B4J Question How do you trap the Escape key, ascii 27?

[B4JExplorer]

Hi,

I'm able to trap ordinary keys inside the TextChanged event. And the Enter key, inside the Action event.

But I'm not able to sense when the Escape key is pressed? Is there a specific event that automatically receives the escape key?

The Escape key won't change the text (in the text changed event). Try using the keypressed or keyreleased event instead (example here https://www.b4x.com/android/forum/t...row-keypress-in-a-text-box.76960/#post-487613)

Steve,

Thanks, I already had a keypress event defined, but the Esc key never triggered it. But I just found out the reason - in the AddEventHandler, the event name was spelled wrong; it was cloned from another project, and another event altogether.

Everything's good now, except for a question about programmatically cloning labels (another thread), thanks.

Can you post a link to the thread? I can't find it

It wasn't written yet. It's on the forum, now.
