Grouping Widgets on different panel to respond to parent.GetGrandParent().FindWindowByName

Thanks to Zetcode for the great tutorials on wxpthon, There is something that
captured my attention on the zetcode toturial on the lession of ListControl,
while giving a demo he showed a code that i didn't understand quite well
which is "parent.GetGrandParent().FindWindowByName", which behaved much fine
when a ListControl is clicked items corresponding to the clicked actions are
displayed on the right ListControl. Here are my question?

Suppose i have a group of widgets like wx.TextCtrl, wx.StaticText,
wx.Button, and much much more!!!, is there a way i can make them such that
they can be called by "parent.GetGrandParent().FindWindowByName"? and be
displayed on the other panel.

If it is not possible please reffer me to any other way which can accomplish
this, style used by zetcode to change item on different panel by
"parent.GetGrandParent().FindWindowByName"

Please try to see this Picture of My Application and you will now what i
mean, If you want the source code i will upload them for you, just 3 files.

I think you end up linking things too much together.

You might want to consider "pubsub" which is distributed with wxPython.

Exactly. You need a publisher, an object that has two methods:
def publish(signal, *args) # used by the model
def subscribe(signal, handler) # used mostly in the initialization of the controller

wx.lib.pubsub (I’m not sure if this is the module) is an acepptable solution but it has problems with pyInstaller.

I think what you want to understand is how to communicate information from one panel to another, yes?

The simplest way is to name your objects like self.textCtrl, self.staticText, etc. Now they are all available in the frame’s namespace. So, for example (here “self” refers to the frame):

#Panels on left and right
self.left_panel = wx.Panel(parent=self)
self.right_panel = wx.Panel(parent=self)

#Text controls on left and right
self.textCtrl_left= wx.TextCtrl(parent=self.left_panel)
self.textCtrl_right= wx.TextCtrl(parent=self.right_panel)

#A button on rhe right
self.button_right = wx.Button(parent=self.right_panel,label=‘Press me’)

#Now bind that button
self.button_right.Bind(wx.EVT_BUTTON, self.OnButtonRight)

#In the event handler, you can pass things easily from right to left:

def OnButtonRight(self,event):

#get the text from the text control on the right...
value_of_right_textCtrl = self.textCtrl_right.GetValue()

#...and display it on the left:
self.textCtrl_left.SetValue(value_of_right_textCtrl)

There are other ways to pass information around, such as pubsub, as was mentioned. But this is simple and gets you started.

What problems with pyInstaller?

I package it with py2exe and while there were problems they have been resolved in the latest version.
