[Seaside] How to display a busy.gif ?

The code on seasidehosting.st looks like this:

renderButtonsOn: html
	html div
		class: 'buttons';
		with: [
			html submitButton
				disabled: self isQuotaExeeded;
				onClick: (html element
					id: 'spinner';
					show);
				onClick: 'return true';
				on: #upload of: self.
			html submitButton
				on: #close of: self.
			html image
				id: 'spinner';
				style: 'margin-left: 5px; display: none;';
				extent: 16 @ 16;
				url: '/resources/pics/spinner.gif' ].

Since this does a full page refresh it is automatically disabled after
the refresh of the page. If you combine it with an AJAX action simply
add a hide effect to the onComplete: event.

Hope this helps,
Lukas
