[SOLVED] Where is DG::Image defined?

Anonymous — Thu, 13 Jul 2023 13:49:29 GMT

In the docs, the image parameter for DGSetItemImage is a void * which resolves to a platform-dependent bitmap handle (HBITMAP on Win). But the actual header defines this as a DG::Image class (namespace DG). It's forward-declared for the parameter reference but there is no actual definition for the class in the API Dev Kit (using 18.3006).

Basically, I just want to draw a custom image in an area of a modeless dialog.

Can anyone point me in the right direction?

Thanks.

UPDATE: I'm now trying DG::ModelessDialog. Perhaps this is a later API as all required defs are there

The DG::Image class is defined in DGUtility.hpp
You would normally construct one by passing the resource module and image resource ID
