Superclasses | Creation | Properties | Methods | Version History

The IDLffLangCat class is used to find and load an XML language catalog. A language catalog is composed of key names and key values. The key value of the specified key name can be retrieved to support internationalization. For example:

<KEY NAME='Menu:File:Open'>Open...</KEY>

in an English language catalog would appear as the following in a French language catalog:

<KEY NAME='Menu:File:Open'>Ouvrir...</KEY>

By handling files that contain keys and values like these, the IDLffLangCat class supports internationalization of user interfaces and other applications that need to display the same strings in more than one language.

The language catalogs included with IDL are in the <IDL_DIR>/resource/langcat directory and end in a .cat extension. You can use other catalogs, but all catalogs must end with the .cat extension.

Note

The IDLffLangCat class supports catalog files written in 8-bit Latin alphabet languages. Also, you must have the corresponding fonts installed on your machine before you can use a particular language.

Note
