how to create window that opened when close main window??

[Abeer]

Do you need something like this?

#include <QtGui>
int main (int argc, char** argv) {
    QApplication ap(argc, argv);
 
    QWidget *window1 = new QWidget(0);
    QWidget *window2 = new QWidget(0);
 
    QPushButton *button = new QPushButton("Open second Window", window1);
 
    window1->show();
 
    QObject::connect(button, SIGNAL(clicked()), window2, SLOT(show()));
 
    return  ap.exec();
}

#include <QtGui>
int main (int argc, char** argv) {
    QApplication ap(argc, argv);

    QWidget *window1 = new QWidget(0);
    QWidget *window2 = new QWidget(0);

    QPushButton *button = new QPushButton("Open second Window", window1);

    window1->show();

    QObject::connect(button, SIGNAL(clicked()), window2, SLOT(show()));

    return  ap.exec();
}

To copy to clipboard, switch view to plain text mode
