在JavaFX2中移动未修饰的舞台

Question

null

@FXML
protected void onRectanglePressed(MouseEvent event) {
    X = primaryStage.getX() - event.getScreenX();
    Y = primaryStage.getY() - event.getScreenY();
}

@FXML
protected void onRectangleReleased(MouseEvent event) {
    primaryStage.setX(event.getScreenX());
    primaryStage.setY(event.getScreenY());
}

@FXML
protected void onRectangleDragged(MouseEvent event) {
    primaryStage.setX(event.getScreenX() + X);
    primaryStage.setY(event.getScreenY() + Y);
}

Answer 1

我在一个未装饰的窗口中创建了一个动画时钟的示例，您可以拖动它。

示例中的相关代码如下：

// allow the clock background to be used to drag the clock around.
final Delta dragDelta = new Delta();
layout.setOnMousePressed(new EventHandler<MouseEvent>() {
  @Override public void handle(MouseEvent mouseEvent) {
    // record a delta distance for the drag and drop operation.
    dragDelta.x = stage.getX() - mouseEvent.getScreenX();
    dragDelta.y = stage.getY() - mouseEvent.getScreenY();
  }
});
layout.setOnMouseDragged(new EventHandler<MouseEvent>() {
  @Override public void handle(MouseEvent mouseEvent) {
    stage.setX(mouseEvent.getScreenX() + dragDelta.x);
    stage.setY(mouseEvent.getScreenY() + dragDelta.y);
  }
});

...

// records relative x and y co-ordinates.
class Delta { double x, y; } 

代码看起来与您的代码非常相似，所以不太确定为什么您的代码不适合您。
