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

Start at the sg.Slider entry point and reproduce the reported layout with the four slider sizes in the issue body on the tkinter port. Confirm that the size height is interpreted in rows, including size=(30,1), and use the demonstrated behavior as the completion check.
