for the final version and project example
There ´ll be no more versions. As the library is from 2015 i know i do not have the source anymore (HDD crash in 2016).
Do not expect any new here. Use the library in #1. Example is in #1 too.

If it´s fit your needs; great. If not; search for alternatives.

I encourage you to do it. I can't right now, maybe next week. It is not complicated and you will open up new possibilities.

(in spain we say: 'el rascar es todo empezar' - scratching is all beginning)

doit:
- install eclipse
- do a simple change:
* in signPad.java added this code:



ba.raiseEvent(this, eventName + "_onclear");

B4X:
    @Override
      public void onClear() {
          BA.Log("onClear() evento rav");

          ba.raiseEvent(this, eventName + "_onclear");
          //mSaveButton.setEnabled(false);
          //mClearButton.setEnabled(false);
      }
    };


- install https://www.b4x.com/android/forum/t...-libraries-without-eclipse.29918/#post-173756
and compile

problems:
* b4DocLet are not in my computer (view previous thead)
* case sensitive : ba.raiseEvent(this, eventName + "_onClear"); (C in Clear must be minus!!)

And now, incluye in your B4A proyect the detect event:
B4X:
Sub SignaturePad_onSigned(sign As Object)
    If ValidarDniYNombre = False Then
   
        SignaturePad.clear
        SignaturePad.Tag = ""
        MsgboxAsync("Complete Nombre y apellidos,  y  DNI con 9 caracteres. No indique guiones","Faltan datos")
    Else
        SignaturePad.Tag = "Firmado"
    End If
   
End Sub


'this event are raised a lot of times.
Sub SignaturePad_onClear()
'    MsgboxAsync ("Borrado","Borrado")
End Sub

importan:
may be is better use:

now i have a problem with this library in my proyect:
error pasing librarie
com.github.gcacace.signaturepad.views
signaturepad.strokewidth alrady existe
and the version is 0.0 with the previous are 0.22
i think the problem is the commple method ( in previus version 5 year ago!!! i compile with javadoc ...)
i go to use the previous version in my proyect.

my be the correct implements are in official touchpad of DonManfred.

(at the risk of being annoying, but for leaving everything documented:)

You have to include com.github in the compiler that I mentioned, as I have seen in another thread.
This is:
-b4aignore: org,com.android,com.example,com.hoho,com.github

But anyway the XML has some different entries that makes my project fail to compile.


Attach images.
