参考答案

参考解析
解析: 这个还是布局管理器的问题,流布局管理器(FlowLayout)将根据框架的大小随时调整它里面的组件的大小,包括高度和宽度,这个管理器不会约束组件的大小,而是允许他们获得自己的最佳大小,一行满了以后将在下一行放置组件;卡片管理器(CardLayout)一次显式一个加入的组件(根据加入时的关键字);网格管理器(GridLayout)将容器划分为固定的网格,容器大小的改变将影响所有组件的大小,每个组件的大小都会同等地变化;边界管理器(BorderLayout)将容器划分为五个区域,分为东南西北和中间,东西区域的宽度为该区域里面组件的最佳宽度,高度为容器的高度减去南北区域的高度,这是一个可能变化的值,而南北区域的宽度为容器的整个宽度,高度为组件的最佳高度,中间区域的高度为容器的高度减去南北区域的高度,宽度为容器的宽度减去东西区域的宽度。

考题 You use Microsoft .NET Framework 4 to create a Windows Presentation Foundation (WPF) application. You create a Button control for the application. You need to ensure that the application meets the following requirements: When the mouse pointer is over the Button control, the background color of the button is set to red and the Button control appears bigger. When the mouse pointer is not over the Button control, the button returns to its original state. What should you do?()A、Create a template. Declare a VisualState element in the template.B、Create a StoryBoard animation. Add an EventTrigger class to the Button control that begins the StoryBoard animation.C、Create a ScaleTransform class. Bind the ScaleX and ScaleY properties of the Button control to the Background property by using a custom value converter.D、Add a method named ChangeAppearance in the code-behind file. Subscribe the ChangeAppearance method to the MouseEnter event of the Button control.
