View source for Inside Qt for Symbian QApplication

{{Outdated|reason=The Symbian platform is no longer supported.}}
{{Cleanup | reason=Auto-imported from ExpressionEngine.}}

== How is the application started? ==
We all know that the application is started after we create a QApplication like the following:
<code>QApplication app(argv, args);<code>
wow, thats really much easier than symbian, you know, you have to know so much about the AVKON application framework when using Symbian C++, and for now, all you have to know is creating a QApplication. But Im the person who always wanna know more, so lets look inside the source code.

First, let us take a look at QApplication's ctor:
</code>QApplication::QApplication(int &argc, char **argv)
 : QCoreApplication(*new QApplicationPrivate(argc, argv, GuiClient) //create a QApplicationPrivate
{
 Q_D(QApplication); //just Q_D macro, so we can just the following d
 d->construct(); //call d's construct()
}<code>

Line 2 creates a QApplicationPrivate with argc, argv and GuiClient. Here GuiClient is an enum, and we use it to tell QCoreApplication what type of application we wanna create.
