How to pass a parameter with an event binding?

I can't figure out how to pass a parameter with my
event binding. For example, suppose I want to pass the
name of the button that was just clicked. Normally I'd
do this:

self.button1 = wx.Button(panel, -1, label="Start")

self.Bind(wx.EVT_BUTTON, self.OnStart,
id=self.button1.GetId())

def OnStart(self, event):
....print "pressed!"

However, what if I wanted to pass a paramter to my
OnStart function. This is the gist of what I want to
do, but this doesn't work. Note the addition of the
"something" variable:

self.button1 = wx.Button(panel, -1, label="Start")

self.Bind(wx.EVT_BUTTON, self.OnStart("something"),
id=self.button1.GetId())

def OnStart(self, event, myvar):
....print myvar

TypeError: OnStart() takes exactly 3 arguments (2

given)

Any tips on this?

You could use an object property to hold the value you want passed,
something like this:

self.button1 = wx.Button(panel, -1, label="Start")
self.parameterVal = "something"

self.button1.Bind(wx.EVT_BUTTON, self.OnStart)

def OnStart(self, event):
....print self.parameterVal
