Class ColorTip

Object
  ColorTip

final class ColorTip
extends Object

Calls user's attention to an aspect of the GUI (much like a ToolTip) by changing the background color of a component (typically a JLabel) for a few seconds; the component will always revert to its original background color after a short time has passed.

Example use case:

 //no initial delay, and show the new color for 2 seconds only
 ColorTip tip = new ColorTip(0, 2, someLabel, temporaryColor);
 tip.start();

Uses a daemon thread, so this class will not prevent a program from terminating. Will not lock the GUI.

Constructor Detail

ColorTip

ColorTip(int aInitialDelay,
         int aActivationInterval,
         JComponent aComponent,
         Color aTempColor)

Constructor.

Parameters:

aInitialDelay - number of seconds to wait before changing the background color of aComponent, and must be in range 0..60 (inclusive).

aActivationInterval - number of seconds to display aTempColor, and must be in range 1..60 (inclusive).

aComponent - GUI item whose background color will be changed.

aTempColor - background color which aComponent will take for aActivationInterval seconds.

Method Detail

start

void start()

Temporarily change the background color of the component, without interfering with the user's control of the gui, and without preventing program termination.

If the target temporary color is the same as the current background color, then do nothing. (This condition occurs when two ColorTip objects are altering the same item at nearly the same time, such that they "overlap".)
