Change the Label/Tooltip for MenuItem and ToolItem depended on Selection [message #1693355]

Hi everybody!

I have just been asked if it would be possible to change to label (or tooltip) of a MenuItem (or ToolItem) dependend on the current selection. These items could be anywhere including the main menu and/or context menus.

The thinking is to define the label like this:

"lorem ipsum ${<default>;MyItem.myAttribute} dolor"

and then recalculate the the text everytime the active selection changes. The replacement would be calculated using the bean pattern on the selection. If the selection is empty, does not fit the type, or contains multiple elements, the <default> would be used.

Any ideas on how to go about doing this? Would the new message extension be of any help implementing this?

Is there any interest in the community for a feature like this, as we might be able to put some time into this?

Smile
Christoph

It should not be too hard to implement this - generally you need to this
in our BaseRenderer#handleAttributeChange where you'll have to look at
the value returned from l.getLocalizedTooltip() - I think you need to
use a RAT for tracking value changes.

Generally this sounds like an cool feature and I'd happily merge this
into the codebase. I guess first step is to file a bugzilla and we go on
there with the discussion.
