Read-only RichTextArea?

[Elchin]

Is there a way to make RichTextArea read-only like TextArea.setReadOnly
(true)?
What I need in my application is the possibility to edit the rich text
only by buttons in toolbar, and not through typing.

[Elchin]

One way would be catching all events, and redoing them, but that is a
big time hassle, I wonder if there is any way to do it from DOM?

You can try something like this this:
DOM.setElementPropertyBoolean(getElement(), "disabled", <true or
false>);

You can try setting on/off the iframe designMode attribute , something like this.

   RichTextArea area = new RichTextArea();

   setEnabled(area.getElement(), false);

   native void setEnabled(Element iframe, boolean b) /*-{
       iframe.contentWindow.document.designMode = b ? 'On' : 'Off';
    }-*/;

It works for ff and webkit, ie seems not working.

This method also works in IE

    private native void setEnabled(Element iframe, boolean b) /*-{
       var doc = iframe.contentWindow.document;
       if (doc.body.contentEditable)
           doc.body.contentEditable = b;
       else
           doc.designMode = b ? 'On' : 'Off';
    }-*/;

com.google.gwt.core.client.JavaScriptException: (TypeError):
iframe.contentWindow is null

What do you think might be causing this null pointer exception ?

I also came into that problem... BTW there's already a setEnabled function that should work, but doesn't... I'll check issues and report that if it's not already.
