Style样式

1. 用法介绍
2. 样式多样性
3. 全局样式说明和资源字典的使用

1. 用法介绍

在这里插入图片描述

提前写好样式，让他作用于所有按钮

<Window x:Class="WPF_Study_Solution.window3"
        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"
        xmlns:local="clr-namespace:WPF_Study_Solution"
        mc:Ignorable="d"
        Title="window3" Height="450" Width="800">

    <Window.Resources>
        <Style TargetType="Button">
            <Setter Property="Background" Value="Green"/>
            <Setter Property="FontSize" Value="20"/>
            <Setter Property="Width" Value="200"/>
            <Setter Property="Height" Value="30"/>
        </Style>
    </Window.Resources>
    
    <StackPanel>
        <Button Content="登录"/>
        <Button Content="退出"/>
        <Button Content="忘记密码"/>
    </StackPanel>
</Window>

2. 样式多样性

写一个共有的样式
在基于这个样式写新的样式
类似于继承

在这里插入图片描述

<Window x:Class="WPF_Study_Solution.window3"
        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"
        xmlns:local="clr-namespace:WPF_Study_Solution"
        mc:Ignorable="d"
        Title="window3" Height="450" Width="800">

    <Window.Resources>

        <Style TargetType="Button">
            <Setter Property="Background" Value="WhiteSmoke"/>
            <Setter Property="FontSize" Value="20"/>
            <Setter Property="Margin" Value="20,10"/>
        </Style>

        <Style x:Key="LoginStyle" TargetType="Button" BasedOn="{StaticResource {x:Type Button}}">
            <Setter Property="Background" Value="Green"/>
        </Style>

        <Style x:Key="QuitStyle" TargetType="Button" BasedOn="{StaticResource {x:Type Button}}">
            <Setter Property="Background" Value="Red"/>
        </Style>

    </Window.Resources>
    
    <StackPanel>
        <Button Style="{StaticResource LoginStyle}" Content="登录"/>
        <Button Style="{StaticResource QuitStyle}" Content="退出"/>
        <Button  Content="忘记密码"/>
    </StackPanel>
</Window>

3. 全局样式说明和资源字典的使用

新建 资源字典 ，在资源字典中写全局Style样式 ，这样这个工程下的所有界面都可以使用这个 Style.

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                    xmlns:local="clr-namespace:WPF_Study_Solution">
    <Style TargetType="Button">
        <Setter Property="Background" Value="WhiteSmoke"/>
        <Setter Property="FontSize" Value="20"/>
        <Setter Property="Margin" Value="20,10"/>
    </Style>
    <Style x:Key="LoginStyle" TargetType="Button" BasedOn="{StaticResource {x:Type Button}}">
        <Setter Property="Background" Value="Green"/>
    </Style>
    <Style x:Key="QuitStyle" TargetType="Button" BasedOn="{StaticResource {x:Type Button}}">
        <Setter Property="Background" Value="Red"/>
    </Style>
</ResourceDictionary>

然后在 App.xaml 中引用全局样式资源

<Application x:Class="WPF_Study_Solution.App"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:local="clr-namespace:WPF_Study_Solution"
             StartupUri="MainWindow.xaml">
    <Application.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="/WPF_Study_Solution;component/BaseButtonStyle.xaml"/>
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </Application.Resources>
</Application>

在界面中使用全局样式

<Window x:Class="WPF_Study_Solution.window3"
        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"
        xmlns:local="clr-namespace:WPF_Study_Solution"
        mc:Ignorable="d"
        Title="window3" Height="450" Width="800">

    <StackPanel>
        <Button Style="{StaticResource LoginStyle}" Content="登录"/>
        <Button Style="{StaticResource QuitStyle}" Content="退出"/>
        <Button  Content="忘记密码"/>
    </StackPanel>
</Window>
