今天我要使用 JavaFX Fxml 项目创建 Hello World 应用程序。这里是代码。示例.fxml
<?xml version="1.0" encoding="UTF-8"?>
<?import java.lang.*?>
<?import javafx.scene.*?>
<?import javafx.scene.control.*?>
<?import javafx.scene.layout.*?>
<AnchorPane id="AnchorPane" prefHeight="200" prefWidth="320" xmlns:fx="http://javafx.com/fxml" fx:controller="temp.Temp">
<children>
<Button id="button" layoutX="126" layoutY="90" text="Click Me!" onAction="#handleButtonAction" fx:id="button" />
<Label id="label" layoutX="126" layoutY="120" minHeight="16" minWidth="69" prefHeight="16" prefWidth="69" fx:id="label" />
</children>
</AnchorPane>
示例.java
package temp;
import java.net.URL;
import java.util.ResourceBundle;
import javafx.event.ActionEvent;
import javafx.fxml.FXML;
import javafx.fxml.Initializable;
import javafx.scene.control.Label;
public class Sample implements Initializable {
@FXML
private Label label;
@FXML
private void handleButtonAction(ActionEvent event) {
System.out.println("You clicked me!");
label.setText("Hello World!");
}
@Override
public void initialize(URL url, ResourceBundle rb) {
// TODO
}
}
Temp.java
package temp;
import javafx.application.Appl
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;
public class Temp extends Application {
public static void main(String[] args) {
Application.launch(Temp.class, args);
}
@Override
public void start(Stage stage) throws Exception {
try{
Parent root = FXMLLoader.load(getClass().getResource("Sample.fxml"));
stage.setScene(new Scene(root));
stage.show();
}
catch(Exception e){
System.out.print(e);
}
}
}
但它给出错误/Users/apple/NetBeansProjects/Temp/nbproject/jfx-impl.xml:1757:执行此行时发生以下错误:/Users/apple/NetBeansProjects/Temp/nbproject/jfx-impl.xml: 1392:jarsigner 返回:1 BUILD FAILED(总时间:६ 秒)
但是当我使用异常处理时,它会给出未找到的位置?请帮忙
