• Two themes in both light and dark variants.
• Simple and intuitive color system based on the GitHub Primer guidelines.
• Fully customizable. Easily change global accent (brand) color or individual control via looked-up color variables.

• Custom themes support. Compile your own theme from existing SASS sources.
• Additional controls that essential for modern GUI development.
• Beautiful demo app:
  • Preview all supported themes.
  • Test every feature of each existing control and check source code directly in the app to learn how to implement it.

Getting started

Requirements: JavaFX 17+ (because of data-url support).

Maven:

<dependency>
    <groupId>io.github.mkpaz</groupId>
    <artifactId>atlantafx-base</artifactId>
    <version>2.0.0</version>
</dependency>

Gradle:

repositories {
    mavenCentral()
}

dependencies {
    implementation 'io.github.mkpaz:atlantafx-base:2.0.0'
}

Set a theme:

public class Launcher extends Application {

    public static void main(String[] args) {
        launch(args);
    }

    @Override
    public void start(Stage stage) {
        // find more themes in 'atlantafx.base.theme' package
        Application.setUserAgentStylesheet(new PrimerLight().getUserAgentStylesheet());
        Application.setUserAgentStylesheet(new PrimerDark().getUserAgentStylesheet());

        // the rest of the code ...
    }
}

Local Installation

If you don't want to use additional dependencies, you can download compiled CSS themes from the GitHub Releases. Unpack AtlantaFX-*-themes.zip and place it to your project's classpath.

Set CSS theme:

Application.setUserAgentStylesheet(/* path to the CSS file */);

Or use Java property:

-Djavafx.userAgentStylesheetUrl=[URL]

Contributing

Contributions are always welcome! Contributing can mean many things such as participating in discussion or proposing changes. Feel free to open an issue if you've found a bug or want to raise a question, or discuss a possible feature.

Please, note that AtlantaFX is primarily CSS theme library. Controls and skins support will probably grow over time, but creating yet another control's library is not a main goal.

Here are some areas, where you can help the project:

1. Fixing or reporting bugs. Please, check OpenJFX bug tracker first if the bug you're experiencing isn't related to CSS or custom AtlantaFX control.
2. Adding or improving control samples, which helps people to learn more about existing controls and we can also test how controls look and work with different themes.
3. Adding or improving widget samples, which provides basic examples of how to implement some conventional UI components.
4. Adding or improving app showcases, which demonstrates how AtlantaFX looks in real-world that helps to find more areas for improvement.
5. Improving docs, because good docs is the face of the project.
6. Advertising the project.
