Under "Paths and Symbols" I added my QT headers which are also displayed in the project explorer.

Within my header files, which include the QT headers, everything is fine so far (except little qt specific details like the macro Q_OBJECT is not known as well as "public slots:" and so on).

And how I can make Eclipse resolve those symbols from the included headers?

Did you add all possible include paths? Subfolders are not automatically included! Did you add the include paths to C and C++?

That is already an error. These macros should be resolved. Are the Qt includes marked as unresolved?

#include <QtGui>

I would suggest to create a linked folder in your Eclipse project that contains the Qt headers.

#include <QtGui>

class MainWindow : public QMainWindow //<- no warnings or errors from Eclipse!
{
	Q_OBJECT //<- Syntax error
public:
	MainWindow(QWidget * parent = 0, Qt::WindowFlags flags = 0); //<- Type 'Qt::WindowFlags' could not be resolved
	virtual ~MainWindow();

public slots: //<- Syntax error
};

#include "MainWindow.h"

MainWindow::MainWindow(QWidget * parent, Qt::WindowFlags flags) : QMainWindow(parent, flags) //<- Member declaration not found
{
    setWindowTitle(); //<- Could not be resolved
    setCentralWidget(); //<- Could not be resolved
}

#include <QtCore/QObject>
