This DHTML & Drag&Drop Library adds Drag&Drop functionality
|
|
to the following types of html-elements:
|
|
- images, even if not positioned via layers,
|
|
nor via stylesheets or any other kind of "hard-coding"
|
|
- relatively and absolutely positioned layers (DIV elements).
|
|
Moreover, it provides extended DHTML abilities.

/* my_PickFunc IS AUTOMATICALLY CALLED WHEN AN ITEM STARTS TO BE DRAGGED.
|
|
The following objects/properties are accessible from here:
|
|
|
|
- dd.e: current mouse event
|
|
- dd.e.property: access to a property of the current mouse event.
|
|
Mostly requested properties:
|
|
- dd.e.x: document-related x co-ordinate
|
|
- dd.e.y: document-related y co-ord
|
|
- dd.e.src: target of mouse event (not identical with the drag drop object itself).
|
|
- dd.e.button: currently pressed mouse button. Left button: dd.e.button <= 1
|
|
|
|
- dd.obj: reference to currently dragged item.
|
|
- dd.obj.property: access to any property of that item.
|
|
- dd.obj.method(): for example dd.obj.resizeTo() or dd.obj.swapImage() .
|
|
Mostly requested properties:
|
|
- dd.obj.name: image name or layer ID passed to SET_DHTML();
|
|
- dd.obj.x and dd.obj.y: co-ordinates;
|
|
- dd.obj.w and dd.obj.h: size;
|
|
- dd.obj.is_dragged: 1 while item is dragged, else 0;
|
|
- dd.obj.is_resized: 1 while item is resized, i.e. if <ctrl> or <shift> is pressed, else 0
