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)
void Draw(Handle_t id, GContext_t gc, Int_t x, Int_t y) const
 Draw a picture.
 Delete picture object.
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".
void Print(Option_t* option = "") const
 Print picture info.
TGPicture(const char* name, Bool_t scaled = kFALSE)
TGPicture(const char* name, Pixmap_t pxmap, Pixmap_t mask = 0)
void Draw(Option_t* = "")
 override default of TObject
{ MayNotUse("Draw(Option_t*)"); }
const char * GetName() const
{ return fName; }
UInt_t GetWidth() const
{ return fAttributes.fWidth; }
UInt_t GetHeight() const
{ return fAttributes.fHeight; }
Pixmap_t GetPicture() const
{ return fPic; }
Pixmap_t GetMask() const
{ return fMask; }
Bool_t IsScaled() const
{ return fScaled; }
ULong_t Hash() const
{ return fName.Hash(); }
