WinUI3下TitleBar的自定义
对于Windows软件开发者来说重写标题栏样式是一个很重要的事情,在WPF阶段很多人写出来性能很差的窗口,而且为了适配Win11系统的Snaplayout后性能就更差了,这篇是写WinUI3下提供的重写TitleBar的方式;
1、修改文本
public MainWindow()
{
this.InitializeComponent();
Title = "Duwenlong learn App Title";
}
可以修改默认标题栏显示文本;但是无法自定义其他内容;所有操作都请在InitializeComponent方法后执行,不然会报错;
public MainWindow()
{
this.InitializeComponent();
// Hide default title bar.
ExtendsContentIntoTitleBar = true;
}
修改后我们有完整的区域用看显示内容,只是目前还比较丑而且标题栏部分不支持拖动;
2、完全自定义
通过调用 Window.SetTitleBar 方法并传入定义拖动区域的 UIElement 来指定拖动区域。
1、标题栏内容和拖动区域
代码如下:
<Window
x:Class="TitleBarCustomizationDemo.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:TitleBarCustomizationDemo"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<Grid x:Name="AppTitleBar">
<TextBlock x:Name="AppTitleTextBlock" Text="Duwenlong learn Now App Title"
TextWrapping="NoWrap"
Style="{StaticResource CaptionTextBlockStyle}"
VerticalAlignment="Center"
Margin="28,6,0,6"/>
</Grid>
</Grid>
</Window>
public MainWindow()
{
this.InitializeComponent();
ExtendsContentIntoTitleBar = true;
SetTitleBar(AppTitleBar);
}
2、交互式内容
我们可以放置一些不影响用户的交互式按钮
使用XAML的嵌套语法尝试放置一些内容,我放置了一个textblock,用于在标题栏显示一个消息;
<Window
x:Class="TitleBarCustomizationDemo.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:TitleBarCustomizationDemo"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<Grid x:Name="AppTitleBar" >
<TextBlock x:Name="AppTitleTextBlock" Text="Duwenlong learn Now App Title"
TextWrapping="NoWrap" Margin="28,6,0,6"
Style="{StaticResource CaptionTextBlockStyle}"
VerticalAlignment="Center"
/>
<TextBlock Margin="28,6,0,6" Text="1 problem to be fixed" Width="220"/>
</Grid>
</Grid>
</Window>
4、系统标题按钮的颜色和透明度
将应用内容扩展到标题栏区域时,可以使标题按钮的背景透明,我默认设置了WindowCaptionBackground为透明色
<Application
x:Class="TitleBarCustomizationDemo.App"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:TitleBarCustomizationDemo">
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<XamlControlsResources xmlns="using:Microsoft.UI.Xaml.Controls" />
<!-- Other merged dictionaries here -->
</ResourceDictionary.MergedDictionaries>
<!-- Other app resources here -->
<SolidColorBrush x:Key="WindowCaptionBackground">Transparent</SolidColorBrush>
<SolidColorBrush x:Key="WindowCaptionBackgroundDisabled">LightGreen</SolidColorBrush>
<SolidColorBrush x:Key="WindowCaptionForeground">Red</SolidColorBrush>
<SolidColorBrush x:Key="WindowCaptionForegroundDisabled">Pink</SolidColorBrush>
</ResourceDictionary>
</Application.Resources>
</Application>
5、当窗口处于非活动状态时,调暗标题栏
<Application
x:Class="TitleBarCustomizationDemo.App"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:TitleBarCustomizationDemo">
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<XamlControlsResources xmlns="using:Microsoft.UI.Xaml.Controls" />
<!-- Other merged dictionaries here -->
</ResourceDictionary.MergedDictionaries>
<!-- Other app resources here -->
<!-- <SolidColorBrush x:Key="WindowCaptionBackground">Transparent</SolidColorBrush> -->
<SolidColorBrush x:Key="WindowCaptionBackground">Green</SolidColorBrush>
<SolidColorBrush x:Key="WindowCaptionBackgroundDisabled">LightGreen</SolidColorBrush>
<SolidColorBrush x:Key="WindowCaptionForeground">Red</SolidColorBrush>
<SolidColorBrush x:Key="WindowCaptionForegroundDisabled">Pink</SolidColorBrush>
</ResourceDictionary>
</Application.Resources>
</Application>
using Microsoft.UI.Xaml;
using Microsoft.UI.Xaml.Controls;
using Microsoft.UI.Xaml.Controls.Primitives;
using Microsoft.UI.Xaml.Data;
using Microsoft.UI.Xaml.Input;
using Microsoft.UI.Xaml.Media;
using Microsoft.UI.Xaml.Navigation;
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Runtime.InteropServices.WindowsRuntime;
using Windows.Foundation;
using Windows.Foundation.Collections;
// To learn more about WinUI, the WinUI project structure,
// and more about our project templates, see: http://aka.ms/winui-project-info.
namespace TitleBarCustomizationDemo
{
/// <summary>
/// An empty window that can be used on its own or navigated to within a Frame.
/// </summary>
public sealed partial class MainWindow : Window
{
public MainWindow()
{
this.InitializeComponent();
ExtendsContentIntoTitleBar = true;
SetTitleBar(AppTitleBar);
Activated += MainWindow_Activated;
}
private void MainWindow_Activated(object sender, WindowActivatedEventArgs args)
{
if (args.WindowActivationState == WindowActivationState.Deactivated)
{
AppTitleTextBlock.Foreground =
(SolidColorBrush)App.Current.Resources["WindowCaptionForegroundDisabled"];
}
else
{
AppTitleTextBlock.Foreground =
(SolidColorBrush)App.Current.Resources["WindowCaptionForeground"];
}
}
}
}
6、重置标题栏
可以在应用运行时调用 SetTitleBar 切换到新的标题栏元素。或者恢复为默认;
<Window
x:Class="TitleBarCustomizationDemo.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:TitleBarCustomizationDemo"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<Grid x:Name="AppTitleBar" >
<TextBlock x:Name="AppTitleTextBlock" Text="Duwenlong learn Now App Title"
TextWrapping="NoWrap" Margin="28,6,0,6"
Style="{StaticResource CaptionTextBlockStyle}"
VerticalAlignment="Center"
/>
<TextBlock Margin="28,6,0,6" Text="1 problem to be fixed" Width="220"/>
</Grid>
<Button Grid.Row="1" Content="Click Me" Click="Button_Click"/>
</Grid>
</Window>
private void Button_Click(object sender, RoutedEventArgs e)
{
SetTitleBar(null);
ExtendsContentIntoTitleBar = false;
}
因为使用的是Win10机器,图床又挂了所以不贴图了,Win11下会很好看。
