That's what Aaron's post is all about: > http://abock.org/2007/07/02/suboptimal-theming-in-gtk/ I didn't mean is it possible with the current code, rather - would getting support for "conjoined" widgets provide a sufficient interface for drawing tree view headers. Whilst the widgets don't know about rounding, the application programmer is in a unique position to specify via some API or "hint" that widgets belong together. (I think this is much less the case in the button example posted actually though, that case would be a theme decision I believe). By specifying - either at the theme level, or widget implementation / application level, that a particular widget expects to be drawn closely against another one should be enough to control the spacings and corner rounding. At the application (or widget implementation) level, we might add a flag to a button which makes it expect to be packed tight against another widget. This would turn off rounding on those tightly packed sides. Perhaps this hinting could be a properly of the container widgets were being packed into. My question was... is this enough to do everything a tree-view header special-cases? I'm not familiar with that widget's code.
