Adding formated Span at current position

Hi,

I want to have an external button that will insert a formatted SpanElement at current position.

How can I insert my own elements in the required(cursor) position?

Element might look like:

var span:SpanElement = new SpanElement();

span.text = text; span.setStyle('custom',true);

span.color = '0xFF0000';

Thank you

Find the leaf element using texFlow.findLeaf. If the position to insert is in the middle of a span use splitAtPosition to split it in two.

Compute the index you want to add the new span at using parent.getChildIndex and now the replaceChildren API can insert your new span.

Hope that helps,

Richard

Hi Richard.

Your idea helped alot, but now I have another problem.

I think TextFlow merges the spans somehow. Any idea on that ?

Adjacent spans with identical attributes are merged when TLF recomposes the text. If you have a span that should not be merged, assign it an id.
