class TGPicturePool: public TObject


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

TGPicturePool(const TGPicturePool& )
copy constructor
TGPicturePool& operator=(const TGPicturePool& )
assignment operator
const TGPicture * GetPicture(const char* name)
 Get a picture from the picture pool. Picture must be freed using
 TGPicturePool::FreePicture(). If picture is not found 0 is returned.
const TGPicture * GetPicture(const char *name, UInt_t new_width, UInt_t new_height)
 Get picture with specified size from pool (picture will be scaled if
 necessary). Picture must be freed using TGPicturePool::FreePicture(). If
 picture is not found 0 is returned.
const TGPicture * GetPicture(const char *name, Pixmap_t pxmap, Pixmap_t mask)
 Get picture with specified pixmap and mask from pool.
 Picture must be freed using TGPicturePool::FreePicture().
 If picture is not found 0 is returned.
const TGPicture * GetPicture(const char* name, char** xpm)
 Create picture from XPM data.
 Picture must be freed using TGPicturePool::FreePicture().
 If picture creation failed 0 is returned.
void FreePicture(const TGPicture* pic)
 Remove picture from cache if nobody is using it anymore.
~TGPicturePool()
 Delete picture cache.
void Print(Option_t* option = "") const
 List all pictures in the pool.
TGPicturePool(const TGPicturePool& )
const char * GetPath()
{ return fPath; }
