I have now created an independent example: (Sorry it does not use an .ui file)
main.cpp
#include <qt/qapplication.h>
#include "MainWindow.h"
int main(int argc, char** argv)
{
MainWindow mainWindow;
mainWindow.show();
return app.exec();
}
#include <qt/qapplication.h>
#include "MainWindow.h"
int main(int argc, char** argv)
{
QApplication app( argc, argv );
MainWindow mainWindow;
mainWindow.show();
return app.exec();
}
To copy to clipboard, switch view to plain text mode
MainWindow.h
#ifndef MAINWINDOW_H_
#define MAINWINDOW_H_
#include <QtGui/QApplication>
#include <QtGui/QGridLayout>

MainWindow->resize(500, 500);
m_centralwidget
= new QWidget(MainWindow

sizePolicy.setHorizontalStretch(0);
sizePolicy.setVerticalStretch(0);
m_centralwidget->setSizePolicy(sizePolicy);
gridLayout

} // setupUi

In this example nothing is resized if I resize the dialog.
