Updating a textFlow

Hi everyone,

How can i update a textFlow?

i create a TextFlow like this :

var ca:TextLayoutFormat = new TextLayoutFormat();

ca.fontLookup = FontLookup.EMBEDDED_CFF;

var container:Sprite = new Sprite();

addChild(container);

var textFlow:TextFlow = TextConverter.importToFlow(_markup, TextConverter.TEXT_LAYOUT_FORMAT);

textFlow.hostFormat = ca;

textFlow.flowComposer.addController(new ContainerController(container, 400, 200));

textFlow.flowComposer.updateAllControllers();

_markup is a XML and i want to replace _markup by another XML without removing the textFlow. How can i do this?

Thanks.

Easiest way that I've found is to use the TextConverter to create a second TextFlow with the new markup. Then

replace the children in the original TextFlow with the children from the new TextFlow, and copy the properties over.

Thanks for your answer.

Your method is more a hack than a solution. I mean that's cool, it does visually what i want but i can't believe there is not a real update method.

Anyway thank you again, i'll use your method until i find a real solution.

You can use this:

var selState = new SelectionState(textFlow, 0, textFlow.interactionManager.absoluteEnd);
EditManager(textFlow.interactionManager).deleteText(selState);
EditManager(textFlow.interactionManager).overwriteText("abc", selState);

If you just want to append content, just use:

EditManager(textFlow.interactionManager).overwriteText("abc");

[Edit]:

For some reason, the absoluteEnd gives -1 at times. However, we need the length of the text. Hence, use this:

var str = TextConverter.export(textFlow, TextConverter.PLAIN_TEXT_FORMAT, ConversionType.STRING_TYPE) as String;
var selState = new SelectionState(textFlow, 0, str.length);
EditManager(textFlow.interactionManager).deleteText(selState);
EditManager(textFlow.interactionManager).overwriteText("abc", selState);
