issues in latest Google Chrome 117

[zhil]

After recent Google Chrome update I noticed, that react-signature-canvas is not working correctly any more.

Line is showed as dotted line and auto-removed.

Here is online sandbox

Not working in Google Chrome 117.0.5938.132 on Ubuntu

Works just fine in Firefox on the same PC

I'm not sure that there's anything we can really do about a Chrome regression, especially in this tiny wrapper

Sorry, I didnt realize, that this library is a wrapper.

I reported issue here
szimek/signature_pad#734

@agilgur5 native library author proposed solution, but I cant use it

szimek/signature_pad#734

You can opt in with something like this:

signaturePad.addEventListener("afterUpdateStroke", () => {
  window.resize();
});

I cant find any way to add event listener. I tried to use code like

sigPadRef.current._sigPad.addEventListener("afterUpdateStroke", () => {
            console.log('ACA-512 patch');
            window.resize();
        });

<SignatureCanvas ref={sigPadRef} ..... />

but its not working.

Also I cant find any props like OnAfterUpdateStroke etc. :(

Yes that's part of the signature_pad v4 API. react-signature-canvas is still on v2 as v4 had many breaking changes that no contributor has attempted to address yet. See also #68

You can use the onEnd prop/callback which is roughly equivalent to v4's afterUpdateStroke.
