Problem with button

[andersonfseabra3]

I have a registration screen that has the button to register in blue color, if something wrong happens in the registry (like email invalid) a popup appears and after the error message the boot registers with another color (pink) As if they’ve been holding it all the time. How do I solve this?

Try changing onPress in your widget.newButton to onRelease.  onPress will call the listener as soon as the user touches the button whereas the onRelease will call the listener immediately after the user takes their finger off the screen.

It was a good tip but when I changed, I do not know what happens to the pop ups I have that sends a message to the user that something is wrong, did not appear any more and when I came back to the onPress it worked (the With the same problem in the button)

That is likely because the onRelease only has an “ended” phase. Check out https://docs.coronalabs.com/api/library/widget/newButton.html#syntax

you can take out the check for event.phase so it would look something like this. hopefully that helps!

function salvarUsuario(event) local email = TxtEmail.text if ( email:match("[A-Za-z0-9%.%%%+%-]+@[A-Za-z0-9%.%%%+%-]+%.%w%w%w?%w?") ) then if TxtNome.text ~= "" and TxtSenha.text ~= "" then web:RegisterUserWS(TxtNome.text, TxtEmail.text, TxtSenha.text) else alert = native.showAlert("não foi possivel Cadastrar","preencha todos os campos", {"ok"} ) end else alert = native.showAlert("não foi possivel Cadastrar","email invalido", {"ok"} ) end end

Friend, in your first post I did as you said but I did not realize that I would have to change the event.phase from began to ended. With the link that you passed me I stopped to read the documentation and realized this carelessness of mine and I tested the ended and worked perfectly. thank you
