[maemo-developers] How to get kinetic scrolling working using Qt creator

[From: Felipe Crochik]

Also make sure that the widget (imageLabel on this example) is larger than
the scrollarea contents - if you just load a small image the scroll won't
work. 

 

Even when you set the scrollbarpolicy to "show always" it will not scroll
anything unless the widget used on the QScrollArea::setWidget is larger than
the contents area.

just a quick example that would work, see if it helps.

 

    imageLabel = new QLabel;

    QImage image(someimagefile);

    imageLabel->setPixmap(QPixmap::fromImage(image));

 

    _scrollForMapPage = new QScrollArea;

    _scrollForMapPage->setWidget(imageLabel);

 

    _mapWindow = new QMainWindow ( this );

    _mapWindow->setCentralWidget(_scrollForMapPage);

    _mapWindow->show();

 

you dont need to set any property as Daniil set most widgets have kinetic
scrolling by default like ListWidget/TableWidget/ScrollArea.
