Ctrl + mouse wheel: Scroll through array elements when hovered over

Status: New

This idea is currently in the LabVIEW NXG backlog. For LabVIEW 20xx, I'm moving the idea back to the 'New' status to be considered for a future LabVIEW 20xx release.

With a case structure I can place the mouse cursor over the structure and Ctrl + scroll wheel to cycle through the cases without it being active. If I try doing this on arrays it doesn't work.

 

For front panel arrays the numeric indicator must have focus for this to work. Doesn't work when the array data is selected. I understand that multidimensional arrays would be a problem, but for 1D arrays it would be nice if it cycled through the elements.

 

For array constant block diagram elements, no scroll action works regardless of what is active. Again it should allow the user to cycle through elements for 1D arrays simply by hovering over the item and Ctrl + scroll wheel.

I'm not sure what you're talking about. As far as I can tell, Ctrl+Scroll does nothing for arrays. I can use just the scroll wheel to scroll arrays both on the FP and the BD, as long as the cursor is on top of them, no focus required.

 

As said in the other idea, it was implemented in LV 2013. I'm not sure how your idea is different (other than that you seem to want the Ctrl modifier for some reason).

And the scroll bar has to be visible, which I have learned is a good thing to have anyways.

Sorry for the confusion.

 

When you say: "I can use just the scroll wheel to scroll arrays both on the FP and the BD, as long as the cursor is on top of them, no focus required."

Do you mean it increments/decrements the index value as you scroll (thats what I'm after)?

 

Just like the effect of hovering over a case structure and Ctrl + scroll wheel cycles through all of the cases. It works well for this so why not add it to arrays was my thinking.

 

Not the scroll bar.

 

On my third paragraph of the original idea I should have put: "no Ctrl + scroll action works, regardless of what is active"

 

E.g. Hover over 1D array on BD or FP

Ctrl + scroll up: index value increments/shows next element.

Ctrl + scroll down: index value decrements/shows previous element.

Yes, the index values will increment/decrement as you scroll.  You do have to have the scroll bar visible.  But then you just put the cursor over the array (does not seem to work with the index display) and scroll.

For 3D or more the scroll bars don't work. Many times we don't want to have the scroll bars on. Kudos!

I see what you mean about the scroll bar now. It does work, but it would be more intuitive (in my opinion) if it carried over the case structure implementation.

 

Heres an animation for clarity:

(wish I could modify the original idea to add the animation in...)

The case structure scrolls in the opposite direction. Likewise, I'd like to see scrolling down used to increment the index.
