      Constructs a new instance of MouseInputHandler.
      Parameters:
      source - a source component
      destination - a destination component

  • Method Details

    • mouseClicked

      public void mouseClicked(MouseEvent e)
      Description copied from interface: MouseListener
      Invoked when the mouse button has been clicked (pressed and released) on a component.
      Specified by:
      mouseClicked in interface MouseListener
      Parameters:
      e - the event to be processed

    • mousePressed

      public void mousePressed(MouseEvent e)
      Description copied from interface: MouseListener
      Invoked when a mouse button has been pressed on a component.
      Specified by:
      mousePressed in interface MouseListener
      Parameters:
      e - the event to be processed

    • mouseReleased

      public void mouseReleased(MouseEvent e)
      Description copied from interface: MouseListener
      Invoked when a mouse button has been released on a component.
      Specified by:
      mouseReleased in interface MouseListener
      Parameters:
      e - the event to be processed

    • mouseEntered

      public void mouseEntered(MouseEvent e)
      Description copied from interface: MouseListener
      Invoked when the mouse enters a component.
      Specified by:
      mouseEntered in interface MouseListener
      Parameters:
      e - the event to be processed

    • mouseExited

      public void mouseExited(MouseEvent e)
      Description copied from interface: MouseListener
      Invoked when the mouse exits a component.
      Specified by:

    • mouseDragged

      public void mouseDragged(MouseEvent e)
      Description copied from interface: MouseMotionListener
      Invoked when a mouse button is pressed on a component and then dragged. MOUSE_DRAGGED events will continue to be delivered to the component where the drag originated until the mouse button is released (regardless of whether the mouse position is within the bounds of the component).

      Due to platform-dependent Drag&Drop implementations, MOUSE_DRAGGED events may not be delivered during a native Drag&Drop operation.

      Specified by:
      mouseDragged in interface MouseMotionListener
      Parameters:
      e - the event to be processed

    • mouseMoved

      public void mouseMoved(MouseEvent e)
      Description copied from interface: MouseMotionListener
      Invoked when the mouse cursor has been moved onto a component but no buttons have been pushed.
      Specified by:
      mouseMoved in interface MouseMotionListener
      Parameters:
      e - the event to be processed

    • removeFromSource

      protected void removeFromSource()
      Removes an event from the source.
