How would I accomplish the following HTML5 canvas stroke using Python? Would I use Tkinter? Qt? WxWidgets? Some other library?
<!DOCTYPE html>
<html>
<body>
<canvas id="myCanvas" width="300" height="150" style="border:1px solid #d3d3d3;">
</canvas>
<script>
var c = document.getElementById("myCanvas");
var ctx = c.getContext("2d");
ctx.beginPath();
ctx.moveTo(20,20);
ctx.lineTo(20,100);
ctx.lineTo(70,100);
ctx.strokeStyle="red";
ctx.stroke();
</script>
</body>
</html>
With tkinter use can use the Canvas widget type. You can't directly change the color of the border; I'm not sure if that's part of the question or not. You can easily draw a colored border, or put it inside a colored frame to give it a border.
To create the line, use the create_line method.
Here's an example:
import Tkinter as tk
class Example(tk.Frame):
def __init__(self, root):
tk.Frame.__init__(self, root)
self.canvas = tk.Canvas(width=300, height=150,borderwidth=1)
self.canvas.pack(side="top", fill="both", expand=True)
points = (20,20,20,100,70,100)
self.canvas.create_line(points, fill="red")
if __name__ == "__main__":
root = tk.Tk()
Example(root).pack(fill="both", expand=True)
root.mainloop()
