Using command line arguments in Java with JavaFX
提问by Karatawi
I have the following code:
我有以下代码：
public class Main extends Application {
@Override
public void start(Stage primaryStage) throws Exception{
Parent root = FXMLLoader.load(getClass().getResource("hive.fxml"));
primaryStage.setTitle("Hive-viewer");
primaryStage.setScene(new Scene(root, 1600, 900));
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}
I want to know how you would use a file (given with the command line) in the Controller or in a method in the Main class
我想知道您将如何在 Controller 或 Main 类的方法中使用文件（通过命令行提供）
回答by Clayn
Try getParameters. This should give you the command line arguments
尝试getParameters。这应该给你命令行参数
As wished a small example (i took the main code from Raphael's answer)
正如希望的一个小例子（我从拉斐尔的回答中获取了主要代码）
Assuming the controller class is named "MyController"
假设控制器类被命名为“MyController”
public class Main extends Application {
@Override
public void start(Stage primaryStage) throws Exception{
FXMLLoader loader=new FXMLLoader(getClass().getResource("hive.fxml"));
Parent root = loader.load();
MyController cont=load.getController();
/*
This depends on your controller and you have to decide
How your controller need the arguments
*/
cont.setParameter(getParameters());
primaryStage.setTitle("Hive-viewer");
primaryStage.setScene(new Scene(root, 1600, 900));
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}
