我正在尝试按下按钮时创建一个新的Stage
。
它可以工作,但问题是我希望此Stage
是完全透明的,并让我们看到屏幕后面的内容。
代码
Dimension Sizescreen = Toolkit.getDefaultToolkit().getScreenSize();
//Main stage with option menu
Pane window = new Pane();
Scene scene = new Scene(window);
stage.setTitle("Notification Extender");
//Create the button SetLooker
Button SetLooker = new Button("Set Looker");
//Add a Event when pressed
SetLooker.setOnAction(new EventHandler<ActionEvent>() {
public void handle(ActionEvent e) {
//Create a sub-Stage
Pane subwindow = new Pane();
Scene subscene = new Scene(subwindow);
Stage substage = new Stage();
substage.setTitle("Notification Extender");
//Set this subStage Transparent
substage.initStyle(StageStyle.TRANSPARENT);
subscene.setFill(Color.TRANSPARENT);
substage.setWidth(Sizescreen.getWidth());
substage.setHeight(Sizescreen.getHeight());
substage.setX(0);
substage.setY(0);
//Create a a graphique element
Rectangle redrec = new Rectangle(120,40,50,50);
redrec.setStroke(Color.RED);
redrec.setStrokeWidth(2);
redrec.setFill(Color.TRANSPARENT);
//Add the graphique element to the sub-stage
subwindow.getChildren().add(redrec);
//Show the sub-stage
substage.setScene(subscene);
substage.show();
}
});
//Add the button to the main stage
window.getChildren().add(SetLooker);
//Show the main stage
stage.setScene(scene);
stage.show();
问题是,当我按下按钮时,它显示了舞台,但它根本不透明,完全是白色的。
我也尝试过更改主Stage
,但是一旦显示就无法更改。

您还需要从新场景的根部移除背景:
subwindow.setBackground(null);
