Is there an activity indicator in Wicket?

问题

I'll make this short:

Is there a way / library in Wicket to show an activity indicator? You know, the spinning thing that moves while the user is waiting for something, or is it just a javascript thing?

Thanks for your help.

回答1:

If this is an ajax operation then you can look at the implementations of IAjaxIndicatorAware. These implementations will show a 'spinner' while the operation is processing.

e.g. IndicatingAjaxButton and IndicatingAjaxLink

You could also look at AjaxIndicatorAppender and alter it your own needs for non ajax things ?

Check here to generate your own 'activity indicator'.

Simply show it when busy & hide it afterwards.
