I've been trying to add separator lines between rows in my grid. I tried using wx.Menu() with the AppendSeparator() method, however the wx grid can't add objects of type Menu. Is there any other way?
This is not supported by the grid widget. You could size a column or row such that it is skinnier than usual and change all the cells in that row or column to have a different background color. You might also be able to utilize a custom label renderer or cell renderer. See the wxPython demo for examples.
How do I add a separator in a grid in wxPython?
