I just recently did this in my project.
In your example of a ChildComponent and ParentComponent you can have
<ChildComponent @click="$emit('myEvent', 1)" />
<ParentComponent @myEvent="eventHandler(2, ...arguments)" />
Then your eventHandler would look like this
function eventHandler(parentArgument, childArgument) { ... }
You can probably change the ordering as you wish but this worked for me. Also just a side note I believe it’s recommended to use kebab-case for the html elements.
