Only the first defined shortcut works. Why?

Qt Code:
  1. QShortcut* shortcut1 = new QShortcut(QKeySequence(ButtonKeyDefines::QKEY_SOFTBUTTON_LEFT, ButtonKeyDefines::QKEY_SOFTBUTTON_RIGHT), pTableWidget);
  2. connect(shortcut1, SIGNAL(activated()), this, SLOT(shortCutMotorTune()));
  3.  
  4. QShortcut* shortcut2 = new QShortcut(QKeySequence(ButtonKeyDefines::QKEY_LEFT, ButtonKeyDefines::QKEY_RIGHT), pTableWidget);
  5. connect(shortcut2, SIGNAL(activated()), this, SLOT(shortCutSystemInformation()));
