如何加载的JavaFX initialize（）方法时在后台大文件？ [英] How to load big file in background during initialize() method of Javafx?

问题描述

应用程序的初始化过程中，我的JavaFX桌面应用负载和大的文本文件中的

My javafx desktop application load and big text file during the initialization of the application in the

 @Override
    public void initialize(URL url, ResourceBundle rb) {

      loadAppConfigurationFile();
   }


   private void loadAppConfigurationFile() {

        Task<Void> task = new Task<Void>() {
            @Override
            public Void call() throws InterruptedException {

                //read file and do some operation
                return null;
            }
        };
        new Thread(task).start();
    }

但这里的问题是我的应用程序界面没有出现，直到这个过程过来。我调用这个文件中读取另一个线程，不同的是我的GUI阶段/场景将被加载第一，他们直到该文件是在系统加载我可以显示一些加载消息。

But the problem here is my application GUI doesn't appear till this process it over. I invoked this file reading in another thread excepting that my GUI stage/scene will be loaded first and their I can show some loading message till that file is loaded in the system.

请告知确切的解决方法此。

Kindly tell the exact workaround for this.

推荐答案

我尝试这一点，它的工作很容易......这里的酒吧是一个进度条

i try this and its work easily...here bar is a progress bar

@FXML
void initialize() {
    assert bar != null : "fx:id=\"bar\" was not injected: check your FXML file 'Check.fxml'.";
    loadAppConfigurationFile();
}

private void loadAppConfigurationFile() {
    Task task = new Task<Void>() {
@Override public Void call() throws InterruptedException {
     int max = 1000000;
    for (int i=1; i<=max; i=i+10) {
        if (isCancelled()) {
           break;
        }
        updateProgress(i, max);
        System.out.println("somethings is here");
    }
    return null;
}
};
bar.progressProperty().bind(task.progressProperty());
new Thread(task).start();
}
