tooltips for block diagram code

[danbrown]

I'm a great advocate of commenting code, but with the graphical nature of Labview, you need space on your block diagram to add in a post-it giving your comments. That's great if your block diagram is nice and spread out, but (perhaps due to poor planning/programming) i'm often finding myself getting limited on space. Adding comment labels all over the place takes up even more space and results in the whole block diagram exploding to an often impractical size.

Wouldn't it be nice to be able to do an Excel-type tool-tip, where comments will be hidden until hovered over with the mouse?

Instead:

So many times this has been suggested.  Here's a few

I see I'm not the only one! Everyone using different tags & wording so I didn't come across them while checking to see if it had come up before. I like the result of using subvi's like here; I added a property node on the block diagram linked to the vi's description. That way all you have to do is open, type, hit run and save. Of course, the downside is you have to save a separate vi for every comment. 😕

The string constant with the comment saved in the constant description is easier to implement, but the result is a little less polished. Ho hum, maybe NI will implement an integrated version.

A Description and Tip... option is available in the context menu for most (if not all?) BD objects, but for some the Tip part is grayed out, and common for all unfortunately is that filling out Tip doesn't enable any tooltip anyway

Maybe that feature could just be turned on, it seems most of the code is already in place?

Use of the 2012 string constant editor would seem to do just about the same thing.
