如何控制tkinter应用程序的亮度

Question

我只是想知道是否有一种方法可以在不影响桌面亮度的情况下更改tkinter应用程序的亮度。

Answer 1

以下是tkinter中亮度颜色的演示。

tk_set_Palette将影响大多数tkinter小部件。哎呀，在我的代码中发现了一个错误，所以我已经清理了

def find( obj ):
'''return string of keys & values for any tkinter widget that has keys attribute'''
name = f"{type(obj).__name__}:n    "
try:
return name + "n    ".join( [ f"{x} = '{obj.cget(x)}'" for x in obj.keys() ] )
except:
return f"'{obj}' has no keys attribute"

if __name__ == '__main__':
bright = brightness( )
tkinter.mainloop()
