This project does not require frequent updates as it is a look and feel for Swing, which is a stable framework. You can assume it works unless otherwise stated.

Installation

VTerminal is hosted on the JitPack package repository which supports Gradle, Maven, and sbt.

Gradle

Add JitPack to your build.gradle at the end of repositories.

allprojects {
	repositories {
		...
		maven { url 'https://jitpack.io' }
	}
}

Add VTerminal as a dependency.

dependencies {
	implementation 'com.github.Valkryst:VTerminal:2026.11.05'
}

Maven

Add JitPack as a repository.

<repositories>
    <repository>
        <id>jitpack.io</id>
        <url>https://jitpack.io</url>
    </repository>
</repositories>

Add VTerminal as a dependency.

<dependency>
    <groupId>com.github.Valkryst</groupId>
    <artifactId>VTerminal</artifactId>
    <version>2026.11.05</version>
</dependency>

Scala SBT

Add JitPack as a resolver.

resolvers += "jitpack" at "https://jitpack.io"

Add VTerminal as a dependency.

libraryDependencies += "com.github.Valkryst" % "VTerminal" % "2026.11.05"

Media

Please note that all screenshots and videos will look worse than if you were to run the example GUI yourself. This is primarily due to compression.

Screenshots

• JButton
• JCheckBox
• JLabel
• JLayeredPane
• JPasswordField
• JProgressBar
• JRadioButton
• JScrollPane
• VEditorPane
• VPanel
  • With a blur shader.
• VTextArea
• VTextField
• VTextPane

Videos

• Click-through of the example GUI used for testing VTerminal. This covers most, if not all the supported components.

Supported Components

If there is a component that you'd like VTerminal to support, or if you're experiencing any issues with the supported components, then please feel free to open an issue.

• JButton
• JCheckBox
• JEditorPane
• JLabel
• JPanel
• JPasswordField
• JProgressBar
• JRadioButton
• JScrollPane
• JTextArea
• JTextField
• JTextPane
• JToolTip
• VFrame
  • A subclass of JFrame which allows for easier en/disabling of full-screen mode and which has a number of convenience methods.
• VPanel
  • A subclass of JPanel which allows for displaying a 2D grid of characters in which each cell can display a unique fore/background color and code point (Unicode character).

Enhanced Components

Every component rendered by the VTerminal LAF automatically applies a set of high-quality RenderingHints (antialiasing, bicubic interpolation, etc.) to its Graphics2D context before painting. No special subclasses are required — standard Swing components work as-is once the LAF is installed.

The following image shows a JEditorPane rendered with and without high-quality hints side-by-side.

Controlling rendering quality

There are three control levels, applied in order of precedence:

1. Global default — enabled by default; applies to every component.

// Disable high-quality rendering for all components.
VTerminalLookAndFeel.enableHighQualityRendering(false);

// Re-enable it.
VTerminalLookAndFeel.enableHighQualityRendering(true);

2. Per-component override — overrides the global default for a single component.

// Force high-quality rendering for this component regardless of the global default.
component.putClientProperty(VTerminalLookAndFeel.HIGH_QUALITY_RENDERING_KEY, Boolean.TRUE);

// Force low-quality rendering for this component regardless of the global default.
component.putClientProperty(VTerminalLookAndFeel.HIGH_QUALITY_RENDERING_KEY, Boolean.FALSE);

3. Clear the override — removes the per-component override and reverts to the global default.

component.putClientProperty(VTerminalLookAndFeel.HIGH_QUALITY_RENDERING_KEY, null);
