The relevant fonts will be queried from +the OutputDevice. The OutputDevice needs to exist as long as the FontList +class exists. Optionally, a second output device can be given in order to, +e.g., manage the fonts from both, a printer and a screen in a single FontList +and thus also give FontMenus the fonts if both OutputDevices. +The pDevice2 needs to exist as long as the FontList class exists. + +The OutputDevice given first should be the preferred one. This is usually +the printer. Because if two different device fonts (one for the printer and +one for the screen) exist, the ones from the "pDevice" are preferred. + +The third parameter governs whether only scalable or all fonts shall be queried. +With sal_True bitmap fonts will also be queried. +With sal_False vectorized and scalable fonts will be queried. + +-------------------------------------------------------------------------- + +String FontList::GetStyleName( const FontMetric& rFontMetric ) const; + +This method returns the StyleName of a FontMetric. +If no StyleName is set, a name will be generated from the set attributes. + +-------------------------------------------------------------------------- + +OUString FontList::GetFontMapText( const FontMetric& rFontMetric ) const; + +This method returns a Matchstring which indicates the problem that could +arise when using a font.
