我设法找到了一个在 tkinter 中制作圆形按钮类的人，该类效果很好。然而我遇到的问题是总是有一个白色边框。 我尝试阅读所有代码并更改所有颜色值，但无济于事。
这是工作代码的摘录，我已尽力对其进行格式化:
from tkinter import Tk, Canvas
class RoundedButton(Canvas):
def __init__(self, master=None, text: str = "", radius=25, btnforeground="#007CEE", btnbackground="#ffffff",
clicked=None, font=("Righteous", 25), *args, **kwargs):
super(RoundedButton, self).__init__(master, *args, **kwargs)
self.config(bg=self.master["bg"])
self.btnbackground = btnbackground
self.btnforeground = btnforeground
self.clicked = clicked
self.radius = radius
self.rect = self.round_rectangle(0, 0, 0, 0, tags="button", radius=radius, fill=btnbackground)
self.text = self.create_text(0, 0, text=text, tags="button", fill=btnforeground, font=font,
justify="center")
self.tag_bind("button", "<ButtonPress>", self.border)
self.tag_bind("button", "<ButtonRelease>", self.border)
self.bind("<Configure>", self.resize)
text_rect = self.bbox(self.text)
if int(self["width"]) < text_rect[2] - text_rect[0]:
self["width"] = (text_rect[2] - text_rect[0]) + 10
if int(self["height"]) < text_rect[3] - text_rect[1]:
self["height"] = (text_rect[3] - text_rect[1]) + 10
def round_rectangle(self, x1, y1, x2, y2, radius=25, update=False,
**kwargs): # if update is False a new rounded rectangle's id will be returned else updates existing rounded rect.
# source: https://stackoverflow.com/a/44100075/15993687
points = [x1 + radius, y1,
x1 + radius, y1,
x2 - radius, y1,
x2 - radius, y1,
x2, y1,
x2, y1 + radius,
x2, y1 + radius,
x2, y2 - radius,
x2, y2 - radius,
x2, y2,
x2 - radius, y2,
x2 - radius, y2,
x1 + radius, y2,
x1 + radius, y2,
x1, y2,
x1, y2 - radius,
x1, y2 - radius,
x1, y1 + radius,
x1, y1 + radius,
x1, y1]
if not update:
return self.create_polygon(points, **kwargs, smooth=True)
else:
self.coords(self.rect, points)
def resize(self, event):
text_bbox = self.bbox(self.text)
if self.radius > event.width or self.radius > event.height:
radius = min((event.width, event.height))
else:
radius = self.radius
width, height = event.width, event.height
if event.width < text_bbox[2] - text_bbox[0]:
width = text_bbox[2] - text_bbox[0] + 30
if event.height < text_bbox[3] - text_bbox[1]:
height = text_bbox[3] - text_bbox[1] + 30
self.round_rectangle(5, 5, width - 5, height - 5, radius, update=True)
bbox = self.bbox(self.rect)
x = ((bbox[2] - bbox[0]) / 2) - ((text_bbox[2] - text_bbox[0]) / 2)
y = ((bbox[3] - bbox[1]) / 2) - ((text_bbox[3] - text_bbox[1]) / 2)
self.moveto(self.text, x, y)
def border(self, event):
if event.type == "4":
self.itemconfig(self.rect, fill="#DE8500")
self.itemconfig(self.text, fill='#ffffff')
if self.clicked is not None:
self.clicked()
else:
self.itemconfig(self.rect, fill=self.btnbackground)
self.itemconfig(self.text, fill=self.btnforeground)
window = Tk()
window.geometry("1440x872")
window.configure(bg="#007CEE")
download_button_1 = RoundedButton(
text="Download",
font=("Righteous", 30),
borderwidth=0)
download_button_1.place(
x=409,
y=383,
width=621.0,
height=105.0
)
window.mainloop()
编辑:Furas 的答案非常完美，对于任何有兴趣使用这个圆形按钮类的人，我建议将 splinesteps 更改为 self.create_polygon 的更高值以帮助平滑
return self.create_polygon(points, **kwargs, smooth=True, splinesteps=10000)
最佳答案
在 Linux 上对我有用
highlightthickness=0
或设置背景颜色
highlightbackground="#007CEE"
最终
borderwidth=-1
Canvas 的文档(archive.org 上的 effbot.org 页面)显示所有配置选项。
