I really just started messing around with bitmap fonts and I''m having some trouble... First of all, spaces aren''t showing up as spaces. Instead, they are completely ignored and the words all run together. My second problem occurs when I try to create two instances of a simple font class that I created. The class just holds the HFONT handle and a variable for the display list base, and the constructor calls CreateFont(), SelectObject(), and wglUseFontBitmaps(). Then there is a Select() member func that selects it as the current font and a Print() member function that handles the printing. Like I said, everything works fine except for printing spaces UNTIL I try to create a second instance and print with it. It''s like it completely ignores the second font. Here''s sort of what the code that creates and uses it looks like (summarized)... // --- Global variables --- CGLFont font1("Arial Black", 14, FW_BOLD); CGLFont font2("Courier", 10, FW_BOLD); void MyRenderingFunc( void ) { // All my other OpenGL rendering type stuff font1.Select(); font1.Print("This is a test..."); font2.Select(); font2.Print("But it will be in Arial andwithnospaces."); //... }

Actually, most of these functions are pretty much snippets from the OpenGL Game Programming book...

This is just an incredibly simple little class that doesn't even do enough to warrant being its own class (yet)...

Here is the whole thing at the moment...

class CGLFont
{
public:
HFONT m_hFont;
unsigned int m_nListBase;

//Constructor
CGLFont( char *name, int height, int weight);

void Select( HDC hDC ); //make it the current font
void Print ( char *text ); //Print a string...

};

CGLFont::CGLFont( char *name, int height, int weight)
{
m_nListBase = glGenLists(96);

m_hFont = CreateFont( height, 0, 0, 0, weight,
FALSE, FALSE, FALSE, ANSI_CHARSET,
OUT_TT_PRECIS, CLIP_DEFAULT_PRECIS, ANTIALIASED_QUALITY, FF_DONTCARE | DEFAULT_PITCH, name );
}


void CGLFont::Select( HDC hDC )
{
SelectObject(hDC, m_hFont);
wglUseFontBitmaps(hDC, 32, 96, m_nListBase);
}

void CGLFont:rint( char *text )
{
glPushAttrib(GL_LIST_BIT);

glListBase(m_nListBase - 32);
glCallLists(strlen(text), GL_UNSIGNED_BYTE, text);

glPopAttrib();
}

So, basically, once I use CreateFont(), make it current, and call wglUseFontBitmaps(), I can toss the HFONT variable...

Then I can just select the instance of CGLFont that I want to use by calling wglUseFontBitmaps()?

Yesterday I used Nehe''s lesson 13 to make a font class, and it works good, but I was wondering, is there any way to get around using the hDC?

It seems unnecessary to create a font that I need the hDC
