Learning qt5 and qml on android tablet with c4 droid

[DaReal_ApacheOmega]

Hello!
I’m using C4droid and learning qt for the first time. I just want to know if:
A. Could I still use qt 3 or qt 4 gui and programming examples? The reason I ask because I typed in this basic of all codes example
[Code]
#include <qapplication.h>
#include <qlabel>

int main(int argc, char *argv[])
{
QApplication app(argc, argv);
QLabel *label = new QLabel("Hello Qt!", 0);
app.setMainWidget(label);
label->show();
return app.exec();
}
[/Code]
And got this Message:

//No such file or directory #include <qapplication.h>

I even tryed to remove the dot h and still the same results

question B.

Where can I get all the examples on qt 5.3 Gui desidn and programming and also tutorials on how to intergrate c++ code with qml code also
Thank You
AO!

P.s. do I need to purchase the full version for all this?

Hi and welcome to devnet,

For your question A, use

@
#include <QApplication>
#include <QLabel>
@

Though the basics are the same, Qt 3 examples might contain classes long gone since Qt 4. However most Qt 4 example translate easily to Qt 5.

For question B, Qt's documentation and sources.

What purchase are you asking about ? c4droid ?

[DaReal_ApacheOmega]

For these two questions, you should rather contact the c4droid developer(s)
