TNA_Image seems to be currently unimplemented. The tag is set but the class doesn't do anything with it, apparently.

If that's the case the documentation needs updating at the very least.

No problem, thanks for confirming! Looks like we need somebody from the OS team to weigh in/fix.

I did try just TNA_Image first, before trying both together.

My most recent thought is that maybe it only supports basic Images, not BOOPSI images, but that would be a bit weird given it's part of a BOOPSI class set.

Does this work? I've set TNA_Image to both a label.image and a bitmap.image object on a clicktab node, and it just ignores it and shows TNA_Text (if specified) or nothing. I've tried the same thing on both OS4.1FE update 3 and OS3.2.3, and it doesn't appear to work on either.

I'm guessing this has ...

I did wonder if it wasn't copied, so I tried making it global - but by that point I'd already added the line pattern and width commands which were making it invisible!

I've got it working now, thanks.

Sounds like the docs need updating though.

How does drawlist.image work? I'm trying to create a custom drawlist image with the following code:

struct DrawList opendrawer[] = {
{DLST_LINESIZE, 0, 0, 0, 0, 0xff},
{DLST_LINEPAT, 0, 0, 0, 0, 0xff},

{DLST_LINE, 90, 60, 90, 90, 1},
{DLST_LINE, 90, 90, 10, 90, 1},
{DLST_LINE, 10, 90, 10 ...

The Checkbox ReAction gadget could benefit from a "partially selected state".
Don't know if it helps you but the tickbox.gadget from the Enhancer class set has this feature. I know because I implemented it :-) I'll be happy to add it to the system checkbox as soon as the lawsuit is over ...

The Checkbox ReAction gadget could benefit from a "partially selected state". This is the state used to indicate that the children have some, but not all, items selected. It is usually depicted in other operating systems as a dot or square. The user themselves won't be able to pick this, it will ...

nonvolatile.library also theoretically lets you save/load CD32 game states from a drawer in SYS: (I think it's libs:nvram or something like that), however I'm not convinced this functionality is in the OS4 version as when I tried it many years ago it didn't appear to work.

That's interesting, the OS4 version does now have some functions as you mention. The information given about version numbers is not accurate/complete though:

OS3.5 BB1 is V44.3 and OS3.5 BB2 is V44.4. There is also nothing about OS3.9 BB3&4, OS3.1.4(.1), or OS3.2(.1). I can give a list of version ...
