Use menu triggered signal instead of action triggered signal to rid cast. * file-editor.cc (file_editor::request_mru_open_file): Add QAction pointer as function argument. Remove sender() cast. (file_editor::construct): Connect request_mru_open_file slot to menu trigger signal instead of action trigger signals. * file-editor.h (file_editor : public file_editor_interface): Add QAction pointer as input to request_mru_open_file slot.
