接上一篇的通用窗体模板，这个模板是重写窗体样式的自定义模板，与上篇不同的是它将窗体的一些基本功能全部清空（放大、缩小、关闭按钮，窗体双击放大缩小，窗体可拖拉大小，标题和logo等）。我们需要重写函数来实现这些功能。

首先是新建窗体文件window.xaml,为何不用资源字典文件呢？因为我们需要写函数所以需要cs文件，而窗体文件新建后会自动生成window.xaml.cs，只需将window标签修改为ResourceDictionary即可。

cs文件中修改：

然后开始写窗体样式，在xaml中添加：

<!-- 菜单按钮组模板 --><Style x:Key="WindowCenterMenuBtn" TargetType="Button"><Setter Property="Foreground" Value="White"></Setter><Setter Property="Opacity" Value="0.2"></Setter><Setter Property="Template"><Setter.Value><ControlTemplate TargetType="Button"><TextBlock FontSize="25" Text="{TemplateBinding Content}" HorizontalAlignment="Center" VerticalAlignment="Center"></TextBlock><ControlTemplate.Triggers><Trigger Property="IsMouseOver" Value="True"><Setter Property="Opacity" Value="1.0"></Setter></Trigger></ControlTemplate.Triggers></ControlTemplate></Setter.Value></Setter></Style><!-- 通用窗口模板-标题居中 --><ControlTemplate x:Key="WindowCenterTemplate" TargetType="Window"><Border x:Name="WindowCenterFrame" Margin="0" CornerRadius="0" BorderThickness="1" BorderBrush="DodgerBlue"  Background="#FFFFFF" MouseLeftButtonDown="CustomWindow_MouseLeftButtonDown" ><Border.Effect><DropShadowEffect BlurRadius="3" RenderingBias="Performance" ShadowDepth="0" Opacity="1"/></Border.Effect><Grid ><Grid.RowDefinitions><RowDefinition Height="30"></RowDefinition><RowDefinition Height="*"></RowDefinition></Grid.RowDefinitions><Border Grid.Row="0"><Border.Background><LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0" Opacity="0.6"><GradientStop Color="#FFFBFBFC" Offset="1"/><GradientStop Color="#FFF3F7FB" Offset="0.021"/></LinearGradientBrush></Border.Background><Grid MouseDown="CustomWindow_MouseDoubleDown"><Grid.ColumnDefinitions><ColumnDefinition Width="1*"/><ColumnDefinition Width="120"/></Grid.ColumnDefinitions><StackPanel Grid.Column="0" Orientation="Horizontal" VerticalAlignment="Bottom" HorizontalAlignment="Center" Margin="60,0,0,0"><Button   Width="22"  HorizontalAlignment="Center" Style="{StaticResource {x:Static ToolBar.ButtonStyleKey}}"WindowChrome.IsHitTestVisibleInChrome="True"  Command="{x:Static SystemCommands.ShowSystemMenuCommand}"CommandParameter="{Binding ElementName=_MainWindow}"><!-- Make sure there is a resource with name Icon in MainWindow --><Image  Source="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=Icon}"WindowChrome.IsHitTestVisibleInChrome="True"/></Button><TextBlock   VerticalAlignment="Center" Text="{Binding Title, RelativeSource={RelativeSource TemplatedParent}}"  FontSize="13"/></StackPanel><StackPanel Orientation="Horizontal" Grid.Column="1" HorizontalAlignment="Right" Margin="0,0,20,0" VerticalAlignment="Center"><Button x:Name="MinBtn" Height="20" Width="30" Content="-" Style="{StaticResource ResourceKey=WindowCenterMenuBtn}" Click="CustomWindowBtnMinimized_Click" /><Button x:Name="MaxBtn" Height="20" Width="30" Content="□" Style="{StaticResource ResourceKey=WindowCenterMenuBtn}" Click="CustomWindowBtnMaxNormal_Click" /><Button x:Name="CloseBtn" Height="20" Width="30" Content="×" Style="{StaticResource ResourceKey=WindowCenterMenuBtn}" Click="CustomWindowBtnClose_Click" /></StackPanel></Grid></Border><Grid Grid.Row="1"><AdornerDecorator><ContentPresenter></ContentPresenter></AdornerDecorator></Grid></Grid></Border></ControlTemplate><!-- 通用窗口样式-标题居中 --><Style x:Key="WindowCenterChrome" TargetType="Window"><Setter Property="AllowsTransparency" Value="True"></Setter><Setter Property="Background" Value="Transparent"></Setter><Setter Property="WindowStyle" Value="None"></Setter><Setter Property="ResizeMode" Value="NoResize"></Setter><Setter Property="Template" Value="{StaticResource WindowCenterTemplate}"></Setter></Style>

