Create Graphical User Interfaces in Java using HTML Java
Using this library is straightforward:
- Instantiate JHtmlBridge:
JHtmlBridge htmlBridge = new JHtmlBridge("www", "Example", 500, 500);- Define Java bindings:
public class MyButtonHandler {
public void exampleButtonClick() {
System.out.println("Hello, World!");
}
}
// ...
htmlBridge.bind("example", new MyButtonHandler());- Launch the Window
htmlBridge.launch();In this example the html files are stored in the www folder. Sample index.html
<!DOCTYPE html>
<html>
<body>
<h1>Hello, World!</h1><br>
<button onclick="example.exampleButtonClick()">Click Me!</button>
</body>
</html>If you want to pass arguments to your methods, simply pass the value to the method e.g.
public void exampleButtonClick(String name) {
System.out.println("Hello, " + name);
}
//...
<button onclick="example.exampleButtonClick('John Smith')">Click Me!</button>To retrieve the text content of an element, you can use the JHtmlBridgeHelper.
JHtmlBridgeHelper helper = htmlBridge.getHelper();
String content = helper.getContentForElement("someId");Important: After cloning the repository, run the following command to install the necessary pre-commit hooks:
