WPF利用WindowChrome實現(xiàn)自定義窗口

更新時間：2023年02月16日 14:47:04 作者：黑夜中的潛行者

這篇文章主要為大家詳細介紹了WPF如何利用WindowChrome實現(xiàn)自定義窗口，文中的示例代碼講解詳細，具有一定的借鑒價值，需要的可以參考一下

簡介

Microsoft官網(wǎng)關(guān)于 WindowChome 的介紹

截取Microsoft文章的一段話：

若要在保留其標準功能時自定義窗口，可以使用該 WindowChrome 類。該 WindowChrome 類將窗口框架的功能與視覺對象分開，并允許你控制應(yīng)用程序窗口的客戶端和非客戶端區(qū)域之間的邊界。通過 WindowChrome 該類，可以通過擴展工作區(qū)來覆蓋非工作區(qū)，將 WPF 內(nèi)容置于窗口框架中。同時，它通過兩個不可見區(qū)域保留系統(tǒng)行為：調(diào)整邊框和標題區(qū)域的大小。

布局實現(xiàn)

首先我們需要在 MainWindow 也就是我們的主窗口中的 Window.Resources 中實現(xiàn) WindowChrome 的基本樣式：

WindowChrome.ResizeBorderThickness 設(shè)置不可見邊框?qū)挾?/p>

WindowChrome.CaptionHeight> 設(shè)置屬于標題欄的范圍——高度

WindowChrome.UseAeroCaptionButtons 是否啟用默認系統(tǒng)按鈕功能——三大金剛鍵

WindowChrome.NonClientFrameEdges 設(shè)置客戶區(qū)域，使用 bottom 可以實現(xiàn)加載時空白窗口而不顯示默認窗口，提升用戶體驗

<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>

重寫窗口，實現(xiàn)最大化窗口下，標題欄及客戶區(qū)域偏移問題的修正。

通過代碼獲取當前窗口的工作區(qū)域，及任務(wù)欄以外的其他區(qū)域

System.Windows.SystemParameters.WorkArea.Width 獲取工作區(qū)域的寬

System.Windows.SystemParameters.WorkArea.Height 獲取工作區(qū)域的高

為什么要使用 ValueConverter 主要是因為 WorkArea 返回的類型無法直接 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();
        }
    }
}
