Question

我有两个GUI，我希望这些GUI能够一起通信。我过去使用过Matlab，在Matlab中，我使用过addlistener，基本上可以在多个GUI之间进行通信。我是python的新手，我想在第二个gui上单击显示按钮时更新第一个gui上的轴。基本上，根据我在另一个GUI上选择的路径在另一个gui上绘制图像。

Here is the image for better understanding

代码如下：

from tkinter import *
from PIL import Image, ImageTk
from matplotlib.figure import Figure
from matplotlib.backends.backend_tkagg import 
FigureCanvasTkAgg
import PySimpleGUI as sg
import tkinter.filedialog as fdialog
from natsort import natsorted
import os
import cv2


class MyCanvas(Canvas):


def __init__(self, parent=None, img=None, *parms, **kparms):
    Canvas.__init__(self, parent, *parms, **kparms)

    self._width = 20;
    self._height = 10;
    self._starting_drag_position = ()
    self.config(width=self._width, height=self._height, bg='white')
    self._draw_some_example_objects()

    self.pack(fill=BOTH, expand=YES)

def _draw_some_example_objects(self):
    self.fig = Figure()
    gs = self.fig.add_gridspec(5, 2)
    self.axis= self.fig.add_subplot(gs[0:4, 0])
    self.canvas = FigureCanvasTkAgg(self.fig, master=self)
    self.canvas.get_tk_widget().pack(side="top", fill='both', expand=True)
    colors = dict(outline="black")

class MyGUI(Tk):

def __init__(self, *args, **kwargs):
    Tk.__init__(self, *args, **kwargs)
    self.title("Drag canvas with mouse")
    self.geometry("700x700")
    """For some reason menu should be added here"""
    self.menuBar = Menu(master=self)
    self.filemenu = Menu(self.menuBar, tearoff=0)
    self.filemenu.add_command(label="listview!", command=self.list)
    self.menuBar.add_cascade(label="File", menu=self.filemenu)
    self.config(menu=self.menuBar)

    self._addWidgets()

def _addWidgets(self):
    my_canvas = MyCanvas(self)

def list(self):
    listView(self)


def listView(self):
sg.ChangeLookAndFeel('GreenTan')

dir = fdialog.askdirectory()
filesList = os.listdir(dir)
filesList = natsorted(filesList)
layout = [
       [sg.Listbox(values=(filesList), size=(60, 30), key='_IN_')],
       [sg.Button('Show')]
]

window = sg.Window('Everything bagel', default_element_size=(40, 1), grab_anywhere=False).Layout(layout)

while True:
  event, values = window.Read()
  if event is None or event == 'Exit':
      break
  print(dir + values.get('_IN_')[0])


if __name__ == '__main__':
    MyGUI().mainloop()`

看看这个demo program。

将您的代码放到显示以下内容的部分：

#------------------------ PASTE YOUR MATPLOTLIB CODE HERE ----------------------

确保图形位于变量“ fig”中。它将创建一个带有GUI选项的窗口，并将您的Matplotlib图嵌入其中。
