Method Detail

isHorizontal

public boolean isHorizontal()

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.
