Busy Wheel, Progress Bar, Splash Screen

[Jolt]

I spent some time trying to create the behavior and effect of a “busy wheel” with some added functionality for feedback and control. I think I finally achieve decent results and thought I should share with the community.

Special thanks goes to Elijah_K and Mark.Ridgley whose examples provided the key pieces to this work. Please see: https://decibel.ni.com/content/docs/DOC-17541 and https://decibel.ni.com/content/docs/DOC-1086

This example is really designed as a “busy wheel” but the underlying functions and structure should be well suited to things like a progress bar or splash screen.

Some key features are transparent windows and asynchronous reentrant operation. “Wheelie” instances launch on top of everything and communicate using simple queues.

FYI: this will only work on Windows systems and cannot be used or saved in LV versions before 2012 (at least not without significant re-work).

Please feel free to leave suggestions in the comments section!

Cheers,
