Dear all,

is it possible to change the size of the hover that Xtext provides? In our project, we are presenting quite some information in the hover, and it is somewhat awkward that the user has to focus the hover to see all information by scrolling.

Optimal would be adjusting the size to the information that is displayed, alternatively changing the fixed size would be OK.

Thanks,

Andreas

Did you try to customize AbstractHover.getHoverControlCreator

I am not quite sure where to put the size there. Should I implement my own getHoverControlCreator() and my own implementaion of DefaultInformationControl?

Hi the DefaultInformationControl may already have size properties you
can customize I guess. But for details you should have a look into
the code yourself. Subclassing DispatchingEObjectTextHover should be
done in minutes.

There seems to be a bug in the eclipse hover control where it doesn't calculate the size of <pre> blocks properly. There are probably some other cases it doesn't handle well either.

To see this try creating a java file and use a <pre> block in your javadocs, then hover over the element to see what your <pre> block looks like. For me at least, with eclipse juno on Windows 7, the hover popup is too small.

... thus the workaround here is to avoid using markup like <pre> that screws up the size calculations ...
