I'm new to flex, actually I'm reading a simple tutorial about Flex 4 (I'm using flash builder 4.5) this is the tutorial.
I added a RichEditableText and then I should specify the property selectionColor, but when I add it to the source code, the IDE give me an error like this property do not exist.
<s:RichEditableText x="179" y="95" text="hello" fontSize="24" fontWeight="bold" color="#E52222" selectionColor="#000000" />
The property is slightly different now. It's focusedTextSelectionColor There's also an unfocusedTextSelectionColor. The article you are reading is for a Flex Gumbo Pre-Release. That's basically a beta version of 4.0 and now we're on the 4.5 SDK so there are slight differences. Here is a good tutorial from FlexExamples: http://blog.flexexamples.com/2009/11/07/setting-the-selection-highlight-color-on-a-spark-richeditabletext-control-in-flex-4/
