SimpleButton Not Displaying

Question

Я просто пытаюсь получить SimpleButton, чтобы появиться на сцене в проекте AS3. По какой-то причине он не появится. Может ли кто-нибудь понять, почему?

Заранее спасибо.

Вам нужно добавить созданный SimpleButton объект myButton в список отображения, в котором CustomButton «s:

// ... 
    var myButton:SimpleButton = new SimpleButton(btnUpState, btnOverState, btnDownState, btnOverState); 
    myButton.name = buttonText; 
    myButton.height = btnHeight; 
    myButton.width = btnWidth; 

    addChild(myButton); 
} 

Хотя в вашем случае, может быть, вы должны думать о том, чтобы CustomButton вместо этого просто замените SimpleButton.
