How to close Message Box Window

[saurabh162]

Hello Developers,

I open Message Box window using following code and want to close it after user has pressed either yes or no button. Can you please inform me how can I do it.

void MainWindow::on_pushButton_clicked()
{
  
    QMessageBox::StandardButton reply = QMessageBox::question(this,
                                        "My Title", "This is my custom Message",
                                        QMessageBox::Yes | QMessageBox::No);
    if(reply == QMessageBox::Yes){
       // QApplication::quit();
        //QMessageBox::Close();
        qDebug() << "Yes is clicked";
    }
    else
    {

        qDebug() << "No is clicked";
    }

Thanks a lot :)

Hi,

The QMessageBox will be automatically closed when clicking on either of these buttons. Isn't that the case for you ?

Hello @SGaist

Thank you very much for your fast reply. I think it was closing but my main window was not refreshing fast due to which I could not see closing of Message Box.

In other words, I could see closing of Message box only after I have put some milliseconds delay (generated using single shot timer) before checking value of variable "reply" as given below.

void MainWindow::on_pushButton_clicked()
{
  
    QMessageBox::StandardButton reply = QMessageBox::question(this,
                                        "My Title", "This is my custom Message",
                                        QMessageBox::Yes | QMessageBox::No);
  DelayMilliseconds(200); 
   if(reply == QMessageBox::Yes){
       // QApplication::quit();
        //QMessageBox::Close();
        qDebug() << "Yes is clicked";
    }
    else
    {

        qDebug() << "No is clicked";
    }

Please explain me if I have made any mistake or not understanding it correctly.
Thanks a lot :)

What refreshing are you talking about ?

@SGaist

I think he meant, that if he uncomment the "QApplication::quit", he does not see the result of the MSG-Box, because the main program gets killed instantly. So he cant check the result (output) of the if-clause.
Which makes sence :)

You dont need any delay.
Just keep the code as it is. Just remove the "QApplication::quit" and the "QMessageBox::Close", as the MessageBox gets closed after ANY ButtonPress Event (YES, NO, CANCEL, SAVE...whatever...)
Your MessageBox behaves like it should.
