列舉已安裝的字型

InstalledFontCollection類別繼承自FontCollection抽象基類。 您可以使用 InstalledFontCollection 物件來列舉電腦上安裝的字型。 InstalledFontCollection物件的FontCollection：：GetFamilies方法會傳回FontFamily物件的陣列。 呼叫 FontCollection：：GetFamilies之前，您必須配置足以保存該陣列的緩衝區。 若要判斷必要緩衝區的大小，請呼叫 FontCollection：：GetFamilyCount 方法，並將傳回值乘以 sizeof (FontFamily) 。

下列範例會列出電腦上安裝的所有字型系列名稱。 程式碼會呼叫FontCollection：：GetFamilies所傳回陣列中每個FontFamily 物件的 FontFamily：：GetFamilyName方法，以擷取字型系列名稱。 擷取系列名稱時，會串連以形成逗號分隔的清單。 然後Graphics類別的DrawString方法會在矩形中繪製逗號分隔清單。

FontFamily   fontFamily(L"Arial");
Font         font(&fontFamily, 8, FontStyleRegular, UnitPoint);
RectF        rectF(10.0f, 10.0f, 500.0f, 500.0f);
SolidBrush   solidBrush(Color(255, 0, 0, 0));

INT          count = 0;
INT          found = 0;
WCHAR        familyName[LF_FACESIZE];  // enough space for one family name
WCHAR*       familyList = NULL;
FontFamily*  pFontFamily = NULL;

InstalledFontCollection installedFontCollection;

// How many font families are installed?
count = installedFontCollection.GetFamilyCount();

// Allocate a buffer to hold the array of FontFamily
// objects returned by GetFamilies.
pFontFamily = new FontFamily[count];

// Get the array of FontFamily objects.
installedFontCollection.GetFamilies(count, pFontFamily, &found);

// The loop below creates a large string that is a comma-separated
// list of all font family names.
// Allocate a buffer large enough to hold that string.
familyList = new WCHAR[count*(sizeof(familyName)+ 3)];
StringCchCopy(familyList, 1, L"");

for(INT j = 0; j < count; ++j)
{
   pFontFamily[j].GetFamilyName(familyName);  
   StringCchCatW(familyList, count*(sizeof(familyName)+ 3), familyName);
   StringCchCatW(familyList, count*(sizeof(familyName)+ 3), L",  ");
}

// Draw the large string (list of all families) in a rectangle.
graphics.DrawString(
   familyList, -1, &font, rectF, NULL, &solidBrush);

delete [] pFontFamily;
delete [] familyList;
