Currently the submit event emitted by QForm does pass the event object to the handler but it's not defined in the types. As VeeValidate depends upon the submit event for it's handleSubmit slot prop, it throws type error as the event is undefined.

Hi,

Thanks for contributing!
This will go into Quasar v2.5.4.

It breaks the build, but will fix it in a subsequent commit.

Thanks, I'm sorry for the build failure. I'm not 100% acquainted with the type generation system of quasar. Will try to look into it.

No problem. Thanks for PRing!
