@hrzjanati there’s an example in the comment:
Text("Hello")
.onDoubleClick { print("Double click detected") }
Can we enable VO + Space to mimic double click action when VO enabled ?
@hrzjanati there’s an example in the comment:
Text("Hello") .onDoubleClick { print("Double click detected") }
Thank's
This works, thanks! I spent days on this.

Glad to help!
Joel, this was a super-handy piece of code, thank you! May I ask what licensing you're applying to it?

@erichfin None, feel free to copy/modify/whatever. (I hope this comment can be legally binding 😀)
Ha, I'll take it! Thank you for the prompt response, and, again, for sharing the code Joel!
