## Detailed Description

Abstraction of translations discovery and loading.

This interface makes it possible to override wxWidgets' default catalogs loading mechanism and load MO files from locations other than the filesystem (e.g. embed them in executable).

Implementations must implement the LoadCatalog() method.

  wxFileTranslationsLoader, wxResourceTranslationsLoader

Since:
  2.9.1

## Constructor & Destructor Documentation

wxTranslationsLoader::wxTranslationsLoader | ( |  | ) | `[inline]`

Constructor.

## Member Function Documentation

virtual wxArrayString wxTranslationsLoader::GetAvailableTranslations | ( | const wxString & | domain | ) | const`[pure virtual]`

Implements wxTranslations::GetAvailableTranslations().

virtual wxMsgCatalog* wxTranslationsLoader::LoadCatalog | ( | const wxString & | domain,
|  | const wxString & | lang |
| ) |  |  | `[pure virtual]`

Called to load requested catalog.

If the catalog is found, LoadCatalog() should create wxMsgCatalog instance with its data and return it. The caller will take ownership of the catalog.

Parameters:

  | domain | Domain to load.
  | lang | Language to look for. This is "canonical name" (see wxLocale::GetCanonicalName()), i.e. ISO 639 code, possibly combined with country code or additional modifiers (e.g. "fr", "en_GB" or "ca@valencia").

Returns:
  Loaded catalog or NULL on failure.
