使用 Tkinter 进行多线程 Python

我用这些函数在画布上画小圆圈：

这是绘制圆圈的函数：

class Fourmis:

def __init__(self, can, posx, posy, name, radius):
    self.can = can

    self.largeur_can = int(self.can.cget("width"))
    self.hauteur_can = int(self.can.cget("height"))

    self.posx = posx
    self.posy = posy
    self.name = name 
    self.radius = radius

    self.ball1 = self.can.create_oval(self.posy, self.posx, self.posy+radius, self.posx+radius, outline=self.name, fill=self.name, width=2)

    self.nx = randrange(-10,10,1)
    self.nx /= 2.0
    self.ny = randrange(-10,10,1)
    self.ny /= 2.0

    #self.can.bind("<Motion>", self.destruction, add="+") 
    self.statut = True

    self.move()

def move(self):
    if self.statut == True :
        self.pos_ball = self.can.coords(self.ball1)
        self.posx_ball = self.pos_ball[0]
        self.posy_ball = self.pos_ball[1]

        if self.posx_ball < 0 or (self.posx_ball + self.radius) > self.largeur_can:
            self.nx = -self.nx         
        if self.posy_ball < 0 or (self.posy_ball + self.radius) > self.hauteur_can:
            self.ny = -self.ny

        self.can.move(self.ball1, self.nx, self.ny)

        self.can.after(10, self.move)

这个创建了画布和圆圈：

class App(Frame):

def __init__(self):
    self.root=Tk()
    self.can=Canvas(self.root,width=800,height=600,bg="black")
    self.can.pack()

    self.create(50, "green")
    self.create(50, "purple")



def mainloop(self):
    self.root.mainloop()


def create(self, i, name):
    for x in range(i):
        self.x=Fourmis(self.can,100,400, name,0)

我调用这些行来运行该项目：

jeu = App()
jeu.mainloop()

正确的执行方式是什么self.create(50, "green") and self.create(50, "purple")在不同的线程中？

我已尝试以下操作，但无法使其工作：

class FuncThread(threading.Thread):
def __init__(self, i, name):
    self.i = i
    self.name = name
    threading.Thread.__init__(self)

def run(self):
    App.create(self, self.i, self.name)

有人能告诉我如何运行这些线程吗？

当需要此功能时，您要做的就是通过将您希望执行的事件放入线程共享的队列中来安排它们。这样，在给定线程中，您可以指定要通过排队来运行“create(50, ...)”，并且主线程使事件出队并执行它。

这是在第二个线程中创建移动球的基本示例：

import threading
import Queue
import random
import math
import time
import Tkinter

random.seed(0)

class App:
    def __init__(self, queue, width=400, height=300):
        self.width, self.height = width, height
        self.canvas = Tkinter.Canvas(width=width, height=height, bg='black')
        self.canvas.pack(fill='none', expand=False)
        self._oid = []
        self.canvas.after(10, self.move)

        self.queue = queue
        self.canvas.after(50, self.check_queue)

    def check_queue(self):
        try:
            x, y, rad, outline = self.queue.get(block=False)
        except Queue.Empty:
            pass
        else:
            self.create_moving_ball(x, y, rad, outline)
        self.canvas.after(50, self.check_queue)

    def move(self):
        width, height = self.width, self.height
        for i, (oid, r, angle, speed, (x, y)) in enumerate(self._oid):
            sx, sy = speed
            dx = sx * math.cos(angle)
            dy = sy * math.sin(angle)
            if y + dy + r> height or y + dy - r < 0:
                sy = -sy
                self._oid[i][3] = (sx, sy)
            if x + dx + r > width or x + dx - r < 0:
                sx = -sx
                self._oid[i][3] = (sx, sy)
            nx, ny = x + dx, y + dy
            self._oid[i][-1] = (nx, ny)
            self.canvas.move(oid, dx, dy)
        self.canvas.update_idletasks()
        self.canvas.after(10, self.move)

    def create_moving_ball(self, x=100, y=100, rad=20, outline='white'):
        oid = self.canvas.create_oval(x - rad, y - rad, x + rad, y + rad,
                outline=outline)
        oid_angle = math.radians(random.randint(1, 360))
        oid_speed = random.randint(2, 5)
        self._oid.append([oid, rad, oid_angle, (oid_speed, oid_speed), (x, y)])

def queue_create(queue, running):
    while running:
        if random.random() < 1e-6:
            print "Create a new moving ball please"
            x, y = random.randint(100, 150), random.randint(100, 150)
            color = random.choice(['green', 'white', 'yellow', 'blue'])
            queue.put((x, y, random.randint(10, 30), color))
        time.sleep(0) # Effectively yield this thread.

root = Tkinter.Tk()
running = [True]

queue = Queue.Queue()

app = App(queue)
app.create_moving_ball()
app.canvas.bind('<Destroy>', lambda x: (running.pop(), x.widget.destroy()))

thread = threading.Thread(target=queue_create, args=(queue, running))
thread.start()

root.mainloop()
