imjslideshow is written in Java and uses the internationalization capabilities of Java.

All text are generated with java.util.ResourceBundle. If formatting is needed, then java.text.MessageFormat is used.

A resource-bundle is created for every package with at least one class, that needs localization.

The RessourceBundles for imjslideshow are located in the folder net/sourceforge/imjSlideshow/l10n. The name of the resource-bundle is the package-name without the leading net.sourceforge.imjSlideshow, with an underscore in place of dots and with the extension "properties".
Example: Classes in the package "net.sourceforge.imjslideshow.ui.dnd" uses the resource-bundle "ui_dnd.properties" in the folder "net/sourceforge/imjslideshow/l10n".

The name of an item within the resource-bundle is derived from the name of the class.
Example: "SlideshowException.Title" in base.properties is used in the class net.sourceforge.imjSlideshow.base.SlideshowException.

For a given country or language all properties-files must be copied and named according the naming-convention of resource-bundles with the country-code and if needed with the language-code.
Example: The resource-bundle ui_dnd.properties for german is ui_dnd_de.properties.

For details look at the java documentation.

The mnemonic-key of an action must not be set in a separate text. It can be signaled with a "&" in the name of the action. This is used in the action-texts in ui.properties.
Example: "SlideshowV.File.New.Name=&new Slideshow" defines "n" as the mnemonic-key of the new-action of the slideshow in the English localization.

"shift", "alt", "meta" and "alt graph" can be used to define the accelerator-key of an action. This is used in the action-texts in ui.properties.
Example: "SlideshowV.File.New.Accelerator=n shift alt" defines the "n"-key with hold down the "shift"- and "alt"-key as the accelerator-key of the new-action of the slideshow in the English localization.
