我在页面顶部有2个按钮，用于在登录和注册之间导航。 问题是：我无法在登录容器上聚焦（输入文本或按下按钮）（但是注册容器运行良好）。
请让我知道如何解决这个问题
答案 0 :(得分：2)
如果我把它放在IDE中，我会马上得到
组件'Page'的默认属性不接受多个对象。
所以，在你的两个容器周围放一个Container，这样Page里面只有一个元素。
import bb.cascades 1.0
Page {
Container {
// Login container
Container {
// Email
TextField {
}
// Password
TextField {
}
// Button login
Button {
}
}
// Register container
Container {
// Email
TextField {
}
// Password
TextField {
}
// Button register
Button {
}
}
}
}
编辑：
由于您添加了完整代码，因此存在另一个问题。您创建了登录容器，然后创建了“ScrollView”，用于注册新用户。问题ScrollView是在登录容器的顶部创建的，即使它不可见，也会在下面阻塞容器。两种解决方案：
