在SWT中嵌入JavaFX的一个问题

[jdgdf566]

import javafx.embed.swt.FXCanvas;
import javafx.scene.Parent;
import javafx.scene.Scene;
import org.eclipse.swt.SWT;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Shell;

/**

 */
public class NewMain {

    static Scene scene;

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        Display display = new Display();
        Shell shell = new Shell(display, SWT.CLOSE | SWT.ON_TOP);
        //shell.setAlpha(100);
        shell.setSize(500, 500);
        //shell.setBackgroundMode(SWT.INHERIT_FORCE);
        //shell.setBackground(new Color(display, 255, 0, 0));
        //shell.setLayout(new FillLayout());
        //-------------------------------
        FXCanvas fXCanvas = new FXCanvas(shell, SWT.NONE);
        //<Scene
        Parent root = new Parent() {
        };
        scene = new Scene(root, 500, 500);
        scene.setFill(javafx.scene.paint.Color.color(0, 0, 0, 0));
        fXCanvas.setScene(scene);
        fXCanvas.setSize(500, 500);
        //Scene>
        //--------------------------------
        shell.open();
        while (!shell.isDisposed()) {
            if (!display.readAndDispatch()) {
                display.sleep();
            }
        }
        display.dispose();
    }

}

我需要让场景scene的背景透明，即第33行：
scene.setFill(javafx.scene.paint.Color.color(0, 0, 0, 0));
但是却是黑色。

怎么这么冷清，都忙着放假吗？

沉了？不知道就说声不知道也行，没有人看见帖子是怎么的？

是不是shell的背景色

不是

这个类javax.swing.JComponent下面的一个方法setOpaque，在api中的解释如下： public void setOpaque(boolean isOpaque) If true the component paints every pixel within its bounds. Otherwise, the component may not paint some or all of its pixels, allowing the underlying pixels to show through. The default value of this property is false for JComponent. However, the default value for this property on most standard JComponent subclasses (such as JButton and JTree) is look-and-feel dependent. Parameters: isOpaque - true if this component should be opaque 这个是设置透明效果的方法，运用的话要自己灵活运用，你可以先去试试

必须操作背景颜色，模糊度会是容器中的所有东西都半透明。
