public class LwColorPanel

extends LwPanel

implements LwActionListener, TextListener

This panel provides ability to customize color using different ways :

• By the specifying RGB color components in the text fields.
• By the specifying RGB color components using sliders.
• By the selecting one of the predefined color. The predefined colors set is specified by the properties. The properties has the following format:

           colors.rows=[number of rows]
           colors.cols=[number of columns]
  
           colors.row.[row number]=[red1],[green1],[blue1];[red2],[green2],[blue2]...[redN],[greenN],[blueN]
           ...
        

The panel reads fields titles as the following LwVCL resources:

cd.predef	predefined color panel title
cd.selected	selected color field title
cd.red	red color field title
cd.green	green color field title
cd.blue	blue color field title

Constructor Detail

LwColorPanel

public LwColorPanel()

Constructs a color panel. In this case the predefined colors set is loaded by "colors.properties" properties file.

LwColorPanel

public LwColorPanel(java.awt.Color c,
                    java.lang.String props)

Constructs a color panel with the given selected color and the given properties file to specify a predefined colors set. The properties file will be fetched relatively LwVCL base (the current base can be got by the LwToolkit.getResourcesBase method) directory.

Parameters:

c - the given selected color.

props - the given properties file.

LwColorPanel

public LwColorPanel(java.awt.Color c,
                    java.util.Properties p)

Constructs a color panel with the given selected color and the given properties to specify a predefined colors set.

Parameters:

c - the given selected color.

p - the given properties.

addActionListener

public void addActionListener(LwActionListener l)

Adds the specified action listener to receive action events from this component. The action event is performed whenever a selected color has been changed. The action event stores the new color value in the event data field.

Parameters:

l - the specified action listener.

removeActionListener

public void removeActionListener(LwActionListener l)

Removes the specified action listener so it no longer receives action events from this component.

Parameters:

l - the specified action listener.

public void actionPerformed(java.lang.Object target,
                            java.lang.Object data)

Description copied from interface: LwActionListener

Invoked when an action event occurred.

Specified by:

actionPerformed in interface LwActionListener

Following copied from interface: org.zaval.lw.event.LwActionListener

Parameters:

src - the specified source where the event has been originated.

data - the event data.

setSelectedColor

public void setSelectedColor(java.awt.Color c)

Sets the specified color as the selected color.

Parameters:

c - the specified color to set as selected.

getSelectedColor

public java.awt.Color getSelectedColor()

Gets the current selected color.

Returns:

a current selected color.

textRemoved

public void textRemoved(TextEvent e)

Description copied from interface: TextListener

Following copied from interface: org.zaval.data.event.TextListener

Parameters:

e - the text event.

textInserted

public void textInserted(TextEvent e)

Description copied from interface: TextListener

Invoked when a new text has been inserted in the text.

Specified by:

textInserted in interface TextListener

Following copied from interface: org.zaval.data.event.TextListener

Parameters:

e - the text event.

textUpdated

public void textUpdated(TextEvent e)

Description copied from interface: TextListener

Invoked when the text has been updated.

Specified by:

textUpdated in interface TextListener

Following copied from interface: org.zaval.data.event.TextListener

Parameters:

e - the text event.

getDefaultLayout

protected LwLayout getDefaultLayout()

Description copied from class: LwPanel
