IDLgrBuffer::GetFontnames

IDLgrBuffer::GetFontnames

The IDLgrBuffer::GetFontnames function method returns the list of available fonts that can be used in IDLgrFont objects. This method will only return the names of the available TrueType fonts. Hershey fonts will not be returned.

Syntax


Result = Obj->[IDLgrBuffer::]GetFontnames( FamilyName[, IDL_FONTS={0 | 1 | 2 }] [, STYLES=string] )

Return Value


Returns the list of available fonts that can be used in IDLgrFont objects.

Arguments


FamilyName

A string representing the name of the font family to which all of the returned fonts must belong. The string may be a fully specified family name—such as “Helvetica”. You can use both “*” and “?” as wildcard characters, matching any number of characters or one character respectively. To return all available family names, use “*”.

Keywords


IDL_FONTS

Set this keyword to specify where to search for fonts that IDL may use. Set IDL_FONT to 1 to select only fonts installed by IDL and to 2 to select only fonts detected in the host operating system. The default value is 0, specifying that both IDL and operating system fonts should be returned.

STYLES

Set this keyword to a string specifying the styles that are to be matched by the returned font names. You can set STYLES to a fully specified style string, such as “Bold Italic”. If you set STYLES to an empty string, ' ', only fontnames without style modifiers will be returned. You can use both “*” and “?” as wildcard characters, matching any number of characters or one character respectively. The default value is the string, “*”, which returns all fontnames containing the FamilyName argument, with or without style modifiers.
