Hello

I want to implement a kind of assistant, which is a dynamic yellow frame to display information about the rule or type while coding.
For instance ,it has to be ;
when the mouse indicates on a particular type,the frame has to come up dynamically and display information just like javadocs,

I need some clues, look forward to hear back

Hi,

am note quite sure but this works out of the box using Xtext 2.0.0. see e.g. http://ckulla.wordpress.com/2011/02/06/hover-support-in-xtext-2-0/
you have basically to implement IEObjectDocumentationProvider afaik

you basically just need to extend DispatchingEObjectTextHover and overwrite the method getHoverInfo(...).

It took me a while to find out how to bind the extended class:

Generate a class MyDslCompositeHover, copy the contents of DefaultCompositeHover and change the inject of htmlHover to your own EObjectTextHover

Finally add this to MyDslUiModule

public Class<? extends org.eclipse.jface.text.ITextHover> bindITextHover() {
return MyDslCompositeHover.class;
}

That's what I'm using, it works fine Smile

Thank you so much Timo, I was still searching,
There are some articles which are written min. 1 year ago.
However, I couldn't find any tutorial/article about Hover implementation with X Text 2.0
please if you know, share with me.
Now i will try to do your suggestion and come back Wink
