JavaFX通過“點擊”加載新窗口

Preface

方法：初始的stage方法一樣，沒有任何的區別

此處，爲了部分（偷懶的）同學方便，給出實例，實則非常簡單。

核心的內容是在Controller.java中

    @FXML
    private void newButtonOnClicked(){
        try {
            //一定需要使用try-catch，不然編譯器不會讓你過的，Trust me!
            Parent anotherRoot = FXMLLoader.load(getClass().getResource("sample.fxml"));
            Stage anotherStage = new Stage();
            anotherStage.setTitle("Another Window Triggered by Clicking");
            anotherStage.setScene(new Scene(anotherRoot, 600, 329));
            anotherStage.show();
        } catch (Exception e){
            e.printStackTrace();
        }
    }

        try {
            //一定需要使用try-catch
            //下段實現的內容和Main.java中其實是一樣的
            Parent anotherRoot = FXMLLoader.load(getClass().getResource("sample.fxml"));
            Stage anotherStage = new Stage();
            anotherStage.setTitle("Another Window Triggered by Clicking");
            anotherStage.setScene(new Scene(anotherRoot, 600, 329));
            anotherStage.show();
