screen of the tooltip to remove

Displaying a tooltip with no information is quite useless, maybe it's better to do nothing.

See attached screenshoot.

The source code to modify is:
org.eclipse.dltk.internal.ui.text.hover.DocumentationHover.getHoverInfo(String, Object[]):464

I can also provide a patch for this bug if needed.

Hi Marc,

Empty tooltip is not that useful, I agree.
For me, current DLTK also displays element icon and name.
I think "no documentation" hint can be removed, keeping only element icon+name, like JDT does.
Makes sense?

Regards,
Alex

Hi Alex,

Thanks for your quick response.

In JDT the tooltip show the scope, the visibility and the type of the hovered item. But in dynamic languages, there is no type, ans it's difficult to know the visibility and/or scope of a variable because of globals.

So for example, if we have a local variable in Lua defined like this.
local var

The hover will display "local var" as well.

So for me, this is not that interesting, until we have more information to put in the tooltip.
