QGraphicsView::scale not working
Unsolved

Hi,
I implemented the code below.
The initial GUI is correct but when I later call to ‘m_pView->scale’ then it is not working, the scale is not changing and nothing happens.
Any idea what I did wrong?class AppMainWnd : public QMainWindow { QGraphicsScene* m_pScene; QGraphicsView* m_pView; } AppMainWnd::AppMainWnd() { // ... m_pView = new QGraphicsView(this); m_pScene = new QGraphicsScene(this); m_pView->setVerticalScrollBarPolicy(Qt::ScrollBarAlwaysOff); m_pView->setHorizontalScrollBarPolicy(Qt::ScrollBarAlwaysOff); m_pView->setScene(m_pScene); ui->verticalLayout->setParent(m_pView); // verticalLayout is of type QVBoxLayout* setCentralWidget(m_pView); QWidget* pMainDisplay = CreateMainDisplay(); m_pView->setViewport(pMainDisplay); ui->verticalLayout->setAlignment(Qt::AlignCenter); ui->verticalLayout->addWidget(pMainDisplay); // ... } void AppMainWnd::ScaleUI(double dFactor) { m_pView->scale(dFactor, dFactor); // This does NOT work }
