Troubleshooting

These items may solve your problem. Please check those you've done by changing - [ ] to - [X]

• Searched main docs for your problem www.PySimpleGUI.org
• Looked for Demo Programs that are similar to your goal Demos.PySimpleGUI.org
• If not tkinter - looked for Demo Programs for specific port
• For non tkinter - Looked at readme for your specific port if not PySimpleGUI (Qt, WX, Remi)
• Run your program outside of your debugger (from a command line)
• Searched through Issues (open and closed) to see if already reported Issues.PySimpleGUI.org
• Tried using the PySimpleGUI.py file on GitHub. Your problem may have already been fixed but not released

Detailed Description

The Spin element's up/down buttons update their value as you keep them pressed - similar to RealTimeButton elements - and yet they don't seem to trigger any events like the RealTimeButtons; using enable_events=True only triggers once - and only once the click is released.

I searched for anyone else having a similar problem, but the only one I could find was from back when the up/down button didn't trigger at all.

Code To Duplicate

import PySimpleGUI as sg

endFrame = 0
endSpinF = 0

layout = [[
  sg.Spin(key='endSpinF',values=[i for i in range(0,1000)],initial_value=endFrame,size=(4,0),enable_events=True),
  sg.Text(endFrame,key='endFrame',size=(4,0))
]]

window = sg.Window('Spin Event Test',layout)

while True:
  event, values = window.read()

  if event == 'Exit' or event == sg.WIN_CLOSED:
    break

  elif event == 'endSpinF':
    last_endSpinF = endSpinF
    endSpinF = values['endSpinF']
    #this part is used to handle the under/overflow of the Spin (so in the real world application the update at the end would happen to the Spin itself)
    if (last_endSpinF == 0 and endSpinF == 0) or endSpinF < last_endSpinF:
      endFrame = endFrame-1
    else:
      endFrame = endFrame+1

    window['endFrame'].update(endFrame)

window.close()

Screenshot, Sketch, or Drawing

Start by running the supplied minimal example with Python 3.9.4, PySimpleGUI 4.40.0, and the tkinter port, then trace how Spin handles enable_events while its button is held. Done means repeated up/down value changes produce corresponding events before the click is released, while the existing example continues to work.
