如何判断javafx.scene.media.MediaPlayer是否正在播放？最好不要对构建路径进行任何外部导入或添加.如果这是不可能的,那么我可以使用任何自包含的库吗？我正在ARM CPU上安装此软件,所以我试图使这段代码尽可能简约.我只会使用这个框架播放音乐文件,主要是MP3.有关如何判断玩家是否正在使用此库或其他库播放音乐的任何建议？

我已经创建了一个Java/JavaFX控制台,现在我面临一个例外:Console reports an Internal error.The error is: java.lang.IllegalStateException: Not on FX application thread; currentThread = Thread-5.控制台的代码:

package core.console;
import javafx.concurrent.Service;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.scene.control.TextArea;
import javafx.stage.Stage;

import java.io.*;
import java.util.ResourceBundle;

public class Console implements Runnable{
    private Console(ResourceBundle resourceBundle) throws IOException {
        FXMLLoader loader = new FXMLLoader(this.getClass().getResource("Console.fxml"), resourceBundle);
        Parent root = (Parent) loader.load();
        controller = loader.getController();
        Scene scene = new Scene(root);
        stage = new Stage();
        stage.setScene(scene);
        textArea = controller.getTextArea();
        show();

        PipedOutputStream pout=new PipedOutputStream(this.pin);
        System.setOut(new PrintStream(pout,true)); …

所以我当然直接创建一个简单的例子.

public class Main extends Application {

URL bla = getClass().getResource("/sample.fxml");

@Override
public void start(Stage primaryStage) throws Exception{
    //If you get weird errors: http://zenjava.com/javafx/maven/fix-classpath.html
        //but not actually my issue. Example displays fine in intellij.

    try {

        FXMLLoader loader = new FXMLLoader(bla);
        Parent root = loader.load(bla);

        primaryStage.setTitle("Hello World");
        primaryStage.setScene(new Scene(root));
        primaryStage.show();

        Controller controller = loader.<Controller>getController() ;
        assert(controller != null);
        controller.getLabel().setText("Kaboom!");
    } catch (Exception e) {
        // Exception gets thrown if the fxml file could not be loaded
        e.printStackTrace();
    }
}

几天前我刚刚介绍了JavaFX和Scene Builder,所以我在这里学习基础知识.我有最新版本的JavaFX,并使用Scene Builder来促进动作事件.此外,任何指向相关教程的指针都会有所帮助.在当天的某个时刻,我专注于Scene Builder编码面板的键盘部分,特别是"On Key Released"事件没有结果.提前致谢

这是我想要做的一个粗略的想法:

@FXML
Text Field theTextField;

@FXML
Button theButton;

@FXML  
void ButtonPressed() {
    //do stuff here
}

@FXML
//when ENTER is pressed the button is activated
void textFieldEnterPressed() {
    ButtonPressed();
}

我需要绑定主控制器中不同fxml的控件.我有3个名为MainView.fxml,ChildView1.fxml和ChildView2.fxml的fxml文件.

MainView.fxml

<AnchorPane fx:id="view" prefHeight="280.0" prefWidth="500.0" xmlns:fx="http://javafx.com/fxml/1" xmlns="http://javafx.com/javafx/2.2" fx:controller="binding.example2.MainViewController">
<children>
<VBox prefHeight="280.0" prefWidth="500.0" AnchorPane.bottomAnchor="0.0" AnchorPane.leftAnchor="0.0" AnchorPane.rightAnchor="0.0" AnchorPane.topAnchor="0.0">
  <children>
    <fx:include fx:id="child1" source="ChildView1.fxml" />
    <fx:include fx:id="child2" source="ChildView2.fxml" />
  </children>
</VBox>
</children>
</AnchorPane>

ChildView1.fxml

<AnchorPane fx:id="view" prefHeight="78.0" prefWidth="464.0" xmlns:fx="http://javafx.com/fxml/1" xmlns="http://javafx.com/javafx/2.2" fx:controller="binding.example2.ChildView1Controller">
<children>
<HBox layoutX="32.0" layoutY="14.0" prefHeight="51.0" prefWidth="200.0" spacing="10.0">
 <children>
    <Button fx:id="button1" mnemonicParsing="false" prefHeight="37.0" text="Button1" />
    <Button fx:id="button2" mnemonicParsing="false" prefHeight="37.0" text="Button2" />
  </children>
</HBox>
</children>
</AnchorPane>

