GIF animation in Qt

Question

I have used QGraphicsView, QGraphicsScene classes in order to show a picture in a widget like this:

m_Scene->addPixmap(QPixmap(fileName));
m_View->setScene(m_Scene);

How I can show .gif animation in the same scene?

Answer 1

http://doc.qt.nokia.com/4.6/qmovie.html

google and Qt docs are your friend. The Trolls even have an example

PS: unless you're in China, then google is unaccessible, but you'd have stuff like Bing and doc.qt.nokia.com

PS2: for a little more in-depth answer: you can use a QGraphicsProxyWidget of a QLabel which has a QMovie via QLabel::setMovie. There's probably an easier/shorter way to do it.

Answer 2

Don't use GIF animation with QGraphicsView or QGraphicsScene, use it only in QDialog, but I think it's the same stuff, so here is my code:

QMovie *movie = new QMovie(":/images/other/images/16x16/loading.gif");
QLabel *processLabel = new QLabel(this);
processLabel->setMovie(movie);
movie->start();

My loading.gif I took from this link.

PS: also check the examples from Qt SDK. They are really can help!
