userdialog.cpp

qt实例 在qt2.3.7调试ok！没有在arm板测试！第3例

#include "userdialog.h"

userDialog::userDialog(QWidget *parent, const char *name):QWidget(parent, name)
{
	QPushButton *btn = new QPushButton("POPUP", this);
	btn->setGeometry(50, 20, 100, 40);
	connect(btn, SIGNAL(clicked()), this, SLOT(popupDialog()));
}

void userDialog::popupDialog()
{
	QDialog *dlg = new QDialog(0, "popup", FALSE);
	dlg->setCaption("A QDialog Window");

	QPushButton *btn = new QPushButton("POPDOWN", dlg);
	btn->setGeometry(50, 20, 100, 40);
	connect(btn, SIGNAL(clicked()), dlg, SLOT(accept()));

	dlg->show();
}

int main(int argc, char **argv)
{
	QApplication app(argc, argv);
	userDialog udlg;
	udlg.show();
	app.setMainWidget(&udlg);

	return(app.exec());
}
