WPF中Window相信大家都很熟悉,有時(shí)我們有一些自定義需求默認(rèn)Window是無(wú)法滿足的,所以本文就來(lái)和大家聊聊WPF如何封裝一個(gè)可擴(kuò)展的Window吧

前言

WPF中Window相信大家都很熟悉，有時(shí)我們有一些自定義需求默認(rèn)Window是無(wú)法滿足的，比如在標(biāo)題欄上放一些自己東西，這個(gè)時(shí)候我們就需要寫(xiě)一個(gè)自己的Window，實(shí)現(xiàn)起來(lái)也很簡(jiǎn)單，只要給Window設(shè)置一個(gè)WindowChrome.WindowChrome附加屬性就可以實(shí)現(xiàn)，WindowChrome 可以讓你自定義窗口的非工作區(qū)的外觀和行為。非工作區(qū)就是窗口的標(biāo)題欄和邊框，通常由操作系統(tǒng)繪制和管理。WindowChrome 可以讓你將 WPF 的內(nèi)容擴(kuò)展到非工作區(qū)，同時(shí)保留一些系統(tǒng)的功能和行為，比如調(diào)整大小，移動(dòng)，最大化，最小化等。

一、示例代碼

1.1 基本使用

<local:CustomWindow
    x:Class="CustomWindowDemo.Window1"
    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:CustomWindowDemo"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    Title="Window1"
    Width="800"
    Height="450"
    Icon="/logo.png"
    mc:Ignorable="d">
    <Grid />
</local:CustomWindow>

1.2 自定義標(biāo)題欄高度

<local:CustomWindow
    x:Class="CustomWindowDemo.Window1"
    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:CustomWindowDemo"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    Title="Window1"
    Width="800"
    Height="450"
    CaptionHeight="35"
    Icon="/logo.png"
    mc:Ignorable="d">
    <Grid />
</local:CustomWindow>

1.3 自定義標(biāo)題欄顏色

<local:CustomWindow
    x:Class="CustomWindowDemo.Window1"
    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:CustomWindowDemo"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    Title="Window1"
    Width="800"
    Height="450"
    CaptionBackground="Blue"
    Icon="/logo.png"
    mc:Ignorable="d">
    <Grid />
</local:CustomWindow>

1.4 自定義標(biāo)題欄內(nèi)容

<local:CustomWindow
    x:Class="CustomWindowDemo.Window1"
    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:CustomWindowDemo"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    Title="Window1"
    Width="800"
    Height="450"
    Icon="/logo.png"
    mc:Ignorable="d">
    <local:CustomWindow.CaptionBarContent>
        <Grid>
            <Grid.ColumnDefinitions>
                <ColumnDefinition Width="Auto" />
                <ColumnDefinition Width="*" />
                <ColumnDefinition Width="Auto" />
            </Grid.ColumnDefinitions>

            <Button
                Margin="5"
                Padding="2"
                VerticalAlignment="Center"
                Background="Transparent"
                BorderThickness="0"
                WindowChrome.IsHitTestVisibleInChrome="True">
                <StackPanel Orientation="Horizontal">
                    <Polygon
                        VerticalAlignment="Center"
                        Fill="White"
                        Points="0,6 6,0 6,12" />
                    <TextBlock
                        Margin="4,0,0,0"
                        VerticalAlignment="Center"
                        FontSize="14"
                        Foreground="White"
                        Text="返回" />
                </StackPanel>
            </Button>
            <TextBlock
                Grid.Column="1"
                HorizontalAlignment="Center"
                VerticalAlignment="Center"
                FontSize="14"
                Foreground="White"
                Text="{Binding RelativeSource={RelativeSource AncestorType=Window}, Path=Title}" />
            <Button
                Grid.Column="2"
                Margin="5"
                Padding="2"
                VerticalAlignment="Center"
                Background="Transparent"
                BorderThickness="0"
                FontSize="14"
                Foreground="White"
                WindowChrome.IsHitTestVisibleInChrome="True">
                <StackPanel Orientation="Horizontal">
                    <TextBlock
                        Margin="0,0,4,0"
                        VerticalAlignment="Center"
                        Text="Admin" />
                    <Polyline
                        VerticalAlignment="Center"
                        Points="0,0 5,5 10,0"
