GWT Composite open/visible Handler

[ph09]

Hello,

I have got several Composite and I would like to add an Handler to one of them which fire an event when the user open this composite. Is there any Handler for?

Thank you..

Doesn't the user use something to make this composite visible?  Like some kind of control?  Why not just fire an event from there?

Hmm, ok I explain it in another words. I have got a tab with several Composites on it.When a user click on one of them, the Composite is shown to the user. In this Case I would like to start a method, but I doesn't know if there is any Handler for..

So why not add a handler on the the the tab being selected?
