Numeric Control Disable

[resrchengee]

Hi, I have a numeric control. I want to disable the option of having the user enter a number and hit enter. I only want them to be able to use the up and down arrows to change the control. Is this possible and how do i implement this? Thanks!

Select a "flat box" from decorations->Flat box, resize/move it to exactly cover the Numeric control user entry field and paint it transparent . Group it the flat box & Numeric control

See attached example.

-Kumar.B

Or catch all key events, and disgard them.

I like Kumar B's advice, but you should save it as a typedef.

You actually running the program or just put it on your front panel and clicked on it??? You can type on it if the program isn't running....you can't when it is running...

Wait...I posted the wrong one 😛

EDIT: Actually I didn't post the wrong one...When you save this make sure you save it disk then place the control on the front panel....I added it the block diagram via drag/drop, but came in as a constant (which I converted to a control), and it didn't work right....So save it, then add the control to the front panel via the controls pallete.

Be careful though. Using this method, you can still tab to the control to
give it key focus. You might not want to disable tabbing for the control,
because tabbing is sometimes very convenient.
