如何在佈局中添加Richfx

我一直在嘗試在anylayout中的javafx和fxml文件的main方法中添加InlineStyleTextArea和CodeArea。我收到一個線程錯誤。如果可能，請使用示例如何將這些組件添加到javafx佈局中？如果可能的話與教程鏈接。如何在佈局中添加Richfx

這是一個簡單的代碼

public class Main extends Application { 

@Override 

public void start(Stage primaryStage) { 
TextField myTextField = new TextField(); 
InlineCssTextArea TextArea = new InlineCssTextArea(); 

    HBox hbox = new HBox(); 
hbox.getChildren().add(myTextField); 
hbox.getChildren().add(TextArea); 
HBox.setHgrow(myTextField, Priority.ALWAYS); 
HBox.setHgrow(TextArea, Priority.ALWAYS); 

Scene scene = new Scene(hbox); 
primaryStage.setScene(scene); 
primaryStage.show();} 

public static void main(String[] args) { 
launch(args); 


}

}

它們只是控件的子類，因此您可以使用完全相同的方式添加其他控件。你能發佈你收到的堆棧跟蹤嗎？ –

應用程序啓動方法中的異常 java.lang.reflect.InvocationTargetException \t at sun.reflect.NativeMethodAccessorImpl.invoke0（Native Method） –

我可以只是一個簡單的gui代碼示例嗎？ –

從堆棧跟蹤，它看起來像Java運行時無法找到（至少在一個類）的ReactFX庫，這是RichTextFX的依賴關係。既然它找到了，它一定找到了InlineCssTextArea，所以必須安裝RichTextFX庫。

如果您正在使用某種依賴關係管理（例如Gradle或Maven），那麼該工具應該爲您管理所有依賴關係。

如果您手動管理依賴關係（即下載jar文件並將它們添加到類路徑中），則需要確保要麼下載所有依賴的jar文件，要麼使用"Fat jar file"。
