      com.mxgraph.layout.mxPartitionLayout

All Implemented Interfaces:

mxIGraphLayout

public class mxPartitionLayout
extends mxGraphLayout

Field Summary

protected int	border Integer that specifies the absolute inset in pixels for the parent that contains the children.
protected boolean	horizontal Boolean indicating the direction in which the space is partitioned.
protected boolean	resizeVertices Boolean that specifies if vertices should be resized.
protected int	spacing Integer that specifies the absolute spacing in pixels between the children.

Fields inherited from class com.mxgraph.layout.mxGraphLayout

graph, parent, useBoundingBox

Constructor Summary

mxPartitionLayout(mxGraph graph)
Constructs a new stack layout layout for the specified graph, spacing, orientation and offset.

mxPartitionLayout(mxGraph graph, boolean horizontal)
Constructs a new stack layout layout for the specified graph, spacing, orientation and offset.

mxPartitionLayout(mxGraph graph, boolean horizontal, int spacing)
Constructs a new stack layout layout for the specified graph, spacing, orientation and offset.

mxPartitionLayout(mxGraph graph, boolean horizontal, int spacing, int border)
Constructs a new stack layout layout for the specified graph, spacing, orientation and offset.

Method Summary

void	execute(Object parent) Executes the layout for the children of the specified parent.
mxRectangle	getContainerSize() Hook for subclassers to return the container size.
void	moveCell(Object cell, double x, double y) Notified when a cell is being moved in a parent that has automatic layout to update the cell state (eg. index) so that the outcome of the layout will position the vertex as close to the point (x, y) as possible.

moveCell

public void moveCell(Object cell,
                     double x,
                     double y)

Description copied from interface: mxIGraphLayout

Notified when a cell is being moved in a parent that has automatic layout to update the cell state (eg. index) so that the outcome of the layout will position the vertex as close to the point (x, y) as possible.

Specified by:

moveCell in interface mxIGraphLayout

Overrides:

moveCell in class mxGraphLayout

Parameters:

cell - Cell which is being moved.

x - X-coordinate of the new cell location.

y - Y-coordinate of the new cell location.

getContainerSize

public mxRectangle getContainerSize()

Hook for subclassers to return the container size.

execute

public void execute(Object parent)

Description copied from interface: mxIGraphLayout

Executes the layout for the children of the specified parent.

Specified by:

execute in interface mxIGraphLayout

Overrides:

execute in class mxGraphLayout

Parameters:

parent - Parent cell that contains the children to be layed out.
