How to access array controls by keyboard?

[Gerd W.]

It's possible to switch through different controls on a
frontpanel by using the TAB key. Is it also possible to access
the index or value of an array control by keyboard?

Best regards,

Hi Gerd,

you have to use the property IndexVals to set the index of element displayed in the top left corner of the array.
I attach a simple example with a 1D array and 2 up-down buttons.

Good luck,

Alberto

Hello Alberto,

the problem is somewhat different:
You can jump with the TAB key from one control to the next. If the control is a single element (like all the
numbers, booleans or strings) you can immediately change their value. If the control is an array, you cannot change the value nor the index. You have to select one of them WITH the mouse, to select and change them. And that's the problem!
I can change all values on a front panel only using the keyboard, but when encountering an array I have to use the mouse...
No way out?

Hi again,

I modified my example.
First you have to set the focus on array elements (press F3), then you can use TAB and Shift+TAB to move focus on elements.
I know this not as straigth-forward as tabbing through digital controls, but it lets you modify array elements without using the mouse.

Good luck,

Alberto

Actually, you can do this with the keyboard too. When tabbing or
shift-tabbing through a panel, clusters, arrays, and other aggregations
of controls are themself selected. When they are selected, press
Ctl-Down Arrow to go into the cluster/array, then tab to move through
the elements. At any time, press Ctl-Up Arrow to leave it. The array
moves through each element, then to each index, then cycles back to the
elements.

Fine!
I did not know this trick, the easiest solution is often just around the corner!

Just to check on this issue:

  Has an easy solution been created for tabbing into and out of a cluster yet???

 I want to be able to tab from FP element 1 -> 2 -> 3 ( a cluster) ->  cluster element 1-> 2 ->3  -> FP elemnt 4 -> 5 etc all by pressing tab.

  I am using 8.2  (but could upgrade to 8.5 if need be)


Thanks,  Kevin

Hi Kevin,

You cannot still be able to achieve it due to the limitations in LV (8.5) itself.

See the attached screenshots.

You can navigate to the controls/indicators inside a Tab, but not a Cluster.
