如何更改 Tkinter 按钮颜色
Tkinter Button 控件具有属性 bg 和 fg 来设置背景和前景色。我们可以在初始化 Button 对象时为 bg 和 fg 分配颜色，并使用 configure 方法更改 Tkinter Button 的颜色或为 bg 和 fg 键分配新值。
设置 Tkinter Button 颜色
import tkinter as tk
class Test():
def __init__(self):
self.root = tk.Tk()
self.root.geometry("250x100")
self.buttonA = tk.Button(self.root,
text = "Color",
bg = "blue",
fg = "red")
self.buttonB = tk.Button(self.root,
text="Click to change color",
bg = "gray",
fg = "purple")
self.buttonA.pack(side=tk.LEFT)
self.buttonB.pack(side=tk.RIGHT)
self.root.mainloop()
app=Test()
你也可以将 bg 替换为 background，将 fg 替换为 foreground 来设置 Tkinter Button 背景和前景色。
import tkinter as tk
class Test():
def __init__(self):
self.root = tk.Tk()
self.root.geometry("250x100")
self.buttonA = tk.Button(self.root,
text = "Color",
background = "blue",
foreground = "red")
self.buttonB = tk.Button(self.root,
text="Click to change color",
background = "gray",
foreground = "purple")
self.buttonA.pack(side=tk.LEFT)
self.buttonB.pack(side=tk.RIGHT)
self.root.mainloop()
app=Test()
用 configure 方法改变 Tkinter Button 颜色
创建 Tkinter Button 控件之后，我们可以使用 configure 方法更改其颜色。
import tkinter as tk
class Test():
def __init__(self):
self.root = tk.Tk()
self.root.geometry("250x100")
self.buttonA = tk.Button(self.root,
text = "Color",
bg = "blue",
fg = "red")
self.buttonB = tk.Button(self.root,
text="Click to change color",
command=self.changeColor)
self.buttonA.pack(side=tk.LEFT)
self.buttonB.pack(side=tk.RIGHT)
self.root.mainloop()
def changeColor(self):
self.buttonA.configure(bg="yellow")
app=Test()
self.buttonA.configure(bg="yellow")
它将背景 bg 配置为黄色。
使用 bg /fg 属性更改 Tkinter Button 颜色
bg 和 fg 是 Tkinter Button 控件对象字典的键值，因此，我们可以通过为这些键指定新的值来更改 Tkinter Button 的颜色。
import tkinter as tk
class Test():
def __init__(self):
self.root = tk.Tk()
self.root.geometry("250x100")
self.buttonA = tk.Button(self.root,
text = "Color",
bg = "blue",
fg = "red")
self.buttonB = tk.Button(self.root,
text="Click to change color",
command=self.changeColor)
self.buttonA.pack(side=tk.LEFT)
self.buttonB.pack(side=tk.RIGHT)
self.root.mainloop()
def changeColor(self):
self.buttonA["bg"]="gray"
self.buttonA["fg"]="cyan"
app=Test()
