WPF 去边框 自定义窗体 拖动窗体大小变化

wpf 自定义窗体 并 拖动窗体大小变化 网上普遍 实现都是 win32那一套或者用windowChrome.Shell这两种方式。实际上wpf目前已经集成了windowChrome。那么新的使用方式怎么弄呢？非常简单！

Xaml实现代码

后台都不用写任何代码哟！

<Window x:Class="TestNoBorderWindow"        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"        Title="TestNoBorderWindow"        Width="300"        Height="300"        MinWidth="100"        MinHeight="100"        mc:Ignorable="d">    <Window.Style>        <Style TargetType="Window">            <Setter Property="Background" Value="Transparent" />            <Setter Property="WindowStyle" Value="None" />            <Setter Property="ResizeMode" Value="CanResize" />            <Setter Property="AllowsTransparency" Value="True" />            <Setter Property="WindowChrome.WindowChrome">                <Setter.Value>                    <WindowChrome CaptionHeight="30" ResizeBorderThickness="20" />                </Setter.Value>            </Setter>        </Style>    </Window.Style>    <Border Margin="10"            Background="White"            BorderBrush="Red"            BorderThickness="1"            CornerRadius="5"            SnapsToDevicePixels="True">        <Border.Effect>            <DropShadowEffect BlurRadius="10"                              Direction="0"                              ShadowDepth="0" />        </Border.Effect>        <Grid />    </Border></Window>

当然你也可以直接写成Window的Style

<Window x:Class="TestNoBorderWindow"        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"        Title="TestNoBorderWindow"        Width="300"        Height="300"        MinWidth="100"        MinHeight="100"        mc:Ignorable="d">    <Window.Style>        <Style TargetType="Window">            <Setter Property="Background" Value="Transparent" />            <Setter Property="WindowStyle" Value="None" />            <Setter Property="ResizeMode" Value="CanResize" />            <Setter Property="AllowsTransparency" Value="True" />            <Setter Property="WindowChrome.WindowChrome">                <Setter.Value>                    <WindowChrome CaptionHeight="30" ResizeBorderThickness="20" />                </Setter.Value>            </Setter>            <Setter Property="Template">                <Setter.Value>                    <ControlTemplate TargetType="Window">                        <Border Padding="10">                            <Border Background="White"                                    BorderBrush="Red"                                    BorderThickness="1"                                    CornerRadius="5"                                    SnapsToDevicePixels="True">                                <Border.Effect>                                    <DropShadowEffect BlurRadius="10"                                                      Direction="0"                                                      ShadowDepth="0" />                                </Border.Effect>                                <ContentPresenter />                            </Border>                        </Border>                    </ControlTemplate>                </Setter.Value>            </Setter>        </Style>    </Window.Style></Window>
