Hi,
I have a custom text widget (essentially just a <textarea> inside an
iframe) and I need to set the focus on the iframe in order to update the
cursor position in the textarea. I can call textarea.focus() from my
javascript but I think the iframe itself needs to have focus for the
textarea element to update.
In other words I need to simulate a mouse click on the textarea - the
line only update works after I click inside the textarea!
Does anyone know how to achieve this?
Thanks,
Mike

Hi Mike,
did you try to put the EditArea in a qooxdoo div (e.g.
CanvasLayout)? The gmaps example in the custom widget tutorial does
this. The tutorial can be found here:
http://help.eclipse.org/help33/index.jsp?topic=/org.eclipse. rap.help/help/html/advanced/custom-widget.html
The most recent version of this document is available in the tooling
download.
Cheers,

Mike,
as far as I know a this doesn't force you to use an ifame. But I am
not Javascript expert at all. You may just give it a try or ask on
the experts from the qooxdoo mailing-list.
Cheers,
Rüdiger
