Browsing the TkDocs website, it looks like Tk has come a long way in the "native look and feel" department. But looking at some of these screenshots, it seems to be let down in Linux. If you scroll down that page, you'll see a Mac screenshot that looks exactly like Mac, a Windows XP screenshot that looks exactly like Windows XP, and a Linux screenshot that looks like ... well Windows 98 (or Windows XP with classic style).
I know Linux doesn't really have a "native look and feel", since every toolkit does its own styling. But I'm wondering if there is any way to style Tk so it looks like either GTK or Qt (preferably Gtk), so it would blend in to most other apps on the Linux desktop.
What about Windows Vista/7? I haven't seen any Tk screenshots on those platforms.
