Hello,

I have a WPF application where one of its controls is hosting a VTK window. I want to set the icon of the mouse cursor to any image I want (for example, a magnifying glass to represent a zoom action). I have tried to do this from WPF side but when I hover the VTK window the cursor icon changes to VTK default cursor. I have also tried to set a custom icon from VTK side, but it appears that I can only choose among a small set of predefined cursors. Do you know how can I set a custom cursor for VTK?

Thanks in advance!

Custom cursors can be used via the `vtkRenderWindow`:

```cpp
renWin->SetCursorFileName(cur_file);
renWin->SetCurrentCursor(VTK_CURSOR_CUSTOM);

```

See [TestCustomCursorShape](https://gitlab.kitware.com/vtk/vtk/-/blob/03e04467edcf032fb015741deace8d16a6ffdebe/Rendering/OpenGL2/Testing/Cxx/TestCustomCursorShape.cxx) for an example.

Which VTK version begins to support this? I can’t find VTK\_CURSOR\_CUSTOM inside vtk8.1.2.  
Thanks.

Looking at the git history, it seems like it was added in v9.1.0.
