透明背景-Transparent Background · 前端开发手册

在JxBrowser 6.10及更高版本中，有一些功能允许在网页上启用透明背景支持。以下示例演示了如何启用透明背景支持： ``` import com.teamdev.jxbrowser.chromium.Browser; import com.teamdev.jxbrowser.chromium.BrowserPreferences; import com.teamdev.jxbrowser.chromium.BrowserType; import com.teamdev.jxbrowser.chromium.swing.BrowserView; import javax.swing.*; import java.awt.*; /** * This sample demonstrates how to create Browser instance with transparent background. */ public class TransparentPageSample { public static void main(String[] args) { Browser browser = new Browser(BrowserType.LIGHTWEIGHT); // Enable support of transparent background BrowserPreferences preferences = browser.getPreferences(); preferences.setTransparentBackground(true); browser.setPreferences(preferences); BrowserView view = new BrowserView(browser); JPanel panel = new JPanel(); panel.setLayout(new BorderLayout()); panel.setBackground(new Color(0, 150, 255, 255)); panel.add(view, BorderLayout.CENTER); JFrame frame = new JFrame(); frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE); frame.add(panel, BorderLayout.CENTER); frame.setSize(300, 200); frame.setLocationRelativeTo(null); frame.setVisible(true); browser.loadHTML("<html><body>" + "<div style='background: yellow; opacity: 0.7;'>\n" + " This text is in the yellow half-transparent div and should " + " appear as in the green due to the blue JPanel behind." + "</div>\n" + "<div style='background: red;'>\n" + " This text is in the red opaque div and should appear as is." + "</div>\n" + "<div>\n" + " This text is in the non-styled div and should appear as in " + " the blue due to the blue JPanel behind." + "</div>\n" + "</body></html>"); } } ```
