为什么Mouse Pressed Event在JavaFX的TextArea中不起作用？

Question

这是我的代码：

@FXML private TextArea txtconfig;
public void handleMousePressed(MouseEvent mouseEvent) {
        txtconfig.setOnMousePressed(new EventHandler<MouseEvent>() {
            @Override
            public void handle(MouseEvent event) {
                System.out.println("PRESSED");
            }
        });
    }

在FXML中：

TextArea fx:id="txtconfig"  style="-fx-font-size:10pt; -fx-font-family:Consolas"
              maxWidth="Infinity" maxHeight="Infinity" VBox.vgrow="ALWAYS"
              onMousePressed="#handleMousePressed"/>

然而，setOnMouseClicked正在努力保持一切相同。只有onMousePressed在FXML中更改为onMouseClicked。

public void handleMouseClicked(MouseEvent mouseEvent) {
        txtconfig.setOnMouseClicked(new EventHandler<MouseEvent>() {
            @Override
            public void handle(MouseEvent event) {
                 System.out.println("Clicked");
            }
        });

    }

正如this answer中所建议的那样，如果你确实需要ÈventFilter事件（这似乎是由控件本身使用），你可以安装MousePressed：

txtconfig.addEventFilter(
    MouseEvent.MOUSE_PRESSED,
    new EventHandler<MouseEvent>() {
        @Override
        public void handle(MouseEvent event) {
            System.out.println("PRESSED");
        }
    }
);
