尝试用JavaFX网格窗格推断鼠标拖动的位置

import javafx.application.Application;
import javafx.event.EventHandler;
import javafx.scene.Scene;
import javafx.scene.input.MouseEvent;
import javafx.scene.layout.GridPane;
import javafx.stage.Stage;

public class MouseDragPosition extends Application {

    @Override
    public void start(Stage primaryStage) {
        GridPane gridPane = new GridPane();

        gridPane.setOnMouseDragged(new EventHandler<MouseEvent>() {
            @Override
            public void handle(MouseEvent event) {
                double mouseX = event.getX();
                double mouseY = event.getY();
                int column = GridPane.getColumnIndex(gridPane);
                int row = GridPane.getRowIndex(gridPane);
                System.out.println("Mouse dragged at position: (" + column + ", " + row + ")");
            }
        });

        Scene scene = new Scene(gridPane, 400, 400);
        primaryStage.setScene(scene);
        primaryStage.show();
    }

    public static void main(String[] args) {
        launch(args);
    }
}
