Firemonkey Form in Dock Panel?

Craig ThomsonCraig Thomson
in LMD-Tools
There exists the following which I have found useful to mix Firemonkey with VCL:

https://parnassus.co/tfiremonkeycontainer-a-vcl-control-for-mixing-vcl-and-fmx/

The trouble is it feels a little clunky (undocking a tab makes the FMX form / content disappear) and performance becomes rather slow when the Window is made bigger.

Has anyone successfully mixed FMX with the LMD docking and can provide some useful tips?

I need to use VCL for the docking, but I also need FMX as I want to render 3D content in the dock panel.

Thanks

    So the performance issue may not actually be a problem with the docking as I tested in a new Firemonkey project a TColorPanel aligned to client and it still causes a slowdown (I only chose that control for a test).

    I'm left with two options now I think,

    Option 1 - prevent tabs been undocked
    Option 2 - find a solution that still allows undocking without losing the content

    Here you can see the content (firemonkey form) is lost when undocked.

    Most probably, the mentioned library does not respect the fact that VCL controls can (temporary) exist without real window handle (or parent window handle), and, as well, can change parent window and be ready to recreate its own handle at any time. So, this is a violation of implicit VCL protocol.
