VFlowLayout

public VFlowLayout()

Method Detail

preferredLayoutSize

public Dimension preferredLayoutSize(Container parent)

Specified by:

preferredLayoutSize in interface LayoutManager

minimumLayoutSize

public Dimension minimumLayoutSize(Container parent)

Specified by:

minimumLayoutSize in interface LayoutManager

maximumLayoutSize

public Dimension maximumLayoutSize(Container parent)

Specified by:

maximumLayoutSize in interface LayoutManager2

layoutContainer

public void layoutContainer(Container parent)

Lays out the container by stacking the components in one vertical column. Stretches each component to the width of the container, does not stretch or shrink the components vertically.

Specified by:

layoutContainer in interface LayoutManager

calculateLayoutSize

protected Dimension calculateLayoutSize(Container parent)

Total up the height of each component in the container plus the insets of the container itself. Width is width of the container

getLayoutSize

protected Dimension getLayoutSize(Container parent)

The layout size is not changed by this layout manager so we can cache the the dimensions. This method only recalculates them if the cache is null which may happen by the invalidateLayout method.
