Detailed Description

A cascade of style sheets.

The StyleSheets of a document cascade in the sense that a document can refer to several StyleSheets, which are arranged in a stack. A lookup is done from top to bottom, and returns as soon as a match is found. Ipe always appends the built-in "standard" style sheet at the bottom of the cascade.

Constructor & Destructor Documentation

Cascade() [1/2]

Cascade::Cascade

(

)

Create an empty cascade.

This does not add the standard style sheet.

References ipe::size().

Cascade() [2/2]

Cascade::Cascade

(

const Cascade &

rhs

)

Copy constructor.

References count().

~Cascade()

Cascade::~Cascade

(

)

Destructor.

allNames()

void Cascade::allNames	(	Kind	kind,
		AttributeSeq &	seq
	)		const

References ipe::Attribute::NORMAL().

Referenced by ipe::Document::runLatex().

findDefinition()

int Cascade::findDefinition	(	Kind	kind,
		Attribute	sym
	)		const

Find stylesheet defining the attribute.

This method goes through the cascade looking for a definition of the symbolic attribute sym. It returns the index of the stylesheet defining the attribute, or -1 if the attribute is not defined.

The method panics if sym is not symbolic. It also works for ESymbol, EGradient, ETiling, and EEffect.
