update a component via onMouseOver:

Hello all,

i would like to update aComponent via onMouseOver:
I?ve tried several things (triggerFormElement: and so on), but nothing
works.
Updating something in the same Component is no problem, but updating
another Component doesn?t work.

For example, i?ve tried:
onMouseOver: (html
updater id: 'previewId';
triggerFormElement: 'attributePreview')

I?ve got a Component with a form called "attributePreview". The
renderContentOn: will be called, but nothing happens, no update.
Are there any examples available on this topic?

Any ideas?
Cheers
Marco

I would not recommend to use onMouseOver: nor any event from tag's attribute
(read: http://www.prototypejs.org/api/event/observe).

>From Seaside you access that with anElement>>on: anEventString do:
aHandlerObject
With prototype you can even use your own custom events like this: anElement
fire: 'mouse:enter'

Hi,

2008/8/20 Marco Leberfing <[hidden email]>: I think you have to use the rendering callback here... osmething like:

onMouseOver: (html
       updater id: 'previewId';    "the div id that will be redraw
with the rendering callback associated here "
       triggerFormElement: 'attributePreview');   "trigger the action
associated to the form element 'attributePreview' callback
       callback: [:renderer | "some optional actions" . self
renderUpdateAttributePreviewOn: renderer])

Just search for senders of #updater and see examples. If you have a
squeak-web image, there should be plenty.
