Parameters:

dir - the specified orientation.

gap - the specified gap.

componentAdded

public void componentAdded(java.lang.Object id,
                           Layoutable lw,
                           int index)

Description copied from interface: LwLayout

Invoked when the specified layoutable component was added to the layout container (that uses the layout manager). The specified constraints, layoutable component and child index are passed as arguments into the method.

Specified by:

componentAdded in interface LwLayout

Following copied from interface: org.zaval.lw.LwLayout

Parameters:

id - the layoutable component constraints.

lw - the layoutable component that has been added.

index - the child index.

componentRemoved

public void componentRemoved(Layoutable lw,
                             int index)

Description copied from interface: LwLayout

Invoked when the specified layoutable component was removed from the layout container, that uses the layout manager.

Specified by:

componentRemoved in interface LwLayout

Following copied from interface: org.zaval.lw.LwLayout

Parameters:

lw - the layoutable component that has been removed.

index - the child component index.

layout

public void layout(LayoutContainer target)

Description copied from interface: LwLayout

Lays out the child layoutable components inside the layout container.

Specified by:

layout in interface LwLayout

Following copied from interface: org.zaval.lw.LwLayout

Parameters:

target - the layout container.

calcPreferredSize

public java.awt.Dimension calcPreferredSize(LayoutContainer target)

Description copied from interface: LwLayout

Calculates the preferred size dimension for the layout container. The method has to calculate "pure" preferred size, it means that container insets should not be taken into account.

Specified by:

calcPreferredSize in interface LwLayout

Following copied from interface: org.zaval.lw.LwLayout

Parameters:

target - the layout container.

Returns:

a "pure" preferred size.
