EVT_SPIN_UP and EVT_SPIN_DOWN events don't work with wx.SpinButton

Hi,

I’m trying to bind some functions when up/down arrow buttons are clicked on a wx.SpinButton widget. I tried the following but nothing happens when I click up/down arrow button, what is wrong here:

import wx
import wx.lib.masked as masked

    h = self.time12.GetSize().height

Hi Steve,

The below works.
I modified Mike Driscoll’s wx.SpinButton example to handle spin up and down events.
See: http://www.blog.pythonlibrary.org/2010/06/10/wxpython-a-tour-of-buttons-part-2-of-2/
Yes, I am aware there is a mixture of old and new binding methods.

Bruce

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.TextCtrl(panel, value="1")
    self.spin = wx.SpinButton(panel, style=wx.SP_VERTICAL)
    self.spin.SetRange(1, 100)
    self.spin.SetValue(1)

    self.Bind(wx.EVT_SPIN, self.OnSpin, self.spin)
   
    self.spin.Bind(wx.EVT_SPIN_UP, self.on_spin_up)
    self.spin.Bind(wx.EVT_SPIN_DOWN, self.on_spin_down)

    vSizer = wx.BoxSizer(wx.VERTICAL)
    sizer = wx.BoxSizer(wx.HORIZONTAL)
    sizer.Add(self.text, 0, wx.CENTER)
    sizer.Add(self.spin, 0, wx.CENTER)
    vSizer.Add(sizer, 1, wx.CENTER)
    panel.SetSizer(vSizer)

def OnSpin(self, event):
    self.text.SetValue(str(event.GetPosition()))
   
def on_spin_up(self, event):
    print "up"

def on_spin_down(self, event):
    print "down"

Run the program

if name == “main”:
app = wx.App(False)
frame = MyForm()
frame.Show()
app.MainLoop()

Thank you, Bruce
