Is it possible to pass arguments into event bindings?

by

You can always use a lambda or another function to wrap up your method and pass another argument, not WX specific.

b = wx.Button(self, 10, "Default Button", (20, 20))
        self.Bind(wx.EVT_BUTTON, lambda event: self.OnClick(event, 'somevalue'), b)
def OnClick(self, event, somearg):
        self.log.write("Click! (%d)\n" % event.GetId())

If you’re out to reduce the amount of code to type, you might also try a little automatism like:

class foo(whateverwxobject):
    def better_bind(self, type, instance, handler, *args, **kwargs):
        self.Bind(type, lambda event: handler(event, *args, **kwargs), instance)

    def __init__(self):
        self.better_bind(wx.EVT_BUTTON, b, self.OnClick, 'somevalue')
