I am using Visual Studio 2015 Enterprise edition, CMake 3.11.2, and vtk 9.0. Everything was compiled as 32bit application.</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Question #1: </p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>In order to integrate QVTKOpenGLWidget into Qt Designer, I had to copy QVTKWidgetPlugin.dll/pdb into a path that’s accessible to Qt Designer. There is no QVTKOpenGLWidgetPlugin.* as far as I can tell. In Qt Designer, I do have access to QVTKWidget but not QVTKOpenGLWidget.</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>The generated .ui file hence contained QVTKWidget and I had to manually edit the .ui file to replace QVTKWidget with QVTKOpenGLWidget.</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Is this the correct way of doing things? Is manual editing required?</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Question #2:</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>I tried to follow VTK/Qt examples such as <a href="https://lorensen.github.io/VTKExamples/site/Cxx/Qt/ShareCameraQt/">https://lorensen.github.io/VTKExamples/site/Cxx/Qt/ShareCameraQt/</a>. Suppose I have generated a Qt app based on QMainWindow, with a QWidget as the centralWidget and a QVTKOpenGLWidget on top of the centralWidget (as seen on the example above). This was accomplished using Qt Designer and the resulting .ui file resembles to the example above.</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>While it works, I am having difficulties in setting up the size policy. In short, no matter what sizePolicy I set to both (or either) the QWidget and QVTKOpenGLWidget, their sizes are fixed. If I maximize the window, the QVTKOpenGLWidget does not maximize.</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Can anyone shed some light into this issue? I can attach the .ui file if it is appropriate.</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Any help is very much appreciated,</p><p class=MsoNormal><span style='color:#212121'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-family:"Arial",sans-serif;color:#212121'>--</span><span style='color:#212121'><o:p></o:p></span></p><p class=MsoNormal><span style='font-family:"Arial",sans-serif;color:#212121'>Elvis C.S.
