Member Function Documentation

◆ Draw() [1/2]

void TGPicture::Draw ( Option_t * option = "" )

inlineprotectedvirtual

Default Draw method for all objects.

Reimplemented from TObject.

Definition at line 57 of file TGPicture.h.

◆ Draw() [2/2]

void TGPicture::Draw	(	Handle_t	id,
		GContext_t	gc,

◆ GetMask()

Pixmap_t TGPicture::GetMask ( ) const

inline

Definition at line 66 of file TGPicture.h.

◆ GetName()

const char* TGPicture::GetName ( ) const

inlinevirtual

Returns name of object.

This default method returns the class name. Classes that give objects a name should override this method.

Reimplemented from TObject.

Definition at line 62 of file TGPicture.h.

◆ GetPicture()

Pixmap_t TGPicture::GetPicture ( ) const

inline

Definition at line 65 of file TGPicture.h.

◆ GetWidth()

UInt_t TGPicture::GetWidth ( ) const

inline

Definition at line 63 of file TGPicture.h.

◆ Hash()

ULong_t TGPicture::Hash ( ) const

inlinevirtual

Return hash value for this object.

Note: If this routine is overloaded in a derived class, this derived class should also add

ROOT::CallRecursiveRemoveIfNeeded(*this)

Otherwise, when RecursiveRemove is called (by ~TObject or example) for this type of object, the transversal of THashList and THashTable containers will will have to be done without call Hash (and hence be linear rather than logarithmic complexity). You will also see warnings like

Error in <ROOT::Internal::TCheckHashRecursiveRemoveConsistency::CheckRecursiveRemove>: The class SomeName overrides TObject::Hash but does not call TROOT::RecursiveRemove in its destructor.

Reimplemented from TObject.

Definition at line 68 of file TGPicture.h.

◆ HashName()

const char * TGPicture::HashName	(	const char *	name,
		Int_t	width,
		Int_t	height
	)

static

Static function returning a unique name used to look up a picture.

The unique name has the form "name__widthxheight".

Definition at line 375 of file TGPicture.cxx.

◆ IsScaled()

Bool_t TGPicture::IsScaled ( ) const

inline

Definition at line 67 of file TGPicture.h.

◆ Print()

void TGPicture::Print ( Option_t * option = "" ) const

virtual

Print picture info.
