AddDrawable()

template<class DRAWABLE >

auto& ROOT::Experimental::TPadBase::AddDrawable ( std::unique_ptr< DRAWABLE > &&  uPtr )

inlineprivate

Adds a DRAWABLE to fPrimitives, returning the drawing options as given by DRAWABLE::Options().

Definition at line 60 of file TPad.hxx.

Divide()

std::vector< std::vector< ROOT::Experimental::TPad * > > ROOT::Experimental::TPadBase::Divide	(	int	nHoriz,
		int	nVert,
		const TPadExtent &	padding = {}
	)

Divide this pad into a grid of subpad with padding in between.

Parameters

nHoriz	Number of horizontal pads.
nVert	Number of vertical pads.
padding	Padding between pads.

Returns

vector of vector (ret[x][y]) of created pads.

Definition at line 28 of file TPad.cxx.

Draw() [1/3]

template<class T >

auto& ROOT::Experimental::TPadBase::Draw ( const std::shared_ptr< T > &  what )

inline

Add something to be painted.

The pad observes what's lifetime through a weak pointer.

Definition at line 84 of file TPad.hxx.

Draw() [2/3]

template<class T >

auto& ROOT::Experimental::TPadBase::Draw ( std::unique_ptr< T > &&  what )

inline

Add something to be painted. The pad claims ownership.

Definition at line 92 of file TPad.hxx.

Draw() [3/3]

template<class T , class = typename std::enable_if<!ROOT::TypeTraits::IsSmartOrDumbPtr<T>::value>::type>

auto& ROOT::Experimental::TPadBase::Draw ( const T &  what )

inline

Add a copy of something to be painted.

virtual const TCanvas& ROOT::Experimental::TPadBase::GetCanvas ( ) const

pure virtual

Access to the top-most canvas, if any (const version).

Implemented in ROOT::Experimental::TPad, and ROOT::Experimental::TCanvas.

GetCanvas() [2/2]

virtual TCanvas& ROOT::Experimental::TPadBase::GetCanvas ( )

pure virtual

Access to the top-most canvas, if any (non-const version).

Implemented in ROOT::Experimental::TPad, and ROOT::Experimental::TCanvas.
