addMergedDropTarget
void addMergedDropTarget(Control control, int ops, Transfer[] transfers, DropTargetListener listener)
Causes a drop target to be added to the given control that respects the existing site's drop behaviour in addition to the behaviour being specified for the given control.If a transfer type specified for the control matches one used by the site then the control's listener is called (the client is overriding the existing site behaviour which will no longer work).
NOTE: Site authors must use this method to add drop behaviour; directly adding drop targets using SWT onto a site will cause the standard site behaviour (i.e. dragging files / markers into the EditorSite...) to not work when that editor is active.
Note that this method may be used more than once should the part author wish to register different drop targets for internal controls (i.e. to support internal DnD).
- Parameters:
control
- The control to add the drop behaviour toops
- The Drop operations used by this targettransfers
- The TransferTypes used by this targetlistener
- The listener controlling the target's behaviour
