MinDevkit UI Objects: Setting JBOX flags and accessing paint methods?

Hi All,

I'd like to create some UI Objects that integrate with a C++ library. Min Devkit seems to be the tool for the job, but it's support for UI Objects seems limited. After doing some digging into how UI Objects are handled in Max SDK, I have a few questions:

The Min Devkit docs say the UI object has to inherit from the ui_operator class. Digging into this class template, I can see how it is handling most of the initialization required to set up a UI Object in Max SDK.

However, when it comes to setting the JBOX flags, a handful of flags are active and the rest, like JBOX_TEXTFIELD or JBOX_HILITE, for example, are commented out. Is there any way to override this and set my own flags? I tried modifying the ui_operator class definition in c74_min_operator_ui.h and was able to generate a whole bunch of errors, but nothing that would compile and work.

Similarly, how does the paint method work in Min? I looks like c74_min_graphics.h wraps many of the functions in the original jgraphics.h, but is this a complete replacement?

I understand that it's possible to call c74::max functions from within Min, but it gets a little confusing when Min is wrapping some of the relevant functions, but not all of them. Especially when it comes to the object setup. As a novice/intermediate programmer, I still get a bit confused by all of MINs macros and templates, and I'm not sure how/where to override them.

The Min documentation gives a list of messages ui_operator can respond to. This appears to be only a subset of the messages that are actually available in Max. Is this intended to be partial list? If so, how to find information on rest of them? Or is UI functionality only partially implemented in Min?

If I have to, I can build my UI object with Max SDK, and then pass values to and from a different object made in Min to access my C++ library. But it would be better if this could all be one object.

Thanks for any guidance here!
