Get()

RStyle * RStyle::Get ( std::string_view  name )

static

Get the RStyle named name from the global style collection, or nullptr if that doesn't exist.

Definition at line 56 of file RStyle.cxx.

GetAttribute()

std::string RStyle::GetAttribute	(	const std::string &	attrName,
		const std::string &	className = {}
	)		const

Get the style value as a string, given an attribute name.

Strips leading "foo." from the name until the first entry in the style is found. E.g. if the default style has not entry for "Hist.1D.Fill.Color", the value might be initialized to the default style's entry for the more general "1D.Fill.Color". The className is the name of a CSS-style class, possibly overriding the generic attribute.
