Constructor Detail

GridLayoutDirector

public GridLayoutDirector()

Create a GridLayoutDirector with 0 horizontal gap and 0 vertical gap.

GridLayoutDirector

public GridLayoutDirector(double hgap,
                          double vgap)

Create a GridLayoutDirector with the given horizontal gap and vertical gap.

Parameters:

hgap - the horizontal gap

vgap - the vertical gap

Method Detail

getHGap

public double getHGap()

getVGap

public double getVGap()

invalidateLayout

public void invalidateLayout(PlotEx plot)

Description copied from interface: LayoutDirector

Invalidates the layout, indicating that if the layout manager has cached information it should be discarded.

Specified by:

invalidateLayout in interface LayoutDirector

Overrides:

invalidateLayout in class SimpleLayoutDirector

Parameters:

plot - the plot has been invalidate.

layout

public void layout(PlotEx plot)

Description copied from interface: LayoutDirector

Layout the plot. Normally the plot contents size is calculated by subtracting margin from plot size. If the plot has contents size constraint, the plot size is calculated by adding margin to plot content size.

Specified by:

layout in interface LayoutDirector

Overrides:

layout in class SimpleLayoutDirector

getPreferredContentSize

public java.awt.geom.Dimension2D getPreferredContentSize(PlotEx plot)

Description copied from class: SimpleLayoutDirector

Calculate the preferred content size of the given plot. The default implementation returns the plot.getPreferredContentSize(), which can be override by subclass to consider nested subplots. The returned size may be null if there is no enough information to derive a value.

Specified by:

getPreferredContentSize in interface LayoutDirector

Overrides:

getPreferredContentSize in class SimpleLayoutDirector

Returns:

the preferred content size
