我实现了Qquick1.1下在
qml中嵌入mplayer进行播放的功能, 代码公开如下. 希望有大家能共同出力,在Qquick2.0环境下也能实现类似的功能.
#include "qtquick1applicationviewer.h"

#include "applicationdata.h"
int main(int argc, char *argv[])
{
QApplication app(argc, argv);
QDeclarativeView viewer;
qDebug() << &viewer;
ApplicationData *data = new ApplicationData();
data->setView(&viewer);
viewer.rootContext()->setContextProperty("applicationData", data);
viewer.rootContext()->setContextProperty("view", &viewer);
viewer.setSource(QUrl("qrc:///mymain.qml"));
viewer.show();
return app.exec();
}
