Re: Getting the RichTextArea to expand as you type
tried the other solution in this thread with visibility:hidden html widget... works but need white space on page and real estate issues as whitespace grows with the growing richtextarea, based on this reply, how can you know on keyup or keydown weather you have a scrollbar in RichTextarea which has become visible, so can start resizing? couldn't find any api to query?

Re: Getting the RichTextArea to expand as you type
sorry for the delay, anyway "myHTML" was a typo. Sorry about that.
You should do sth like
/* an GWT HTML you have to place somewhere in the page then
associate a css rule like visibility: hidden in order to make the
browser not showing it. */
HTML divHidden = new HTML();
...
...
...
public void onKeyUp(Widget sender, char keyCode, int modifiers) {
RichTextArea rta = (RichTextArea) sender;
divHidden.setHTML(rta.getHTML());
rta.setHeight(""+
(divHidden.getOffsetHeight()));
}

Re: Getting the RichTextArea to expand as you type
I had a lot of fun with this problem. My solution was to increase/
decrease the row attribute of the textarea as the user types. It's not
perfect but it behaves as expected and executes fast.
Source code for my widget here: http://pastie.org/635638
I'd be interested if you folks have any critiques or insights.
Hope this helps!

Can you post the whole solution. I'm unsure exactly how myHTML and
divHidden fit in.
Thanks.

Re: Getting the RichTextArea to expand as you type
I solved the issue by associating a keyboardlistener to the textarea
which copies
the textarea contents into a GWT HTML Element and get its height.
(Then you resize the textarea with the new HTML Element height)
in the keyboard listener you do sth like
public void onKeyUp(Widget sender, char keyCode, int modifiers) {
RichTextArea rta = (RichTextArea) sender;
myHTML.setHTML(rta.getHTML());
rta.setHeight(""+
(divHidden.getOffsetHeight()));
}
hope this helps.
M.
You should associate a css rule like visibility: hidden to the HTML
Element in order to make the browser not showing it.

Re: Getting the RichTextArea to expand as you type
Someone please answer, it is very important for me. I need it to expand only vertically and not horizontally I am thinking of adding an event listener for the keyboard and mouse and on each event I will check if there are scrollbars - if there are, I will increase the height, if there aren't I will decrease.

Getting the RichTextArea to expand as you type
I'm trying to use the GWT RichTextArea. I would like the size of the area to expand vertically as you type, so there is never a scrollbar.
