This component implements the following interfaces:
Constants
| PRInt32 | nsIDragService.DRAGDROP_ACTION_NONE | = 0 |
| PRInt32 | nsIDragService.DRAGDROP_ACTION_COPY | = 1 |
| PRInt32 | nsIDragService.DRAGDROP_ACTION_MOVE | = 2 |
| PRInt32 | nsIDragService.DRAGDROP_ACTION_LINK | = 4 |
Properties
PRBool nsIDragSession.canDrop
Set the current state of the drag, whether it can be dropped or not. usually the target "frame" sets this so the native system can render the correct feedback
PRUint32 nsIDragSession.dragAction
Sets the action (copy, move, link, et.c) for the current drag
readonly PRUint32 nsIDragSession.numDropItems
Get the number of items that were dropped
readonly nsIDOMDocument nsIDragSession.sourceDocument
The document where the drag was started, which will be null if the drag originated outside the application. Useful for determining if a drop originated in the same document.
readonly nsIDOMNode nsIDragSession.sourceNode
The dom node that was originally dragged to start the session, which will be null if the drag originated outside the application.
nsSize nsIDragSession.targetSize
Sets the current width and height of the drag target area. It will contain the current size of the Frame that the drag is currently in
