Ich versuche, alle verfügbaren Schriftarten von Windows durch IDWriteFactory :: GetSystemFontCollection in C++ zu erhalten. Ich habe alle Microsoft MSDN-Schritte befolgt. Jetzt kann ich alle wichtigen Schriftarten erfolgreich erhalten, aber es werden keine "Varianten" -Schriften bereitgestellt.IDWriteFactory :: GetSystemFontCollection gibt keine Varianten von Schriftarten
ZB bekomme ich "Arial", aber kein "Arial Black" und "Arial Narrow", "Yu Gothic" aber kein "Yu Gothic Medium" und "Yu Gothic Light". Jeder weiß, wie man alle diese Schriften in C++ bekommt? Vielen Dank!
Unten ist mein Programm:
void wmain()
{
IDWriteFactory* pDWriteFactory = NULL;
HRESULT hr = DWriteCreateFactory(
DWRITE_FACTORY_TYPE_SHARED,
__uuidof(IDWriteFactory),
reinterpret_cast<IUnknown**>(&pDWriteFactory)
);
IDWriteFontCollection* pFontCollection = NULL;
// Get the system font collection.
if (SUCCEEDED(hr))
{
hr = pDWriteFactory->GetSystemFontCollection(&pFontCollection);
}
UINT32 familyCount = 0;
// Get the number of font families in the collection.
if (SUCCEEDED(hr))
{
familyCount = pFontCollection->GetFontFamilyCount();
}
for (UINT32 i = 0; i < familyCount; ++i)
{
IDWriteFontFamily* pFontFamily = NULL;
// Get the font family.
if (SUCCEEDED(hr))
{
hr = pFontCollection->GetFontFamily(i, &pFontFamily);
}
IDWriteLocalizedStrings* pFamilyNames = NULL;
// Get a list of localized strings for the family name.
if (SUCCEEDED(hr))
{
hr = pFontFamily->GetFamilyNames(&pFamilyNames);
}
UINT32 index = 0;
BOOL exists = false;
wchar_t localeName[LOCALE_NAME_MAX_LENGTH];
if (SUCCEEDED(hr))
{
// Get the default locale for this user.
int defaultLocaleSuccess = GetUserDefaultLocaleName(localeName, LOCALE_NAME_MAX_LENGTH);
// If the default locale is returned, find that locale name, otherwise use "en-us".
if (defaultLocaleSuccess)
{
hr = pFamilyNames->FindLocaleName(localeName, &index, &exists);
}
if (SUCCEEDED(hr) && !exists) // if the above find did not find a match, retry with US English
{
hr = pFamilyNames->FindLocaleName(L"en-us", &index, &exists);
}
}
// If the specified locale doesn't exist, select the first on the list.
if (!exists)
index = 0;
UINT32 length = 0;
// Get the string length.
if (SUCCEEDED(hr))
{
hr = pFamilyNames->GetStringLength(index, &length);
}
// Allocate a string big enough to hold the name.
wchar_t* name = new (std::nothrow) wchar_t[length+1];
if (name == NULL)
{
hr = E_OUTOFMEMORY;
}
// Get the family name.
if (SUCCEEDED(hr))
{
hr = pFamilyNames->GetString(index, name, length+1);
}
if (SUCCEEDED(hr))
{
// Print out the family name.
wprintf(L"%s\n", name);
}
}
}
Danke! Das hat funktioniert! – user3508838
