Constructor Detail

ColorChooser

public ColorChooser(java.awt.Frame parent)
Displays a dialog in which the user can select a color and an alpha (transparency) value.

A color chooser that allows users to pick a color in three different manners. The color selection is provided by a JColorChooser pane.

The dialog Can be called with ColorChooser fc = new ColorChooser(this); if a frame is avialable or it can be called with: ColorChooser fc = new ColorChooser(null); if a frame is not available.

If a frame is provided, the dialog is centered over that frame. Otherwise, if a null is passed, the dialog is positioned 20 pixels down and to the right of the upper left corner of the display screen.

This dialog is an adaptation of the font chooser presented in Java Swing by Robert Eckstein, Marc Loy & Dave Wood, O'Reilly, Sebastopol, CA 1998, ISBN 1-56592-455-X

Parameters:
parent - The Frame from which the dialog was called.
Method Detail

getNewColor

public java.awt.Color getNewColor()
Returns the color that was selected by the user.

Returns:
A Color object with red, green, blue and alpha set. The alpha/transparency value is constrained to fall beween (inclusive) 1 and 255. If an invalid value is entered the program advises the user and sets the value to 255. The user then has the opportunity to enter another legal value.

Note: The alpha values set by the user do not change the transparency of the text shown by the color chooser but are returned in the color object.


toString

public java.lang.String toString()
Overrides:
toString in class java.awt.Component
Returns:
Provides a string representation of the selected color and color-alpha.

Example: java.awt.Color[r=255,g=51,b=51]Alpha=179
