My answer is based on one buried in the middle of some forums. It was a bit difficult to find that solution, but I liked it because it allows you to distribute your application as a single cross platform script. There’s no need to run it through py2app or anything similar, which would then leave … Read more
The height of your scrollbar didn’t match the buttons frame height because you did’t tell it to stick North and South .grid(…, sticky=’ns’) Then, the scrolling behavior you want to achieve is described here: Adding a Scrollbar to a group of widgets See also @martineau‘s answer for a more general object-oriented solution with 2D scrolling … Read more
cx_Freeze does this but creates a folder with lots of dependencies. py2exe now does this and, with the –bundle-files 0 option, creates just one EXE, which is probably the best solution to your question. UPDATE: After encountering third-party modules that py2exe had trouble “finding”, I’ve moved to pyinstaller as kotlet schabowy suggests below. Both have … Read more

For example: l = tk.Label(text=”hello, world”) … print(“the label is”, l.cget(“text”)) You can also treat the object as a dictionary, using the options as keys. Using the … Read more

@BryanOkley shared that one cannot change the color of an individual cell in ttk.Treeview. So I explored using tk.Canvas() and tk.Canvas.create_text() to create the illusion of changing the color of a selected cell in a ttk.Treeview() widget. I was fortunate to come by j08lue/ttkcalendar.py which had the same objective and I adapted from it. My … Read more

I believe you should not execute the main loop on a different thread. AFAIK, the main loop should be executed on the same thread that created the widget.
