Method Detail

addLayoutComponent

public void addLayoutComponent(Component component, Object constraints)
Adds the specified component to the layout, with the specified constraints object.

Parameters: component the component to add constraints the constraints to satisfy

getLayoutAlignmentX

public float getLayoutAlignmentX(Container target)
Returns the preferred X axis alignment for the specified target container. This value will range from 0 to 1 where 0 is alignment closest to the origin, 0.5 is centered, and 1 is aligned furthest from the origin.

Parameters: target the target container

Returns: the x-axis alignment preference

getLayoutAlignmentY

public float getLayoutAlignmentY(Container target)
Returns the preferred Y axis alignment for the specified target container. This value will range from 0 to 1 where 0 is alignment closest to the origin, 0.5 is centered, and 1 is aligned furthest from the origin.

Parameters: target the target container

Returns: the y-axis alignment preference

invalidateLayout

public void invalidateLayout(Container target)
Forces the layout manager to purge any cached information about the layout of the target container. This will force it to be recalculated.

Parameters: target the target container

maximumLayoutSize

public Dimension maximumLayoutSize(Container target)
