Re: Are handlers kept registered on PopupPanel when we call hide() on it ?

Re: Are handlers kept registered on PopupPanel when we call hide() on it ?
It looks like the issue is not really the PopupPanel but rather the widget(s) you add inside: if you reuse the same widget (either in a single PopupPanel that you hide/show, or within several PopupPanel-s during the lifetime of the application), then handlers won't be unregistered for you, just like for any other widget (the same goes for the CloseHandler attached to a PopupPanel: PopupPanel is a widget like any other –except you don't add it to a parent widget–, so handlers aren't unregistered automatically). If on the other hand you re-create everything from scratch every time, then you'll obviously have to register your handlers on the new instances. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Are handlers kept registered on PopupPanel when we call hide() on it ?
Hi, I was wondering how this is working. I made some code where I registered some event handlers on a PopupPanel so I can keep the data up to date. But when I call hide on this popup panel and recreate a new one, then handlers are registered 2 times and so events are handler 2 times. I was expecting another behavior : when the popup panel is hidden, I thought it was some kind of destroy. So I think that my strategy to rebuild a new PopupPanel is not good. Can you explain me how this should be designed please ? Many thanks in advance. Boris -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
