AutoScrolling Performance

Thanks Richard,

I am going to need to get that to work.  I looked at the code and saw that in BaseCompose composeTextFlow there is a line: _curElement = _rootElement.getFirstLeaf(); which sets the start point of the composition.  I was thinking of extending ComposeState, and StandardFlowComposer to add some functions that would just compose from a certain point.  However when I started to do this and compile against the 427 build that I was using as my swc I realised that it was not going to work because I don't think that ComposeState existed in that build.  I tried to compile against two later builds: 470, and 502 - but in those, before even building in any extra classes, the code that I wrote for the example above doesn't work as I expected.

In 427 this code:

cc = new ContainerController(text_container, 400, 200);

cc.verticalAlign = VerticalAlign.BOTTOM;

will cause the text to automatically scroll after new text is added and updateAllContainers is called.

eg:

var d:DivElement = new DivElement();

var p:ParagraphElement = new ParagraphElement();

var span:SpanElement = new SpanElement();

span.fontSize = Math.round(Math.random() * 10) + 8;

span.fontWeight = (count%3 == 0)? FontWeight.BOLD :FontWeight.NORMAL;

span.text = "Count " + String(count) +" a line of text or two goes here a line of text or two goes here a line of text or two goes here";

p.addChild(span);

d.addChild(p);

text_flow.addChild(d);

text_flow.flowComposer.updateAllControllers();

In the later versions it doesn't seem to align the bottom of the text to the bottom of the container. 

I haven't tried to see why, first I wanted to know if this is a bug or expected behavior.

I also wanted to know which build I should work with if I extend these classes. 

Thanks again for your help,

Josh
