adding language selection to Preferences dialog
|Assignee:||J. Templ||% Done:|
In order to support multiple languages the 'Preferences' dialog (Host/Rsrc/Prefs.odc) needs to be extended with a language selection.
A proposal by Helmut Zinn for the changes exists in CPC 1.7 rc6.
Refers to CPC 1.7 change list number 52.
language selection added to 'Preferences' dialog. Refs: #89.
As proposed by Helmut Zinn in CPC 1.7 rc6 with minor adaptations:
1. Any reference to CPC packages removed. Note that any module that needs to be
informed about language selection events can use Dialog.RegisterLangNotifier.
2. Language selection without a special notifier that switches the language immediately.
Instead, the language selection is applied when pressing the OK button.
