Field Detail

offsetPoints

protected java.util.Hashtable<GrabPoint,OffsetGrabPoint.Offset> offsetPoints

The list of GrabPoints to move when this point moves.

overflowLock

protected boolean overflowLock

Flag used as a lock to prevent StackOverflowErrors, in case this OffetGrabPoint is unwittingly a child of itself.

Constructor Detail

OffsetGrabPoint

public OffsetGrabPoint(int x,
                       int y)

Create the OffsetGrabPoint at a certain window location.

Parameters:

x - horizontal pixel location from left side of window.

y - vertical pixel location from top side of window.

OffsetGrabPoint

public OffsetGrabPoint(int x,
                       int y,
                       int radius)

Create the OffsetGrabPoint at a certain window location.

Parameters:

x - horizontal pixel location from left side of window.

y - vertical pixel location from top side of window.

radius - the pixel radius of the point.

Method Detail

addGrabPoint

public GrabPoint addGrabPoint(GrabPoint gp)

Add a GrabPoint to the internal list.

removeGrabPoint

public GrabPoint removeGrabPoint(GrabPoint rgp)

Remove a GrabPoint to the internal list.

set

public void set(int x,
                int y)

Called when the position of the OffsetGrabPoint has moved. Does not adjust the offsets.

Overrides:

set in class OMPoint

setX

public void setX(int x)

Called when the X position of the OffsetGrabPoint has moved. Does not adjust the offsets.

Overrides:

setX in class OMPoint

setY

public void setY(int y)

Called when the Y position of the OffsetGrabPoint has moved. Does not adjust the offsets.

Overrides:

setY in class OMPoint

set

public void set()

Called when the other grab points may have moved, and the offset distances should be changed internally for the Offset objects.

moveOffsets

public void moveOffsets()

Go through all the Offset elements and changes their position on the map. Should be called when the OffsetGrabPoint has been moved and you want to move all the GrabPoints in its list.

updateOffsets

public void updateOffsets()

Go through all the Offset elements and update the relative position to this grab point. Should be called when you set the position of the OffsetGrabPoint and you want to set the offset distances of all the GrabPoints in the internal list.

clear

public void clear()

finalize

protected void finalize()

Overrides:

finalize in class java.lang.Object
