AddFromStyleFile()

bool TDrawingOptsReader::AddFromStyleFile

(

std::string_view

filename

)

Adds attributes specified in filename to those already existing in fAttrs.

Overwrites values for attributes that already exist in attrs!

Returns

true on success, false if the file cannot be found or the syntax is wrong. Prints an error if the syntax is wrong (but not if the file does not exist).

Parse() [1/3]

TColor ROOT::Experimental::Internal::TDrawingOptsReader::Parse ( std::string_view  attr, const TColor &  deflt, std::vector< std::string_view >  = {}  )

double ROOT::Experimental::Internal::TDrawingOptsReader::Parse ( std::string_view  attr, double  deflt, std::vector< std::string_view >  = {}  )

ParseColor()

ROOT::Experimental::TColor TDrawingOptsReader::ParseColor	(	std::string_view	attr,
		const TColor &	deflt
	)

Parse a TColor from attr's value.

Colors can be specified as RGBA (red green blue alpha) or RRGGBBAA: #fa7f #ffa07bff For all predefined colors in TColor, colors can be specified as name without leading 'k', e.g. red for TColor::kRed. Prints an error and returns TColor::kBlack if the attribute string cannot be parsed or if the attribute has no entry in fAttrs.

Definition at line 41 of file TDrawingOptsReader.cxx.

ParseFP()

double TDrawingOptsReader::ParseFP	(	std::string_view	attr,
		double	deflt
	)

Parse a floating point attribute.

Returns 0. and prints an error if the attribute string cannot be parsed as a floating point number. Prints an error if the attribute has no entry in fAttrs.

Definition at line 56 of file TDrawingOptsReader.cxx.

ParseInt()

long long TDrawingOptsReader::ParseInt	(	std::string_view	attr,
		long long	deflt,
		std::vector< std::string_view >	opts = {}
	)

Parse an integer attribute, or if opts is given, return the index of the string from the options file in opts.

Returns 0 (and prints an error) if the string cannot be found in opts, or if the integer cannot be parsed or if the attribute has no entry in fAttrs.

Definition at line 49 of file TDrawingOptsReader.cxx.

ReadDefaults()

TDrawingOptsReader::Attrs_t TDrawingOptsReader::ReadDefaults ( )

static

Reads the attribute config values from .rootstylerc.

If the style entry is not found there, tries ~/.rootstylerc and finally $ROOTSYS/system.rootstylerc.
