JColorChooser provides a pane of controls designed to allow a user to manipulate and select a color. For information about using color choosers, see
How to Use Color Choosers
, a section in The Java Tutorial.
This class provides three levels of API:
-
A static convenience method which shows a modal color-chooser dialog and returns the color selected by the user.
-
A static convenience method for creating a color-chooser dialog where ActionListeners can be specified to be invoked when the user presses one of the dialog buttons.
-
The ability to create instances of JColorChooser panes directly (within any container). PropertyChange listeners can be added to detect when the current "color" property changes.
Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeans
TM
has been added to the java.beans package. Please see

public String getUIClassID()
-
Returns the name of the L&F class that renders this component.
-
-
Overrides:
-
getUIClassID
in class
JComponent
-
-
Returns:
-
the string "ColorChooserUI"
-
See Also:
-
JComponent.getUIClassID()
,

getColor
public Color getColor()
-
Gets the current color value from the color chooser. By default, this delegates to the model.
-
-
-
Returns:
-
the current color value of the color chooser
setColor
public void setColor(Color color)
-
Sets the current color of the color chooser to the specified color. The ColorSelectionModel will fire a ChangeEvent
-
-
-
Parameters:
-
color - the color to be set in the color chooser
-
See Also:
-
Container.addPropertyChangeListener(java.beans.PropertyChangeListener)
JComponent.addPropertyChangeListener(java.beans.PropertyChangeListener)
setColor
public void setColor(int r,
int g,
int b)
-
Sets the current color of the color chooser to the specified RGB color. Note that the values of red, green, and blue should be between the numbers 0 and 255, inclusive.
-
-
-
Parameters:
-
r - an int specifying the amount of Red
-
g - an int specifying the amount of Green
-
b - an int specifying the amount of Blue
-
Throws:
-
IllegalArgumentException
- if r,g,b values are out of range
-
See Also:
-
Color
setColor
public void setColor(int c)
-
Sets the current color of the color chooser to the specified color.
-
-
-
Parameters:
-
c - an integer value that sets the current color in the chooser where the low-order 8 bits specify the Blue value, the next 8 bits specify the Green value, and the 8 bits above that specify the Red value.
setDragEnabled
public void setDragEnabled(boolean b)
-
Sets the dragEnabled property, which must be true to enable automatic drag handling (the first part of drag and drop) on this component. The transferHandler property needs to be set to a non-null value for the drag to do anything. The default value of the dragEnabled property is false.
When automatic drag handling is enabled, most look and feels begin a drag-and-drop operation when the user presses the mouse button over the preview panel. Some look and feels might not support automatic drag and drop; they will ignore this property. You can work around such look and feels by modifying the component to directly call the exportAsDrag method of a TransferHandler.
-
-
-
Parameters:
-
b - the value to set the dragEnabled property to
-
Throws:
-
HeadlessException
- if b is true and GraphicsEnvironment.isHeadless() returns true
-

-
1.4
