GTK+ Issues

During my ongoing work on an SVG based theme to be realized with the gtk-css-engine I became aware of a number of shortcomings in GTK+.

There’s no Prelight on menus and tabs, making them feel like dead space. There’s an old bug report with patch for this, but it started out as being specifically for the Windows port:

No Active (depressed) state for entries. This is admittedly controversial:

Treating the parts of a SpinButton like separate widgets works against drawing arrows “inside” a SpinButton. Also the focus indication isn’t drawn around the whole widget like it should be, for this reason:

There shouldn’t be focus indication on only the current tab of a Notebook:

There should be support for drawing the sides of tabs differently depending on whether they line up with the page or not:
