我创建了一个应用程序,它使用 GridPanel 生成一个带有网格图案的板,该板由在 javaFX 中保存方形对象的节点组成。以下是当前输出:
我想知道在点击节点后如何返回节点的坐标。我知道我必须使用各种动作侦听器,但在节点坐标方面我并不完全熟悉。
下面是目前的源代码,非常感谢。
import javafx.application.Application;
import javafx.scene.Group;
import javafx.scene.Scene;

import javafx.scene.shape.Rectangle;
import javafx.stage.Stage;
public class MainApp extends Application {
private final double windowWidth = 1000;
private final double windowHeight = 1000;
/*n is amount of cells per row
m is amount of cells per column*/
private final int n = 50;
private final int m = 50;
double gridWidth = windowWidth / n;
double gridHeight = windowHeight / m;
MyNode[][] playfield = new MyNode[n][m];
public static void main(String[] args) {
launch(args);
}
@Override
public void start(Stage primaryStage) {
Group root = new Group();
// initialize playfield
for( int i=0; i < n; i++) {
for( int j=0; j < m; j++) {
// create node
MyNode node = new MyNode( i * gridWidth, j * gridHeight, gridWidth, gridHeight);
// add node to group
root.getChildren().add( node);
// add to playfield for further reference using an array
playfield[i][j] = node;
}
}
Scene scene = new Scene( root, windowWidth, windowHeight);
primaryStage.setScene( scene);
primaryStage.show();
primaryStage.setResizable(false);
primaryStage.sizeToScene();
}
