Class TLogicalFont

class TLogicalFont;

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).
