annotate libgui/graphics/Container.h @ 27303:07b330708e3c
use Qt signals for interpreter callbacks in Qt graphics toolkit
* Backend.h, Backend.cc (Backend::m_interpreter): New data member.
(Backend::createObject): Pass pointer to invoking Backend object in
signal argument list.
(Backend::interpreter_event): New slots. Access interpreter
event_manager to post interpreter callbacks events here.
* ObjectFactory.h, ObjectFactory.cc (ObjectFactory::createObject): New
arg, backend. Connect interpreter_event signal from newly created
object to interpreter_event slot in backend object.
* __init_qt__.cc (__init__): Pass interpreter to Backend constructor.
* module.mk (OCTAVE_GUI_GRAPHICS_MOC): New files, moc-Canvas.cc and
moc-Container.cc.
* Object.h (Object::interpreter_event): New signals.
* Canvas.h, Canvas.cc (Canvas::interprter_event): New signals.
(Canvas::canvasMouseReleaseEvent): Emit interpreter_event signal
instead of accessing interpreter event_manager object directly here.
* GLCanvas.cc (GLCanvas::do_print): Emit interpreter_event signal
instead of accessing interpreter event_manager object directly here.
* Container.h, Container.cc (Container::interpreter_event):
New signals.
(Container::canvas): Forward Canvas interpreter_event signals to
Container interpreter_event signals.
* ButtonGroup.cc (ButtonGroup::ButtonGroup) Forward Container
interpreter_event signals to the ButtonGroup interpreter_event
signal. Since ButtonGroup is derived from Object, this connection and
the one made by ObjectFactory::createObject has the effect of passing
the interpreter_event signal up to the Backend interpreter_event slot.
* Figure.cc (Figure::Figure): Likewise, for Figure.
* Panel.cc (Panel::Panel): Likewise, for Panel.
