私が持っているのはmain.cpp
:
#include "myclass.h"
#include <QApplication>
#include <QTextEdit>
#include <QtGui>
class Notepad : public QWidget {
Q_OBJECT
public:
Notepad();
private slots:
void quit();
private:
QTextEdit *textEdit;
QPushButton *quitButton;
};
Notepad::Notepad()
{
textEdit = new QTextEdit();
quitButton = new QPushButton(tr("Quit"));
connect(quitButton, SIGNAL(clicked()), this, SLOT(quit()));
QVBoxLayout *layout = new QVBoxLayout;
layout->addWidget(textEdit);
layout->addWidget(quitButton);
setLayout(layout);
setWindowTitle(tr("Notepad"));
}
void Notepad::quit()
{
QMessageBox messageBox;
messageBox.setWindowTitle(tr("Notepad"));
messageBox.setText(tr("Do you really want to quit?"));
messageBox.setStandardButtons(QMessageBox::Yes | QMessageBox::No);
messageBox.setDefaultButton(QMessageBox::No);
if(messageBox.exec() == QMessageBox::Yes)
qApp->quit();
}
int main(int argc, char *argv[])
{
QApplication app(argc, argv);
return app.exec();
}

私はVSとQtが初めてです。これに対する解決策を見つけたいと思っています。ありがとう。
