## Detailed Description

A style sheet maps symbolic names to absolute values.

Ipe documents can use symbolic attributes, such as 'normal', 'fat', or 'thin' for line thickness, or 'red', 'navy', 'turquoise' for color. The mapping to an absolute pen thickness or RGB value is performed by a StyleSheet.

Style sheets are always included when the document is saved, so that an Ipe document is self-contained.

The built-in standard style sheet is minimal, and only needed to provide sane fallbacks for all the "normal" settings.

## Constructor & Destructor Documentation

## ◆ StyleSheet()

StyleSheet::StyleSheet | ( |  | ) |

The default constructor creates an empty style sheet.

References ipe::EDefaultCap, ipe::EDefaultJoin, and ipe::EDefaultRule.

## Member Function Documentation

## ◆ standard()

StyleSheet * StyleSheet::standard | ( |  | ) |
| static

Create standard built-in style sheet.

References ipe::ImlParser::parseStyleSheet().

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

## ◆ addSymbol()

void StyleSheet::addSymbol | ( | Attribute | name,
|  | const Symbol & | symbol
| ) |  |

Add a symbol object.

References ipe::Attribute::index(), and ipe::Attribute::isSymbolic().

Referenced by ipe::ImlParser::parseStyle().

## ◆ findSymbol()

const Symbol * StyleSheet::findSymbol | ( | Attribute | attr | ) | const

Find a symbol object with given name.

If attr is not symbolic or if the symbol doesn't exist, returns 0.

References ipe::Attribute::index(), and ipe::Attribute::isSymbolic().

## ◆ addGradient()

void StyleSheet::addGradient | ( | Attribute | name,
|  | const Gradient & | s
| ) |  |

Add gradient to this style sheet.

References ipe::Attribute::index(), and ipe::Attribute::isSymbolic().

Referenced by ipe::ImlParser::parseStyle().

## ◆ findGradient()

const Gradient * StyleSheet::findGradient | ( | Attribute | sym | ) | const

Find gradient in style sheet cascade.

References ipe::Attribute::index(), and ipe::Attribute::isSymbolic().

## ◆ addTiling()

void StyleSheet::addTiling | ( | Attribute | name,
|  | const Tiling & | s
| ) |  |

Add tiling to this style sheet.

References ipe::Attribute::index(), and ipe::Attribute::isSymbolic().

Referenced by ipe::ImlParser::parseStyle().

## ◆ findTiling()

const Tiling * StyleSheet::findTiling | ( | Attribute | sym | ) | const

Find tiling in style sheet cascade.

References ipe::Attribute::index(), and ipe::Attribute::isSymbolic().

## ◆ addEffect()

void StyleSheet::addEffect | ( | Attribute | name,
|  | const Effect & | e
| ) |  |

References ipe::Attribute::index(), and ipe::Attribute::isSymbolic().

Referenced by ipe::ImlParser::parseStyle().

## ◆ findEffect()

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

References ipe::Attribute::index(), and ipe::Attribute::isSymbolic().

## ◆ add()

void StyleSheet::add | ( | Kind | kind,
|  | Attribute | name,
|  | Attribute | value
| ) |  |

Add an attribute.

Does nothing if name is not symbolic.

References ipe::Attribute::index(), and ipe::Attribute::isSymbolic().

Referenced by ipe::ImlParser::parseStyle().

## ◆ has()

bool StyleSheet::has | ( | Kind | kind,
|  | Attribute | sym
| ) |  | const

Check whether symbolic attribute is defined.

This method also works for ESymbol, EGradient, ETiling, and EEffect.

Returns true if sym is not symbolic.

References ipe::EEffect, ipe::EGradient, ipe::ESymbol, ipe::ETiling, ipe::Attribute::index(), and ipe::Attribute::isSymbolic().

## ◆ find()

Attribute StyleSheet::find | ( | Kind | kind,
|  | Attribute | sym
| ) |  | const

Find a symbolic attribute.

If sym is not symbolic, returns sym itself. If sym cannot be found, returns the "undefined" attribute. In all other cases, the returned attribute is guaranteed to be absolute.

References ipe::Attribute::index(), ipe::Attribute::isSymbolic(), and ipe::Attribute::UNDEFINED().

## ◆ remove()

void StyleSheet::remove | ( | Kind | kind,
|  | Attribute | sym
| ) |  |

Removes definition for a symbolic attribute from this stylesheet.

This method also works for ESymbol, EGradient, ETiling, and EEffect. It is okay if the symbolic attribute is not defined in the stylesheet, nothing happens in this case.

References ipe::EEffect, ipe::EGradient, ipe::ESymbol, ipe::ETiling, and ipe::Attribute::index().

## ◆ saveAsXml()

void StyleSheet::saveAsXml | ( | Stream & | stream,
|  | bool | saveBitmaps = `false`
| ) |  | const

Save style sheet in XML format.

## ◆ allNames()

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

Return all symbolic names in the style sheet cascade.

Names are simply appended from top to bottom of the cascade. Names are inserted only once.
