Description
============

class FontList

This class manages all fonts which can be display on one or two output devices.
Additionally, this class offers methods for generating the StyleName from
bold and italics or the missing attributes from a StyleName.
Furthermore, this class can handle synthetically reproduced fonts.
It also works with several standard controls and standard menus.

--------------------------------------------------------------------------

FontList::FontList( OutputDevice* pDevice, OutputDevice* pDevice2 = NULL,
                    bool bAll = true );

Constructor of the FontList class. 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. This string should be displayed to the user.

--------------------------------------------------------------------------

FontMetric FontList::Get( const String& rName, const String& rStyleName ) const;

This method search a FontMetric for the given name and the given style name.
The Stylename can also be a synthetic one.
In that case the relevant FontMetric fields will be set.
If a StyleName is provided, a FontMetric structure without a Stylename can be
returned. To get a representation of the StyleName for displaying it to the user,
call GetStyleName() on this FontMetric structure.

FontList::GetStyleName()

--------------------------------------------------------------------------

FontMetric FontList::Get( const String& rName, FontWeight eWeight,
                        FontItalic eItalic ) const;

This method search a FontMetric structure for a provided name and styles.
This method can also return a FontMetric without a Stylename.
To get a representation of the StyleName to be presented to the user
call GetStyleName() with this FontMetric.

FontList::GetStyleName()

--------------------------------------------------------------------------

static const int* FontList::GetStdSizeAry();

This method returns the available sizes for the given font.
As all fonts are scalable, standard sizes are returned.
The array contains the heights of the font in tenth (1/10) point.
The last value of the array is 0.
The returned array will destroyed by the FontList.
You should thus not reference the array after the next method call on the
FontList.
