Gar*_*eth 15 c# wpf fonts xaml font-awesome
我正在使用Font Awesome的图标来渲染C#WPF应用程序中的基本字体图像.在运行期间,当我尝试更改TextBlock以显示不同的字体图标但显示unicode表示而不是字体图标时.
我已经创建了一个示例应用程序来显示它.单击任一按钮时,它会将TextBlock的Text属性替换为相应图标的unicode.项目中有一个Resources文件夹,其中FontAwesome.ttf字体文件作为构建资源,TextBlock的FontFamily属性引用该文件.
这是我的示例应用程序的源代码:
代码隐藏:
namespace FontAwesomeTest
{
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
}
private void btnGlass_Click(object sender, RoutedEventArgs e)
{
tblkFontIcon.Text = "";
}
private void btnMusic_Click(object sender, RoutedEventArgs e)
{
tblkFontIcon.Text = "";
}
private void btnSearch_Click(object sender, RoutedEventArgs e)
{
tblkFontIcon.Text = "";
}
}
}

我使用以下教程将Font Awesome合并到我的应用程序中http://www.codeproject.com/Tips/634540/Using-Font-Icons
所以从本质上讲,我如何更改Icon但是有一个Icon显示 - 而不是Unicode?
提前致谢.

我知道这是一个老问题,但Font Awesome有一个名为FontAwesome.UWP和FontAwesome.WPF的NuGet包.只需下载其中一个.
如果您将使用图标导入跟随命名空间到您的XAML代码中:
xmlns:fa="http://schemas.fontawesome.io/icons/"

像这样在你的按钮中使用它:
<Button x:Name="btnButton">
<Button.Content>
<fa:ImageAwesome Icon="LongArrowLeft"/>
</Button.Content>
</Button>

最后在你的C#代码背后:
using FontAwesome.WPF; // on the top of the code
btnButton.Content = FontAwesomeIcon.LongArrowRight;

我找到了一个关于这个主题的不同帖子 - 在wpf中添加图标字体 我认为这应该更有可能是你想要的.
确保将您的字体添加为资源.然后,使用以下字符串:
Run Code Online (Sandbox Code Playgroud)<Setter Property="TextElement.FontFamily" Value="pack://application:,,,/fonts/#FontAwesome" />在上面的字符串中,我假设字体的名称(不是字体的文件名)是FontAwesome.
你只需要:
TextBlock.Text您喜欢的图标并将样式应用于TextBlock.如果要通过更新TextBlock.Text属性来更改图标,则应Text使用支持的unicode字符串设置该属性.
尝试类似的东西
tblkFontIcon.Text = "\uf000";

而不是
tblkFontIcon.Text = "";

然后你可能错过了那篇文章中的"工作原理"一节.您应该使用该标记扩展,而不是使用TextBlock.Text属性.
在他的示例代码中:
<RibbonButton Label="Import data"
LargeImageSource="{WpfTools:ImageFromFont Text=,
FontFamily=/RibbonFontIconSample;component/Resources/#FontAwesome, Brush=Brown}" />

注意WpfTools:ImageFromFont,它是Markup Extention,它允许xaml解析器进行转换
{WpfTools:ImageFromFont Text=,
FontFamily=/RibbonFontIconSample;component/Resources/#FontAwesome, Brush=Brown}

到 ImageSource和分配给LargeImageSource财产.
因此,在您的XAML,你可以更换TextBlock用Image,那么就应该是这样的:
<Image Source="{WpfTools:ImageFromFont Text=,
FontFamily=/RibbonFontIconSample;component/Resources/#FontAwesome, Brush=Brown}" />

如果要更改图标,则必须更改ImageSource自己,只需按照使用字体图标创建自己的方法,或者只是从该教程中复制以下代码.
private static ImageSource CreateGlyph(string text,
FontFamily fontFamily, FontStyle fontStyle, FontWeight fontWeight,
FontStretch fontStretch, Brush foreBrush)
{
if (fontFamily != null && !String.IsNullOrEmpty(text))
{
Typeface typeface = new Typeface(fontFamily, fontStyle, fontWeight, fontStretch);
GlyphTypeface glyphTypeface;
if (!typeface.TryGetGlyphTypeface(out glyphTypeface))
throw new InvalidOperationException("No glyphtypeface found");
ushort[] glyphIndexes = new ushort[text.Length];
double[] advanceWidths = new double[text.Length];
for (int n = 0; n < text.Length; n++)
{
ushort glyphIndex = glyphTypeface.CharacterToGlyphMap[text[n]];
glyphIndexes[n] = glyphIndex;
double width = glyphTypeface.AdvanceWidths[glyphIndex] * 1.0;
advanceWidths[n] = width;
}
GlyphRun gr = new GlyphRun(glyphTypeface, 0, false, 1.0, glyphIndexes,
new Point(0, 0), advanceWidths,
null, null, null, null, null, null);
GlyphRunDrawing glyphRunDrawing = new GlyphRunDrawing(foreBrush, gr);
return new DrawingImage(glyphRunDrawing);
}
return null;
}
