Detailed Description

Packages the attributes of a logical font.

These attributes include a UID (iFontId) and a category (iCategory), either of which can be used to identify a required system font. The possible values for the UID are defined in the UI variant's look and feel layer, so are not the same as the UID values that may be used to create a physical font.

An object of this class can be passed by any application to CEikonEnv::Font(), to return the closest matching system font (a CFont-derived object).

Member Enumeration Documentation

Enum TFontCategory

Logical font categories.

The font category specifies the type of font that is required. It can be specified as an alternative to the logical font UID. The physical fonts associated with these categories are specified in the LAF layer, so are UI variant-specific.

Enumerator	Value	Description
EView		The normal system font.
EButton		The font used in buttons.
EAnnotation		The font used for annotations. This is smaller than the normal font. For instance, it is used to draw the page number in some applications.
ETitle		The font used for titles.

Enum TFontStyle

Font styles.

Enumerator	Value	Description
ENormal		Normal style.
EBold		Bold.
EItalic		Italics.
EBoldItalic		Bold and italics.
ESuperscript		Superscript.
ESubscript		Subscript.
ELight		Light. This is the opposite of bold, i.e. a smaller than normal pen size is used to draw it.
ECustom		Custom font.
