Method to get style range at the current position.

Hi Tomas,
I came across this use case. I can make a method for it, but I thought of letting you know in case you think it is worth integrating as a general purpose method.

The method would the range(start and end) of the style at a current position.

steps would something like this:
get the style at the caret position
get the boundaries of the style from the caret position: start range of style (left of caret) and end range of the style (right of caret).

Once I get that range, I can then apply additional styling. not only for that location, but for the whole range of characters to its left and right of it.

Hi Maher,

I could add such a method, I'm just not quite convinced about its general usefulness.

The use-case you mention can get more tricky. Imagine, for example, that you have the word
anti-oxidants
with caret positioned in the "oxidants" part. Imagine that you want to turn off the bold face. The method you suggest would return the range for the part "-oxidants" (since anti has a different style), thus resulting in
anti-oxidants
instead of
anti-oxidants.

Hi Tomas, sorry writing late. This is a use case that would benefit from such a method. I managed to make a sketchy method that does the detection.

Use case description:
Precondition: Have a number of saved CSS styles.
Purpose: iterate through the styles over text.

Steps:
Step0: save styles to a "gallery".
Step1: make a text selection ... or click somewhere in text and the code will detect the span based on the caret position.
Step2: scroll the mouse wheel , which will change the style of the selected text or the detected span as per the saved styles.

You should now be able to use

IndexRange range = area.getStyleRangeAtPosition(area.getCaretPosition());
area.setStyle(range.getStart(), range.getEnd(), newStyle);

Thanks :)
I will remove my patchy method now and that one liner of yours!
