前言：Javafxml 的新手 我的应用程序运行良好。我只有一个问题，我知道应该有一个非常简单的解决方案，但我想不出更多。

当我运行我的应用程序时，我得到一个空窗口。 空窗

我必须调整窗口大小以获得所需的

调整大小的窗口

@FXML
void invoice(ActionEvent event) throws IOException {
FXMLLoader loader = new FXMLLoader();
    loader.setLocation(getClass().getResource("/view/Invoice2.fxml"));
    Parent planner;
    try {
        planner = (Parent) loader.load();
        stage.setTitle("Order Details");
        stage.getScene().setRoot(planner);

    } catch (IOException e) {
        e.printStackTrace();
    }

}

经过几天的努力，我终于通过简单地将整个 fxml 的结构放在另一个 Anchor Pane 中来解决它。我不知道为什么会解决它或如何解决它，但是当我将整个 GUI 包装在 Anchor Pane 中时，它开始正常工作。

尝试以下操作：

try {
   Parent planner = FXMLLoader.load(getClass().getResource("/view/Invoice2.fxml"));

   stage.setTitle("Order Details");
   stage.setScene(new Scene(planner));
} catch (IOException e) {
   e.printStackTrace();
}

而不是stage.getScene().setRoot(planner)我用过stage.setScene(new Scene(planner));。

而不是loader.setLocation(getClass().getResource("/view/Invoice2.fxml"));将资源更改为"../view/Invoice2.fxml". 如果您的项目目录结构如下所示，这将起作用：

project
|
\_ view
|  |
|  \_ Invoice2.fxml
\_ main
   \_ Main.java

"../path"表示所选路径在同一个父目录中，而不是在我们当前目录中。
