WPF自定义控件与样式(13)-自定义窗体Window & 自适应内容大小消息框MessageBox

一．前言

　　申明：WPF自定义控件与样式是一个系列文章，前后是有些关联的，但大多是按照由简到繁的顺序逐步发布的等，若有不明白的地方可以参考本系列前面的文章，文末附有部分文章链接。

　　本文主要内容：

• 自定义Window窗体样式；
• 基于自定义窗体实现自定义MessageBox消息提示框；

二．自定义Window窗体样式

　　自定义的Window窗体效果：

 

　　因为WPF默认的窗体比较简陋，大都需要自己实现Window窗体样式效果，基本思路很简单：

• 第一步：干掉默认样式：WindowStyle = WindowStyle.None；
• 第二步：设置窗体透明：AllowsTransparency = true；
• 第三步：设置自己的窗体样式；

　　这样从外观样式上可以满足，但做为窗体该具备的基本功能还没有，需要另外来实现了：

• 窗体Icon、标题栏（可以通过样式实现）；
• 窗体的基本按钮：最小化、最大化、关闭按钮；
• 窗体的鼠标拖动；
• 好像Win8、Win10的功能吧，窗体拖动到桌面边缘自动最大化、还原；
• 鼠标调整窗口大小；
• 双击标题栏最大化、还原；

　　上面的功能在本文中，一部分是自定义实现的，还有一部分是用了一个开源库（Microsoft.Windows.Shell）用于实现窗体大小、拖放等窗体基本功能，Microsoft.Windows.Shell文件下载：点我下载。

　　进入正题，自定义窗体WindowBase的后台C#代码：

　　WindowBase的样式有两个，一个是基础样式BaseWindowStyle，可以自定义头部标题栏，提供更多定制需求。另一个样式DefaultWindowStyle为默认窗体样式，用于大多数不要特别定制的窗体需求。BaseWindowStyle样式代码：

三．实现自定义MessageBox消息提示框

　　基于第二节自定义的窗体WindowBase，实现自定义的MessageBox就简单了，效果图：

　　仔细观察，不难发现上面的窗体大小是根据内容的多少自适应的。窗体自适应内容的的关键设置就是SizeToContent="WidthAndHeight"，但为了达到更好的效果控制，还需要控制内容的大小范围，范围可以自己调整，看了样式代码你就了解了：  

<local:WindowBase x:Class="System.Windows.MessageBoxX"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:shell="http://schemas.microsoft.com/winfx/2006/xaml/presentation/shell"
        xmlns:local="clr-namespace:XLY.Framework.Controls" 
        MaxboxEnable="False" MinboxEnable="False" ResizeMode="NoResize" FIcon="&#xe608;" x:Name="mb" 
        Title="MessageBox" ShowInTaskbar="False" SizeToContent="WidthAndHeight"  Style="{StaticResource DefaultWindowStyle}" CaptionHeight="24"> 
    <local:WindowBase.InputBindings>
        <KeyBinding Key="Escape" Command="{x:Static shell:SystemCommands.CloseWindowCommand}"/>
    </local:WindowBase.InputBindings>
    <Grid>
        <Grid Margin="5,8,5,5">
            <Grid.RowDefinitions>
                <RowDefinition Height="*"/>
                <RowDefinition Height="60"/>
            </Grid.RowDefinitions>
            <Grid.ColumnDefinitions>
                <ColumnDefinition Width="100"/>
                <ColumnDefinition Width="*"/>
            </Grid.ColumnDefinitions>
            <TextBlock x:Name="ficon" HorizontalAlignment="Right" FontSize="80" Text="&#xe61c;" Foreground="{Binding Foreground,ElementName=mb}" Style="{StaticResource FIcon}" Margin="5"/>
            <TextBlock x:Name="txtMessage" Grid.Column="1" VerticalAlignment="Center" HorizontalAlignment="Left" Foreground="{Binding Foreground,ElementName=mb}" 
                       FontSize="{Binding FontSize,ElementName=mb}" TextWrapping="Wrap" 
                   Margin="5,20,10,20" MinWidth="260" MaxWidth="420">新建一个WPF程序在Windows8下面就会出现左边的窗口边框，颜色取决于Windows主题我想在想创建一个右边那样的窗口，要么是窄边，要么没有边</TextBlock>

            <StackPanel Orientation="Horizontal" VerticalAlignment="Top" Margin="1" Grid.Column="0" Grid.Row="1" Grid.ColumnSpan="2" HorizontalAlignment="Center">
                <local:FButton x:Name="btnOK" FIcon="&#xe646;" Width="85" Height="30" CornerRadius="0" Margin="5,5,20,5" Click="btnOK_Click">确定</local:FButton>
                <local:FButton x:Name="btnCancel" FIcon="&#xe60a;" Width="85" Height="30" CornerRadius="0"
                           Margin="20,5,10,5" Click="btnCancel_Click">取消</local:FButton>
            </StackPanel>
        </Grid>
    </Grid>

</local:WindowBase>

　　上面不同消息类型的颜色资源：  

    <!--MessageBoxX-->
    <SolidColorBrush x:Key="InfoForeground" Color="White"></SolidColorBrush>
    <SolidColorBrush x:Key="QuestionForeground" Color="#74B80C"></SolidColorBrush>
    <SolidColorBrush x:Key="WarningForeground" Color="DarkOrange"></SolidColorBrush>
    <SolidColorBrush x:Key="ErrorForeground" Color="#E74E4E"></SolidColorBrush>

                _Brushes.Add(key, b);
            }
            this.Foreground = _Brushes[key];
