wx.EventBlocker

This class is a special event handler which allows discarding 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
    with wx.EventBlocker(self) as blocker:

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

    # wx.EventBlocker destructor called on exit from the context
    # manager, old event handlers are restored.

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