How to check the checkbox based on users selection from a message window.

[rookee]

Hello All,

I'm trying to make the checkBox status back to checked again if users selection is "NO" on the pop up message window. I also want to flash messages when the selection is done. Please help. Thanks in advance.

void MainWindow::on_checkBox_clicked()
{
 
    if(ui->checkBox->isChecked())
    {
        cbx=1;
        //Something 
 
    } if(!ui->checkBox->isChecked()){
        QMessageBox::StandardButton reply;
        reply = QMessageBox::question(this,"Test", "Do you want to stop logging?", QMessageBox::Yes|QMessageBox::No);	     
        if(reply==QMessageBox::Yes){
          // A message should flash saying "Logging is stopped"
            qDebug()<< "Logging is stopped";
            cbx=0;
 
        }else {
            qDebug()<<"Logging will continue";  
	   // A message should flash saying "Logging will continue" and Keep the checkBox status back to checked again.
 
        }
 
    }
 
}

void MainWindow::on_checkBox_clicked()
{

    if(ui->checkBox->isChecked())
    {
        cbx=1;
        //Something 

    } if(!ui->checkBox->isChecked()){
        QMessageBox::StandardButton reply;
        reply = QMessageBox::question(this,"Test", "Do you want to stop logging?", QMessageBox::Yes|QMessageBox::No);	     
        if(reply==QMessageBox::Yes){
          // A message should flash saying "Logging is stopped"
            qDebug()<< "Logging is stopped";
            cbx=0;

        }else {
            qDebug()<<"Logging will continue";  
	   // A message should flash saying "Logging will continue" and Keep the checkBox status back to checked again.
	            
        }

    }

}

Can someone help me understand what qDebug statements are used for. The following is what I read on the Qt website. I couldn't get it, if someone can explain it little more detailed I would really appreciate it. Can I use qDebug to flash the messages that I want to.

The QDebug class provides an output stream for debugging information.
QDebug is used whenever the developer needs to write out debugging or tracing information to a device, file, string or console.

QDebug is used to print debug messages. These messages are not meant for the user but only for the developer.

To flash a message on the screen you can use:

• QMessageBox
• QErrorMessage
• QDialog

These options display a message and expect the user to click "OK".
If you want to "flash" the message and hide it automatically you can use a QTimer with the above options.

When I uncheck the checkbox I get the popup window but when I select "NO" on the popup window I want to set the checkBox status back to checked. How can I achieve that?

else {
qDebug()<<"Logging will continue";
ui->checkBox->setChecked(true);
}

else {
qDebug()<<"Logging will continue";
ui->checkBox->setChecked(true);
}
