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.
