Last change on this file since 12771 was 3904, checked in by mkommend, 14 years ago

Added SetEnabledStateOfControls as protected virtual method in !View. Therefore the overloading of OnReadOnlyChanged and OnLockedChanged got obsolete in most views, because the method got called in the !View respectively ContentView. (ticket #1021)
