Change all uses. * octave-qt-link.h, octave-qt-link.cc (octave_qt_link::octave_qt_link): Call qRegisterMetaType for octave_value. (octave_qt_link::do_edit_variable): Rename from octave_qt_link::do_openvar. Change all uses. (edit_variable_signal): Rename from open_variable_signal. * variable-editor-model.h, variable-editor-model.cc (variable_editor_model::variable_editor_model): Also pass value. Change all uses. * variable-editor.h, variable-editor.cc (variable_editor::edit_variable): Also pass value. Change all uses. Align label at top of vbox layout. * octave-link.h, octave-link.cc (Fopenvar): Use DEFMETHOD. Get value from current scope and pass to octave_link::edit_variable. (octave_link::edit_variable): Rename from octave_link::openvar. Change all uses. (octave_link::do_edit_variable): Rename from octave_link::do_openvar. Change all uses.
