Hi community,

I have developed a tkinter GUI component, Python v3.7. It runs very well in Linux but seeing a huge performance impact in Windows 10. While in Linux an almost real-time performance is achieved, in Windows it is slow to an unusable level. The code is somewhat stripped down from the original, but the performance difference is the same anyway. The columns can be resized by clicking on the column border and dragging it. Resizing works only for the top row (but it resizes the entire column). In this demo, all bindings are avoided to exclude influence on the component performance and thus not included. If you resize the window (i.e., if you maximize it), you must call the function table.fit() from IDLE shell. Does anyone know where is this huge difference in performance coming from? Can anything be done about it? For reasons explained by Steve, please send this instead to python-list https://mail.python.org/mailman/listinfo/python-list To access python-list as a newsgroup, skip comp.lang.python and use newsgroup gmane.comp.python.general at news.gmane.org. I will respond there after testing/verifying and perhaps searching bugs.python.org for a similar issue. ttk has Treeview, which can be configured as a table.
