windows fontsssss

OpenGL OpenGL: Advanced Coding

Hi

Anyone know if its possible to maintain sets of font lists
(wglUseFontBitmaps - MS windows)) across multiple opengl rendering contexts.

Here its actually a single opengl window, that is closed and opened by the
user, creating font lists on each window creation is rather expensive.
Both the opengl rendering context and windows HDC are lost - so is it
possible to hold on to a list between contexts ?

Thanks

Typical code we are using is

unsigned int base; // Base display list for font
HFONT font; // Windows font ID

                             // create rendering context and make it

current
hRC = wglCreateContext(hDC);

wglMakeCurrent(hDC, hRC);

if ((base = glGenLists(96)) == 0)
return (0);

if (stricmp(typeface, “symbol”) == 0) // font symbols a bit different
font = CreateFont(height, 0, 0, 0, weight, italic, FALSE, FALSE,
SYMBOL_CHARSET, OUT_TT_PRECIS,
CLIP_DEFAULT_PRECIS, DRAFT_QUALITY,
DEFAULT_PITCH, typeface);
else
font = CreateFont(height, 0, 0, 0, weight, italic, FALSE, FALSE,
ANSI_CHARSET, OUT_TT_PRECIS,
CLIP_DEFAULT_PRECIS, DRAFT_QUALITY,
DEFAULT_PITCH, typeface);

HGDIOBJ hOldFont = ::SelectObject(hdc, font);

BOOL fRC = wglUseFontBitmaps(hdc, 32, 96, base);

::SelectObject(hdc, hOldFont);
