Thanks for support you are right it was a problem of modeless

I have Just added as per Example above: 

 findDialog->setModel(false);
 findDialog->show();

Before Show I have added setModel(false); and its then working like a charm !!!

Thanks and Regards Praveen Kumar

So, you don't want to have your GUI blocked while dialog is open, right?

Use a modeless dialog:

void EditorWindow::find()
{
    if (!findDialog) {
        findDialog = new FindDialog(this);
        connect(findDialog, SIGNAL(findNext()), this, SLOT(findNext()));
    }

    findDialog->show();
    findDialog->raise();
    findDialog->activateWindow();
}

Note: The code was taken from the Qt documentation. Notice that we are not using a QDialog::exec() method but just QWidget::show().
