How to use IResourcePool [message #804103]

I'd like to know how to use IResourcePool.

I can inject IResourcePool, but don't know how to set resources.

I read the source code.
It seems it (eventually?) calls an OSGi Service and uses IResourceProviderService's properties to get resources.

Do I have to implement IResourceProviderService and it's properties in my app?
Or is there an easy way to set resources?

It would be great if I can get resources from preference setting.
(by Color: rgb,Image: uri, Font: fontname etc)

Thank you in advance. Smile

No - currently the only way is to provide an OSGi-Service but you are
free to grab the sources and implement new features, provide a patch and
we can discuss if this feature is feasable.

There is a base class available which you can simply subclass
(BasicResourceProvider) and use DS to contribute.

An example can be found here:

http://git.eclipse.org/c/e4/org.eclipse.e4.tools.git/tree/bundles/org.eclipse.e4.tools.emf.ui

That would be a nice addition for a base class which queries the
preference store for a value.

Thank you very much for the quick reply.

It seems org.eclipse.e4.tools.emf.ui.internal.ResourceProvider just defines properties as String.
So I made an empty subclass of BasicResourceProvider and set the service's properties entry to preference setting file.

like this,

<properties entry="preferences.ini"/>

I don't know if this is the correct way, but it works for now.
