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,
I don't know of any way to simulate a mouse click. But you might be
better of asking the experts at qooxdoo (http://qooxdoo.org).
As I know of many implications when using an IFRAME, I would
recommend to not use this element if ever possible.
If that doesn't help, maybe you could explain in greater detail what
you want to achieve?
Cheers,

a Java applet to run client-side simulations, so I've had to use another
iframe for that. I'm quite new to web development so I wasn't really
aware of the issues in using iframes. Do you know of any alternatives?
Thanks for your help.

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,
Rüdiger

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.

Rüdiger
