eliminate some connections to parent objects in octave_dock_widget classes This is another change aimed at removing connections to parent objects and ultimately, to avoid needing to store references to base_qobject in any widgets. * octave-dock-widget.h, octave-dock-widget.cc (octave_dock_widget::interpreter_event): Delete signals. (octave_dock_widget::octave_dock_widget): Don't connect interpreter_event signals to base_qobject slots. * file-editor-interface.h (file_editor_interface::interpreter_event): Declare signals here. * variable-editor.h (variable_editor::interpreter_event): Likewise. * main-window.cc (main_window::main_window): Make interpreter_event connections for the editor. * octave-qobject.h, octave-qobject.cc (base_qobject::connect_interpreter_events): New function. (base_qobject::variable_editor_widget): Make interpreter_event connections here. * QTerminal.h, QTerminal.cc (QTerminal::create, QTerminal::construct): Eliminate MAIN_WIN argument. Change all callers. (QTerminal::construct): Don't make connections to main window signals or slots here. (QTerminal::request_edit_mfile_signal, QTerminal::request_open_file_signal, QTerminal::set_screen_size_signal, QTerminal::clear_command_window_request): New signals. * QUnixTerminalImpl.h, QUnixTerminalImpl.cpp (QUnixTerminalImpl::initialize, QUnixTerminalImpl::QUnixTerminalImpl): Eliminate MAIN_WIN argument. Change all callers. (QUnixTerminalImpl::initialize): Don't make connections to main window signals or slots here. * QWinTerminalImpl.h, QWinTerminalImpl.cpp (QWinTerminalImpl::QWinTerminalImpl): Eliminate MAIN_WIN argument. Change all callers. Don't make connections to main window slot here. (QWinTerminalImpl::set_screen_size_signal): Delete. Signal moved to QTerminal base class. * terminal-dock-widget.h, terminal-dock-widget.cc (terminal_dock_widget::get_qteriminal, terminal_dock_widget::get_command_widget): New functions. (terminal_dock_widget::terminal_dock_widget): Don't make connections to main window signals or slots here. * main-window.h, main-window.cc (main_window::main_window): Make connections from terminal widgets to main window here.
