Textfield in cp5

Fem

How do I limit the amount of characters a user may press within a TextField?

Here is the API. Well organized but wished it explained the methods more in depth.

GoToLoop

Perhaps? http://www.sojamo.com/libraries/controlP5/reference/controlP5/Textfield.html#setWidth(int)

Fem

Gives an array out of bounds error

Fem

The setWidth() method just allows the bar to be wider. It has nothing to do with the character limit.!

GoToLoop

Maybe use a more detailed overload version for addTextField()? :-??

GoToLoop

Sorry, dunno either! b-(

Fem

It probably is not implemented.

GoToLoop

We can still throw away the exceeding characters via substring():

Fem

Good idea but how would you determine if the box currently has 3 chars so once it hits 4 chars it substrings it back to 3.

GoToLoop

Use length() in order to get String's size:
