JavaFX-将GridPane膨胀到父级的大小

Question

    //Grid layout
    GridPane grid = new GridPane();
    grid.setPrefSize(STAGE_WIDTH, STAGE_HEIGHT);
    grid.setMaxSize(Region.USE_COMPUTED_SIZE, Region.USE_COMPUTED_SIZE);
    grid.setMinSize(STAGE_WIDTH, STAGE_HEIGHT);

    //grid.minWidth(STAGE_WIDTH);
    //grid.minHeight(STAGE_HEIGHT);

    grid.setGridLinesVisible(true);
    grid.setAlignment(Pos.CENTER);
    grid.setHgap(10);
    grid.setVgap(10);
    grid.setPadding(new Insets(25, 25, 25, 25));

    //Text
    final Text count = new Text("Count");
    grid.add(count,0,0);

    final Text total = new Text("Total");
    grid.add(total,1,0);

    Scene scene = new Scene(grid, STAGE_WIDTH, STAGE_HEIGHT);
    primaryStage.setScene(scene);
    primaryStage.show();

有人知道如何成功编程这个简单的属性吗？占据整个窗口的网格窗格？我错过了什么？

谢谢LD

删除所有这些

grid.setPrefSize(STAGE_WIDTH, STAGE_HEIGHT);
grid.setMaxSize(Region.USE_COMPUTED_SIZE, Region.USE_COMPUTED_SIZE);
grid.setMinSize(STAGE_WIDTH, STAGE_HEIGHT);
grid.minWidth(STAGE_WIDTH);
grid.minHeight(STAGE_HEIGHT);

并将ColumnConstraints与RowConstraints（可选）一起使用：

ColumnConstraints cc = new ColumnConstraints(100, 100, Double.MAX_VALUE, 
                                     Priority.ALWAYS, HPos.CENTER, true);
grid.getColumnConstraints().addAll(cc, cc);

RowConstraints rc = new RowConstraints(20, 20, Double.MAX_VALUE, 
                                     Priority.ALWAYS, VPos.CENTER, true);
grid.getRowConstraints().addAll(rc, rc);

通过为每个单元格添加单独的列和行约束，您将以这种方式获得对它的更多控制。更详细的解释请参考javadocs。
