webView(_:dragDestinationActionMaskFor:)
Returns a mask indicating which drag operations are allowed by the sender.
Declaration
optional func webView(_ webView: WebView!, dragDestinationActionMaskFor draggingInfo: (any NSDraggingInfo)!) -> IntParameters
- webView:
The web view that sent the message.
- draggingInfo:
The information object for the dragging operation.
Return Value
A mask that indicates which drag operations are allowed when content is dragged over the sending web view. (Note that the return value changed from an unsigned int to an NSUInteger in OS X v10.5.) See WebDragDestinationAction for a list of return values.
Discussion
This method can be invoked multiple times while content is dragged over the sending web view. When the content is dropped, the web view sends a notification (webView(_:willPerform:for:)) to the receiver.
If you do not implement this method, it returns any by default.