ChildView2.fxml

<AnchorPane fx:id="view" prefHeight="244.0" prefWidth="568.0" xmlns:fx="http://javafx.com/fxml/1" xmlns="http://javafx.com/javafx/2.2" fx:controller="binding.example2.ChildView2Controller">
 <children>
   <TableView fx:id="tableView" prefHeight="244.0" prefWidth="568.0" AnchorPane.bottomAnchor="0.0" AnchorPane.leftAnchor="0.0" AnchorPane.rightAnchor="0.0" AnchorPane.topAnchor="0.0" /> …

我有一个班级,如:

public class myClass{

int age;
String name;

public String toString(){
return name;

};
}

public static ObservableList<myClass> myClassList;

我想知道是否有可能

ChoiceBox<myClass> choiceChart = new ChoiceBox<>(myClassList);

谢谢

PS我想有类似的情况

使用JavaFX 2渲染POJO

但使用ChoiceBox

编辑:

这是我的情况:我有一个tableView,在其中一个列中我必须使用toString()方法从myClass类型的对象设置一个String.

我试过用这些方法(其中myClass - > CustomInternalWindow类)

public static class Indicators{
      private final SimpleStringProperty tool_col;
      private final SimpleStringProperty chart_col;
      private final SimpleStringProperty pane_col;
      private final SimpleBooleanProperty on_col;

      private Indicators(String tl, CustomInternalWindow chrt, String pne, Boolean sel){
          this.tool_col = new SimpleStringProperty (tl);
          if (chrt == null) {
              this.chart_col = null;                  
          }
          else …

我在申请中面临一个奇怪的问题.

我想在两个不同的选项卡上复制UI(即两个不同的选项卡将在其容器中保存相同的VBox对象).

我期待的是,而不是创建两个不同的VBox对象添加到Tab1和Tab2我将创建一个单独的VBox对象,填充所需的内容,然后将相同的对象添加到Tab1和Tab2.

目前正在发生的事情是如果我将该UI添加到Tab1然后它才能正确显示.但是如果我向Tab2添加相同的对象,那么它将从Tab1中消失.

下面是我正在使用的示例代码.

@FXML
private Tab tab1, tab2;

Label label=new Label("Sample");

tab1.setContent(label);
tab2.setContent(label);

我在这两个标签内容中的假设是什么,我将看到示例文本.

但是示例文本仅显示在Tab2而不是Tab1中.(Tab1显示为空.)

我是Javafx的新手,所以如果我问一个愚蠢的问题,请耐心等待:)

嗨,IllegalArgumentException当我点击任何控件或场景的空白区域时,我得到了.下面是堆栈跟踪.我不能为每个控件编写一个方法MouseEvent.当我点击场景中的空白区域或禁用的控件时,你能否建议一个解决方案来取消这个鼠标事件.

尽管在设置文本之前设置了id，但事件处理程序之前的代码中的Text对象并没有改变颜色。但是，文本将随着文本设置的填充而改变颜色。我很好奇的一件事是，在CSS中，颜色不会随着.text{}OR 改变#Sign-In-Text{}。我只是不正确地使用CSS吗？

Java代码：

public class CSSTrial1 extends Application {

@Override
public void start(Stage stage) throws Exception {
    stage.setTitle("CSS Trial");
    stage.setResizable(false);
    final GridPane grid = new GridPane();
    ColumnConstraints constraints = new ColumnConstraints();
    grid.getColumnConstraints().add(constraints);
    grid.setAlignment(Pos.CENTER);
    grid.setHgap(10);
    grid.setVgap(10);
    grid.setPadding(new Insets(25));
    grid.add(new Label("Character Name:"), 0, 0);
    final TextField nameField = new TextField("");
    nameField.setPromptText("Randel James");
    grid.add(nameField, 1, 0);
    grid.add(new Label("Weapon:"), 0, 1);
    final ComboBox<String> weapons = new ComboBox<>();
    weapons.getItems().addAll("Katsuragi x2", "Assault Rifle",
            "Pistol", "RPG-7", "Barret 50. Cal");
    grid.add(weapons, 1, 1);