接下来是功能函数，在cs文件中添加代码，实现窗口的放大、缩小、关闭、双击放大缩小、鼠标拖动窗口等。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.InteropServices;
using System.Text;using System.Windows.Input;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Interop;
using System.Windows.Media;
using System.Windows.Shapes;
using System.Windows.Threading;namespace Resource.Styles.Base
{public partial class CustomWindow : ResourceDictionary{public class Tools{//双击事件定时器private static DispatcherTimer _timer;//是否单击过一次private static bool _isFirst;static Tools(){_timer = new DispatcherTimer();_timer.Interval = new TimeSpan(0, 0, 0, 0, 400);_timer.Tick += new EventHandler(_timer_Tick);}/// <summary>/// 判断是否双击/// </summary>/// <returns></returns>public static bool IsDoubleClick(){if (!_isFirst){_isFirst = true;_timer.Start();return false;}else{return true;}}//间隔时间private static void _timer_Tick(object sender, EventArgs e){_isFirst = false;_timer.Stop();}}// 拖动private void CustomWindow_MouseLeftButtonDown(object sender, MouseEventArgs e){Window win = (Window) ((FrameworkElement) sender).TemplatedParent;if (e.LeftButton == MouseButtonState.Pressed){win.DragMove();}}//双击放大缩小private void CustomWindow_MouseDoubleDown(object sender, MouseEventArgs e){Window win = (Window) ((FrameworkElement) sender).TemplatedParent;if (Tools.IsDoubleClick()){win.WindowState = win.WindowState == WindowState.Maximized? WindowState.Normal: WindowState.Maximized;}}// 关闭private void CustomWindowBtnClose_Click(object sender, RoutedEventArgs e){Window win = (Window) ((FrameworkElement) sender).TemplatedParent;//提示是否要关闭if (MessageBox.Show("确定要退出系统？", "提示", MessageBoxButton.YesNo, MessageBoxImage.Question) ==MessageBoxResult.Yes){System.Windows.Application.Current.Shutdown();}}// 最小化private void CustomWindowBtnMinimized_Click(object sender, RoutedEventArgs e){Window win = (Window) ((FrameworkElement) sender).TemplatedParent;win.WindowState = WindowState.Minimized;}// 最大化、还原private void CustomWindowBtnMaxNormal_Click(object sender, RoutedEventArgs e){Window win = (Window) ((FrameworkElement) sender).TemplatedParent;if (win.WindowState == WindowState.Maximized){win.WindowState = WindowState.Normal;}else{// 不覆盖任务栏win.MaxWidth = SystemParameters.WorkArea.Width;win.MaxHeight = SystemParameters.WorkArea.Height;win.WindowState = WindowState.Maximized;}}}
}

最后在你要应用自定义样式的window窗体中添加引用：

<Window x:Class="EGIS.Main.UI.OPWindow"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"Style="{DynamicResource WindowCenterChrome}" mc:Ignorable="d" WindowStartupLocation="CenterScreen"Loaded="OPWindow_Loaded" ><Window.Resources><ResourceDictionary><ResourceDictionary.MergedDictionaries><ResourceDictionary Source="pack://application:,,,/EGIS.Resource;component/Resource/Generic.xaml" /></ResourceDictionary.MergedDictionaries></ResourceDictionary></Window.Resources>

在这个窗体的cs文件中的OPWindow_Loaded函数中添加如下语句（实现页面加载全屏不遮挡任务栏）：

 private void OPWindow_Loaded(object sender, RoutedEventArgs e){try{//使页面全屏化但不遮挡任务栏this.MaxWidth = SystemParameters.WorkArea.Width;this.MaxHeight = SystemParameters.WorkArea.Height;this.WindowState = WindowState.Maximized;}catch (Exception ex){LogService.WriteExceptionLog(ex, "");}}

