If we have a drag&drop target component, and a user drags&drops a non-supported file over the component, will we get any kind of feedback/callback that this is happening? Or will it simply refuse to allow dropping, with no way to tell the user why it’s not allowed in this case? We’re being asked to provide feedback that the given object type being dragged/dropped is not allowed (e.g., it’s not an audio or midi file), and I need to know if we can detect that or not in a way that allows us to notify the user, such as by showing text on the target component.
Ah, that’s what fileDragEnter() allows, according to its header file comments. Perfect!
Use this callback as a trigger to make your component repaint itself to give the
user feedback about whether the files can be dropped here or not.```
