i found out this situation cause. i modifed qtitan code belows, then i solved my problem but i got another problem.
another problem is when mouse double click, i got twice click event( click, doub click event ) .
so, i suggest you to modify below qtitan code that before run (if (doubleclick ) return, distinguish mouse click row index based on mouse click pos.

GraphicControl::mouserPressEvent( QmouseEvent* event )
{
if( !m_rootGP )
return;

#if (QT_VERSION >= QT_VERSION_CHECK(5, 0, 0))
ulong doubleClickInterval = static_cast<ulong>(qApp->styleHints()->mouseDoubleClickInterval());
bool doubleClick = event->timestamp() - m_mousePressTime < doubleClickInterval /*&& button == mousePressButton*/;
m_mousePressTime = event->timestamp();
m_mousePressButton = event->button();
m_pressPos = event->globalPos();
// if( doubleClick )
// {
// return;
// }
#endif

This code was our fix for an issue in Qt. In Qt5.3 bug was fixed by this commit - qt.gitorious.org/qt/scitools-qtbase/comm...2229627f36d60168f0e2
So please add these lines to code, fix will be added to the build of QtitanDataGrid to the end of this week.
void GraphicControl::mousePressEvent(QMouseEvent *event)
 {
    if (!m_rootGP)
        return;

#if (QT_VERSION >= QT_VERSION_CHECK(5, 0, 0))
#if (QT_VERSION >= QT_VERSION_CHECK(5, 3, 0))
    bool doubleClick = event->flags().testFlag(Qt::MouseEventCreatedDoubleClick);
#else
    ulong doubleClickInterval = static_cast<ulong>(qApp->styleHints()->mouseDoubleClickInterval());
    bool doubleClick = event->timestamp() - m_mousePressTime < doubleClickInterval /*&& button == mousePressButton*/;
#endif    
    m_mousePressTime = event->timestamp();
    m_mousePressButton = event->button();
    m_pressPos = event->globalPos();

    if (doubleClick)
        return;
#endif
