"Wait" screens

[johncorro]

Is there any way to automatically display a "Processing..." type dialog/window while some lengthy operation is being performed? For instance, I'm trying to build a base "DataView" that will display a "Processing..." dialog or window while an HTTP request is being made to do some CRUD operation. The operation on the server side could take a few seconds and I'd like to let the user know that the app hasn't hung on them.

Laszlo doesn't provide "automatic" wait screens, but
a simple example of one can be seen here (enter a search phrase to trigger the wait screen):

Perhaps the thing to do is extend the view class to provide a wait screen when its data is retrieved/refreshed.
