Dragging from a list field

[Eric Chatonet]

Hi Jacque,

Sorry, I'm coming a bit late...
I have done such a thing in a project where the user can drag and  
drop images, movies, sounds and texts from a palette that displays  
their images in order to build a multimedia document. So between two  
stacks.
I had a specific stack for this purpose displaying an image created  
on-the-fly by taking a snapshot.
This tiny stack was shown at mouseDown, covering exactly the actual  
image in the palette and then the user could drag it where he/she  
wanted.
A pending message told me where the mouseUp occurred and I acted  
accordingly.
I used this method since I wanted the stack to move smoothly to its  
starting position if it was not in a "right" place and this feature  
made the job much more tricky :-)
As far as I remember, a lot of code, some focus and cross-platform  
issues and so on, but a fine result :-)

Best Regards from Paris,

Eric Chatonet.

PS. If you are interested in more details, write me off list.
