## 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.

## Member Function Documentation

## operator=()

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

Assignment operator.

References count().

## count()

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

inline

Return number of style sheets.

Referenced by Cascade(), and operator=().

## sheet() [1/2]

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

inline

Return StyleSheet at index.

## 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.

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()

## findEffect()

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

## findLayout()

const Layout * Cascade::findLayout | ( |  | ) | const

Find page layout (such as text margins).

Referenced by ipe::PanTool::draw(), and ipe::Thumbnail::Thumbnail().

## findTextPadding()

const TextPadding * Cascade::findTextPadding | ( |  | ) | const

Find text padding (for text bbox computation).

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

## findTitleStyle()

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

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

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

## findPageNumberStyle()

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

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

## findPreamble()

String Cascade::findPreamble | ( |  | ) | const

Return total LaTeX preamble (of the whole cascade).

## 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.
