我的按钮无法打开我的课程

Question

Basically, the problem is I created an interface with Java Scene Builder. And from FXML button I wanted to open my class.

    @FXML
    public void pressButton(ActionEvent event) throws Exception {
    Platform.runLater(() -> {
        try{
            new SerialChart().start(new Stage());
        } catch (Exception e) {
            e.printStackTrace();
        }
    });

    }

    @FXML
    public void pressButton2(ActionEvent event) throws Exception {                      
    Platform.runLater(() -> {
         try {
            new Main().start(new Stage());
        } catch (Exception e) {
            e.printStackTrace();
        }
    });
    }

And my Main can be open, but my SerialChart can't be opened. It says "The constructor SerialChart() is undefined". So here is the problem I think

    public SerialChart(String title) {  
    super(title);

I think this is the problem why I can't open. Please help me... I can show you the whole code if you need.

Answer 1

Like Jim Garrisson said, your constructor that you call takes no arguments, but your defined one does (String title). This means you need to pass in a String argument (Even a blank one like "" will work) when you call it in the Button function.

new SerialChart("Some Title").start(new Stage()); //should be your call in the Button function.

Answer 2

so this is the answer I figured out SO HAPPY

    public void pressButton(ActionEvent event) throws Exception {
    Platform.runLater(() -> {
        try{
            SerialChart serialChartDemo = new SerialChart("Clean Energy Data Real time graph");
            serialChartDemo.pack();  
            RefineryUtilities.centerFrameOnScreen(serialChartDemo);  
            serialChartDemo.setVisible(true);
        } catch (Exception e) {
            e.printStackTrace();
        }
    });

}
