laszlo equiv of body onload?

[whisperstorm]

I want to execute some code after all the data has loaded and everything's ready to go. If I were in HTML I'd have an onload handler on the body tag, what is the equiv for a laszlo app? ininit on canvas?

Not quite - oninit on canvas will fire after all the views are in place (but before any initstage="late" views have finished initing).

Data requests are completely asynchronous. The only way to find when they come back in is to create <datapointers> into the canvas that point into the datasets that you want to wait for. Then put a method that's tied to the ondata event into each of those datapointers, and have them register with some global variable, and check if they're the last one to be returned.
