I'm trying to create a custom layout for a ttk::entry widget, but the widget's background cannot be configured on Aqua. Instead of having a matching background with the surrounding widgets/toplevel, the entry displays the default themed background of a ttk::frame. See http://www.codebykevin.com/pic.png. Code below was tested in the Tcl chatroom by others and they confirmed it works fine under Linux: hence I think it's a Tk-Aqua bug.

    (thought this had been mentioned before, apparently not) --

    Not all elements support the "-background" option; in fact not even all "background" elements support the "-background" option. (In particular: the Aqua theme "background" element has no options at all, it just calls HIThemeSetFill(kThemeBrushXYZZY) and CGContextFillRect()).

    To make this work under OSX, construct a layout that includes an element that supports the features you need. You can import one from a different theme (see: [ttk::style element create _ from ...]) or create an image element (see: [ttk::style element create _ image ...]).
