EventBlocker

This class is a special event handler which allows to discard any event (or a set of event types) directed to a specific window.

Example:

def DoSomething(self):
    # block all events directed to this window while
    # we do the 1000 FunctionWhichSendsEvents() calls
    blocker = wx.EventBlocker(self)

    for i in xrange(1000):
        FunctionWhichSendsEvents(i)

    # wx.EventBlocker destructor called, old event handler is restored

    # the event generated by this call will be processed:
    FunctionWhichSendsEvents(0)
