Help about a problem on the tray...

[Bong.Da.City]

I have an application that when you minimize it it goes to tray.. If you right click on the icon on the tray it show a menu.. See screenshot.



So when i press the About a QMessageBox is been shown.. See screenshot.



The problem is that when i press ok or close the QmessageBox the application closes.. I want to go back to the tray.. How can i do this?

This is what happens when you press About

QMessageBox msgBox;
    msgBox.setText("<b>This is my <big>Clock</big> application<b>.");
    msgBox.setInformativeText("If you like it, visit my <a href=http://www.qtforum.org>webpage</a>!");
    msgBox.setWindowTitle("Clock v0.1 by bong.da.city!");
    //set the icon of the message box to a custom pixmap of size 64x64
    msgBox.setIconPixmap(QIcon(":/new/clock/clock.png").pixmap(QSize(64,64)));
    msgBox.setWindowIcon(QIcon(":/new/clock/clock.png"));
    msgBox.exec();

QMessageBox msgBox;
    msgBox.setText("<b>This is my <big>Clock</big> application<b>.");
    msgBox.setInformativeText("If you like it, visit my <a href=http://www.qtforum.org>webpage</a>!");
    msgBox.setWindowTitle("Clock v0.1 by bong.da.city!");
    //set the icon of the message box to a custom pixmap of size 64x64
    msgBox.setIconPixmap(QIcon(":/new/clock/clock.png").pixmap(QSize(64,64)));
    msgBox.setWindowIcon(QIcon(":/new/clock/clock.png"));
    msgBox.exec();

I am only guessing here, but you may need to connect the QMessageBox::buttonClicked() signal to a custom slot.

Post some code telling us what the program does after you click the OK button on the dialog and the exec() call returns. The snippet above is not useful.

Xmm .. Yes i also believe that.. But first i do not how to go to the slot of this button because it is a QMessageBox ( A friend hat created this application )
Do you want to give you a link of the project?

Shouldn't i probably minimize it somehow and then show the tray icon? Look what i had think...

void roloi::showAbout()
{
    QMessageBox msgBox;
    msgBox.setText("<b>This is my <big>Clock</big> application<b>.");
    msgBox.setInformativeText("If you like it, visit my <a href=http://www.qtforum.org>webpage</a>!");
    msgBox.setWindowTitle("Clock v0.1 by bong.da.city!");
    //set the icon of the message box to a custom pixmap of size 64x64
    msgBox.setIconPixmap(QIcon(":/new/clock/clock.png").pixmap(QSize(64,64)));
    msgBox.setWindowIcon(QIcon(":/new/clock/clock.png"));
    msgBox.exec();
 
    Minimize Here!!!
    trayIcon->show();
    emit minimized();
}

void roloi::showAbout()
