eliminate global access to Octave resources in qt graphics classes Provide reference to base_qobject to qt graphics classes to eliminate need for accessing it through a global variable. * qt-graphics-toolkit.h, qt-graphics-toolkit.cc (qt_graphics_toolkit::m_octave_qobj): New member variable. (qt_graphics_toolkit::qt_graphics_toolkit): Accept reference to base_qobject as argument. (qt_graphics_toolkit::create_object): Pass m_octave_qobj to create functions for individual graphics objects. * __init_qt__.cc (__init__): Temporarily access base_qobject by calling octave::base_qobject::the_octave_qobject. Pass it to qt_graphics_toolkit constructor. * BaseControl.h, BaseControl.cc, ButtonControl.h, ButtonControl.cc, ButtonGroup.h, ButtonGroup.cc, Canvas.h, Canvas.cc, CheckBoxControl.h, CheckBoxControl.cc, Container.h, Container.cc, ContextMenu.h, ContextMenu.cc, EditControl.h, EditControl.cc, Figure.h, Figure.cc, GLCanvas.h, GLCanvas.cc, ListBoxControl.h, ListBoxControl.cc, Menu.h, Menu.cc, Panel.h, Panel.cc, PopupMenuControl.h, PopupMenuControl.cc, PushButtonControl.h, PushButtonControl.cc, PushTool.h, PushTool.cc, RadioButtonControl.h, RadioButtonControl.cc, SliderControl.h, SliderControl.cc, Table.h, Table.cc, TextControl.h, TextControl.cc, ToggleButtonControl.h, ToggleButtonControl.cc, ToggleTool.h, ToggleTool.cc, ToolBar.h, ToolBar.cc, ToolBarButton.h, ToolBarButton.cc, annotation-dialog.h, annotation-dialog.cc: Accept reference to base_qobject in create function and constructors for graphics objects. Eliminate global access to GUI resources.
