WPF利用WindowChrome实现自定义窗口
作者:黑夜中的潜行者 时间:2021-06-08 07:33:55
简介
Microsoft官网关于 WindowChome 的介绍
截取Microsoft文章的一段话:
若要在保留其标准功能时自定义窗口,可以使用该 WindowChrome 类。 该 WindowChrome 类将窗口框架的功能与视觉对象分开,并允许你控制应用程序窗口的客户端和非客户端区域之间的边界。 通过 WindowChrome 该类,可以通过扩展工作区来覆盖非工作区,将 WPF 内容置于窗口框架中。 同时,它通过两个不可见区域保留系统行为: 调整边框 和 标题 区域的大小。

布局实现
首先我们需要在 MainWindow 也就是我们的主窗口中的 Window.Resources 中实现 WindowChrome 的基本样式:
WindowChrome.ResizeBorderThickness 设置不可见边框宽度
WindowChrome.CaptionHeight> 设置属于标题栏的范围——高度
WindowChrome.UseAeroCaptionButtons 是否启用默认系统按钮功能——三大金刚键
WindowChrome.NonClientFrameEdges 设置客户区域,使用 bottom 可以实现加载时空白窗口而不显示默认窗口,提升用户体验
<Window
x:Class="SignalRClient.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:local="clr-namespace:SignalRClient"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
Title=""
Width="880"
Height="620"
MinWidth="700"
MinHeight="500"
Style="{StaticResource mainWindow}"
WindowChrome.WindowChrome="{DynamicResource WindowChromeKey}"
WindowStartupLocation="CenterScreen"
mc:Ignorable="d">
<Window.Resources>
<WindowChrome x:Key="WindowChromeKey">
<WindowChrome.ResizeBorderThickness>
<Thickness>5</Thickness>
</WindowChrome.ResizeBorderThickness>
<WindowChrome.CaptionHeight>60</WindowChrome.CaptionHeight>
<WindowChrome.UseAeroCaptionButtons>false</WindowChrome.UseAeroCaptionButtons>
<WindowChrome.NonClientFrameEdges>bottom</WindowChrome.NonClientFrameEdges>
</WindowChrome>
</Window.Resources>
</Window>
重写窗口,实现最大化窗口下,标题栏及客户区域偏移问题的修正。
通过代码获取当前窗口的工作区域,及任务栏以外的其他区域
System.Windows.SystemParameters.WorkArea.Width 获取工作区域的宽
System.Windows.SystemParameters.WorkArea.Height 获取工作区域的高
为什么要使用 ValueConverter 主要是因为 WorkArea 返回的类型无法直接 binding xaml
<ValueConverters:WorkAreaWidth x:Key="workAreaWidth" />
<ValueConverters:WorkAreaHeight x:Key="workAreaHeight" />
<Style x:Key="mainWindow" TargetType="{x:Type Window}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Window">
<ContentControl x:Name="window" Content="{TemplateBinding Content}" />
<ControlTemplate.Triggers>
<Trigger Property="WindowState" Value="Maximized">
<Setter TargetName="window" Property="MaxHeight" Value="{Binding Converter={StaticResource workAreaHeight}}" />
<Setter TargetName="window" Property="MaxWidth" Value="{Binding Converter={StaticResource workAreaWidth}}" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
using System;
using System.Globalization;
using System.Windows.Data;
namespace SignalRClient.ValueConverters
{
internal class WorkAreaWidth : IValueConverter
{
public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
{
return System.Windows.SystemParameters.WorkArea.Width;
}
public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
{
throw new NotImplementedException();
}
}
}
