Method Detail

getGap

public int getGap()

Returns the number of pixels the figure's bounding rectangle is from the connection. Only used if getRelativePosition() returns something other than CENTER.

Since:

2.0

getReferencePoint

protected abstract Point getReferencePoint()

Returns a reference point used to calculate the location.

Since:

2.0

getNewBounds

protected Rectangle getNewBounds(Dimension size,
                                 Point center)

Recalculate the location of the figure according to its desired position relative to the center point.

Since:

2.0

getRelativePosition

public int getRelativePosition()

Returns the position of the figure with respect to the center point. May be CENTER, NORTH, SOUTH, EAST, WEST, NORTH_EAST, NORTH_WEST, SOUTH_EAST, or SOUTH_WEST.

Since:

relocate

public void relocate(IFigure target)

Description copied from interface: Locator

Relocates the given IFigure.

Specified by:

relocate in interface Locator

setGap

public void setGap(int i)

Sets the number of pixels the figure's bounding rectangle is from the connection. Only used if getRelativePosition() returns something other than CENTER.

Since:

2.0

setRelativePosition

public void setRelativePosition(int pos)

Sets the position of the figure with respect to the center point. May be CENTER, NORTH, SOUTH, EAST, WEST, NORTH_EAST, NORTH_WEST, SOUTH_EAST, or SOUTH_WEST.
