Re: [Dynapi-Help] createTextRange

[Leif W <war...@us...>]

Hi, I'm trying to give this a shot, but am stuck on some DOM2 event handling
stuff.  Basically in Opera there's no text ranges, so we need to kludge some
other way to convert mouse coordinates to text coordinates within a
textarea, then if we could just do that, it's pretty easy to write string
based insert functions.  I was thinking if we could use a DOM2 MouseEvent
tied to the TextArea, and access clientX and clientY (but not sure if
they're specific to the TextArea like I am thinking, or to the document like
I am hoping is not the case, as then we have to find and compensate for the
offset of the TextArea), then we might have a chance of concocting some
cocamany algorithm for converting font size pixels back to text coords.  May
need some restrictions on the editor, like a fixed-width font in the
textarea, (at least to simplify the prolem in the beginning) or else the
algorithm just relies on averages and hopes for the best.  I know it's a
longshot, but what other alternatives might there be?  Could a Java plugin
compensate for a browser's lack of DOM TextRanges by getting access to the
correlating the mouse position, over a TextArea, when selecting, start and
end coordinates of text characters within the TextArea's string?

if i put it into the library and maybee we make a new folder/part of the

its not a widget or a component in other cases.
