Well, I've bodged it. The problems:
2- The reason the style was being ignored was that you can't just create a ChStyle and expect it to work, it needs to registered properly with Upp. This is normally done by the CH_STYLE macro, but you can also do it by copying an existing ChStyle before altering it. It may also be possible to use ChRegisterStyle__ directly.

	if (s.IsLoading())
		d = Button::StyleNormal(); // Make sure style is initialised
}


Thanks, that solved it! Not I can edit the styles again. I had no idea about the need to register styles. Just when I thought that Chameleon is done with it's surprises.

Personally I would avoid supporting saving themes, and just create a sensible file format than can be edited externally.


A more sensible format would be better than raw serializing, but I don't really know what to use. A ZIP with PNGs and a XML comes to mind, but that is a little too much work for my current needs. Maybe if some day we'll want official explicit theme support, I'll rewrite the thing to be a much nicer solution. Right now I'll focus on theming Toolbar and then get a preview out with code, which I'll show to the author of the original theme also, so he can warn me if I've completely butchered the look Razz.

There is a bit more bodging with StringStreams because for some reason PNGRaster and PNGEncoder are slightly incompatible.


What do you mean by that?
