Flex/FlashBuilder4 裡 htmlText 的實現

t isn’t immediately obvious how to display HTML text in a Spark TextArea. Back in the MX days we had textArea.htmlText which is pretty easy to use. But no such beast on the Spark version.

With a Spark text component you have to run your HTML text through a multi-dimensional phase-inducer which is handily provided through spark.utils.TextFlowUtil.importFromString( myHTMLtext );

But you don’t send the output of the importFromString method to the textArea.text. No, no, no. That would be toooo easy. With Spark there’s a new thingy called textFlow. That’s what gets the output of the importFromString()
method.

Here’s a very simple example

myTextArea.textFlow = spark.utils.TextFlowUtil.importFromString('some <span fontWeight="bold">bold</span> text.' );
