🔧 Usage

Include the following dependency to your project:

<dependency>
  <groupId>org.drjekyll</groupId>
  <artifactId>colorpicker</artifactId>
  <version>2.0.1</version>
</dependency>

Use the class com.bric.colorpicker.ColorPicker as an entry point. You can easily initialize the panel using

ColorPicker colorPicker = new ColorPicker(true, true);
colorPicker.addColorListener(colorModel -> System.out.println(colorModel.getColor()));

This creates a color picker component with expert controls and opacity settings. If the user selects a color, the color listener will be notified.

🌐 Localization

The color picker supports localization. You can set the locale by passing it to the constructor:

ColorPicker colorPicker = new ColorPicker(true, true, Locale.FRENCH);
// or
ColorPickerDialog.showDialog(null, Color.GREEN, Locale.FRENCH);

Currently, the following languages are supported:

  • English
  • Español
  • Français
  • Deutsch
  • Português
  • Русский

Please use Maven to build and test the project.
