Hi,
Does anyone have any idea why I am getting following error?
'mouseRelease' : is not a member of 'QTest'
I have include QTest still I am getting this error. Any hellp will be appreciated.
Kind regards,

Post the pertinent calling code please.

Following code gives me 'mouseRelease' : is not a member of 'QTest' error. I am using Qt 4.7 and VS2010.

QTest::mouseRelease(m_pCameraDisplayManager->m_pTreeViewList,Qt::LeftButton,QPoint(0,0));
