Can't you just use text: "Loading..." and make the three dots at the end cycle: ".", "..", "..."
I think most people will be styling the loading feature anyways, so in the core implementation it should be simple, easily stylable (by using font size, text color, etc). If you use an image than it either has to be replaced with something that matches the rest of the app or have to figure out how to modify the spinner graphic to match the color scheme of your app. So, I vote for a text based "Loading..." widget that cycles through dots. - lex On Sun, Jan 29, 2012 at 12:05 PM, Peter Bittner <[email protected]> wrote: > Okay, back to the agenda, ladies.
