SWT 拖拽

两种方式：

 

1. 

transfer = LocalSelectionTransfer.getTransfer();
DragSource ds = new DragSource(table, DND.DROP_MOVE);
ds.setTransfer(new Transfer[] { transfer });
ds.addDragListener(new DragSourceAdapter() {
	public void dragSetData(DragSourceEvent event) {
		transfer.setSelection(tableViewer.getSelection());
	}
});

DropTarget table_1DropTarget = new DropTarget(table_1,DND.DROP_MOVE);
table_1DropTarget.setTransfer(new Transfer[] { transfer });
table_1DropTarget.addDropListener(new DropTargetAdapter() {
	public void drop(DropTargetEvent event) {
		StructuredSelection s = (StructuredSelection) event.data;
	}
});

 

2.

 

tableViewer.addDragSupport(DND.DROP_MOVE, new Transfer[]{transfer}, new DragSourceAdapter(){
	public void dragSetData(DragSourceEvent event) {
		...
	}
});

 

 

tableViewer_1.addDropSupport(DND.DROP_MOVE,new Transfer[]{transfer}, new DropTargetAdapter(){
	public void drop(DropTargetEvent event) {
		...
	}
});

 

这里的Adapter和Listener区别在于，Listener要实现所有的函数，Adapter可以只选择需要的
