Hello. I am trying to study how to put a GUI on a program using this//www.sinclairbody.com/doc/en/PythonAPI/exam...amming-gui. I am testing it on a weld simulation, but it is not working. I would appreciate the help so I can better understand how to use Pythong API on RoboDK.

When I run the program, I get this and I don't understand it:

Code:

PS C:\Users\Andrew L. Nguyen> & C:/RoboDK/Python37/python.exe "c:/Users/Andrew L. Nguyen/AppData/Local/Temp/Prog2_4.py"
Invalid item provided: The item identifier provided is not valid or it does not exist.Exception in Tkinter callback
Traceback (most recent call last):

self.link._check_status()

raise Exception(self.LAST_STATUS_MESSAGE)
Exception: Invalid item provided: The item identifier provided is not valid or it does not exist.

This is the offline programming GUI example from RoboDK that I am experimenting:

Code:

# This example shows how RoboDK and the Python GUI tkinter can display graphical user interface to customize program generation according to certain parameters
# This example is an improvement of the weld Hexagon
