The Forms 4.5 "Drag and Drop" PL/SQL library is a trick. Forms 4.5 does not currently provide generic support for GUI Drag and Drop, in the same way as it does, for example for GUI Pop Lists.

The "demo" that Oracle gives reads the coordinates of the mouse, and compares that to a hardcoded list of the coordinates of the target objects, and then executes the relevant logic.

If you look carefully, you will see that Oracle does not actually claim support for real Drag and Drop in developed applications. I think that they included the demo for the purposes of helping their pre-sales effort. I would guess that there will be real support in Forms 5. Received on Mon May 06 1996 - 00:00:00 CEST
