9.ウィンドウのカスタムルックを[WPFに学びます]

基本的な考え方は、オリジナルのWindowStyleがNoneに設定され、その後、自分自身にタイトルバーを取得

A、のXmaI

<Window x:Class="YKCore.WindowSetup" Name="WinMain"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:local="clr-namespace:YKCore"
        mc:Ignorable="d"
        WindowState="Maximized"
        WindowStyle="None" SizeChanged="WinMain_SizeChanged"
        Height="450" Width="800" BorderThickness="0" Background="{DynamicResource BackgroundColor}"
    xmlns:theme="clr-namespace:Microsoft.Windows.Themes;assembly=PresentationFramework.Aero2">
   
        <!-- 最大化按钮形状 -->
        <PathGeometry x:Key="pathMaximize">
            <PathGeometry.Figures>
                M1,1  L1 ,11 L11,11 L11,1 z M0,0 L12,0 L12,12 L0,12 z
            </PathGeometry.Figures>
        </PathGeometry>
        <!-- 还原按钮形状 -->
        <PathGeometry x:Key="pathRestore">
            <PathGeometry.Figures>
                M1,3 L1,11 L9,11 L9,3 z M3,1 L3,2 L10,2 L10,9 L11,9 L11,1 z M2 ,0 L12,0 L12,10 L10,10 L10,12 L0,12 L0,2 L2 ,2 z
            </PathGeometry.Figures>
        </PathGeometry>

    </Window.Resources>
    <Grid>
        <Grid.RowDefinitions>
            <RowDefinition Height="50"></RowDefinition>
            <RowDefinition Height="*"></RowDefinition>
        </Grid.RowDefinitions>
        <Border BorderBrush="{DynamicResource ForeColor}" BorderThickness="2,2,2,0" Padding="10,0">
            <Grid>
<!--自己画个图标，也就是一个圆角矩形里面写了个字母M-->
                <Rectangle Width="30" Height="28" Stroke="Yellow" StrokeThickness="1" HorizontalAlignment="Left" RadiusX="5" RadiusY="5" />
                <TextBlock Text="M" Foreground="Yellow" Margin="10,0,0,0">
                    <TextBlock.RenderTransform>
                        <SkewTransform AngleX="-15"/>
                    </TextBlock.RenderTransform>
                </TextBlock>


                <StackPanel Orientation="Horizontal" VerticalAlignment="Center" HorizontalAlignment="Right">

                    <Button x:Name="BtnMin"  Width="28" Height="28"   Click="BtnMin_Click" >
                        <Path  Data="M0,5 L12,5 L12,6 L0,6 z" Fill="{DynamicResource ForeColor}" Width="12" Height="12"/>
                    </Button>
                    <Button x:Name="BtnMax"  Width="28" Height="28"  Click="BtnMax_Click">
                        <Path x:Name="PMax" Fill="{DynamicResource ForeColor}" Width="12" Height="12"/>
                    </Button>
                    <Button x:Name="BtnClose"  Width="28" Height="28"  Click="BtnClose_Click" >
                        <Button.Content>
                            <Path Data="M1,0 L6,5 L11,0 L12,1 L7,6 L12,11 L11,12 L6,7 L1,12 L0,11 L5,6 L0,1 z" Fill="{DynamicResource ForeColor}" Width="12" Height="12"/>
                        </Button.Content>
                    </Button>
                </StackPanel>
            </Grid>
        </Border>
        <Border Grid.Row="1" BorderBrush="{DynamicResource ForeColor}" BorderThickness="2" Padding="10">
<!--原来的Window的Content-->
        </Border>
    </Grid>
</Window>

第二に、コードビハインド（いくつかのイベント）

        private void BtnClose_Click(object sender, RoutedEventArgs e)
        {
            Application.Current.Shutdown();
        }

        private void BtnMax_Click(object sender, RoutedEventArgs e)
        {
            this.WindowState = this.WindowState != WindowState.Maximized ? WindowState.Maximized : WindowState.Normal;
        }

        private void BtnMin_Click(object sender, RoutedEventArgs e)
        {
            this.WindowState = WindowState.Minimized;
        }

        private void WinMain_SizeChanged(object sender, SizeChangedEventArgs e)
        {
            PMax.Data = this.WindowState == WindowState.Maximized ? Resources["pathRestore"] as Geometry : Resources["pathMaximize"] as Geometry;
        }
