Rather than trying to implement full i18n plural support, we just remove this failed attempt from the past. The fact is that to get proper support, we'd basically need to reimplement a Gettext-like plural definition syntax within our API, then ask people to write down this plural definition for their language, then to write every plural form… all this for custom units which only them will ever see! Moreover code investigation shows that the singular form was simply never used, and the plural form was always used (whatever the actual unit value displayed). As for the "identifier", this was a text which was never shown anywhere (except in the unit editor) and for all built-in units, as well as default unitrc units, it was equivalent to the English plural value. So we now just have a unique name which is the "long label" to be used everywhere in the GUI, and abbreviation will be basically the "short label". That's it. No useless (or worse, not actually usable because it was not generic internationalization) values anymore!

* @short_description: Some simple dialogs to enter a single int,
|
|
* double, string or boolean value.
|
|
* @see_also: #GimpSizeEntry, #GimpUnitMenu
|
|
*
|
|
* These functions provide simple dialogs for entering a single

|
* string, integer, double, boolean or pixel size value.
|
|
*
|
|
* They return a pointer to a #GtkDialog which has to be shown with
|
|
* gtk_widget_show() by the caller.
|
|
*
|
|
* The dialogs contain an entry widget for the kind of value they ask
|
|
* for and "OK" and "Cancel" buttons. On "Cancel", all query boxes
|
|
* except the boolean one silently destroy themselves. On "OK" the
|
|
* user defined callback function is called and returns the entered
|
|
* value.
