• 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

Detailed Description

Just a Question:
Is it possible to change the colors of scrollbar in combo to look like listbox?
scrollbar and sbar_through, sbar_tips of Combobox and Menubutton don't look like those of other scrollbars and keep their colors no matter which theme is selected.

Code To Duplicate

import sys
import PySimpleGUI as sg
from random import choice as rc

def main(theme):
    sg.theme(theme) 
    win_layout = [
        [sg.Listbox(values = sg.theme_list(),
            size =(20, 12), 
            key ='-THEME LISTBOX-',
            enable_events = True),
         sg.vtop(   
         sg.Combo(values= sg.theme_list(),  
            default_value=theme,
            size=(20, 11), 
            key='-THEME COMBO-',
            enable_events=True, pad=(25,0))),
        ],
    ]
    window = sg.Window('Color Test', win_layout, resizable=True, 
            margins=(0,0), use_custom_titlebar=True, 
            finalize=True, keep_on_top=True)

    while True:
        e, v = window.read(timeout=200)
        if e in (None, 'Exit'):
            break
    window.Close()


if __name__ == '__main__':
    themes = sg.theme_list()
    theme  = rc(themes) if len(sys.argv) < 2  else sys.argv[1]
    main(theme)

Workaround here

import PySimpleGUI as sg

def new_window(theme):
    sg.theme(theme)
    layout = [
        [
            sg.Listbox(values=themes, default_values=[themes[0]], size=(width, 12), key='-LISTBOX-'),
            sg.vtop(sg.Combo(values=themes, size=(width, 11), key='-COMBO-')),
        ],
    ]
    window = sg.Window('Color Test', layout, finalize=True)
    root = window.TKroot
    combo = window['-COMBO-']
    window.force_focus()
    combo.set_focus()
    window.refresh()
    combo.widget.event_generate('<Down>')

    # Workaround after window finalized

    fg, bg = sg.theme_button_color()
    style_name = combo.ttk_style_name + ".Vertical.TScrollbar"
    style = combo.ttk_style
    style.configure(style_name, arrowcolor=fg, background=bg, troughcolor=sg.theme_slider_color())
    root.tk.eval(f'set popdown [ttk::combobox::PopdownWindow {combo.widget}]')
    root.tk.eval(f'$popdown.f.sb configure -style "{style_name}"')

    window.read(timeout=1000, close=True)

themes = sg.theme_list()
width = max(map(len, themes))
for theme in themes[::10]:
    new_window(theme)

[arminposchmann]

That works, just a comment:
to have the same look with all themes it should be
style.configure(style_name, arrowcolor=newbfg, background=newbbg, troughcolor=newslc = sg.theme_slider_color())
where :
newbbg = sg.LOOK_AND_FEEL_TABLE[theme]['BUTTON'][1]
newbfg = sg.LOOK_AND_FEEL_TABLE[theme]['BUTTON'][0]

Is there a way to set this new ttk style for all combos at once, or must each combo configured this way?

[Jason Yang]

I didn't find any way to configure same style at once for all Combo elements at once.
