All Implemented Interfaces:

LayoutManager, LayoutManager2, Serializable

public class Form
extends com.HawkinsSoftware.FormLayout
implements LayoutManager2, Serializable

This class extends FormLayout from HawkinsSoftware. It allows you to layout compoents in a "label/field" layout, but it allows you to use any component for the label/field. Components are added to a specified row and column and can span multiple rows. It uses FormConstraints to specify how the compoents are to be laid out.

Constructor Detail

Form

public Form()

Creates a new Form with default gaps horizontally and vertically between components and no external gaps.

Parameters:

p - the container that is needs to be laid out

Form

public Form(int intHGap,
            int intVGap,

Method Detail

addLayoutComponent

public void addLayoutComponent(Component comp,
                               Object constraints)

Adds the given compoent to the layout using the given constraints.

Specified by:

addLayoutComponent in interface LayoutManager2

Parameters:

comp - the component to be added to the layout

constraints - the constraints to be applied to the component

maximumLayoutSize

public Dimension maximumLayoutSize(Container target)

Returns the maximum size for this layout.
