add button hide in canvas wxpython4

Maj1 · May 24, 2019, 7:57am

hi ,

i need to add hide button in canvas i the same panel how can i do that how i can have space to add the button ?

i have no idea if is possible to add button in two canvas button ’ plot" like the picture :

that is my code with 2 panels and 2 canvas

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

class MainFrame(wx.Frame):
def init(self, parent ):
wx.Panel.init(self, parent,name=“Main”, size = (600,800))
Top = PanelTop(self)
Bottom = PanelBottom(self)
sizer = wx.BoxSizer(wx.VERTICAL)
sizer.Add(Top, 1, wx.EXPAND)
sizer.Add(Bottom, 1, wx.EXPAND)
self.SetSizer(sizer)

class PanelTop(wx.Panel):
def init(self,parent):
wx.Panel.init(self,parent,size = (300,300))
self.SetBackgroundColour(‘white’)
self.figure = Figure(figsize = (4,5))
self.axes = self.figure.add_subplot(111)
self.canvas = FigureCanvas(self,-1,self.figure)
self.sizer = wx.BoxSizer(wx.VERTICAL)
self.sizer.Add(self.canvas, 1, wx.LEFT | wx.TOP | wx.GROW)
self.SetSizer(self.sizer)
    t = arange(0.5, 3.0, 0.01)
    s = cos(2 * pi * t)
    self.axes.plot(t, s)
class PanelBottom(wx.Panel):
def init(self,parent):
wx.Panel.init(self, parent, size = (300,300))
self.SetBackgroundColour(‘grey77’)
self.figure = Figure(figsize = (4,5))
self.axes = self.figure.add_subplot(111)
self.canvas = FigureCanvas(self,-1,self.figure)
self.sizer = wx.BoxSizer(wx.VERTICAL)
self.sizer.Add(self.canvas, 1, wx.LEFT | wx.TOP | wx.GROW)
self.SetSizer(self.sizer)
    t = arange(0.0, 3.0, 0.01)
    s = sin(2 * pi * t)
    self.axes.plot(t, s)
app = wx.App()
frame = MainFrame(None).Show()
app.MainLoop()

thank you

Of course it is. You just need to decide where they should go. Here's a version of your code with the buttons in between the two panels.

One little comment -- you had this in your code:

 class MainFrame\(wx\.Frame\):
     def \_\_init\_\_\(\*self, parent\):
         wx\.Panel\.\_\_inot\_\_\(self, parent, name=&quot;Main, size=\(600,800\)\)

Note that you derived from wx.Frame, but you called the wx.Panel constructor. That's not proper. It IS somewhat common you create a frame and have it contain a panel which then holds all the other objects, but the panel has to be created separately.

import wx
import numpy as np
from matplotlib.backends.backend_wxagg import FigureCanvasWxAgg as FigureCanvas

class MainFrame(wx.Frame):

sizer = wx.BoxSizer(wx.VERTICAL)
sizer.Add(Top, 1, wx.EXPAND)

     buttonsizer = wx\.BoxSizer\(wx\.HORIZONTAL\)
     btn1 = wx\.Button\(self, \-1, &quot;Hide top&quot; \)
     btn2 = wx\.Button\(self, \-1, &quot;Hide bottom&quot; \)

     t = np\.arange\(0\.5, 3\.0, 0\.01\)

Why would you do that? When you hide PanelTop, the buttons will go way as well. If you need to hide the panels, then I don't think you want the buttons to be part of a panel.

Still, I would hope it is obvious how to make that change.
