JavaFX第一篇

一、点击按钮变更字样

import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Scene;
import javafx.scene.layout.BorderPane;
import javafx.stage.Stage;

public class HelloApplication extends Application {

	@Override
	public void start(Stage primaryStage) throws Exception {
		//这里的root从FXML文件中j加载进行初始化，这里的FXMLLoader类用于加载FXML文件
		BorderPane root = (BorderPane)FXMLLoader.load(getClass().getResource("MainPanel.fxml"));
		Scene scene = new Scene(root,500,500);
		primaryStage.setScene(scene);
		primaryStage.setTitle("Hello JavaFx");
		primaryStage.show();
	}
	
	public static void main(String[] args) {
		launch(args);
	}

}

import javafx.event.ActionEvent;
import javafx.fxml.FXML;
import javafx.scene.control.Button;

public class MainPaneController {
	
	//这里的Button对象有需要加@FXML注解，然后变量的名称为你刚才在FXML文件中声明的Button的ID属性
	@FXML
	private Button btnHello;
	
	@FXML
	protected void handleButtonAction(ActionEvent event) {
		btnHello.setText("HELLO WORLD,I AM JAVAFX");
	}
}
