问题描述
限时送ChatGPT账号..我正在尝试使用 tkinter 为我的脚本获取圆形按钮.
I am trying to get rounded buttons for my script using tkinter.
我发现以下代码:
from tkinter import *
import tkinter as tk
class CustomButton(tk.Canvas):
def __init__(self, parent, width, height, color, command=None):
tk.Canvas.__init__(self, parent, borderwidth=1,
relief="raised", highlightthickness=0)
selfmand = command
padding = 4
id = self.create_oval((padding,padding,
width+padding, height+padding), outline=color, fill=color)
(x0,y0,x1,y1) = self.bbox("all")
width = (x1-x0) + padding
height = (y1-y0) + padding
self.configure(width=width, height=height)
self.bind("<ButtonPress-1>", self._on_press)
self.bind("<ButtonRelease-1>", self._on_release)
def _on_press(self, event):
self.configure(relief="sunken")
def _on_release(self, event):
self.configure(relief="raised")
if selfmand is not None:
selfmand()
app = CustomButton()
app.mainloop()
但我收到以下错误:
TypeError: __init__() missing 4 required positional arguments: 'parent', 'width', 'height', and 'color'
推荐答案
在 tkinter 中制作圆形按钮的一个非常简单的方法是使用图像.
A very easy way to make a rounded button in tkinter is to use an image.
首先创建您希望按钮看起来像的图像,将其另存为 .png 并删除外部背景,使其四舍五入,如下所示:
First create an image of what you want you button to look like save it as a .png and remove the outside background so it is rounded like the one below:
接下来将图像插入一个带有 PhotoImage
的按钮,如下所示:
Next insert the image in a button with PhotoImage
like this:
self.loadimage = tk.PhotoImage(file="rounded_button.png")
self.roundedbutton = tk.Button(self, image=self.loadimage)
self.roundedbutton["bg"] = "white"
self.roundedbutton["border"] = "0"
self.roundedbutton.pack(side="top")
确保使用border="0"
,按钮边框将被移除.
Ensure to use border="0"
and the button border will be removed.
我添加了 self.roundedborder["bg"] = "white"
以便按钮的背景与 Tkinter 窗口的背景相同.
I added the self.roundedborder["bg"] = "white"
so that the the background the background of the button is the same as the Tkinter window.
最重要的是,您可以使用任何您喜欢的形状,而不仅仅是普通的按钮形状.
The great part is that you can use any shape you like not just the normal button shapes.
