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 ( )


Member Function Documentation

◆ operator=()

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

Assignment operator.

References count().

◆ count()

int ipe::Cascade::count ( ) const

◆ sheet() [1/2]

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

Return StyleSheet at index.

Referenced by insert().

◆ sheet() [2/2]

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

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()

◆ 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).

◆ lineCap()

TLineCap Cascade::lineCap ( ) const

◆ lineJoin()

TLineJoin Cascade::lineJoin ( ) const

◆ fillRule()

◆ 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.
