Class FormLayout

java.lang.Object
  |
  +--allensoft.gui.FormLayout

All Implemented Interfaces:

java.awt.LayoutManager, java.awt.LayoutManager2

public class FormLayout

extends java.lang.Object

implements java.awt.LayoutManager2

A powerful layout manager that lays out componentents in a form fashion. Typically, a label is to the left of a field and the left edges of all fields line up. Components with even indexes are assumed to be labels and components with odd indexes are assumed to be fields.

Constructor Summary

FormLayout()
Creates a new FlowLayout with spacings of 5 and labels left aligned and centred vertically and fields left aligned and centred vertically.

FormLayout(int nHorizSpacing, int nVertSpacing)
Creates a new FormLayout with labels left aligned and centred vertically and fields left aligned and centred vertically.

FormLayout(int nHorizSpacing, int nVertSpacing, float fLabelHorizAlignment, float fLabelVertAlignment, float fFieldHorizAlignment, float fFieldVertAlignment)
Creates a new FormLayout.

Constructor Detail

FormLayout

public FormLayout(int nHorizSpacing,
                  int nVertSpacing,
                  float fLabelHorizAlignment,
                  float fLabelVertAlignment,
                  float fFieldHorizAlignment,
                  float fFieldVertAlignment)

Creates a new FormLayout.

Parameters:

nHorizSpacing - the spacing between a label and a field

nVertSpacing - the spacing between fields

fLabelHorizAlignment - see setLabelHorizAlignment(float)

fLabelVertAlignment - see setLabelVertAlignment(float)

fFieldHorizAlignment - see setFieldHorizAlignment(float)

fFieldVertAlignment - see setFieldVertAlignment(float)

FormLayout

public FormLayout(int nHorizSpacing,
                  int nVertSpacing)

Creates a new FormLayout with labels left aligned and centred vertically and fields left aligned and centred vertically.

Parameters:

nHorizSpacing - the spacing between a label and a field

nVertSpacing - the spacing between fields

FormLayout

public FormLayout()

Creates a new FlowLayout with spacings of 5 and labels left aligned and centred vertically and fields left aligned and centred vertically.

Method Detail

getHorizSpacing

public int getHorizSpacing()

Gets the spacing between labels and fields.

setHorizSpacing

public void setHorizSpacing(int n)

Sets the spacing between labels and fields.

getVertSpacing

public int getVertSpacing()

Gets the vertical spacing between fields.

setVertSpacing

public void setVertSpacing(int n)

Gets the vertical spacing between fields.

getLabelHorizAlignment

public float getLabelHorizAlignment()

Gets the horizontal alignment for labels. This specifies how the labels should be aligned horizontally. The value should be a number between 0 and 1 where 0 represents left alignment, 1 is right alignment, 0.5 is centered, etc.

setLabelHorizAlignment

public void setLabelHorizAlignment(float f)

Sets the horizontal alignment for labels. This specifies how the labels should be aligned horizontally. The value should be a number between 0 and 1 where 0 represents left alignment, 1 is right alignment, 0.5 is centered, etc.

getLabelVertAlignment

public float getLabelVertAlignment()

setLabelVertAlignment
