Windows 8实用窍门系列：10.Windows 8的基本变换和矩阵变换以及AppBar应用程序栏

　　在Windows 8中有几种基本变换和矩阵变换和Silverlight中的使用方法都是一样。

　　包括：　RotateTransform:旋转变换

　　　　　　ScaleTransform：缩放变换

　　　　　　SkewTransform：倾斜变换

　　　　　　TranslateTransform：移动变换

　　　　　　TransformGroup：变换组

　　　　　　MatrixTransform：矩阵变换

　　这些变换的意义和使用都可以看我之前写过的两篇文章：

　　Silverlight实用窍门系列：53.Silverlight中的5种基本变换RotateTransform、ScaleTransform、SkewTransform、TranslateTransform、TransformGroup

　　Silverlight实用窍门系列：54.详解Silverlight中的矩阵变换MatrixTransform，实现其余各种变换

　　AppBar应用程序栏是在Windows 8程序在右击程序下方或者手指从下往上滑动弹出的一个消息栏。在这个栏里可以做一些自定义的操作如：卸载程序，添加信息，搜索等操作。

　　AppBar代码如下：

    <Page.BottomAppBar>
        <AppBar>
            <Grid Background="Green" HorizontalAlignment="Left" Width="1355">
                <Grid.ColumnDefinitions>
                    <ColumnDefinition Width="425*">
                    </ColumnDefinition>
                    <ColumnDefinition Width="248*"/>
                </Grid.ColumnDefinitions>
                <StackPanel Orientation="Horizontal" Grid.Column="0" HorizontalAlignment="Left">
                    <Button x:Name="appBarAdd"  Content="添加" Click="appBarAdd_Click"/>
                    <Button x:Name="appBarDelete"  Content="删除" Click="appBarDelete_Click"/>
                </StackPanel>
                <StackPanel Orientation="Horizontal" Grid.Column="1" HorizontalAlignment="Right">
                    <Button x:Name="AppBarMore" Content="更多" Click="AppBarMore_Click"/>
                </StackPanel>
            </Grid>
        </AppBar>
    </Page.BottomAppBar>

        private void appBarAdd_Click(object sender, RoutedEventArgs e)
        {
            this.tbText.Text = "点击了添加按钮！";
        }

        private void appBarDelete_Click(object sender, RoutedEventArgs e)
        {
            this.tbText.Text = "点击了删除按钮！";
        }

        private void AppBarMore_Click(object sender, RoutedEventArgs e)
        {
            this.tbText.Text = "点击了更多按钮！";
        }
