view mde/gui/widget/miscContent.d @ 128:41582439a42b
Added support for dynamic EnumContent loading and saving, with translation loading.
WMScreen.init removed; code moved to this() since class is now created by main() instead of a static this().
Fix for SwitchWidget not passing events. Still some resizing bugs evident in SwitchWidget :-(
