Question

嗨，我是一名学生，我是第一次与ktinker合作。我目前正在尝试创建一个遵循此顺序的程序：

在matplotlib中打开地图
调用弹出窗口供用户输入信息
当用户点击地图网格时的坐标和用户信息存储在字典中
matplotlib在位置上生成绘图点

麻烦的是，当我调用我在tkinter中编写的弹出窗口时，调用mainloop（）函数会破坏matplotlib窗口，并且在地图窗口关闭之前它不会生成绘图点。

摆脱mainloop修复它但后来意味着我无法从弹出窗口中获取数据。任何人都知道如何阻止一个人干扰另一个人？我必须将它们保存在单独的类中，因为我的意思是在我的代码中演示模块化。这是主要代码

    import matplotlib.pyplot as plt
import matplotlib.image as mpimg
import numpy as np
import popup1 as ap

__author__ = "k1221169"
__date__ = "$15-Nov-2015 11:29:21$"


markerList = []
xplots = []
yplots = []
desc = ''
title = ''
fig = plt.figure()
ax = fig.add_subplot(111)
ax.plot(np.random.rand(10))
img = mpimg.imread('overland map 1.png')
imgplot = plt.imshow(img)
plt.ylim(ymax=1)
plt.xlim(xmin=1)


def mrkApnd(a,b):
    a.update(b)
    print a
    markerList.append(a)

def onclick(event):

    if spacecheck(event.xdata, event.ydata):
        #print markerList[0]['x']
        idx = np.abs(xplots - event.xdata).argmin()
        print xplots[idx]

        for i in markerList:
            if xplots[idx] == i['x'] :
                print i
                #c = i
                ap.useroutput(i)
    else:
        input1 = ap.userinput()
        input2 = {'x':event.xdata, 'y':event.ydata}
        input1['title'] = title
        input1['desc'] = desc
        mrkApnd(input1,input2)

        drawMarks()
        print input1

    return markerList
cid = fig.canvas.mpl_connect('button_press_event', onclick)

def drawMarks():
    plt.ion()
    for i in markerList:
        xplots.append(i['x'])
        yplots.append(i['y'])
        plt.plot(i['x'], i['y'], i['type'])





def spacecheck(x,y):
    a = bool
    if np.isclose(xplots, x, atol=50.0).any() and np.isclose(yplots, y, atol=50.00).any():
        a=True
        print 'yes'
        return a
plt.draw()
plt.show()

这是从另一个文件调用的弹出代码

from Tkinter import *

class popup1():
    def __init__(self):

        pass

def userinput():


    pop = Toplevel()


    pop.title("marker")
    pop.geometry("300x500+200+200")

    #string for title

    frame = Frame(pop)
    entry = Entry(frame)
    entry.pack(side = TOP)
    frame.pack( padx =20, pady =20)



    #radius button for visibility
    frame2 = Frame(pop)
    selection = StringVar()
    radio_1 = Radiobutton(frame2, text = 'Character', variable = selection, value = 'ob')
    radio_2 = Radiobutton(frame2, text = 'Item', variable = selection, value = 'or')
    radio_3 = Radiobutton(frame2, text='Event',  variable = selection, value = 'oy')

    radio_1.select()
    radio_1.pack(side = LEFT)
    radio_2.pack(side = LEFT)
    radio_3.pack(side = LEFT)
    frame2.pack(padx =30, pady =30)
    #radius button for marker type
    frame3 = Frame(pop)
    visible = bool
    check_1 = Checkbutton(frame3, text = 'GM Only', variable = visible, onvalue= True, offvalue= False)

    check_1.pack(side = LEFT)
    frame3.pack(padx =30, pady =30)
    #string for user input
    frame4 = Frame(pop)
    entry4 = Entry(frame4)
    entry4.pack(side = LEFT)
    frame4.pack( padx =20, pady =20)



    def infoPass():
        #info1 = {'title': entry.get(), 'type': selection.get(), 'vis': visible, 'Desc': entry4.get()}
        #info.update(info1)
        #print info

        pop.destroy()

    #buttons
    label = Label(pop, text="", height=0, width=100)
    label.pack()
    b = Button(pop, text="Cancel", width=20, command= pop.destroy )
    b.pack(side='bottom',padx=5,pady=5)
    b2 = Button(pop, text="Save", width=20, command= infoPass  )
    b2.pack(side='bottom',padx=5,pady=5)
    info = {'title': entry.get(), 'type': selection.get(), 'vis': visible, 'desc': entry4.get()}
    pop.mainloop()
    return info

如果我正确地解答了你的问题，那就试着添加你自己的循环。

删除pop.mainloop（）
使代码成为更清洁代码的类


    class userinput:
        def __init__(self):
            #open your window here and style it etc. and:
            self.data_sent = False
        def infopass(self):
            self.data_sent = True
            #your infopass code here and

在 init ：


        def __init__(self):
            #...
            while self.data_sent == False:
                root.update()

    while data_sent == False:
        pop.update()

通过
调用您的弹出窗口
mypopup = userinput（）

停止tkinter mainloop扰乱matplotlib
