[Qt-interest] Intercept Esc and Return/Enter keys in a QComboBox line edit

[chandrasekar wagmare]

simple i also crossed this problem ...
      this because of using dialog as parent .. use this ..
  QAction *quitAction = new QAction(tr(""), this);
        quitAction->setShortcut(QKeySequence(Qt::Key_Escape));
        connect(quitAction, SIGNAL(triggered()), this, SLOT(goMainPage()));
        addAction(quitAction);

        QAction *quit2Action = new QAction(tr("E&xit"), this);
        quit2Action->setShortcut(tr("Ctrl+Q"));
        connect(quit2Action, SIGNAL(triggered()), this, SLOT(askQuit()));
        addAction(quit2Action);

or else
          reimplement QCloseEvent to certain condition ...
