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-Schriften 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.

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.

const sal_IntPtr* FontList::GetSizeAry( const FontMetric& rFontMetric ) const;
|
|
|
|
This method returns the available sizes for the given font.
|
|
If it is a scalable font, 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.
