Restoring the C++Builder visual component from VTK 7 and 8

Development

Hello. VTK versions 7 and 8 shipped with a visual component/widget for C++Builder (eg: VTK-7.1.1\Examples\GUI\Win32\vtkBorland\Package). This is not present in VTK 9.

Is it possible to restore this please?

I filed an issue request but it was closed with a comment about CMake. C++Builder supports CMake, including for component packages. We are currently trying to contribute toolchain support back to CMake itself.

I would simply make a pull request myself – we’ve had several bug reports filed by customers about this – but it takes time to get approval to contribute to external code bases :frowning: I apologise for that. I can absolutely help in any way short of directly making a pull request with code I write until I get that approval. FWIW, the existing component from v8 should work unless VTK itself has made API changes. On the CB side we are 100% backwards compatible in this area.

The VTK CMake API changed, but it probably shouldn’t be too hard to port the relevant bits from the example. The examples themselves have changed a bit too. I don’t think anyone here has access to test any such support here, but if you’d like to submit an MR with support that works as you need, I think that would be acceptable.

Just an FYI for anyone reading this, here is a link to the code:

Even though it was included with VTK 7 and 8, my understanding is that it has been unmaintained since VTK 5.
