show when variables are complex in workspace view (bug #40445) * octave-qt-link.h, octave-qt-link.cc (octave_qt_link::do_set_workspace, octave_qt_link::set_workspace_signal): Pass complex info in set_workspace_signal. * main-window.cc (main_window::construct_octave_qt_link): Update set_workspace_signal signal to set_workspace slot connection. * workspace-model.h, workspace-model.cc (workspace_model::data): Display whether variables are complex in "Storage Class" column. (workspace_model::_complex_flags): New data member. (workspace_model::set_workspace): Store _complex_flags. (workspace_model::clear_data): Clear _complex_flags. * workspace-element.h (workspace_element::xcomplex_flags): New data member. * symtab.cc (symbol_table::do_workspace_info): Also stash complex flag.
