Subject Re: Adding font properties to a TextArea
Date Tue, 01 Jun 2010 23:16:22 GMT
This may not actually be that tough. TextArea currently provides a getCharacterBounds() method
- you can determine the bounding area of the range you want to highlight by calling this method
for the first and last character in the range. Note that the highlight shape may not always
be a rectangle - when text wraps, your highlighted area may span multiple lines. However,
handling this condition is also not terribly difficult.
