eclipse scout image change - image

Question

I am trying to change image inside Image view.
I know that getTestImageField().setImageId(Icons.Logo); would not work, because it would not refresh renderer.
Because I need to use setImage(), I need a way to get Image from Icons class.
As Patrick suggested I try
final IconProviderService provider = SERVICES.getService(IconProviderService.class);
final IconSpec ic = provider.getIconSpec(AbstractIcons.StatusError);
final byte[] content = ic.getContent();
but my problem is that ic is always null.
While I debug this I notice that inside IconProviderService.class in line 57 :
#Override
protected URL findResource(String fullPath) {
URL[] entries = FileLocator.findEntries(m_hostBundle, new Path(fullPath));
if (entries != null && entries.length > 0) {
URL url = entries[entries.length - 1];
if (LOG.isDebugEnabled()) {
LOG.debug("find image " + fullPath + " in bundle " + m_hostBundle.getSymbolicName() + "->" + url);
}
return url;
}
return null;
}
URL[] entries is always empty no matter witch icon I try to present.
After further debugging I found out that FileLocator tries to find fragments from bundle, and then look for the path inside this fragments. (line 242)
Bundle[] fragments = activator.getFragments(b);
but Bundle[] fragments is always null.
Normally my bundle b is (Bundle) EquinoxBundle : org.eclipse.scout.rt.ui.rap.mobile_4.0.100.20140829-1424.
I want to try with different bundle so I do :
final BundleContext context = Activator.getDefault().getBundle().getBundleContext();
for (final Bundle b : context.getBundles()) {
final IconProviderService provider = SERVICES.getService(IconProviderService.class);
provider.setHostBundle(b);
final IconSpec ic = provider.getIconSpec(AbstractIcons.StatusError);
if (ic != null) {
final byte[] content = ic.getContent();
imageField().setImage(content);
}
}
but fragments (from above code) is always null.

You can obtain the image content (byte[]) that you can set on the image field as follows:
IconProviderService provider = SERVICES.getService(IconProviderService.class);
byte[] content = provider.getIconSpec(Icons.YourIconName).getContent();
getImageField().setImage(content);
I quickly checked it and it works for me.
Please ensure that the icon is available and you set up the icon provider service as explained in this Wiki Article
