Reading A File Without Block Main Thead In Gui

In my first attempt, I tried, failed, learned, and came back with the following attempt. I have a text file with the names parsed with commas that looks like this: Ann Marie,Smith

Solution 1:

The for-loop in textfilemanage() waits until the thread finishes so the different thread is useless in the code.

Instead:

Create the empty combobox in __init__ (needed for layouting) and assign it to self.combo

In textfilemanage() start the thread but don't wait for it.

In read_employees() replace the final return statement by

wx.CallAfter(self.combo.Append, emp_list)

or

wx.CallAfter(self.combo.AppendItems, emp_list)

(it depends on the wxPython version which variant is accepted)
