Question

I have the following source code:

void Processmethod()
{

    QDialog *ProcessMessage = new QDialog;      
    Ui::DialogProcessMessage Dialog;            
    Dialog.setupUi(ProcessMessage);             
    ProcessMessage->setModal(true);
    ProcessMessage->setAttribute(Qt::WA_DeleteOnClose); 
    ProcessMessage->show();

    processmethodONE();  
    processmethodTWO();
    processmethodTHREE();                  
}

void processmethodONE()
{
    QString ProcessCommand = "w8 " + blablubli";            

    Prozess.setWorkingDirectory(Path);         //QProcess "Prozess" is globaly defined  
    Prozess.setStandardOutputFile(Path);       //in my class
    Prozess.start(ProcessCommand);


while(!Prozess.waitForFinished(2000))
   {
       qApp->processEvents();
       std::cerr << "Process running " << std::endl;
   }

QProcess::ExitStatus Status = Prozess.exitStatus(); 

if (Status == 0)
 {
   std::cout << "File created!" << std::endl;
 }
}

So, my prob is that the dialogs content is missing for some reason. In the dialog I have some text and one button. I just want to see that content when the dialog popsup and while the processes are running.Any solutions or ideas how to achieve this? greetings

Answer 1

I used now qApp->processEvents(); in the processes while loops. The dialogs content doesn’t appear instantly, but at least after about five – ten seconds, which is at least ok to me. greetings and thx for the support.
