重新想象 Windows 8 Store Apps (3) - 控件之內容控件: ToolTip, Frame, AppBar, ContentControl, ContentPresenter; 容器控件: Border, Viewbox, Popup

作者：webabcd


介紹
重新想象 Windows 8 Store Apps 之內容控件

• ToolTip - 提示框控件
• Frame - 框架控件，用於導航內容
• AppBar - 應用程序欄控件
• ContentControl ContentPresenter - ContentPresenter 用來呈現 ContentControl 的 Content

重新想象 Windows 8 Store Apps 之容器控件

• Border - 邊框控件
• Viewbox - 控制子元素如何拉伸的容器控件
• Popup - 彈出框控件

示例
1、ToolTip 的 Demo
