Event to trigger *after* canvas has finished resizing

[iainc.dev]

The canvas class has a method "addresizehandler()" which allows one to trigger code when the canvas is resized. However, during a normal resizing event, this seems to get triggered many times. Is there a way to trigger the code only after the user has **finished** resizing the canvas? Presumably, one would need some sort of threshold, such as "x miliseconds" (where x could be 2000), to determine whether the user has actually finished resizing the event. Or, is there a better way such as detecting that the user has stopped pressing down on the mouse. I couldn't find any method such as "afterResized".

[Isomorphic]

If you're talking about reacting to a live drag resize (dragAppearance:target) on that Canvas, dragStop fires at the end of the drag.

If there's some other, more indirect trigger, there's no general way that a widget can know that resize isn't going to be called anymore - you would just need to write code that sets and resets a timer so that your action takes place X milliseconds after the last resize.
