They're completely different widgets which use (or at least closely approximate) the theming of OS-native widgets. The first "t" stands for "tile" which is the extension that introduced them. As of Tk 8.5 the tile extension is integrated into the core. > 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 > 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. Additionally, there are some widgets (like comboboxes) that are only available in ttk. One disadvantage is that they generally aren't as flexible if you want to set specific colors/fonts/etc. > If tkx is supposed to be a thin wrapper over Tcl/Tk, does that mean > there are different types of entry/button/radio widgets in Tcl/Tk? Yup. > Any answers to the other questions from the previous post (#2, 3, 4, > 7, 8, 9, 10)? For 2-4 I don't know offhand. Check the Tk documentation linked above. #7 (fill when resizing) is probably the result of not using -sticky (when using the grid geometry manager) or -expand and -fill (when using pack). Getting things to resize the way your used to applications behaving takes practice. For #8 (attaching scollbars to a listbox) I recommend using Tkx::Scrolled. It's a mega-widget (so "yes" to #9) to make it easy to add scrollbars to anything scrollable. Making a megawidget isn't all that hard. Tkx includes LabelFrame as a simple demo. I've made a few and put them on CPAN. (Tkx::Scrolled is on of them.) For #10 (scrollbars after resizing) it sounds like programmatic resizing isn't triggering the events to update scrollbars. You may need to do it explicitly. I'd have to dig through the code to be sure. -mjc
