Method Detail

getButton

public int getButton()

Returns the mouse button that changed state.

getX

public float getX()

Returns the horizontal x position of the event relative to the source graphics node.

Returns:

x a float indicating horizontal position relative to the node

getY

public float getY()

Returns the vertical y position of the event relative to the source node.

Returns:

y a float indicating vertical position relative to the node

getClientX

public float getClientX()

Returns the horizontal x position of the event relative to the source graphics node.

Returns:

x a float indicating horizontal position relative to the node

getClientY

public float getClientY()

Returns the vertical y position of the event relative to the source node.

Returns:

y a float indicating vertical position relative to the node

getScreenX

public int getScreenX()

Returns the horizontal x position of the event relative to the screen.

Returns:

x a float indicating horizontal position relative to the screen

getScreenY

public int getScreenY()

Returns the vertical y position of the event relative to the screen.

Returns:

y a float indicating vertical position relative to the screen

getScreenPoint

public Point getScreenPoint()

Returns the (x, y) position of the event relative to the screen.

Returns:

a Point object containing the x and y coordinates

getClientPoint

public Point getClientPoint()
