Function documentation

~TGLFontManager()

 Destructor.

void RegisterFont(Int_t size, Int_t fileID, TGLFont::EMode mode, TGLFont &out)

 Provide font with given size, file and FTGL class.

void RegisterFont(Int_t size, const Text_t* name, TGLFont::EMode mode, TGLFont &out)

 Get mapping from ttf id to font names. Table taken from TTF.cxx.

void ReleaseFont(TGLFont& font)

 Release font with given attributes. Returns false if font has
 not been found in the managers font set.

TObjArray* GetFontFileArray()

Int_t GetFontSize(Float_t ds, Int_t min = -1, Int_t max = -1)

 Get availabe font size.

const char* GetFontNameFromId(Int_t )

void InitStatics()

 Create a list of available font files and allowed font sizes.

void ClearFontTrash()

 Delete FTFFont objects registered for destruction.

TGLFont& operator=(const TGLFontManager& )
