While drag-and-drop of an object (possibly from another window or application) is in progress, I'd like to provide some visual cues and control over the drop destination. In particular, I'd like to be able to scroll the drop target view in response to the scroll wheel event and also respond to some keys.
To my surprise, however, the scroll wheel events are not dispatched immediately, but accumulated until the drop is complete and then they burst out all at once. The keyboard events (except some modifier keys that can be indirectly tested via the NSDraggingInfo) are absorbed altogether and never reach the drop target. Is there any workaround for this? I assume that the system's drag-and-drop manager sets up its own run loop. I thought I could override -[NSApplication sendEvent:], but as the experiment has shown, it doesn't fix the problem. Can there be a more up-stream way to install kind of a hook to intercept the messages that I want? _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
