Question

我有一个未修饰的阶段，我添加了一个包含两个AnchorPains（一个标题栏和一个mainContent）的AnchorPane。为了像普通窗口一样使用这个窗口，我实现了p.e.用于在侧面调整大小并在标题栏上拖动它的功能。为了拖动窗口，我分析了MouseMvents onMouseDragged和onMousePressed（参见下面的源代码）。源代码基本上是可行的。但我有一个问题，如果我移动鼠标太快，窗口将不会移动。一开始，鼠标位于标题栏上。在此之后我将鼠标移动到一侧太快，因此它在窗口外面并且不再被拖动。一旦我回到标题栏，我就可以再次移动它。有没有人建议如何解决这个问题？是否可以将窗口绑定到鼠标光标？

这是我的源代码：

    titleContent.setOnMousePressed(new EventHandler<MouseEvent>() {
        public void handle(MouseEvent mouseEvent) {
                Stage stage = (Stage) titleContent.getScene().getWindow();
                Screen screen = Screen.getPrimary();
                Rectangle2D bounds = screen.getVisualBounds();

                if (mouseEvent.getClickCount()==1){
                // record a delta distance for the drag and drop operation.
                    if (stage.getWidth()==bounds.getMaxX() && stage.getHeight()==bounds.getMaxY()){
                        wasMaximized =true;
                    }

                    if(!wasMaximized){
                        dragDelta.x = stage.getX() - mouseEvent.getScreenX();
                        dragDelta.y = stage.getY() - mouseEvent.getScreenY();
                    }
                    else{
                        dragDelta.x=-1*minWidth/2;
                        dragDelta.y=0;
                        wasMaximized=false;
                    }
                }
        }
    });

    titleContent.setOnMouseDragged(new EventHandler<MouseEvent>() {
        public void handle(MouseEvent mouseEvent) {
                Scene scene = (Scene) titleContent.getScene();
                if (!(mouseEvent.getX() < border || mouseEvent.getX() > scene.getWidth() -border) && !(mouseEvent.getX() < border && mouseEvent.getY() > scene.getHeight() -border)){
                    Stage stage = (Stage) titleContent.getScene().getWindow();
                    Screen screen = Screen.getPrimary();
                    Rectangle2D bounds = screen.getVisualBounds();


                    if (stage.getWidth()==bounds.getMaxX() && stage.getHeight()==bounds.getMaxY()){
                        stage.setWidth(minWidth);
                        stage.setHeight(minHeight);
                    }

                    stage.setX(mouseEvent.getScreenX() + dragDelta.x);
                    stage.setY(mouseEvent.getScreenY() + dragDelta.y);
                }

    }
  });

我找到了解决方案。对于每个人，如何对它感兴趣：问题是titlecontent.setOnMouseDragged函数中的if语句。如果鼠标在给定元素上被拖拽，则只调用该函数。这就是为什么没有必要在那里使用if语句。正确的功能如下：

titleContent.setOnMouseDragged(new EventHandler<MouseEvent>() {
    public void handle(MouseEvent mouseEvent) {
            Scene scene = (Scene) titleContent.getScene();
            if (!(mouseEvent.getX() < border || mouseEvent.getX() > scene.getWidth() -border) && !(mouseEvent.getX() < border && mouseEvent.getY() > scene.getHeight() -border)){
                Stage stage = (Stage) titleContent.getScene().getWindow();
                Screen screen = Screen.getPrimary();
                Rectangle2D bounds = screen.getVisualBounds();


                if (stage.getWidth()==bounds.getMaxX() && stage.getHeight()==bounds.getMaxY()){
                    stage.setWidth(minWidth);
                    stage.setHeight(minHeight);
                }

                stage.setX(mouseEvent.getScreenX() + dragDelta.x);
                stage.setY(mouseEvent.getScreenY() + dragDelta.y);
            }

}

因此，这是一个完整的解决方案，用于拖动和调整未修饰的舞台。希望它有所帮助。
