A Single-Mouse-Gesture Color Chooser for Swing
Ever needed a faster, slicker way to let your users select a color in Swing? I just set up a new java.net project, which produces just such a widget. Press the mouse and a palette pops up; drag over the palette and release when the color is right; use combinations of ctrl/alt/shift to switch palettes (palettes are pluggable if you want to write your own).
The widget is the Quick Color Chooser -
net.dev.java.colorchooser.ColorChooser. It's a simple Swing widget with one property of interest -
color - that is incredibly easy to use.
It's actually been sitting around in
contrib/ on netbeans.org for a couple of years, and the palette code dates back to 2000 - it's a port of a Delphi component I wrote in the mid nineties.
So the code is fairly mature and solid - I just split it out into having a separate UI delegate so it's more Swing-like and the painting behavior is overridable, but it's the same logic as before. Feedback appreciated.
If you want to try it using Matisse in NetBeans, there's a NetBeans module that installs the component in the component palette for immediate drag-and-drop use (created using BeanNetter). The module includes the javadoc.
