Member Function Documentation

GetCharWidth()

JSize JXFontManager::GetCharWidth ( const JFontID  id, const JUtf8Character &  c  )

overrideprotectedvirtual

Implements JFontManager.

GetFontNames()

void JXFontManager::GetFontNames ( JPtrArray< JString > *  fontNames )

overridevirtual

Implements JFontManager.

GetFontSizes()

bool JXFontManager::GetFontSizes ( const JString &  name, JSize *  minSize, JSize *  maxSize, JArray< JSize > *  sizeList  )

overridevirtual

If all font sizes are supported (e.g. TrueType), returns reasonable min and max, and empty sizeList.

Returns false if there is no font with the specified name.

Implements JFontManager.

GetLineHeight()

JSize JXFontManager::GetLineHeight ( const JFontID  id, const JSize  size, const JFontStyle &  style, JCoordinate *  ascent, JCoordinate *  descent  )

overrideprotectedvirtual

Implements JFontManager.

GetMonospaceFontNames()

void JXFontManager::GetMonospaceFontNames ( JPtrArray< JString > *  fontNames )

overridevirtual

Implements JFontManager.

GetStringWidth()

JSize JXFontManager::GetStringWidth ( const JFontID  id, const JString &  str  )

overrideprotectedvirtual

Implements JFontManager.

GetSubstituteFontName()

bool JXFontManager::GetSubstituteFontName ( const JFont &  f, const JUtf8Character &  c, JString *  name  )

overrideprotectedvirtual

Implements JFontManager.

GetXFont()

bool JXFontManager::GetXFont	(	const JString &	xFontStr,
		JFont **	font
	)

For X Windows only: pass in complete string from XListFonts().

Caller must jdelete the returned object.

GetXFontInfo()

JXFontManager::XFont JXFontManager::GetXFontInfo ( const JFontID  id )

inline

GetXFontNames()

void JXFontManager::GetXFontNames	(	const JRegex &	regex,
		JPtrArray< JString > *	fontNames,
		const std::function< std::weak_ordering(JString *const &, JString *const &)> *	compare = nullptr
	)

This provides raw output from XListFonts(). For example, ^[0-9]x[0-9]+$ would yield a list of clean, monospace fonts.

If compare is nullptr, we use JCompareStringsCaseInsensitive().

HasGlyphForCharacter()

bool JXFontManager::HasGlyphForCharacter ( const JFontID  id, const JUtf8Character &  c  )

overrideprotectedvirtual

Implements JFontManager.

Init()

void JXFontManager::Init ( )

static

IsExact()

bool JXFontManager::IsExact ( const JFontID  id )

overrideprotectedvirtual

Implements JFontManager.

Preload()

void JXFontManager::Preload ( const JFontID  id )

inline
