So every single time somebody presses a key or clicks a button or even moves your window, or even when a redraw is queued on the window, you want to check the internal state of the window and possibly "do something"? That sounds like a ridiculously bad design to me, personally.Just call the function whenever state might change.

The function checks the state of the application and does something accordingly. Because any code in an event handler may potentially change the state of the application, a quick method is adding the function as the "after" handler for every event.2014-07-23 22:26 GMT+08:00 Jasper St. Pierre <jstpierre@xxxxxxxxxxx>:Why, though? Why do you need this?--On Tue, Jul 22, 2014 at 9:40 PM, Gang Chen <gang.chen.cn@xxxxxxxxx> wrote:
Yes, I need an "after" handler for every event. We can think it is called at the bottom of all event handlers. The function should be called not only after my own event handlers but also the widgets' event handlers.

I think he wants the equivalent of an "after" handler for "event". If he wanted a "before" handler for "event", I believe that already works (it does in GTK+2, anyway)
