Comment 92 for bug 195929

I don't want to speak for roc, but he may have confused the "style property" and the "widget property" when typing, at least, that's how I read it.

Anyway, "honors-transparent-bg-hint" makes no sense if it's the style property, which is used by the theme to ask gecko to ommit the background painting. On the contrary, it is a good name for the widget property, used by gecko to tell the theme it honored (or it can honor) the transparent bg hint.

As for the progressbar, you cannot just set the "I honor the style property" to true, if you don't really honor it, which means it has been added also to the progress bar class, and we effectively obey it.

Which brings be to the point that we probably should create a style property for a generic widget, if that's possible, and check for it every time we fill a background ourselves before calling the engine. Then we could set the "honors-transparent-bg-hint" on every of our widgets in setup_widget_prototype (and manually when we don't use it).

roc, what do you think about that ?

One last remark, I'd like to have a review by Benjamin, and a review by me before the superreview from Robert. Alternatively, I takeover the bug since I have ideas for it, and then ask for r to Benjamin and Michael, and sr from roc.
