[DataBinding] TableViewer - ViewerSupport: render converted text or image [message #633337]

Hi,

I use ViewerSupport to bind a List of elements (WritableList) to a
TableViewer. The ValueProperties are 'generated' using
BeanProperties.values(). Everything works well, but I have two issues:

1. How can I change the output of an element in the list? (E.g. I have
BigDecimals that have to be shown with two digits and a currency symbol.)
2. How can I render a field with an image? (E.g. a boolean value should
be show as red or green icon.)

Maybe you have any links or information that I can use to solve that issue.

Thanks.

(Up to now I couldn't find a solution using google or newsgroup search.)

Hi,

ViewerSupport doesn't work for your usecase and you need to setup a
things your own.

Here's an implementation of a LabelProvider:
http://dev.eclipse.org/viewcvs/index.cgi/org.eclipse.emf/org .eclipse.emf/examples/org.eclipse.emf.examples.databinding.p roject.ui.rcp/src/org/eclipse/emf/example/databinding/projec t/ui/rcp/databinding/GenericMapCellLabelProvider.java?view=m arkup&root=Modeling_Project

and an example on how to set it up:
http://tomsondev.bestsolution.at/2009/06/27/galileo-emf-data binding-part-5/

which use EMF-Databinding but that shouldn't matter and you should get
an idea how to setup a TableViewer.

Hi,

thanks. so I'll try to implement it on my own :-). At least I've already
done that stuff with databinding.
