong:

connect(this, SIGNAL(resizeEvent ( QResizeEvent * event )), this, SLOT(coba( QResizeEvent * event )));

you must not have argument names in there, it would be
connect(this, SIGNAL(resizeEvent(QResizeEvent*)), this, SLOT(coba(QResizeEvent*)));(Of course, this will not work, as resizeEvent is NOT a signal.)
