Specified by:

minimumLayoutSize in interface java.awt.LayoutManager

Parameters:

parent - the component to be laid out

See Also:

preferredLayoutSize(java.awt.Container)

addLayoutComponent

public void addLayoutComponent(java.awt.Component comp,
                               java.lang.Object constraints)

Adds the specified component to the layout, using the specified constraint object.

getLayoutAlignmentX in interface java.awt.LayoutManager2

getLayoutAlignmentY

public float getLayoutAlignmentY(java.awt.Container target)

Returns the alignment along the y axis. This specifies how the component would like to be aligned relative to other components. The value should be a number between 0 and 1 where 0 represents alignment along the origin, 1 is aligned the furthest away from the origin, 0.5 is centered, etc.

Specified by:

getLayoutAlignmentY in interface java.awt.LayoutManager2

invalidateLayout

public void invalidateLayout(java.awt.Container target)

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

Specified by:

invalidateLayout in interface java.awt.LayoutManager2

preferredLayoutSize

public java.awt.Dimension preferredLayoutSize(java.awt.Container parent)

Calculates the preferred size dimensions for the specified panel given the components in the specified parent container.

Specified by:

preferredLayoutSize in interface java.awt.LayoutManager

Parameters:

parent - the component to be laid out
