Ok after loosing hairs with openfl or lime api and being unsuccesfull.
Here is a pure html5 workaround (for some that would stumble upon this post)
// some were in your state initialisation
var myInput = new FlxUIInputText();
#if js
//import js.Browser;
//import js.html.Clipboard;
//import js.html.ClipboardEvent;
Browser.document.addEventListener("copy", onCopy);
Browser.document.addEventListener("paste", onPaste);
#elseif flash
//Use Clipboard.generalClipboard
#end
add( myInput );
then the listeners
function onPaste(e: ClipboardEvent):Void
{
myInput.text = e.clipboardData.getData("text/plain");
}
function onCopy(e: ClipboardEvent):Void
{
Browser.navigator.clipboard.writeText(myInput.text);
}
