  • Method Details

    • isActive

      public boolean isActive()
      Specified by:
      isActive in interface Interactor

    • activate

      public boolean activate()
      Specified by:
      activate in interface Interactor

    • deactivate

      public void deactivate()
      Specified by:
      deactivate in interface Interactor

    • getCursor

      public Cursor getCursor()
      Specified by:
      getCursor in interface Interactor

    • mouseEntered

      public void mouseEntered(MouseEvent event)
      Invoked when the mouse enters a component.

      The default implementation does nothing.

      Specified by:
      mouseEntered in interface MouseListener
      Parameters:
      event - The mouse event.

    • mouseExited

      public void mouseExited(MouseEvent event)
      Invoked when the mouse exits a component.

      The default implementation does nothing.

      Specified by:
      mouseExited in interface MouseListener
      Parameters:
      event - The mouse event.

    • mousePressed

      public void mousePressed(MouseEvent event)
      Invoked when a mouse button has been pressed on a component.

      The default implementation does nothing.

      Specified by:
      mousePressed in interface MouseListener
      Parameters:
      event - The mouse event.

    • mouseReleased

      public void mouseReleased(MouseEvent event)
      Invoked when a mouse button has been released on a component.

      The default implementation does nothing.

      Specified by:
      mouseReleased in interface MouseListener
      Parameters:
      event - The mouse event.

    • mouseClicked

      public void mouseClicked(MouseEvent event)
      Invoked when the mouse button has been clicked (pressed and released) on a component.

      The default implementation does nothing.

      Specified by:
      mouseClicked in interface MouseListener
      Parameters:
      event - The mouse event.

    • mouseDragged

      public void mouseDragged(MouseEvent event)
      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.

      The default implementation does nothing.

      Specified by:
      mouseDragged in interface MouseMotionListener
      Parameters:
      event - The mouse event.

    • mouseMoved

      public void mouseMoved(MouseEvent event)
      Invoked when the mouse cursor has been moved onto a component but no buttons have been pushed.

      The default implementation does nothing.

      Specified by:
      mouseMoved in interface MouseMotionListener
      Parameters:
      event - The mouse event.

    • keyPressed

      public void keyPressed(KeyEvent event)
      Invoked when a key has been pressed. See the class description for KeyEvent for a definition of a key pressed event.

      The default implementation does nothing.

      Specified by:
      keyPressed in interface KeyListener
      Parameters:
      event - The key event.

    • keyReleased

      public void keyReleased(KeyEvent event)
      Invoked when a key has been released. See the class description for KeyEvent for a definition of a key released event.

      public void keyTyped(KeyEvent event)
      Invoked when a key has been typed. See the class description for KeyEvent for a definition of a key typed event.

      The default implementation calls cancelInteraction(java.awt.event.InputEvent) if the "ESC" key has been typed.

      Specified by:
      keyTyped in interface KeyListener
      Parameters:
