All Implemented Interfaces:

AVList, SelectListener, HotSpot, java.awt.event.KeyListener, java.awt.event.MouseListener, java.awt.event.MouseMotionListener, java.awt.event.MouseWheelListener, java.util.EventListener

Direct Known Subclasses:

BalloonResizeController, FrameResizeControl
```
public abstract class AbstractResizeHotSpot
extends AbstractHotSpot
```
A HotSpot for resizing a frame or window. This class handles the resize input events, but does does not actually draw the resize controls. The HotSpot is defined by a direction, for example, AVKey.NORTH indicates that the HotSpot resizes the frame vertically from the north edge (the user clicks the top edge of the frame and drags vertically).
An instance of this class should be added to the picked object when the edge or corner of the frame is picked.
Subclasses must the implement {#getSize}, {#setSize}, {#getScreenPoint}, and {#setScreenPoint} to manipulate the frame that they want to resize.

```
  - drag
```
public void drag(java.awt.Point point)
```
  - endDrag
```
protected void endDrag()
```
    Called when a drag action ends. This implementation sets dragRefPoint to null.
  - getCursor
```
public java.awt.Cursor getCursor()
```
    Get a cursor for the type of resize that this hotspot handles.
    
    Specified by:
    
    getCursor in interface HotSpot
    
    Overrides:
    
    getCursor in class AbstractHotSpot
    
    Returns:
    
    New cursor.
  - getMinimumSize
```
protected java.awt.Dimension getMinimumSize()
```
    Get the minimum size of the frame. The user is not allowed to resize the frame to be smaller than this size. This implementation returns 0, 0.
    
    Returns:
    
    Minimum frame size.

                              int height)
```
    Is a frame size valid? This method is called before attempting to resize the frame. If this method returns false, the resize operation is not attempted. This implementation ensures that the proposed frame size is greater than or equal to the minimum frame size.
    
    Parameters:
    
    width - Frame width.
    
    height - Frame height.
    
    Returns:
    
    True if this frame size is valid.

  - mouseMoved
```
public void mouseMoved(java.awt.event.MouseEvent e)
```
    Update the resize cursor when the mouse moves.
    
    Specified by:
    
    mouseMoved in interface HotSpot
    
    Specified by:
    
    mouseMoved in interface java.awt.event.MouseMotionListener
    
    Overrides:
    
    mouseMoved in class AbstractHotSpot
    
    Parameters:
    
    e - Mouse event.
  - selected
```
public void selected(SelectEvent event)
```

```
    Called when this HotSpot is activated or deactivated. The HotSpot only receives input events when it is active. Overridden to reset state when the mouse leaves the resize area.
    
    Specified by:
    
    setActive in interface HotSpot
    
    Overrides:
    
    setActive in class AbstractHotSpot

```
    Set the resize direction based on which point on the frame was picked (if a point on the left of the frame is picked, the resize direction is west, if a point on the top edge is picked the resize direction is north, etc).
    
    Parameters:
    
    pickPoint - The point on the frame that was picked.
  - setScreenPoint
```
protected abstract void setScreenPoint(java.awt.Point newPoint)

    newPoint - New screen point measured from upper left corner of the screen (AWT coordinates).
  - setSize
```
