#83171 — Re: Python Tk Tix GUI documentation & builder overview and tips

Hi,

I have had issues running Tix on python 2.7.6 and 3.4.2:

More details on the issue here.

http://stackoverflow.com/questions/27751923/tix-widgets-installation-issue

Has anyone had similar issues with Tix?

Thanks and Happy New Year.

The current doc is wrong in any case.  I opened

Tix is a compiled extension, so this tix8.4.3.dll is needed as well as a 
couple of .tcl file including pkgIndex.tcl, which makes the package 
available to the Tcl interpreter. tix*.dll was never part of tk*.dll.

Note that Tix is LEGACY. There are much better options for its widgets 
available that are based on ttk. Just to try, I compiled Tix under OSX 
for my Tk8.6.3 and ran the widget demos.

Instead of

* Hierarchical Listbox use ttk::treeview, tablelist_tile or tkTreeCtrl, 
with increasing order of capabilities and install complexity

* TList: I think tkTreeCtrl can do it, never have used this layout

* CheckList: tablelist can be used with an editable field

* Grid widget: use tkTable

* NoteBook, PanedWindow, ComboBox, LabelFrame -> ttk::notebook, 
ttk::panedwindow, ttk::combobox, ttk::labelframe

* Balloon: tcllib::tooltip

Not to mention that the Tix widgets are extremely ugly, while the 
widgets from ttk have a near-native look and feel.

Caveat emptor: I've never used Tix, so this is just my impression as an 
experienced Tk programmer from running the widget demo

I copied parts of this response with additional comments in a new 
tracker post.
