/**
 * This is the main view class for Lokalize Editor.
 * Most of the non-menu, non-toolbar, non-statusbar,
 * and non-dockview editing GUI code should go here.
 *
 * There are several ways (for views) to modify current msg:
 * -modify KTextEdit and changes will be applied to catalog automatically (plus you need to care of fuzzy indication etc)
 * -modify catalog directly, then call EditorWindow::gotoEntry slot
 * I used both :)
