Unfortunately the double click idea doesn't work well, because there is no consisten behaviour - you cannot rename complex watches with double click, only simple ones. Adding this feature is not a good idea.
The truncation of the tooltip is applied in rev 11122. Thanks for this contribution.

Correction of double clic (maintain expansion of item with children, and inactive on special items)

Ah ok for double click. I didn't see this kind of behaviour but I use CDB debugger only.
Your patch disables double-click renaming for watches with children, so you cannot see this effect.
If you're using cdb can you try this patch: https://sourceforge.net/p/codeblocks/tickets/269/ and report in the ticket if the patch is good?
