how i can get cursor coordinate and using mouse position in other panel in wxpython

I am trying to put a cursor and rectangle patch that can moved and that can display the coordinates or rather pixel of an image select and display on another panel Paneltwo in the textctrl each time I move the mouse ( automatically rectangel) the pixels of each point are displayed on the other panel

the first problem that the rectangle can't moved with mouse ! the second that what i need to do is when the rectangle moved with mouse i can visualize the pixel or position of mouse ( rectangle) in panel two textctrl ! how can I do that ?

that part of code :

 import wx
from numpy import arange, sin, pi,cos
import numpy as np
from matplotlib.backends.backend_wxagg import FigureCanvasWxAgg as FigureCanvas
from matplotlib.widgets import RectangleSelector
from matplotlib.figure import Figure

        wx.Panel.__init__(self, parent,name="Main", size = (600,400))

class Panel(wx.Panel):

        panel = wx.Panel(self)
        self.panel_two = PanelTwo(parent=self)

        canvas_sizer = wx.BoxSizer(wx.HORIZONTAL)
        canvas_sizer.Add(self.canvas_panel,1,wx.EXPAND)
        canvas_sizer.Add(self.panel_two,1,wx.EXPAND)
        sizer = wx.BoxSizer(wx.VERTICAL)
        sizer.Add(panel)
        sizer.Add(canvas_sizer)
        self.SetSizerAndFit(sizer)
        self.Show()

class CanvasPanel(wx.Panel):
    """ Panel du graphique matplotlib """
    def __init__(self, parent , size=(200,250)):
        super().__init__(parent)
        self.figure = Figure(figsize =(4,3))
        self.canvas = FigureCanvas(self, -1, self.figure)
        self.axes = self.figure.add_subplot(111)
        self.Size = self.canvas.Size
        self.parent = parent
        t = arange(0.5, 3.0, 0.01)
        s = cos(2 * pi * t)
        self.axes.plot(t, s)



     #can'tmove rectangel with mouse    
    def on_press(self,event):
        xpress, ypress = event.xdata, event.ydata
        w = rect.get_width()
        h = rect.get_height()
        rect.set_xy((xpress-w/2, ypress-h/2))

        ax.lines = []   
        ax.axvline(xpress, c='b')
        ax.axhline(ypress, c='b')

        self.fig.canvas.draw()


        self.fig = plt.figure

        self.axes = plt.subplot(111)
        self.axes.imshow(t,s)

        self.fig.canvas.mpl_connect('button_press_event',on_press)


        self.rect = patches.Rectangle((x,y),0.01,0.01,linewidth=1,edgecolor='g',facecolor='none')

        self.axes.add_patch(rect)

        self.plt.show()

class PanelTwo(wx.Panel): #here when i need to visualize pixel and coordinator cursor
    def __init__(self,parent):
        wx.Panel.__init__(self,parent,size=(200,250))

        self.text_ctrl = wx.TextCtrl(self, -1, "", style=wx.TE_MULTILINE|wx.BORDER_SUNKEN|wx.TE_READONLY|
                                wx.TE_RICH2, size=(200,170), pos = (40,20))

        lbl = wx.StaticText(self,label="Coordinato cursor & Pixel " , pos=(40,0))

app = wx.App()
frame = MainFrame(None).Show()
app.MainLoop()

THANK YOU

Solution

Try this and see if it moves you in the right direction.
Note: I have no idea how you are going to retrieve the pixel position from that plot.
Perhaps someone else, who actually knows what they are doing with matplotlib, because I certainly don't, can help with that.
