ROOT::Experimental::TDrawingOptsBase< DERIVED > Class Template Reference

template<class DERIVED>
class ROOT::Experimental::TDrawingOptsBase< DERIVED >

Base class for drawing options.

Implements access to the default and the default's initialization from a config file.

Drawing options are made up of three kinds of primitives:

• TColor
• integer (long long)
• floating point (double) They register the primitives with their TCanvas, and then refer to the registered primitives. Upon destruction, the TDrawingOptsBase deregisters the use of its primitives with the TCanvas, which empties the respective slots in the tables of the TCanvas, unless other options reference the same primitives (through SameAs()), and until the last use has deregistered.

In derived classes (e.g. drawing options for the class MyFancyBox), declare attribute members as TDrawingAttrRef<TColor> fLineColor{*this, "MyFancyBoxLineColor", kRed}; The attribute's initial value will be taken from the current style or, if that has no setting for the attribute, from the argument passed to the constructor (kRed in the example above).
