在javafx中更新动态网格窗格。一旦绘制完成，它就不会再次使用更新后的参数(行、列)进行更新

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.GridPane;
import javafx.stage.Stage;

public class DynamicGridPaneExample extends Application {

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

        // 添加控件到网格窗格的特定单元格
        Button button1 = new Button("Button 1");
        gridPane.add(button1, 0, 0);

        Button button2 = new Button("Button 2");
        gridPane.add(button2, 1, 0);

        Button button3 = new Button("Button 3");
        gridPane.add(button3, 0, 1);

        // 设置列和行的约束
        gridPane.getColumnConstraints().get(0).setPercentWidth(50);
        gridPane.getColumnConstraints().get(1).setPercentWidth(50);
        gridPane.getRowConstraints().get(0).setPercentHeight(50);
        gridPane.getRowConstraints().get(1).setPercentHeight(50);

        // 设置列和行之间的间距
        gridPane.setHgap(10);
        gridPane.setVgap(10);

        // 设置是否显示网格线
        gridPane.setGridLinesVisible(true);

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

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