重绘JavaFX窗口

Question

javafx应用程序的REPAINT打开窗口有没有选项？我需要在循环中重新绘制这个窗口（i = 1000）并检查从重新绘制开始到重新绘制结束的时间。

我不知道在哪里使用哪种方法。非常感谢

public class JavaFxCombobox extends Application {

private static final int numberOFTestingLoops = 100;

private List<Long> resultOfAnalysisRepaint = new ArrayList<Long>();
private List<Double> resultOfAnalysisMemory = new ArrayList<Double>();

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

@Override
public void start(Stage primaryStage) {

    GridPane gridPane = new GridPane();
    int counter = 0;

    List<ComboBox<String>> comboboxes = new ArrayList<ComboBox<String>>();

    for (int i = 0; i < 30; i++) {
        for (int j = 0; j < 30; j++) {

            counter++;

            ComboBox<String> comboBox = new ComboBox<String>();
            comboBox.getItems().addAll(Integer.toString(counter), "test1",
                    "test2");
            comboBox.setValue(Integer.toString(counter));

            comboboxes.add(comboBox);

            gridPane.add(comboboxes.get(counter - 1), j * 30, i * 35);
        }
    }

    Scene scene = new Scene(gridPane);
    primaryStage.setScene(scene);
    primaryStage.setWidth(1550);
    primaryStage.setHeight(670);
    primaryStage.show();

}   
}

您需要的可能是Timeline Animation。它允许您描述每帧的状态并延迟更改帧。
