Get lists of all installed fonts in combo box uwp

Question

Please help me to get all installed fonts in UWP. I have seen so many articles to use System.Drawing.Text but I did not find any reference to it. So, please help me to get list all installed font families for combo box

Answer 1

Hello @Binamra Lamsal Welcome to Microsoft Q&A,

As @Ken Tucker said, you could use Win2D api to get list of install font. and render it in the listview.

System.NullReferenceException: 'Object reference not set to an instance of an object.'

comboFonts was null.

The problem is you set the ItemsSource before this.InitializeComponent(); method that will cause the listview has not render yet.

please call above method in the OnNavigatedTo method.

 protected override void OnNavigatedTo(NavigationEventArgs e)  
    {  
        base.OnNavigatedTo(e);  

        var fonts = Microsoft.Graphics.Canvas.Text.CanvasTextFormat.GetSystemFontFamilies();  
        comboFonts.ItemsSource = fonts;  
    }  

Xaml Code

  <Grid>  
        <ListView x:Name="comboFonts"></ListView>  
    </Grid>

Add the Nuget package Win2D to your app then you can get a font list like this

         var fonts = Microsoft.Graphics.Canvas.Text.CanvasTextFormat.GetSystemFontFamilies();
         comboFonts.ItemsSource = fonts;

You can use EnumFontFamiliesEx

A test (with ComboBox1 ComboBox, you can change the added string sText ) :

public int FontCallback(ref ENUMLOGFONTEX lpelfe, ref NEWTEXTMETRICEX lpntme, uint FontType, IntPtr lParam)  
{  
    string sText = lpelfe.lfFaceName + " (" + lpelfe.elfScript + ", " + (lpelfe.elfStyle !=""?lpelfe.elfStyle:"No style") + ")";  
    ComboBox1.Items.Add(sText);          
    return 1;  
}  

:

IntPtr hDC = GetDC(IntPtr.Zero);                                                                   
LOGFONT lf = new LOGFONT();                                                     
lf.lfCharSet = DEFAULT_CHARSET;                                                 
EnumFontFamExProc enumFontFamExProc = new EnumFontFamExProc(FontCallback);    [DllImport("Gdi32.dll", CharSet = CharSet.Unicode)]  
int nRet = EnumFontFamiliesEx(hDC, ref lf, enumFontFamExProc, IntPtr.Zero, 0);public static extern int EnumFontFamiliesEx(IntPtr hdc, ref LOGFONT lpLogfont, EnumFontFamExProc lpEnumFontFamExProc, IntPtr lParam, uint dwFlags);  
ReleaseDC(IntPtr.Zero, hDC);
