    yes m_mainWindow has value.

    I try another thing into ShowDataRecoveryInformDialog Funcation.
    Instead of the passing parent as argument. I set the parent with help of setParent property it is work.

    Thank you for Help @mrrj

      in addition, I try like
      QDialog* dialog = OBJ_NAME(new QDialog(m_mainWindow, Qt::SplashScreen), "notes-dialog");
      It is also create the same issue.

      only setParent is work fine.

        Hi,

        Why not use this rather than m_mainWindow ?

          and you have like
          ShowDataRecoveryInformDialog::ShowDataRecoveryInformDialog(QWidget *parent) : QDialog (parent)

          in your dialog so you forward parent to base?

              Can you show your complete code for your MainWindow ?

              It looks like you are modifying the wrong file.

                m_mainWindow is my main Object, it is create the whole application on GUI side by calling createUI funcation.

                yes i was try to set the parent as main object.

                I make this change and code work perfectly fine. and got the output, which I want.

                void MainWindowUI::ShowDataRecoveryInformDialog() {
                QDialog dialog = new QDialog( );

                dialog->setWindowFlags(Qt::SplashScreen);
                dialog->setParent(m_mainWindow);

                auto dialogLay = new QVBoxLayout(dialog);
                dialogLay->addWidget(PBT("button 1"));
                dialogLay->addWidget(PBT("button 2"));
                dialog->exec();
                }

                                  In this case I got dialog box on top of the screen but it is make another issue

                                  dialog->exec(); is not work as per expectation. without responding the to Dialog user access the other page also.

                                  In other word, user can access both screen Main application as well as Dialog box. how to block access on other widget until get response from the user in dialog box?

                                    Hi
                                    Im not 100% sure Qt::SplashScreen is compatiple with Qt::Dialog flag

                                    Qt::SplashScreen 0x0000000e | Window Indicates that the window is a splash screen. This is the default type for QSplashScreen.

                                    Normally used with QSplashScreen widget.

                                      dialog->setWindowFlags(Qt::Dialog | Qt::SplashScreen);

                                          but why you need Qt::SplashScreen ?
                                          and modal dialog ?
                                          cant you just use the dialog ?
