[Qt-interest] scroll area from designer

[Duane Hebert]

I need to use a scroll area and fill it up with some widgets at runtime.
I can put a frame on a form in designer, then at run time, build a scroll area with the frame as parent, create a group box, set the 
groupbox as the widget for the scroll area and create my widgets with the group box as a parent.  When I'm done, I can call 
adjustSize() on the group box.

Like:

QScrollArea *Scroll = new QScrollArea(ui.frame);
QGroupBox *Box = new QGroupBox(this);
Scroll->setWidget(Box);

  int yPos(0);
   for(int i = 0; i < 20; ++i) {
      QPushButton *pb = new QPushButton(Box);
      pb->setText(QString::number(i));
      pb->move(0,yPos);
      yPos += 20;
   }

   Box->adjustSize();
   Box->show();
   Box->adjustSize();
   Box->show();

This works, but then I have to size the scroll area to the correct size and handle resize events to do the same.

What's the correct way to do this from Designer?  There's a QScrollArea that I can drop on the form, but I don't see a way to use 
this.

Thanks.
