Showing link inside custom hover (Eclipse plugin development) - eclipse-plugin

Question

I have a custom hover inside CDT editor (see the linked SO question) and now I want to show link inside my IAnnotationHover hover:
public class MyAwesomeHover implements IAnnotationHover {
#Override
public String getHoverInfo(ISourceViewer sw, int ln) {
return "<a href='www.stackoverflow.com'>so</a>"
}
}
Unfortunately the link is not shown - the hover window shows only simple text (i.e "so"). Other HTML elements I tried work OK (ul, li, p, font ...). Can anyone help me please?

As was mentioned in the comments, the RevisionHover was a good starting point. The magic is in implementing the IAnnotationHoverExtension and creation of a custom AbstractReusableInformationControlCreator. I am posting a code snippet with solution that worked for me.
public class MyHover implements IAnnotationHover, IAnnotationHoverExtension {
...
#Override
public IInformationControlCreator getHoverControlCreator() {
return new MyCreator();
}
...
#Override
public Object getHoverInfo(ISourceViewer sv, ILineRange lr, int vnl) {
return "<a href='www.stackoverflow.com'>so</a>";
}
...
private final class MyCreator extends AbstractReusableInformationControlCreator {
protected IInformationControl doCreateInformationControl(Shell parent) {
BrowserInformationControl control =
new BrowserInformationControl(
parent,
JFaceResources.DIALOG_FONT,
false);
control.addLocationListener(
new LocationAdapter() {
#Override
public void changing(LocationEvent ev) {
if (ev.location.startsWith("file:")) {
// !This opens the link!
openUrl(ev.location)
}
}
});
return control;
}
}
}
