TLogicalFont Class Reference

class TLogicalFont

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 Enumerations 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.

Enumerators

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.

Enumerators

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.
