Answer 1

// main.cpp
#include <QApplication>
#include <QDeclarativeView>
#include <QDeclarativeContext>

int main(int argc, char *argv[])
{
QApplication app(argc, argv);

QDeclarativeView view;
QDeclarativeContext *context = view.rootContext();
context->setContextProperty("backgroundColor",
QColor(Qt::yellow));

view.setSource(QUrl::fromLocalFile("main.qml"));
view.show();

return app.exec();
}
