Hello, I finally make some input field to insert my data but I need my text inside input field shows the only capital letter. No matter I input the text with a capital letter or not.

Example: If I want to type text “hi” or “HI”
I want to show like this.

But now my program still show like this if I type text “hi”

-a- there is a event ENTERED
that would be after the [enter]
there you can call your own “text mod method”
-b- there is a function
https://processing.org/reference/String_toUpperCase_.html
you can use for this.

What is wrong with the Shift or Caps Lock key?
