There is a video linked in that post that pretty simple shows the behaviour. It is quite nice to use.

Interesting idea, I've made a quick implementation of it just for fun. This might actually be usefull on touch screen GUIs, I need to explore that.

Nice! Now make it infinite pac-man style scrolling like in that video

Nice. Is an XControl in the works? You know, for science

@thols, it's doable, I may do it for further fun

@ShaunR, nah, just event structure and Input Device Control pallete. Attached the LV8.5 version if you want to take a look. Implementing it in XControl would be cumbersome as it needs to pool the mouse continously. (Plus I removed XControls entirely from my "technology toolbox" a long time ago, together with tons of problems they cause).

I usually """solve""" this kind of thing with placing a full-window transparent control over everything and showing it on mouse down and hiding on mouse up event. Fails miserably with multi-pane front panels and have to be extra careful for z-order.

Quick n dirty, the way I do LV.

I know what you mean. I have the same view about ActiveX and .NET. But XControls aren't as bad as those technologies and, although a lot of work to make them robust, they are worth it is some scenarios.
