For TextInput and TextArea:

// to check for any selected text:
var hasSelection:Boolean = (component.selectionBeginIndex!=component.selectionEndIndex);
// to get the selected text:
var selection:String = component.text.substring(component.selectionBeginIndex,component.selectionEndIndex);

For RichTextEditor:

// to check for any selected text:
var hasSelection:Boolean = (component.selection.beginIndex!=component.selection.endIndex);
// to get the selected text:
var selection:String = component.selection.text;

This will check if the component has any selected text, but not whether the component is selected; the text selection stays even when the component loses focus. The easy way to check if the component actually has focus is by setting a boolean flag in the component’s focusIn and focusOut events. You could also deselect the text in a focusOut event:

component.selectionEndIndex = 0; // clear selection
