控件类是指与用户有交互作用的控件,例如文本框、按钮等
设置控件背景颜色
首先在界面定义一个按钮
<Window x:Class="WPF_CODE.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525">
<Grid>
<Button Name="btn1" Padding="10" Content="Hello" Width="Auto" Height="Auto" HorizontalAlignment="Center" VerticalAlignment="Center"/>
</Grid>
</Window>
从后端设置按钮的背景颜色:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Markup;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;
namespace WPF_CODE
{
/// <summary>
/// MainWindow.xaml 的交互逻辑
/// </summary>
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
}
//在窗体加载的时候设置按钮的背景
private void Window_Loaded(object sender, RoutedEventArgs e)
{
//Background为背景属性
//SolidColorBrush是一个实线的画刷类
//Colors类中内置多种颜色值
this.btn1.Background = new SolidColorBrush(Colors.Green);
}
}
}
效果:
通过XMAL设置:
<Window x:Class="WPF_CODE.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525" Loaded="Window_Loaded">
<Grid>
<!--通过Background来设置背景-->
<Button Name="btn1" Padding="10" Background="Red" Content="Hello" Width="Auto" Height="Auto" HorizontalAlignment="Center" VerticalAlignment="Center"/>
</Grid>
</Window>
效果:
在XMAL中设置背景不需要运行程序即可看到
设置控件前景色
从后端写:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Markup;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;
namespace WPF_CODE
{
/// <summary>
/// MainWindow.xaml 的交互逻辑
/// </summary>
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
}
//在窗体加载的时候设置按钮的背景
private void Window_Loaded(object sender, RoutedEventArgs e)
{
//Background为背景属性
//SolidColorBrush是一个实线的画刷类
//Colors类中内置多种颜色值
//this.btn1.Background = new SolidColorBrush(Colors.Green);
//Foreground为前景色,即字体的颜色
//SystemColors为系统里的颜色选择器(这是另一个选择)
this.btn1.Foreground = new SolidColorBrush(SystemColors.HighlightColor);
}
}
}
效果:
从前端写:
<Window x:Class="WPF_CODE.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525" Loaded="Window_Loaded">
<Grid>
<!--通过Foreground来设置前景-->
<Button Name="btn1" Padding="10" Foreground="Red" Content="Hello" Width="Auto" Height="Auto" HorizontalAlignment="Center" VerticalAlignment="Center"/>
</Grid>
</Window>
效果:
使用RGB设定颜色
示例:Color.FromRgb(255, 0, 0)
this.btn1.Background = new SolidColorBrush(Color.FromRgb(255, 0, 0));
RGB表示红绿蓝三个颜色值,第个值的范围是0~255
设置字体样式
字体常用的属性有:
- FontFamily - 字体家族
- FontSize - 字体大小
- FontStyle - 字体样式
- FontWeight - 字体粗细
示例:
FontFamily="宋体, Arial, Arvo"
多个字体名称可以用逗号隔开,从第一个开始匹配
FontSize="15"
设置字体大小
`` FontStyle="Italic" ` 设置字体为斜体
FontWeight="Bold"
设置字体不粗体
<Window x:Class="WPF_CODE.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525" Loaded="Window_Loaded">
<Grid>
<Button Name="btn1" Padding="10" FontFamily="宋体, Arial, Arvo" FontSize="15" FontStyle="Italic" FontWeight="Bold" Background="Green" Foreground="Red" Content="Hello" Width="Auto" Height="Auto" HorizontalAlignment="Center" VerticalAlignment="Center"/>
</Grid>
</Window>
效果:
如果不知道系统上的字体都有哪些,可以通过Font.SystemFontFamilies
来获取系统上的字体集合
List<object> list = new List<object>();
foreach (var item in Fonts.SystemFontFamilies)
{
list.Add(item.Source);
}
为文字添加下划线,相关属性TextDecorations
示例:
<TextBox TextDecorations="underline">Hello</TextBox>
该文本框的里的文字将现出一条下划线
将外部字体文件添加到代码中
字体文件的后缀为.ttf,将字体文件加载到项目中,然后通过路径将其赋值给FontFamily属性
示例:
<Window x:Class="WPF_CODE.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525" Loaded="Window_Loaded">
<Grid>
<TextBox TextDecorations="underline">Hello</TextBox>
<Button Name="btn1" Padding="10" FontFamily="./#Streamster" FontSize="15" FontStyle="Italic" FontWeight="Bold" Background="Green" Foreground="Red" Content="Hello" Width="Auto" Height="Auto" HorizontalAlignment="Center" VerticalAlignment="Center"/>
</Grid>
</Window>
FontFamily="./#Streamster"
文件名不需要加后缀,但是文件名前需要有#
符号,这点需要注意
效果:
WPF对于小字体呈现不美观
如果字体小于15,将会出现锯齿边源
<Window x:Class="WPF_CODE.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525" Loaded="Window_Loaded">
<Grid>
<Grid.RowDefinitions>
<RowDefinition></RowDefinition>
<RowDefinition></RowDefinition>
</Grid.RowDefinitions>
<TextBox Grid.Row="0" FontSize="12">Hello, my name is Jack!</TextBox>
<TextBlock Grid.Row="1" FontSize="20">Where am I?</TextBlock>
</Grid>
</Window>
可以看出,小字体明显不如大字体清晰
可以通过TextOptions.TextFormattingMode
属性来进行设置小字体搞锯齿效果
示例:
<Window x:Class="WPF_CODE.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525" Loaded="Window_Loaded">
<Grid>
<Grid.RowDefinitions>
<RowDefinition></RowDefinition>
<RowDefinition></RowDefinition>
</Grid.RowDefinitions>
<TextBox Grid.Row="0" FontSize="12" TextOptions.TextFormattingMode="Display">Hello, my name is Jack!</TextBox>
<TextBlock Grid.Row="1" FontSize="12">Where am I?</TextBlock>
</Grid>
</Window>
效果:
可以看出,同样大小的字体,设置过TextOptions.TextFormattingMode="Display"
属性的字体会更清晰一点
需要注意的是,此属性对于大于15的字体效果不佳
