Hi everyone,<br><br>i have a Qt4 application and i use vtk to display a vtkpolydata. <br>I start a new QThread in order to do some heavy computations and within the thread i call a method of mainWindow which updates the data and the vtk window. <br>Of course it doesn't work because i access with no synchronization shared data. I think i should use mutexes but unfortunately iam not familiar.<br>Can anyone help me in order to fix this problem?<br> </body>
