[SOLVED] main.cpp procedure question

[jediengineer]

I'm still a little new to Qt - please bear with me.

When I create a new QtQuick Application, in the main.cpp file I have the following in my main function:

@
QtQuick2ApplicationViewer viewer;
viewer.setMainQmlFile(QStringLiteral("qml/01-048-2801-Rev1/main.qml"));
viewer.showExpanded();
@

What is the difference between that method of initialization and this one:

@
QQuickView* view = new QQuickView(QUrl("qml/01-048-2801-Rev1/main.qml"));
view->show();
@

And if I'm writing a GUI that calls a lot of C++ functions, which is proper, or rather which is proper convention? I see both as accomplishing the same task, but I've only ever used the latter, which is prevelant in most of the examples I've seen.

Thanks for your time, all!
