Anyone Tried Multi-Threaded Direct2D Using Delphi?

[Steve Maughan 26]

Has anyone had any success using Direct2D with multiple threads (i.e. multiple threads attempting to draw to the canvas at the same time)?

 

It seems possible according to this link:

 

https://docs.microsoft.com/en-us/windows/desktop/direct2d/multi-threaded-direct2d-apps

 

But I can't find anything Delphi specific information. Any links or sample code appreciated.

 

Thanks - Steve

The Delphi code will look just like the C++ code. I don't think you draw on the canvas at the same time though, the examples show that a lock has to be used.
