Constructor Detail

BalloonResizeController

public BalloonResizeController(WorldWindow wwd,
                               Balloon balloon)

Create a resize controller.

Parameters:

wwd - WorldWindow to interact with.

balloon - Balloon to resize.

Method Detail

detach

public void detach()

Remove this controller as an event listener. The controller will not receive input events after this method is called.

getBounds

public Rectangle getBounds()

Gets the bounds of the Balloon being sized.

Returns:

Balloon bounds in AWT coordinates, or null if no bounds have been set.

getBounds

protected Rectangle getBounds(PickedObject pickedObject)

Get the balloon bounds from a SelectEvent.

Parameters:

pickedObject - Top picked object. The bounds are expected to be attached to the to PickedObject under AVKey.BOUNDS.

Returns:

Bounds or null if no bounds are found in the top PickedObject.

getMinimumSize

protected 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.

Overrides:

getMinimumSize in class AbstractResizeHotSpot

Returns:

Minimum frame size.

See Also:

getScreenPoint

protected Point getScreenPoint()

Get the screen point of the upper left corner of the frame.

Specified by:

getScreenPoint in class AbstractResizeHotSpot

Returns:

Screen point measured from upper left corner of the screen (AWT coordinates).

getSize

protected Dimension getSize()

Get the size of the frame.

Specified by:

getSize in class AbstractResizeHotSpot

Returns:

Frame size in pixels.

isResizing

public boolean isResizing()

Is the controller currently resizing a balloon?

Returns:

True if the controller is currently resizing the balloon.

mouseMoved

public void mouseMoved(MouseEvent e)

Description copied from class: AbstractResizeHotSpot

Update the resize cursor when the mouse moves.

Specified by:

mouseMoved in interface HotSpot

Specified by:

mouseMoved in interface MouseMotionListener

Overrides:

mouseMoved in class AbstractResizeHotSpot

Parameters:

e - Mouse event.

setBounds

public void setBounds(Rectangle bounds)

Specifies the bounds of the Balloon to be sized.

Parameters:

bounds - Balloon bounds, in AWT coordinates.

setScreenPoint

protected void setScreenPoint(Point newPoint)

Set the screen point of the upper left corner of the frame.

Specified by:

setScreenPoint in class AbstractResizeHotSpot

Parameters:

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

setSize

protected void setSize(Dimension newSize)

Set the size of the frame.

Specified by:

setSize in class AbstractResizeHotSpot

Parameters:

newSize - New frame size in pixels.

updateCursor

protected void updateCursor()

Update the World Window's cursor to the current resize cursor.
