Are you sure about the fact that the image itself is transparent.Try opening the image in paint etc with a black background & see if white background of image is still visible.

I am not 100% sure about the image. But with gimp 2.6 it looks the image is transparent.
RHS is taken from gimp editor and LHS is windows paint. Is it not transparent? See the image from here http://hemelix.com/imagecompare.png or

Thanks but it did not help me. It is qml app that load qml file and I use the png file
I have a code like this
QScopedPointer<QApplication> app(createApplication(argc, argv));


//QScopedPointer<QmlApplicationViewer> viewer(QmlApplicationViewer::create());
QmlApplicationViewer viewer;



viewer.setAttribute(Qt::WA_OpaquePaintEvent);
viewer.setAttribute(Qt::WA_NoSystemBackground);
viewer.viewport()->setAttribute(Qt::WA_OpaquePaintEvent);
viewer.viewport()->setAttribute(Qt::WA_NoSystemBackground);

//viewer.setStyleSheet("background:transparent;");
viewer.setOrientation(QmlApplicationViewer::ScreenOrientationLockPortrait);

Make sure that the rectangle behind your image is transparent, by default it is white
