WPF 自定义Metro Style窗体

为了使WPF程序在不同版本的操作系统上保持一致的显示效果，我们需要重写WPF控件样式。这篇博客将展示如何创建一个Metro Style的WPF窗体。

首先先看一下最终窗体的效果图，

通过截图我们可以看出来这个窗体由两部分组成，顶部为最小化和关闭按钮，其他区域为窗体的显示区域。请看下面的具体实现代码，

MetroWindow样式：

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                    xmlns:local="clr-namespace:MetroWindow.Resources.Styles">
    <!--最小化按钮样式-->
    <Style x:Key="WinMinBtnStyle" TargetType="Button">
        <Setter Property="SnapsToDevicePixels" Value="True"/>
        <Setter Property="OverridesDefaultStyle" Value="True"/>
        <Setter Property="Width" Value="25"/>
        <Setter Property="Height" Value="25"/>
        <Setter Property="VerticalAlignment" Value="Top"/>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="Button">
                    <Border x:Name="MainBorder" Background="Transparent">
                        <Grid>
                            <ContentPresenter Content="{TemplateBinding Content}" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
                        </Grid>
                    </Border>
                    <ControlTemplate.Triggers>
                        <Trigger Property="IsMouseOver" Value="True">
                            <Setter TargetName="MainBorder" Property="Background" Value="#33a58d"/>
                        </Trigger>
                    </ControlTemplate.Triggers>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

    <!--关闭按钮样式-->
    <Style x:Key="WinCloseBtnStyle" TargetType="Button">
        <Setter Property="SnapsToDevicePixels" Value="True"/>
        <Setter Property="OverridesDefaultStyle" Value="True"/>
        <Setter Property="Width" Value="25"/>
        <Setter Property="Height" Value="25"/>
        <Setter Property="VerticalAlignment" Value="Top"/>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="Button">
                    <Border x:Name="MainBorder" Background="Transparent">
                        <Grid>
                            <ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
                        </Grid>
                    </Border>
                    <ControlTemplate.Triggers>
                        <Trigger Property="IsMouseOver" Value="True">
                            <Setter TargetName="MainBorder" Property="Background" Value="#d44c45"/>
                        </Trigger>
                    </ControlTemplate.Triggers>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

    <!--窗体控件模板-->
    <ControlTemplate x:Key="MetroWindowTemplate" TargetType="{x:Type Window}">
        <Border BorderBrush="#2a927c" BorderThickness="1" Background="White">
            <Grid>
                <Grid.RowDefinitions>
                    <RowDefinition Height="30"/>
                    <RowDefinition Height="*"/>
                </Grid.RowDefinitions>

                <Grid Grid.Row="0" Background="#2a927c">
                    <Grid.ColumnDefinitions>
                        <ColumnDefinition Width="Auto"/>
                        <ColumnDefinition Width="*"/>
                        <ColumnDefinition Width="Auto"/>
                        <ColumnDefinition Width="Auto"/>
                    </Grid.ColumnDefinitions>

                    <TextBlock x:Name="WindowTitleTbl" Grid.Column="0" Text="" FontFamily="Microsoft YaHei" VerticalAlignment="Center"
                                       FontSize="12" FontWeight="Bold" Margin="10,0" Foreground="White"/>

                    <Button x:Name="MinWinButton" Grid.Column="2" Style="{StaticResource WinMinBtnStyle}"
                                        VerticalContentAlignment="Center"
                                        HorizontalContentAlignment="Center">
                        <Button.Content>
                            <StackPanel>
                                <Path Stroke="White" StrokeThickness="2" Data="M1,6 L18,6"/>
                            </StackPanel>
                        </Button.Content>
                    </Button>

                    <Button x:Name="CloseWinButton" Grid.Column="3" Style="{StaticResource WinCloseBtnStyle}" Margin="2,0,8,0"
                                        HorizontalContentAlignment="Center"
                                        VerticalContentAlignment="Center">
                        <Button.Content>
                            <StackPanel>
                                <Path Stroke="White" StrokeThickness="2" Data="M2,2 L16,16 M2,16 L16,2"/>
                            </StackPanel>
                        </Button.Content>
                    </Button>
                </Grid>

                <AdornerDecorator Grid.Row="1">
                    <ContentPresenter/>
                </AdornerDecorator>
            </Grid>
            <Border.Effect>
                <DropShadowEffect/>
            </Border.Effect>
        </Border>
    </ControlTemplate>

    <Style x:Key="MetroWindowStyle" TargetType="{x:Type Window}">
        <Setter Property="SnapsToDevicePixels" Value="True"/>
        <Setter Property="OverridesDefaultStyle" Value="True"/>
        <Setter Property="AllowsTransparency" Value="True"/>
        <Setter Property="Background" Value="Transparent"/>
        <Setter Property="WindowStyle" Value="None"/>
        <Setter Property="Template" Value="{StaticResource MetroWindowTemplate}"/>
    </Style>
</ResourceDictionary>

新建一个ModernWindow类，

C#

    public class ModernWindow : Window
    {
        private Button CloseButton;
        private Button MinButton;
        private TextBlock WindowTitleTbl;

        public ModernWindow()
        {
            this.Loaded += ModernWindow_Loaded;
        }

        private void ModernWindow_Loaded(object sender, RoutedEventArgs e)
        {
            // 查找窗体模板
            ControlTemplate metroWindowTemplate
                    = App.Current.Resources["MetroWindowTemplate"] as ControlTemplate;

            if (metroWindowTemplate != null)
            {
                CloseButton = metroWindowTemplate.FindName("CloseWinButton", this) as Button;
                MinButton = metroWindowTemplate.FindName("MinWinButton", this) as Button;

                CloseButton.Click += CloseButton_Click;
                MinButton.Click += MinButton_Click;

                WindowTitleTbl = metroWindowTemplate.FindName("WindowTitleTbl", this) as TextBlock;
            }
        }

        private void CloseButton_Click(object sender, System.Windows.RoutedEventArgs e)
        {
            Close();
        }

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

        /// <summary>
        /// 实现窗体移动
        /// </summary>
        /// <param name="e"></param>
        protected override void OnMouseLeftButtonDown(MouseButtonEventArgs e)
        {
            DragMove();

            base.OnMouseLeftButtonDown(e);
        }
    }

现在我们就完成了Metro Style窗体了，现在对其进行应用。请看MainWindow实现：
XAML:

<local:ModernWindow x:Class="MetroWindow.MainWindow"
        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:MetroWindow"
        Style="{StaticResource MetroWindowStyle}"
        mc:Ignorable="d"
        Title="MainWindow" Height="350" Width="525">
    <Grid>

    </Grid>
</local:ModernWindow>

C#：

    public partial class MainWindow : ModernWindow
    {
        public MainWindow()
        {
            InitializeComponent();
        }
    }

现在就完成了Metro Style窗体的制作。
自Win8发布以来，越来越多的桌面应用开始实现Metro样式。现在也有很多WPF MetroUI库，例如：http://mui.codeplex.com/。我们可以根据项目的实际情况选择现有的Metro UI/Control，当然也可以自己写。
