you don't need to move the view manager to SimGear to accomplish this - like I mentioned previously, the correct way to access FG-level subsystems via the Canvas system is to review/extend the FGCanvasSystemAdapter to expose the corresponding APIs. | |||
I actually posted code snippets that illustrate how to do this, for example in the 3D model loader, specifically look for the FGCanvasSystemAdapter changes in both $FG_SRC and $SG_SRC | |||
There is step by step instructions which can be found here: [[Howto:Extending Canvas to support rendering 3D models#Extending FGCanvasSystemAdapter]] | |||
In other words: Any API that you need to access from the Canvas system would need a correspondinger "getter" added to retrieve the handle from the FG host application. | |||
And that should be reflected in the header file | |||
But the implementation would reside in $FG_SRC/Canvas/FGCanvasSystemAdapter.cxx - the SimGear code would only have a copy of the corresponding header file.<ref>{{cite web | |||
