[UWP] [XAML] FontIcon在使用C ++ / WinRT动态绑定其Glyph值时无法正确显示字形 [英] [UWP][XAML] FontIcon not displaying the glyph correctly when binding its Glyph value dynamically using C++/WinRT

问题描述

< FontIcon FontFamily =" Segoe MDL2 Assets" Glyph =" {x：Bind myGlyph}"> < / FontIcon> 

这会显示一堆矩形而不是正确的字形。但是如果我直接硬编码字形值，例如：&&＃xE768;"它会正常工作。

我怀疑它与hstring的转换有关，必须碰巧绑定该值。

解决方案

确保实体"&＃ xE768;"仅在XAML字符串文字中有效。如果您想在C ++代码中指定相同的字形，请使用  L" \ xE768"

<FontIcon FontFamily="Segoe MDL2 Assets" Glyph="{x:Bind myGlyph}"> </FontIcon>

This displays a bunch of rectangles instead of the correct glyph. But if I hard code the glyph value directly, for example: "" it will work correctly.

I suspect it has something to do with the conversion from hstring that has to happen to bind the value.

解决方案

Hi,

Make sure that the entity "" is valid only in XAML string literals. If you'd like to specify the same glyph in C++ code, use L"\xE768" .
