[Moose-dev] Re: Animated grid visualisation

Yes, this script is probably the most inefficient way to implement this. On my machine, there is a pause every 9 seconds approx. Consider this slightly modified script: | v anim | v := RTView new. shape := RTBox new color: [ :o | Color random ]; size: 25. anim := RTActiveAnimation new. anim intervalInMilliseconds: 100. anim blockToExecute: [ |e| v clean. (1 to: 400) do:[:i| e := shape element. v add: e]. RTGridLayout new gapSize:0; lineItemsCount: 20; on:v elements. ]. anim inView: v. ^ v Shape are reused and not created each time. Again on my machine, the pause occurs after ~15 seconds. Removing, creating and adding elements at each refresh is not efficient at all. You can simply update the property of the element by either sending #updateShape or directly modifying the trachel shape. In that case, you need a model and the element reflect the property of the model. There is no need to recreate elements all the time. Cheers, Alexandre
