Answer 1

you need to set your max to 8 so that you can get a big enough number and listen to EVT_TEXT

import wx

class MyForm(wx.Frame):

    def __init__(self):
        wx.Frame.__init__(self, None, wx.ID_ANY, "Spin Button Tutorial")
        panel = wx.Panel(self, wx.ID_ANY)

        self.text = wx.SpinCtrl(panel, value="1")
        self.text.SetRange(1, 8)
        self.text.SetValue(1)

        self.text.Bind(wx.EVT_SPINCTRL, self.OnSpin)
        self.text.Bind(wx.EVT_TEXT, self.OnSpin)



    def OnSpin(self, event):
        if self.text.GetValue() > 7:
               self.text.SetValue(7)
               wx.MessageDialog(self,"Test Message","Too Big!").ShowModal()

# Run the program
if __name__ == "__main__":
    app = wx.App(False)
    frame = MyForm()
    frame.Show()
    app.MainLoop()
