Here is the code that doesn't work:
main.cpp
#include <QApplication>
#include "mainwindow.h"
int main(int argc, char *argv[])
{
QApplication app(argc, argv);
MainWindow *MainForm = new MainWindow;
MainForm->show();
return app.exec();
}
mainwindow.h
#ifndef MAINWINDOW_H
#define MAINWINDOW_H
#include <QMainWindow>
#include "mainwindow_ui.h"
class MainWindow : public QMainWindow
{
Q_OBJECT
public:
MainWindow(QWidget * parent = 0);
private:
Ui::MainWindow ui;
};
#endif
mainwindow.cpp
#include <QtGui>
#include "mainwindow.h"
MainWindow::MainWindow(QWidget *parent)
: QMainWindow(parent, 0)
{
ui.setupUi(this);
}
mainwindow.ui
