如何在 tkinter 中单击时使按钮填充

  • 772

在此处输入图像描述

1 - 按键按钮-1

2 - 未按下键且没有焦点

按下按钮（按钮 1）时，我需要按钮（图片 2），而不是将其浮雕更改为图片 1

来源，下图

from tkinter import*

root = Tk()
root.geometry("200x200")
canvas = Canvas(root, bg="white")
canvas.place(x=-5,y=-5)


ico_disstbl = PhotoImage(file="close_distbl.png")

but = Button(canvas, bg="red", image=ico_disstbl, relief=FLAT, overrelief=GROOVE)
but.place(x=100-18+5, y=100-27+5, width=27, height=18)

root.mainloop()

照片：在此处输入图像描述下载和名称close_distbl.png

    使用参数activebackground来处理按钮被点击时的背景颜色

    from tkinter import*

root = Tk()
root.geometry("200x200")
canvas = Canvas(root, bg="white")
canvas.place(x=-5, y=-5)


ico_disstbl = PhotoImage(file="close_distbl.png")

but = Button(canvas, bg="red", image=ico_disstbl, activebackground="red", relief=SUNKEN)
but.place(x=87, y=78, width=27, height=18)

root.mainloop()

  2. 如果您希望在单击时不改变浮雕，您可以简单地Button使用Label. 为方便起见，您可以继承Label并让新类伪装成一个按钮。

    import tkinter as tk


class FlatButton(tk.Label):
    def __init__(self, *args, overrelief=tk.FLAT, command=None, **kwargs):
        super().__init__(*args, **kwargs)

        self.relief = kwargs.get('relief', tk.FLAT)
        self.overrelief = overrelief

        if command:
            self.bind('<1>', command)

        self.bind('<Enter>', self.mouse_in)
        self.bind('<Leave>', self.mouse_out)

    def mouse_in(self, event):
        self.config(relief=self.overrelief)

    def mouse_out(self, event):
        self.config(relief=self.relief)


root = tk.Tk()
root.geometry("200x200")
canvas = tk.Canvas(root, bg="white")
canvas.place(x=-5, y=-5)

ico_disstbl = tk.PhotoImage(file="close_distbl.png")

but = FlatButton(canvas, bg="red", image=ico_disstbl, relief=tk.FLAT, overrelief=tk.GROOVE,
                 command=lambda event: print('Hello!'))

but.place(x=87, y=78, width=27, height=18)

root.mainloop()
