class TGPicture: public TObject, public TRefCnt
TGPicture & TGPicturePool The TGPicture class implements pictures and icons used in the different GUI elements and widgets. The TGPicturePool class implements a TGPicture cache. TGPictures are created, managed and destroyed by the TGPicturePool.

Function documentation
TGPicture(const char* name, Pixmap_t pxmap, Pixmap_t mask = 0)
ctor. Important: both pixmaps pxmap and mask must be unique (not shared)
const char * HashName(const char* name, Int_t width, Int_t height)
Static function returning a unique name used to look up a picture.
The unique name has the form "name__widthxheight".
TGSelectedPicture& operator=(const TGPicture& )
