Question

Is it possible to pass additional arguments to an event callback?

For example, if my event binding looked like this;

self.Bind(wx.EVT_BUTTON, self.do_something, self.button) 

How could I pass the arguments to my method?

self.do_something(self,event,arguments):
    """do something with arguments"""
    pass

Answer 1

Use lambda:

self.Bind(wx.EVT_BUTTON, lambda event, args=args: self.do_something(event, args), self.button) 

self.do_something(self,event,arguments):
    """do something with arguments"""
    pass
