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.

~TGPicture()

 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(); }
