I am writing a program which merges data from several sources into a spreadsheet. If the data for a cell is different from different sources, a human needs to choose the best one, so I want it to be obvious which cells need to be reviewed.
Not displaying the arrow when the data for the Combobox.set() has 0 or one item seems a good way, but I don't understand ttk styles and layouts well enough to do it.
I found a way to get the effect I want. I create both a Label and a Combobox at the same location and use .lift() to put the one I want on top.
How to create a custom tkinter Combobox with no arrow if there are 0 or 1 items?
