Constructor & Destructor Documentation

◆ DRWContext() [1/2]

DRWContext::DRWContext	(	Mode	mode,
		Depsgraph *	depsgraph,
		GPUViewport *	viewport,
		const bContext *	C = nullptr,
		ARegion *	region = nullptr,
		View3D *	v3d = nullptr )

If viewport is not specified, DRWData will be considered temporary and discarded on exit. If C is nullptr, it means that the context is not associated with any UI or operator. If region is nullptr, it will be sourced from the context C or left as nullptr otherwise. If v3d is nullptr, it will be sourced from the context C or left as nullptr otherwise.
