Drag and Drop components from one frame to another frame

Drag and Drop components from one frame to another frame


Java code given below shows that how to drag and drop component (drop down list, text area, check box, radio button etc.) from one frame to another frame. In this code we have used following interfaces.....

1: DragGestureListener : This interface is invoked when an object of that class or its subclass detects a drag initiating gesture.

2: DragSourceListener : This interface provides event notification to the application for DragSource events.

3: DropTargetListener : This interface is used by the DropTarget class to provide notification of DnD operations.

4: Transferable : This interface provides data for a transfer operation.

Compile this java code with javac command  from command prompt then run. When run this code this shows two separate frames.......

 One frame has five component, user can drag and drop component from one to another frame.
