I had thought that Director's large "cursors" were simply images that follow the mouse, something that could be done with a mouseMove handler in Rev, no?
This is *mostly* the case. Director has somewhat better support for actually replacing the hardware "cursor" than Rev does, but when it comes to cursors larger than the OS is intended to support, then it is the old "hide the cursor and move an image with the mouseLoc" just like pretty much everything else does.
I brought subject this up because I was running into problems when trying to use the drag event handlers (dragEnter, dragMove, etc.) when dragging and dropping within my own Revolution application.
When doing drag and drop within a field I've used the floating palette method that appears, follows the mouse and disappears when done.
When dragging from one field to another I wanted to use the dragEnter/dragLeave handlers to handle visual cues of fields that the user could drop data on. The problem is that you can't get a palette to follow the pointer between Revolution windows this way. Setting the cursor to the image you want to use would solve this problem but cursors are limited in size. So it seems that these handlers are best used when dealing with drag/drop between applications.
So to sum up, here is how I *think* this all works:
Drag and Drop within your own Application -
Set a custom cursor if it can fit within the cursor size constraints. Use a palette with an image that follows the pointer around with mouseMove when needed. Make palette transparent for extra fun. Visual feedback is handled with mouseEnter/mouseLeave and some sort of global or custom property that determines what type of data you are dragging.
Between applications - Use drag events. Set a custom cursor for visual feedback.
If anyone has any additional insight then please share. Perhaps this was obvious to others but I haven't worked with drag and drop before so it wasn't for me.
