JavaFX将ActionListener添加到按钮 [英] Javafx adding ActionListener to button

问题描述

button.setOnAction(new EventHandler<ActionEvent>() {
    @Override public void handle(ActionEvent e) {
        label.setText("Accepted");
    }
});

在上面的代码中，我们定义了按下按钮时将发生的情况.一切都很好，但是我想创建新的ActionListener，然后将其添加到我的按钮中. 通常，在JButton中，我可以像这样添加ActionListener:

In the code above we are defining what will happen when we press the button. This is all good but I wanna create new ActionListener and then add it to my button. Normally in JButton I can just add ActionListener like this:

button.addActionListener(someControllerClass.createButtonListener());

在上面的代码中，createButtonListener()返回ActionListener.

In code above createButtonListener() returns ActionListener.

我的问题是:JButton addActionListener等效于什么?

My question is: What is the equivalent of JButton addActionListener ?

推荐答案

我认为这是我应该做的.创建处理程序:

I think this is how I should do. Creating the handler:

public EventHandler<Event> createSolButtonHandler()
{
    btnSolHandler = new EventHandler<Event>() {

        @Override
        public void handle(Event event) {
            System.out.println("Pressed!");
            biddingHelperFrame.getBtnSag().setVisible(false);
        }
    };
    return btnSolHandler;
}

将处理程序添加到按钮:

Adding Handler to button:

btnSol.addEventHandler(MouseEvent.MOUSE_CLICKED, biddingHelperFrameController.createSolButtonHandler());
