colorpicker's Introduction

🎨 Java Swing Color Picker Dialog

A nice color picker using Java Swing that contains a visual color selection and input boxes to enter RGB and HSB values manually:

Two color modes HSV and RGB
Includes an alpha selection
Determine color by hex code
Allows to select color by clicking on color wheel
Minimal dependencies (only SLF4J)
Compatible with Java versions since version 8
Well documented
Easy to use
Completely free and open source

🔧 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

🔨 Building

Please use Maven to build and test the project.

mvn install

This will install the version to your local repository. You can now include it:

<dependency>
    <groupId>org.drjekyll</groupId>
    <artifactId>colorpicker</artifactId>
    <version>1.4.4-SNAPSHOT</version>
 </dependency>

or Gradle with Groovy DSL:

implementation 'org.drjekyll:fontchooser:1.4.4-SNAPSHOT'

or Gradle with Kotlin DSL:

implementation("org.drjekyll:fontchooser:1.4.4-SNAPSHOT")

colorpicker's Issues

[BUG] Color slider doesn't update when using setColor()

Describe the bug
setColor() doesn't seem to update the position of the color slider (neither hue, brightness or saturation is updated)

Code snippets

public void setAccentColor(Color accentColor) {
    accentColorPicker.setColor(accentColor);
}

[BUG] NPE on using slider

Describe the bug
An NullPointerException is thrown on using the slider (tried in UiBooster test class)

Code snippets
Used this code

Expected behavior
Changing the saturation of the color and not throw an exception 😊

[BUG] Illegal argument exception when color wheel is tiny

Describe the bug
When the component gets too small such as when the frame is resized, the color wheel disappears entirely. However, the selection handle/circle is still visible and creates an exception when you click on it.

Exception in thread "AWT-EventQueue-0" java.lang.IllegalArgumentException: The saturation value (-5.3851647) must be between [0,1]
	at com.bric.colorpicker.ColorPickerPanel.setHSB(ColorPickerPanel.java:460)
	at com.bric.colorpicker.ColorPickerPanel$ColorPickerMouseInputListener.mousePressed(ColorPickerPanel.java:682)

[REQUEST] Horizontal layout for controls

By default the controls and preview swatch are displayed to the right of the color wheel. I'd like to see more customization available by default, specifically an option to have all the modes displayed below the color wheel by default laid out horizontally rather than vertically. It would save a lot of time :)

[BUG] Localization not implemented for ColorPicker/Option

Describe the bug
The ColorPicker class is not using localization.

Code snippets

ResourceBundle.getBundle("com.bric.colorpicker.resources.ColorPicker"); // This is not calling the getBundle with a local.

Expected behavior

ResourceBundle.getBundle("com.bric.colorpicker.resources.ColorPicker", local); // local being the current active localization

[BUG] NullPointerException

I have a colour picker inside a dockable frame from DockingFrames. It starts off minimized and when it is shown the colour picker throws an NPE
