Does Qt support the Clipboard API? How do I use it?

[Anon123]

[EDIT: I'm using Qt 6.2.4]

I'm trying to use Clipboard.write() to push some data from my application to the user's clipboard. I have QWebEngineSettings::JavascriptCanAccessClipboard and even QWebEngineSettings::JavascriptCanPaste set to true.

When I try to call navigator.clipboard.write() from JS loaded on the page, it throws an exception "Write permission denied".

If I check with navigator.permissions.query() for clipboard-write, I get { state: "denied" }.

How do I set that permission? MDN documentation linked above indicates it should be set automatically, although I don't know if "browser tabs" are a salient concept within the context of Qt. I haven't been able to find any additional knobs to turn by browsing the Qt documentation.

Thanks in advance.
