How to return selected check boxes using wxPython?

Question

I want to perform following tasks but not getting there:

1] Get checked options under 'OnApply'

2] Once I checked few options then 'Select' or 'UnSelectAll' will only not select/unselect those options which were not selected/selected manually?

Do I need to index all check box options to do above tasks?

Any help to accomplish this would be very appreciative. Please let me know if its not clear.

import wx

class MyCheckBox(wx.Frame):
    def __init__(self, parent, id, title):
        wx.Frame.__init__(self, parent, id, 'Checking Options', size=(470, 400))
        panel = wx.Panel(self, -1)

        self.cb = wx.CheckBox(panel, -1, '', (120, 75))
        self.cb.SetValue(False)
        self.cb = wx.CheckBox(panel, -1, '', (200, 75))
        self.cb.SetValue(False)
        self.cb = wx.CheckBox(panel, -1, '', (278, 75))
        self.cb.SetValue(False)
        self.cb = wx.CheckBox(panel, -1, '', (356, 75))
        self.cb.SetValue(False)

        self.cb = wx.CheckBox(panel, -1, '', (120, 105))
        self.cb.SetValue(False)
        self.cb = wx.CheckBox(panel, -1, '', (200, 105))
        self.cb.SetValue(False)
        self.cb = wx.CheckBox(panel, -1, '', (278, 105))
        self.cb.SetValue(False)
        self.cb = wx.CheckBox(panel, -1, '', (356, 105))
        self.cb.SetValue(False)


        wx.StaticText(panel, -1, "Send output to File", (70, 255))
        self.cb = wx.CheckBox(panel, -1, '', (50, 255))
        self.cb.SetValue(True)

        wx.EVT_CHECKBOX(self, self.cb.GetId(), self.ShowTitle)

        self.btnSelect = wx.Button(panel, label="Select All", pos=(45, 295))
        self.Bind(wx.EVT_BUTTON, self.OnSelectAll, id = self.btnSelect.GetId())

        self.btnUnSelectAll = wx.Button(panel, label="Unselect All*", pos=(173, 295))
        self.Bind(wx.EVT_BUTTON, self.OnUnSelectAll, id = self.btnUnSelectAll.GetId())

        self.btnApply = wx.Button(panel, label="Apply/Close", pos=(305, 295))
        self.Bind(wx.EVT_BUTTON, self.OnApply, id = self.btnApply.GetId())

        wx.StaticText(panel, -1, "* Note: 'Unselect All' button will not unselect storms that" '\n'
                  "   have already determined", (20, 350))

        self.Show()
        self.Centre()

    def ShowTitle(self, event):
        if self.cb.GetValue():
            self.SetTitle('checkbox.py')
        else: self.SetTitle('')

    def OnSelectAll(self, event):
        self.cb.SetValue(True)

    def OnUnSelectAll(self, event):
        pass

    def OnApply(self, event):
        selection = self.cb.GetValue()


app = wx.App(0)
MyCheckBox(None, -1, 'checkbox.py')
app.MainLoop()

Save checkboxes for later uses. I used self.cb_list in the following code.

import wx

class MyCheckBox(wx.Frame):
    def __init__(self, parent, id, title):
        wx.Frame.__init__(self, parent, id, 'Checking Options', size=(470, 400))
        panel = wx.Panel(self, -1)

        self.cb_list = []
        for pos in [(120,75), (200,75), (278,75), (356,75), (120,105), (200,105), (278,105), (356,105)]:
            cb = wx.CheckBox(panel, -1, '', pos)
            cb.SetValue(False)
            self.cb_list.append(cb)

        wx.StaticText(panel, -1, "Send output to File", (70, 255))
        self.cb = wx.CheckBox(panel, -1, '', (50, 255))
        self.cb.SetValue(True)

        wx.EVT_CHECKBOX(self, self.cb.GetId(), self.ShowTitle)

        self.btnSelect = wx.Button(panel, label="Select All", pos=(45, 295))
        self.Bind(wx.EVT_BUTTON, self.OnSelectAll, id = self.btnSelect.GetId())

        self.btnUnSelectAll = wx.Button(panel, label="Unselect All*", pos=(173, 295))
        self.Bind(wx.EVT_BUTTON, self.OnUnSelectAll, id = self.btnUnSelectAll.GetId())

        self.btnApply = wx.Button(panel, label="Apply/Close", pos=(305, 295))
        self.Bind(wx.EVT_BUTTON, self.OnApply, id = self.btnApply.GetId())

        wx.StaticText(panel, -1, "* Note: 'Unselect All' button will not unselect storms that" '\n'
                  "   have already determined", (20, 350))

        self.Show()
        self.Centre()

    def ShowTitle(self, event):
        if self.cb.GetValue():
            self.SetTitle('checkbox.py')
        else: self.SetTitle('')

    def OnSelectAll(self, event):
        for cb in self.cb_list:
            cb.SetValue(True)

    def OnUnSelectAll(self, event):
        for cb in self.cb_list:
            cb.SetValue(False)

    def OnApply(self, event):
        selection = self.cb.GetValue()
        for i, cb in enumerate(self.cb_list):
            if cb.GetValue():
                print('{} selected'.format(i))


app = wx.App(0)
MyCheckBox(None, -1, 'checkbox.py')
app.MainLoop()
