windows · 画布与绘制后端

tkdeft 的"窗口/画布"层：把矢量图变成 Tkinter 控件。

本子包提供三个零件：

============================ ================================================ :class:~tkdeft.windows.canvas.DCanvas 可以画矢量图的 tkinter.Canvas :class:~tkdeft.windows.draw.DDraw 绘制后端基类（矢量 → 图片） :class:~tkdeft.windows.draw.DSvgDraw svgwrite + tksvg / Wand 后端 :class:~tkdeft.windows.drawwidget.DDrawWidget 带 hover/按压/焦点状态的控件骨架 ============================ ================================================

快速上手

::

import tkinter
from tkdeft.windows.canvas import DCanvas

root = tkinter.Tk()
canvas = DCanvas(root, width=200, height=100)
canvas.pack()

# 一行画一个圆角矩形：栅格引擎走位图快速路径，否则自动回退 SVG
canvas.draw_roundrect(0, 0, 120, 32, 6, fill="#ffffff", outline="#000000")
root.mainloop()
