Are Gallery Items adaptable? [message #549910]

I am just wondering if it is possible to adapt a gallery item to another type.

Here are snippets from my implementation.

I have set breakpoints in all of these methods and do not get into any them when debugging. I am working from examples in other portions of our product which do work, so am kind of perplexed as to what I might have wrong (if anything). Or if this is even supported by the Gallery.

in my plugin.xml file

<extension
point="org.eclipse.core.runtime.adapters">
<factory
adaptableType="com.xxx.yyy.results.ResultsGalleryItem"
class="com.xxx.yyy.results.ResultsGalleryItemAdapterFactory ">
<adapter type="com.xxx.yyy.results.RG"/>
</factory>
</extension>

AdapterFactory class

public class ResultsGalleryItemAdapterFactory implements IAdapterFactory
{
public Object getAdapter( Object adaptableObject, Class adapterType )
{
if ( adapterType.equals(com.xxx.yyy.results.RG.class) )
{
if ( adaptableObject instanceof ResultsGalleryItem )
{
ResultsGalleryItem t = ( ResultsGalleryItem )adaptableObject;
return t.getAdapter(adapterType);
}
}

return null;
}

public Class[] getAdapterList()
{
return new Class[] { com.xxx.yyy.results.RG.class };
}
}

In ResultsGalleryItem, which implements IAdaptable

public Object getAdapter(Class adapter) {
if( (com.xxx.yyy.results.RG)getData() != null
&& adapter.isAssignableFrom( com.xxx.yyy.results.RG.class ) )
{
return getData();
}

return null;
}

Hi Rick,

Gallery is an SWT component so it does not use classes from RCP :
GalleryItem does not implement IAdaptable.

You can still attach your own adaptable objects to GalleryItems using
setData() / getData().
