Split and Merge Paragraphs

When I split and merge a paragraph a line break is inserted.  Does anyone know a way around this. (Simply deleting the last character seems inelegant and, more importantly, prone to failure).  Here's the code:

var textFlow:TextFlow = TextConverter.importToFlow(
                    "Hello World",
                    TextConverter.PLAIN_TEXT_FORMAT);
textFlow.interactionManager = new EditManager();
var textFlow2:TextFlow = textFlow.splitAtPosition(5) as TextFlow;
textFlow2.interactionManager = new EditManager();
textFlow.mxmlChildren = textFlow.mxmlChildren.concat(textFlow2.mxmlChildren);
trace(textFlow.getText()); // returns "Hello\n World"

Correct answer rdermer

If you are asking how to split and merge a paragraph this works.

            var textFlow:TextFlow = TextConverter.importToFlow("Hello World",TextConverter.PLAIN_TEXT_FORMAT);
           
            // find the paragraph
            var para:ParagraphElement = textFlow.findLeaf(5).getParagraph();    // same as textFlow.getChildAt(0)
            // split paragraph at position five
            var newPara:ParagraphElement = para.splitAtPosition(5) as ParagraphElement;
            trace(textFlow.getText());
           
            // now the merge
           
            // remove newPara its being discarded
            newPara.parent.removeChild(newPara);
            // move the children
            while(newPara.numChildren)
                para.addChild(newPara.getChildAt(0));
           
            trace(textFlow.getText());

This is using pure model level calls.  In your original code you added an EditManager- it can be done that way too.  TLF is layered - the EditManager manipulates the model with model level calls.  It provides APIs connected to events that create operations do to that.

Hope that helps,

There's no merge here.  When you assign mxmlChildren at the end the result is two paragraphs.  getText is inserting a paragraph separator which defaults to a newline.

BTW using mxmlChildren isn't recommended - that method exists for the support of the mxml compiler. Better to use replaceChildren.

Hope that helps,

I understand that this is the problem.  I'm trying to figure out how to solve it using a comprable method.  Cut and Paste through EditManager doesn't seem to help.  Is there any other method out there?

We recently added a getText() function to FlowElement, which has a parameter for the paragraphSeparator -- in this case, it's a separator, not a terminator, so you will get one between elements but not at the end.
