Really it is all just core Tk in 8.5+, which Tkx binds too. If Perl/Tk were to update itself, it would get both as well. They are complementary widgets. The Ttk widgets tie strongly to native theming and drawing, while the classic Tk widgets are all owner (Tk) drawn and you get full control over them. A few classic Tk widgets (such as text and canvas) don't really have native equivalents and thus aren't in Ttk. >>> If I want to find help on these widgets, where do I look? >> >> Under the "Themed Widgets" section of the Tk documentation: >> >> http://docs.activestate.com/activetcl/8.5/tcl/tk_contents.htm > > But, if I look in the documentation, under "ttk_entry", for example, it > has "style" under "STANDARD OPTIONS", and if I click on "style" I'm > taken to a page where it says "standard options supported by widgets". > One of the many "standard options" is "-background" which "Specifies the > normal background color to use when displaying the widget".

Is there a list of > standard options that aren't supported for a given widget? You can assume that font and color control have been removed, except for the ttk::label widget. It is possible to use styles (see ttk_intro for basics) to modify the visuals of themed widgets. For the entry, this would work like: http://paste.tclers.tk/506 Also make sure to read http://www.tkdocs.com/tutorial/styles.html. > Mixing ttk and non-ttk widgets is ok?

The classic widgets still exist to support extra functionality that isn't available in x-platform widget sets for theming. >>> Why is there a difference and what are the advantages and >>> disadvantages to one over the other? >> >> The primary advantage is that it allows you to create Tk apps >> that look like native applications.

Not sure what "native applications" means.

How about ppm?
