All Implemented Interfaces:

java.awt.image.ImageObserver, java.awt.MenuContainer, java.io.Serializable, javax.accessibility.Accessible

public class FormDebugPanel
extends javax.swing.JPanel

A panel that paints grid bounds if and only if the panel's layout manager is a FormLayout. You can tweak the debug paint process by setting a custom grid color, painting optional diagonals and painting the grid in the background or foreground.

This class is not intended to be extended. However, it is not marked as final to allow users to subclass it for debugging purposes. In general it is recommended to use JPanel instances, not extend them. You can see this implementation style in the Forms tutorial classes. Rarely there's a need to extend JPanel; for example if you provide a custom behavior for #paintComponent or #updateUI.

Constructor Detail

FormDebugPanel

public FormDebugPanel()

Constructs a FormDebugPanel with all options turned off.

FormDebugPanel

public FormDebugPanel(FormLayout layout)

Constructs a FormDebugPanel on the given FormLayout instance that paints the grid in the foreground and paints no diagonals.

Parameters:

layout - the panel's FormLayout instance

FormDebugPanel

public FormDebugPanel(boolean paintInBackground,
                      boolean paintDiagonals)

Constructs a FormDebugPanel on the given FormLayout using the specified settings that are otherwise turned off.

Parameters:

paintInBackground - true to paint grid lines in the background, false to paint the grid in the foreground

paintDiagonals - true to paint diagonals, false to not paint them

FormDebugPanel

                      boolean paintInBackground,
                      boolean paintDiagonals)

Constructs a FormDebugPanel on the given FormLayout using the specified settings that are otherwise turned off.

Parameters:

layout - the panel's FormLayout instance

paintInBackground - true to paint grid lines in the background, false to paint the grid in the foreground

paintDiagonals - true to paint diagonals, false to not paint them

Method Detail

setPaintInBackground

public void setPaintInBackground(boolean b)

Specifies to paint in background or foreground.

Parameters:

b - true to paint in the background, false for the foreground

setPaintDiagonals

public void setPaintDiagonals(boolean b)

Enables or disables to paint the panel's diagonals.

setGridColor

public void setGridColor(java.awt.Color color)

Sets the debug grid's color.

Parameters:

color - the color used to paint the debug grid

paintComponent

protected void paintComponent(java.awt.Graphics g)

paint(Graphics)

paint

public void paint(java.awt.Graphics g)
