Hi.

My code is:



When I click the button, I get a segmentation fault.


Thanks.





Edit: I solved it. I override the old event by the new event





Edit 2:

Finally, I needed to use a "deadlist". When a Button was clicked, its event was pushed back in the list. The list was updated (cleared) every frame.

Hi,

The 'removeAllEvents' function actually removes the event objects themselves as opposed to subscribed handlers

I'm also not sure if the 'fix' is what you want - since it leaves the original handler function connected also - so every time it's clicked, you get another copy of the second handler added; it will subsequently be invoked multiple times

The current 'correct' method to disconnect an event subscriber is to save the connection object returned when you subscribe, and later call the 'disconnect' member function on that connection to disconnect.

HTH

You are right. When I click button, multiple events are executed. Im go to use "disconnect". Thanks.

I have this code now:



However, the program ends with segmentation fault. Is it possible that a Event disconnects itself?

Hi,

I should have spotted the deliberate mistake last night, though it was late and I was knackered

Currently there are issues when disconnecting event subscribers from within a subscriber attached to the same event priority queue. The main reason this is the case is because it messes up the STL iterator used to iterate over subscribers.

What you might have to do is maintain a 'dead list' of connections to be removed at the end of the frame (or something).

Sorry about the confusion
