我需要一些方法来在 PySimpleGUI 中的滑块上方显示一个十进制值。

我已经尝试过输入十进制值,但是当我这样做时会引发错误。

import PySimpleGUI as sg

layout = [sg.Slider(range=(850,999), default_value=997, size=(40,15), orientation='horizontal')]

我希望它在滑动范围时显示十进制值,但现在它所做的只是将其设置为 850 或 999,而不是 85.0 和 99.9。

当然,您只需将范围定义为 85 到 99 并将分辨率设置为 0.1

layout = [[sg.Slider(range=(85.0,99.9), default_value=99.7, resolution=.1, size=(40,15), orientation='horizontal')]]

此处的文档中对此进行了讨论: https ://pysimplegui.readthedocs.io/en/latest/#slider-element

IDE 中显示的文档字符串还显示范围可以是浮点数,并将其他值也列为可能是浮点数。如果它们没有出现在您的 IDE 中,请使用 Python 的帮助系统
