[英]JavaFX main fxml not loading fxml

問題描述

我的應用程序具有選項卡式窗格，因此為了使fxml文件易於管理，我有一個主要的fxml文件，其中包含這些選項卡，以及每個其他選項卡的單獨fxml。 一切正常，但由於某種原因，該應用程序已停止加載第二個選項卡。 我嘗試將其單獨加載到主應用中，效果很好。 我嘗試創建一個新的fxml文件作為測試並加載它，這也可以正常工作。 但是，它不會將其加載到第二個選項卡中。 同樣，沒有輸出到控制台。

編輯：經過更多試驗后，我將其范圍縮小到了拆分窗格。 我嘗試了一個帶有按鈕的非常簡單的fxml，這很好，但是添加了一個拆分窗格和兩個按鈕，並且視圖不呈現。

這是我的主要課程：公共課程主要擴展應用{ 

@Override
public void start(Stage primaryStage) {

    Parent mainView;
    try {
        mainView = FXMLLoader.load(getClass().getResource("view/MainView.fxml"));
        Scene scene = new Scene(mainView);
        primaryStage.setTitle("Horse Show Manager");
        primaryStage.setScene(scene);
        primaryStage.show();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}
public static void main(String[] args) {
    launch(args);
}
}

這是我的mainview.fxml 

<?import javafx.geometry.*?>
<?import javafx.scene.control.*?>
<?import java.lang.*?>
<?import javafx.scene.layout.*?>
<?import javafx.scene.layout.GridPane?>


<TabPane maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="800.0"
    prefWidth="800.0" tabClosingPolicy="UNAVAILABLE" xmlns:fx="http://javafx.com/fxml/1" xmlns="http://javafx.com/javafx/8">
    <tabs>
        <Tab text="Classes">

        </Tab>
        <Tab text="Riders">
            <fx:include source="RiderPane.fxml" fx:id="riderPaneContent" />
        </Tab>
    </tabs>
</TabPane>

這是第一個窗格

我認為回答我自己的問題可能是錯誤的形式...但是解決方案是使用fx：define和fx：include標記定義兩個選項卡。 然后可以加載fxml內容。 下面的例子。 

<TabPane maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="800.0"
    prefWidth="800.0" tabClosingPolicy="UNAVAILABLE" xmlns="http://javafx.com/javafx/8" xmlns:fx="http://javafx.com/fxml/1">
    <fx:define>
        <fx:include fx:id="groupPaneContent" source="GroupPane.fxml" />
        <fx:include fx:id="riderPaneContent" source="RiderPane.fxml" />
    </fx:define>
    <tabs>
        <Tab closable="false" text="Classes" content="$groupPaneContent" />
        <Tab closable="false" text="Riders" content="$riderPaneContent" />
    </tabs>
</TabPane>

編輯： FXML最初不能正確呈現。 我必須手動調整應用程序的大小，使其顯示出來。 如果您知道如何解決此問題，請發表評論
