Detailed Description

A PangoFontset C++ wrapper class.

A Fontset represents a set of Font to use when rendering text. It is the result of resolving a FontDescription against a particular Context. It has operations for finding the component font for a particular Unicode character, and for finding a composite set of metrics for the entire fontset.

Member Typedef Documentation

typedef sigc::slot<bool, const Font&> Xfc::Pango::Fontset::ForeachSlot

Signature of the callback slot to be called for font in the fontset. Example: Method signature for ForeachSlot. bool method(const Font& font); // font: A Pango::font. // return true to stop the iteration.

Constructor & Destructor Documentation

Xfc::Pango::Fontset::Fontset (  PangoFontset *  fontset, bool  owns_reference = true )  [explicit, protected]

Construct a new Fontset from an existing PangoFontset. Parameters: fontset  A pointer to a PangoFontset. owns_reference  Set false if the initial reference count is floating, set true if it's not. The fontset can be a newly created PangoFontset or an existing PangoFontset. (see G::Object::Object).

Member Function Documentation

void Xfc::Pango::Fontset::foreach (  const ForeachSlot &  each  )

Iterates through all the fonts in the fontset, calling each for each one. Parameters: each  The callback slot. Returns: true to stops the iteration.

Pointer<Font> Xfc::Pango::Fontset::get_font (  unsigned int  wc  )  const

Returns the font in the fontset that contains the best glyph for the unicode character wc. Parameters: wc  A unicode character. Returns: A smart pointer to a Font.

Pointer<FontMetrics> Xfc::Pango::Fontset::get_metrics (   )  const

Get overall metric information for the fonts in the fontset. Returns: A smart pointer to a FontMetrics object.
