JavaFX: How to get stage from controller during initialization?

我的未来我决定 提交于 2019-11-26 16:03:04
I want to handle stage events (i.e. hiding) from my controller class. So all I have to do is to add a listener via ((Stage)myPane.getScene().getWindow()).setOn*whatIwant*(...); but the problem is that initialization starts right after Parent root = FXMLLoader.load(getClass().getResource("MyGui.fxml")); and before Scene scene = new Scene(root); stage.setScene(scene); thus .getScene() returns null. The only workaround I found by myself is to add a listener to myPane.sceneProperty(), and when it becomes not null I get scene, add to it's .windowProperty() my !goddamn! listener handling which I

JavaFX Application Icon

问题 Is it possible to change the application icon using JavaFX, or does it have to be done using Swing? 回答1: Assuming your stage is "stage" and the file is on the filesystem: stage.getIcons().add(new Image("file:icon.png")); As per the comment below, if it's wrapped in a containing jar you'll need to use the following approach instead: stage.getIcons().add(new Image(<yourclassname>.class.getResourceAsStream("icon.png"))); 回答2: I tried this and it totally works. The code is: stage.getIcons().add(

I have problem when trying to close current scene and open up another scene when menuItem is selected.

首先进入oracle官网下载文件 点击进入 点击之后,会跳转登录,没有账号就去注册一个很快的哈,然后等待下载... 下载好之后,新建一个文件夹,文件夹里面创建一个子文件夹 名称必须为 database 用于存放解压后的安装文件 如果不修改 database\stage\cvu\cvu_prereq.xml 文件,则双击 setup.exe 会运行出错 修改 database\stage\cvu\cvu_prereq.xml 配置文件 <OPERATING_SYSTEM RELEASE="6.2"> <VERSION VALUE="3"/> <ARCHITECTURE VALUE="64-bit"/> <NAME VALUE="Windows 10"/> <ENV_VAR_LIST> <ENV_VAR NAME="PATH" MAX_LENGTH="1023" /> </ENV_VAR_LIST> </OPERATING_SYSTEM> 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 来源: https://www.cnblogs.com/taopanfeng/p/11318795.html

Spark Application、Driver、Job、stage、task

1、Application   application(应用)其实就是用spark-submit提交的程序。一个application通常包含三部分:从数据源(比方说HDFS)取数据形成RDD,通过RDD的transformation和action进行计算,将结果输出到console或者外部存储。 2、Driver   Spark中的driver感觉其实和yarn中Application Master的功能相类似。主要完成任务的调度以及和executor和cluster manager进行协调。有client和cluster联众模式。client模式driver在任务提交的机器上运行,而cluster模式会随机选择机器中的一台机器启动driver。通俗讲,driver可以理解为用户自己编写的程序。我们使用spark-submit提交一个Spark作业之后,这个作业就会启动一个对应的Driver进程.   Driver进程本身会根据我们设置的参数,占有一定数量的内存和CPU core。而Driver进程要做的第一件事情,就是向集群管理器(常用的如 yarn)申请运行Spark作业需要使用的资源,这里的资源指的就是Executor进程。YARN集群管理器会根据我们为Spark作业设置的资源参数,在各个工作节点上,启动一定数量的Executor进程

Here is the code that matters. I have an INT variable wich must take the value of a function: codigo = controller
