WTextArea::addText(const WString &text)
I'm missing some method for adding text to text area. It can be useful when the text is long and thus using textarea~~setText(textarea~~>text + mytext) may be inefficient (the original long text is going to server, there is appended a short one, and then is whole text sent back to client).
I want use the text area as a some log.
Btw what is the maximal length of the text. If I use it as the log, then I should delete the oldest entries and there isn't any client side method too.
