procedure TP_GlobalIgnoreClass (IgnClass:TClass);

This procedure puts a class on a global ignore list, so that all objects of this type or of types descending from this type won't be translated by TranslateProperties() or TranslateComponent(). For instance, it is not very useful to have TFont objects translated, and therefore this line would make a lot of sense in most applications:

TP_GlobalIgnoreClass (TFont);

A good place to put this line is in the .dpr file. See the Section called Sample.dpr in the appendix called "Hello, World" source code> for further information.
