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.

◆ Cascade() [2/2]

Cascade::Cascade ( const Cascade & rhs)

Copy constructor.

References count().

◆ ~Cascade()

Cascade::~Cascade ( )

Destructor.

Member Function Documentation

◆ operator=()

Cascade & Cascade::operator= ( const Cascade & rhs)

Assignment operator.

References count().

◆ count()

int ipe::Cascade::count ( ) const
inline

◆ sheet() [1/2]

StyleSheet * ipe::Cascade::sheet ( int index)
inline

Return StyleSheet at index.

Referenced by insert().

◆ sheet() [2/2]

const StyleSheet * ipe::Cascade::sheet ( int index) const
inline

Return StyleSheet at index.

◆ insert()

void Cascade::insert ( int index,
StyleSheet * sheet )

Insert a style sheet into the cascade.

Takes ownership of sheet.

References sheet().

Referenced by ipe::Document::Document(), and ipe::ImlParser::parseDocument().

◆ remove()

void Cascade::remove ( int index)

Remove a style sheet from the cascade.

The old sheet is deleted.

◆ saveAsXml()

void Cascade::saveAsXml ( Stream & stream) const

References count().

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

◆ has()

bool Cascade::has ( Kind kind,
Attribute sym ) const

References count(), and has().

Referenced by allNames(), findDefinition(), and has().

◆ find()

Attribute Cascade::find ( Kind kind,
Attribute sym ) const

◆ findSymbol()

const Symbol * Cascade::findSymbol ( Attribute sym) const

◆ findGradient()

const Gradient * Cascade::findGradient ( Attribute sym) const

◆ findTiling()

const Tiling * Cascade::findTiling ( Attribute sym) const

◆ findEffect()

const Effect * Cascade::findEffect ( Attribute sym) const

References count().

Referenced by ipe::PdfWriter::createPageView().

◆ findLayout()

const Layout * Cascade::findLayout ( ) const

◆ findTextPadding()

const TextPadding * Cascade::findTextPadding ( ) const

Find text padding (for text bbox computation).

References count().

Referenced by ipe::BBoxPainter::doDrawText().

◆ findTitleStyle()

const StyleSheet::TitleStyle * Cascade::findTitleStyle ( ) const

Get style of page titles (or 0 if none defined).

References count().

Referenced by ipe::Page::applyTitleStyle().

◆ findPageNumberStyle()

const StyleSheet::PageNumberStyle * Cascade::findPageNumberStyle ( ) const

Return style of page numbering (or 0 if none defined).

References count().

Referenced by ipe::Latex::addPageNumber().

◆ findPreamble()

String Cascade::findPreamble ( ) const

Return total LaTeX preamble (of the whole cascade).

References count().

Referenced by ipe::Latex::createLatexSource().

◆ lineCap()

TLineCap Cascade::lineCap ( ) const

◆ lineJoin()

TLineJoin Cascade::lineJoin ( ) const

◆ fillRule()

TFillRule Cascade::fillRule ( ) const

◆ allNames()

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

◆ 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.
