App: Sequence Editor (a simplified one level Sequence editor)
Plan: Use a previous app to create the Sequence Editor
1) Command List with tab section
2) A List to hold the Sequence being created
3) Some button to Move command to Sequence List
4) create some simplified UUT(something to control with the sequence list)
Window layout
MainWindow
TopFrame(title and company labels)
Frame1(command list), LeftFrame(Sequence List),TopFrame (simulated UUT to test out sequence)

Notes
- Presentation: Sequence editor GUI with a simple UUT (Magnetic Crane and ball)
- Programming Language used: Python 3.9 in Spyder 5.4.3
- Presentation app: Microsoft’s PowerPoint
- Python and Tkinter are products of respective company
- Presentation shown to spark ideas of use.
- This presentation is not connected to or endorsed by any company.
- Use at your own risk.
- Tags: Python, Python3.9, Tkinter , Canvas ,GUI, List, Dictionary, StringVar, Calling, Event binding , ListSelect, Classes, Python Sequence Editor example. Magnetic Crane example, Listbox. radiobutton
- Future possibilities (currently in this demo there is no file save of the sequence or reading of a save sequence to keep the demo self contain to one file(the script) but in actual use most likely a “save sequence” and “get sequence” will need to be added. Maybe something for you to do if needed.
