How do I know when a user drags a document to my app's icon?

[TiggerDad]

I'm on a Mac. When a user wants to open a file in my app, they usually open my app and use the "Open" menu item. So I can then use QFileDialog::getOpenFileName() to get the file's path, and I can open the file.

But sometimes they just go to the Finder and drag the file's icon on to my app's icon.

How do I get notified when that happens? And how do I know what the file is? Is there a signal somewhere I need to listen to?

Hi and welcome to devnet,

I think you are looking for QFileOpenEvent.

@SGaist yes, that’s exactly the thing I was looking for.

Many thanks. :-)