还有一个窗体事件为鼠标拖动改变窗口大小，这个查询了网上的一些方法，最终用下面的代码实现：

 #region 重写页面，鼠标左键拖动改变窗口大小#region 这一部分是四个边加上四个角public enum ResizeDirection{Left = 1,Right = 2,Top = 3,TopLeft = 4,TopRight = 5,Bottom = 6,BottomLeft = 7,BottomRight = 8,}#endregion#region 用于改变窗体大小[DllImport("user32.dll", CharSet = CharSet.Auto)]private static extern IntPtr SendMessage(IntPtr hWnd, uint Msg, IntPtr wParam, IntPtr lParam);private void ResizeWindow(ResizeDirection direction){SendMessage(hs.Handle, WM_SYSCOMMAND, (IntPtr)(61440 + direction), IntPtr.Zero);}#endregion#region 为元素注册事件private void InitializeEvent(){//获取当前窗口调用的style样式Style temStyle = this.Resources["CustomWindowChrome"] as Style;if (temStyle!=null){Setter temSetter = null;foreach (Setter item in temStyle.Setters){if (item.Value == Template)temSetter = item;}ControlTemplate baseWindowTemplate = (ControlTemplate)temSetter.Value;Border borderClip = (Border)baseWindowTemplate.FindName("CustomWindowFrame", this);borderClip.MouseMove += delegate{DisplayResizeCursor(null, null);};borderClip.PreviewMouseDown += delegate{Resize(null, null);};borderClip.MouseLeftButtonDown += delegate{DragMove();};this.PreviewMouseMove += delegate{ResetCursor(null, null);};}}#endregion#region 重写的DragMove，以便解决利用系统自带的DragMove出现Exception的情况public new void DragMove(){if (this.WindowState == WindowState.Normal){SendMessage(hs.Handle, WM_SYSCOMMAND, (IntPtr)0xf012, IntPtr.Zero);SendMessage(hs.Handle, WM_LBUTTONUP, IntPtr.Zero, IntPtr.Zero);}}#endregion#region 显示拖拉鼠标形状private void DisplayResizeCursor(object sender, MouseEventArgs e){Point pos = Mouse.GetPosition(this);double x = pos.X;double y = pos.Y;double w = this.ActualWidth;  //注意这个地方使用ActualWidth,才能够实时显示宽度变化double h = this.ActualHeight;if (x <= relativeClip & y <= relativeClip) // left top{this.Cursor = Cursors.SizeNWSE;}if (x >= w - relativeClip & y <= relativeClip) //right top{this.Cursor = Cursors.SizeNESW;}if (x >= w - relativeClip & y >= h - relativeClip) //bottom right{this.Cursor = Cursors.SizeNWSE;}if (x <= relativeClip & y >= h - relativeClip)  // bottom left{this.Cursor = Cursors.SizeNESW;}if ((x >= relativeClip & x <= w - relativeClip) & y <= relativeClip) //top{this.Cursor = Cursors.SizeNS;}if (x >= w - relativeClip & (y >= relativeClip & y <= h - relativeClip)) //right{this.Cursor = Cursors.SizeWE;}if ((x >= relativeClip & x <= w - relativeClip) & y > h - relativeClip) //bottom{this.Cursor = Cursors.SizeNS;}if (x <= relativeClip & (y <= h - relativeClip & y >= relativeClip)) //left{this.Cursor = Cursors.SizeWE;}}#endregion#region  还原鼠标形状private void ResetCursor(object sender, MouseEventArgs e){if (Mouse.LeftButton != MouseButtonState.Pressed){this.Cursor = Cursors.Arrow;}}#endregion#region 判断区域，改变窗体大小private void Resize(object sender, MouseButtonEventArgs e){Point pos = Mouse.GetPosition(this);double x = pos.X;double y = pos.Y;double w = this.ActualWidth;double h = this.ActualHeight;if (x <= relativeClip & y <= relativeClip) // left top{this.Cursor = Cursors.SizeNWSE;ResizeWindow(ResizeDirection.TopLeft);}if (x >= w - relativeClip & y <= relativeClip) //right top{this.Cursor = Cursors.SizeNESW;ResizeWindow(ResizeDirection.TopRight);}if (x >= w - relativeClip & y >= h - relativeClip) //bottom right{this.Cursor = Cursors.SizeNWSE;ResizeWindow(ResizeDirection.BottomRight);}if (x <= relativeClip & y >= h - relativeClip)  // bottom left{this.Cursor = Cursors.SizeNESW;ResizeWindow(ResizeDirection.BottomLeft);}if ((x >= relativeClip & x <= w - relativeClip) & y <= relativeClip) //top{this.Cursor = Cursors.SizeNS;ResizeWindow(ResizeDirection.Top);}if (x >= w - relativeClip & (y >= relativeClip & y <= h - relativeClip)) //right{this.Cursor = Cursors.SizeWE;ResizeWindow(ResizeDirection.Right);}if ((x >= relativeClip & x <= w - relativeClip) & y > h - relativeClip) //bottom{this.Cursor = Cursors.SizeNS;ResizeWindow(ResizeDirection.Bottom);}if (x <= relativeClip & (y <= h - relativeClip & y >= relativeClip)) //left{this.Cursor = Cursors.SizeWE;ResizeWindow(ResizeDirection.Left);}}#endregion#endregion

代码中注意修改一下，将CustomWindowChrome改为通用窗体的名称WindowCenterChrome。CustomWindowFrame修改为WindowCenterFrame。

到此，一个完全重写的自定义样式就完成了，还有一点和上篇的通用窗体样式一样，会与WindowsFormsHost控件有冲突。

注意代码中的标签或样式名称问题，可能会有没有统一的部分，使用时自己排查一下。
