Hi Martin,
Since my project is not a qml project but a C++ one, I have to deploy
the qml with the executable. So to do that I use a resource .qrc file
that has reference to my qml files:
<RCC>
<qresource prefix="/">
<file>qml/main.qml</file>
<file>qml/RssModel.qml</file>
</qresource>
</RCC>
This has the effect that the qml are available but the path to them is
now a resource path not a file system path.
To access the qml from C++ I do the following:
ui->declarativeView->setSource(QUrl::fromLocalFile(":/qml/main.qml"));
This works perfectly if I don't use import Qt.multimedia, so it is not
the path.
What I can see is that when run as a direct qml project, tvtennis is
loading
QDeclarativeEngine::importPlugin "Qt.multimedia" from
"C:/Qt/qtcreator-1.3.83/bin/Qt/multimedia/multimedia.dll"
So when using QML projects I am not using my Qt 4.7 installed in
C:\Qt\4.7.0-beta1\ instead I am using the one that came with QtCreator
and something triggers loading those libraries as plugins.
Now , my Qt 4.7 beta 1 also have this libraries in
C:\Qt\4.7.0-beta1\imports\Qt\multimedia\ but I do not know what should I
do to make them load as plugins when qml engine starts. It is probably
something that the qml viewer does and my project doesn't.
Any help is appreciated.
Regards,
Cristi
