tkinter非常慢 - 如何加速或使用不同的库？ [英] tkinter is very slow - how to speed it up or use a different library?

问题描述

我使用tkinter生成2D形态图。我觉得它非常慢。例如，这个脚本在我的8核Xeon上花费了将近10秒钟的时间：

 ＃！/ usr / bin / env python3 
 
进口随机
进口tkinter为tk 
 
 A = 3.419384662527591 
 B = 2.0158889752347022 
 C = 19.479697084985673 
 D = 61.006212908774614 
 F = 1.3449991745874286 
 G = 1.9590223710983992 
 H = 5.129501734860241 
 WIDTH = 800 
 HEIGHT = 600 
 
 
类形态（tk .frame）：
 $ b $ def __init __（self，root）：
 tk.Frame .__ init __（self，root）
 self.canvas = tk.Canvas（width = WIDTH， height = HEIGHT，borderwidth = 1）
 self.canvas.pack（side =top，fill =both，expand = True）
 
 def rand（self）：
 A = 3 + random.random（）* 10 
 B = 1 + random.random（）* 5 
 C = 1 + random.random（）* 20 
 D = 1 + random.random（）* 200 
 F = 1 + random.random（）* 2 
 G = 1 + random.random（）* 20 
 H = 1 + random.random ） * 20 
 
 def draw（self）：
 points = [0] * HEIGHT 
 points_space = [0] * HEIGHT 
 points_energy = [0] * HEIGHT 
w = WIDTH 
h = HEIGHT 
 min_x = 0 
 
 last_x = 0 
 last_y = 0 
 
，而min_x< w：
 min_x = w 
 lrand = 0 
 
对于范围（1，h）中的y：
 points_space [y] = points_space [y] + \ 
（points_space [y  -  1]  -  points_space [y]）/ F 
 
在范围内（0，h）：
 lrand = lrand +（random.random（ ） -  0.5）/ C 
 new_point = points [y] + points_space [y] + lrand 
 points_space [y] =（new_point  -  points [y]）+ \ 
 points_energy [y ] / G 
 points_space [y] = points_space [y] +（A  -  points_space [y]）/ D 
 points_energy [y] = points_energy [y] / H 
 
如果（points_space [y]  points_energy [y] = points_space [y]  -  B 
 points_space [y] = B 
 
 points [y] = points [y] + points_space [y] 
 
 if（min_x> points [y]）：
 min_x = point s [y] 
 
 self.canvas.create_line（last_x，last_y，points [y]，y）
 last_x = points [y] 
 last_y = y 
 
 
 if __name__ ==__main__：
 root = tk.Tk（）
m =形态（根）
 m.pack（fill =both， expand = True）
 m.rand（）
 m.draw（）
 root.mainloop（）
  

tkinter对于这类工作太弱了吗？我应该在看一个不同的2D库吗？

解决方案

我也使用Tk作为应用程序。

这是一个使用XML文件自动生成GUI的应用程序，而TK太慢了。

我转换到PYside，并对此非常高兴。它不像Tkinter那么容易使用，但它的速度更快，并具有很多可能性

I am generating 2D morphogenic plots using tkinter. I find it incredibly slow. For example, this script takes almost 10 seconds on my 8-core Xeon:

#!/usr/bin/env python3

import random
import tkinter as tk

A = 3.419384662527591
B = 2.0158889752347022
C = 19.479697084985673
D = 61.006212908774614
F = 1.3449991745874286
G = 1.9590223710983992
H = 5.129501734860241
WIDTH = 800
HEIGHT = 600


class Morphogenic(tk.Frame):

    def __init__(self, root):
        tk.Frame.__init__(self, root)
        self.canvas = tk.Canvas(width=WIDTH, height=HEIGHT, borderwidth=1)
        self.canvas.pack(side="top", fill="both", expand=True)

    def rand(self):
        A = 3 + random.random() * 10
        B = 1 + random.random() * 5
        C = 1 + random.random() * 20
        D = 1 + random.random() * 200
        F = 1 + random.random() * 2
        G = 1 + random.random() * 20
        H = 1 + random.random() * 20

    def draw(self):
        points = [0] * HEIGHT
        points_space = [0] * HEIGHT
        points_energy = [0] * HEIGHT
        w = WIDTH
        h = HEIGHT
        min_x = 0

        last_x = 0
        last_y = 0

        while min_x < w:
            min_x = w
            lrand = 0

            for y in range(1, h):
                points_space[y] = points_space[y] + \
                    (points_space[y - 1] - points_space[y]) / F

            for y in range(0, h):
                lrand = lrand + (random.random() - 0.5) / C
                new_point = points[y] + points_space[y] + lrand
                points_space[y] = (new_point - points[y]) + \
                    points_energy[y] / G
                points_space[y] = points_space[y] + (A - points_space[y]) / D
                points_energy[y] = points_energy[y] / H

                if (points_space[y] < B):
                    points_energy[y] = points_space[y] - B
                    points_space[y] = B

                points[y] = points[y] + points_space[y]

                if (min_x > points[y]):
                    min_x = points[y]

                self.canvas.create_line(last_x, last_y, points[y], y)
                last_x = points[y]
                last_y = y


if __name__ == "__main__":
    root = tk.Tk()
    m = Morphogenic(root)
    m.pack(fill="both", expand=True)
    m.rand()
    m.draw()
    root.mainloop()

Is tkinter just too weak for this kind of work? Should I be looking at a different 2D library?

解决方案

I used Tk for an application as well.

It was an application with an auto generated GUI from XML files, and TK was simply too slow.

I Switched to PYside and have been very happy about it. Its not as easy to use as Tkinter, but its much faster and has a lot of posibilities
