KeyFocus Change Event

[paul_cardinale]

I wanted to trap changes in key focus, but there's no built-in event for it.  I couldn't find anything online that someone had already built, so I invented my own.  It's a bit messy under the hood, but fairly clean at the top level.

Labview 2016

Nothing happened for me when I clicked either the Boolean button or the Stop button (the latter I understand ...).

I understand the logic of putting the code in a library (an .lvlib file).  But what is the reason/are the advantages of using a .llb to further "bundle" these routines?  [I partly answered my own question by using LabVIEW Help, including the Saving VIs section, but I'm still a bit unsure I completely "get it" ...]

Clicking on the Boolean doesn't give it  key focus.

I use .llbs as a convenient way to package a set of related VIs.

Here's an improved version.

I guess you all kudoed this (mine) idea?

Wow, a 5-year-old, 130 (now 131) Kudo'ed Idea still hanging in there.  Go, GerdW!

On that old post, someone wanted the event data to include info about which control previously had focus.

This raises the question: The 'previous control' on the current VI, or the 'previous control' on any VI?

The first would be fairly easy to add.  The second, I haven't figured out a way to do that.

After many machinations, I came up with a version that works with multiple simultaneous VIs and also with multi-pane VIs.
