Can't build official Qt tut code using Qt Creator

[Jaggid1x]

I can't build this simple code at the very beginning of the Qt tutorial

@
1 #include <QApplication>
2 #include <QTextEdit>
3
4 int main(int argv, char **args)
5 {
6 QApplication app(argv, args);
7
8 QTextEdit textEdit;
9 textEdit.show();
10
11 return app.exec();
12 }
@

from here: http://doc.qt.nokia.com/4.7/gettingstartedqt.html

It tells me
QApplication.h No such file or directory
QTextEdit.h No such file or directory

I can only imagine there's something wrong with my settings, but I'm using Qt Creator and haven't messed with anything.

It looks like you called
@qmake main.cpp@

use qmake for the .pro file to get a Makefile
use make to run the Makefile
This will give you an executable for your platform.

Read the relevant part of the link you specified again :-)

Can you paste your .pro -file?
It should look something like:
@
TEMPLATE = app
TARGET =
SOURCES += main.cpp
@

Also which version of Qt Creator are you using? And Qt?

Did you copy those line numbers to file or just some paste error?

Edit:
Yeah OK faster reply was right =)
Nothing wrong with code

@#include <QTextEdit>@
angle-bracket. That means that g++ will be called with -I flag.
For example, set of instructions, produced by qt creator:
@g++ -c -g -frtti -fexceptions -mthreads -Wall -DUNICODE -DQT_LARGEFILE_SUPPORT -DQT_DLL -DQT_GUI_LIB -DQT_CORE_LIB -DQT_THREAD_SUPPORT -DQT_NEEDS_QMAIN -I"..\qt\include\QtCore" -I"..\qt\include\QtGui" -I"..\qt\include" -I"..\qt\include\ActiveQt" -I"debug" -I"." -I"..\test" -I"." -I"..\qt\mkspecs\win32-g++" -o debug\mainwindow.o ..\test\mainwindow.cpp @
that was how include works under the hood. Why?

I'm sure that you

1. haven't some qt libs (or all - installed only creator, not libs)
2. have wrong qtreator settings (a wrong QT PATH) -> it's searching for includes in wrong directory.

I'm guessing it's #2 since I found QApplication in the SDK folders, but where do I set the lib directory? This is the only window I found that seems in any way associated with a lib directory:

Okay, I got it. Googled a bit to look for a way to add includes and libs onto Qt Creator. Didn't know you had to add them into the .pro file for each project =/ . Thanks for your help.
