Method Detail

paintComponent

protected void paintComponent(java.awt.Graphics graphics)

Overrides:

paintComponent in class javax.swing.JComponent

paintCore

protected void paintCore(java.awt.Graphics2D g,
                         int x,
                         int y,
                         int w,
                         int h)

print

public int print(java.awt.Graphics graphics,
                 java.awt.print.PageFormat pageFormat,
                 int pageIndex)
          throws java.awt.print.PrinterException

Specified by:

print in interface java.awt.print.Printable

findDraggable

public Draggable findDraggable(int x,
                               int y)

Description copied from interface: DragCapable

Given the coordinates of a mouse click, return the corresponding draggable widget.

Specified by:

findDraggable in interface DragCapable

Following copied from interface: com.dixshtix.awt.DragCapable

Parameters:

x - The x-coordinate of the mouse down event.

y - The y-coordinate of the mouse down event.

Returns:

A matching Draggable or null if no shape matches.

pinPoint

public java.awt.geom.Point2D pinPoint(Draggable ignored,
                                      java.awt.geom.Point2D original,
                                      int deltaX,
                                      int deltaY)

Description copied from interface: DragCapable

Given the original position of the current draggable, and the requested offset, compute the constrained current position.

Specified by:

pinPoint in interface DragCapable

Following copied from interface: com.dixshtix.awt.DragCapable

Parameters:

d - The Draggable shape which is being dragged.

original - The original position of the shape.

delta_x - The horizontal offset of the ongoing drag.

delta_y - The vertical offset of the ongoing drag.

Returns:

The logical position of the currently dragged shape which might be thought of as the constrained sum of the original and offset.

dragNotify

public void dragNotify(Draggable d,
                       java.awt.geom.Point2D oldPos,
                       java.awt.geom.Point2D newPos)

Description copied from interface: DragCapable

Message sent upon the completion of a drag gesture. The exact processing of this message is highly application-dependent.

Specified by:

dragNotify in interface DragCapable

Following copied from interface: com.dixshtix.awt.DragCapable

Parameters:

d - The Draggable shape which has been dragged.

oldPos - The location of the draggable at the beginning of the drag gesture.

newPos - The location, returned by DragCapable.pinPoint(com.dixshtix.awt.Draggable, java.awt.geom.Point2D, int, int), of the draggable at the end of the drag gesture.

addDraggable

public void addDraggable(Draggable d)

main

public static void main(java.lang.String[] args)
