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

When passing the size=() parameter to sg.Slider. the height is supposed to be specified in rows. However, it appears to be in pixels.

Code To Duplicate

A short program that isolates and demonstrates the problem (Do not paste your massive program, but instead 10-20 lines that clearly show the problem)

This pre-formatted code block is all set for you to paste in your bit of code:

import PySimpleGUI as sg

layout=[
    [sg.Slider(key='slider1', orientation='h')], # default works fine
    [sg.Slider(key='slider2', orientation='h', size=(30,1))], # height should be 1 row, but sizes in pixels
    [sg.Slider(key='slider3', orientation='h', size=(30,5))], # height should be 5 row, but sizes in pixels
    [sg.Slider(key='slider4', orientation='h', size=(30,18))] # 18 pixels looks more normal
]

win=sg.Window('Slider bug demo', layout, finalize=True)

while True:
    event, values = win.read()
    if event == sg.WIN_CLOSED or event == 'Exit':
        break

Screenshot, Sketch, or Drawing

Parti dal punto di ingresso sg.Slider e riproduci nel port tkinter il layout segnalato con le quattro dimensioni dello slider indicate nel corpo dell’issue. Conferma che l’altezza della dimensione viene interpretata in righe, incluso size=(30,1), e usa il comportamento dimostrato come verifica del completamento.
