widget qgraphicsview scaling

[mistertoony]

i used this code:

void scalingApp::resizeEvent(QResizeEvent *event)
{
     QWidget::resizeEvent(event);
     graphicsView->resize(width(),220);
}

void scalingApp::resizeEvent(QResizeEvent *event)
{
     QWidget::resizeEvent(event);
     graphicsView->resize(width(),220);
}

To copy to clipboard, switch view to plain text mode 

this allows the graphicsview to only be resize'ed horizontally. however, the button is fixed and doesnt move to the right like i would like it to. (the button is situated on the bottom within a horizontal layout including the button and a horizontal spacer) any hints/help?
