mainwindow.cpp

一大堆的qt程序,在qte2.3.7下全部可以很好地运行

#include "mainwindow.h"

MainWindow::MainWindow(QWidget *parent,const char *name)
		:QMainWindow(parent,name)
{
	setCaption("dialog");
	setBackgroundColor(white);

	QPopupMenu *option = new QPopupMenu;
	option->insertItem("&Choose background color",
		this,SLOT(chooseBackgroundColor()));

	QMenuBar *menu = new QMenuBar(this);
	menu->insertItem("&Option",option);
}

void MainWindow::chooseBackgroundColor()
{
	ColorDialog *d = new ColorDialog(this,"NULL",TRUE);
	
	d->exec();
	
	setBackgroundColor(d->color());

	delete d;
}
