Using Enter key from numeric keypad to enter and switch to next element in an array control

[KoosKoets]

Hello all,

I have a question regarding a simple but annoying problem, of which I did not found a solution yet.

I have written an application in which I have to enter data manually in a numeric array control.
If I want to enter the value and go to the next element in the array control, i am forced to use the Tab key on my keyboard, or risk RSI using the mouse.

How can I assign the Enter key of the numeric keypad section of my keyboard to to the same as the Tab key?

Kind regards,

Raymond

Your mean is how to escape use tab control to input array value? If so, you can use Event Structure achive this result,(Value change)

Hi Raymond,

IMHO tab-key is nice for this purpose... (left hand: tab, right hand: numpad )

As mentioned before you can use a value-changed event for this.
You can also filter out keypress-events for the array control using "KeyDown?" filter event: just go to next array element when numpad-enter is pressed...

To add to the previous answers... In the event structure, use the key focus
property to give the desired control the new key focus.

My prefered method is also using the Key Down? event, but with a small twist - the right terminals allow you to change the key that was clicked. This way, you can replace the Enter with a tab (ASCII 9). It just requires a case structure to only do this when you press Enter.

[Wiebe@CARYA]

That is indeed easier, because you don't have to deal with the ordering of
the controls yourself, you simple use LabVIEW's order.

One note to make here is that you can't use the Array -> Key Down? Event. This will not handle events that are fired on the array element only on the array control (with other words the digital index and scroll bars). Inorder to get the Key Down? event for the array elements you need to create a static reference for this element and use this to register a dynamic Key Down? event. This event will fire when you press a key when editing any element in the array.

Now you can filter the Enter to a Tab and make the focus jump to the next array element while editing. Attached a small example that demonstrates this.

Thanks

Thanks. I didn't have relevant code in front of me, so I forgot to mention that.

Can you convert the example in a image or can you convert in to 8.2.1 version?.
