Detailed Description

Class managing a single graphics context and OSG GraphicsWindow.

Definition at line 39 of file WGEGraphicsWindow.h.

Constructor & Destructor Documentation

WGEGraphicsWindow::WGEGraphicsWindow	(	osg::ref_ptr< osg::Referenced >	wdata,
		int	x,
		int	y,
		int	width,
		int	height
	)

Default constructor.

Parameters

wdata	the WindowData instance for the widget to use as render widget. NULL on Mac!
x	X coordinate of widget where to create the context.
y	Y coordinate of widget where to create the context.
width	Width of the widget.
height	Height of the Widget.

Exceptions

WGEInitFailed thrown if initialization of graphics context or graphics window has failed.

Definition at line 31 of file WGEGraphicsWindow.cpp.

WGEGraphicsWindow::~WGEGraphicsWindow ( )

virtual

Destructor.

Definition at line 60 of file WGEGraphicsWindow.cpp.

void WGEGraphicsWindow::close ( )

virtual

Initiates a close event for this viewer.

It destroys the graphics context and invalidates the viewer. This should be called whenever a QT Widget closes to also free its OSG Viewer resources.

Reimplemented in WGEViewer.

Definition at line 112 of file WGEGraphicsWindow.cpp.

void WGEGraphicsWindow::createContext	(	int	x,
		int	y,
		int	width,
		int	height
	)

protected

Creates a new OpenGL context in the calling thread.

Needs to be called before any other OpenGL operation.

Parameters

x	X coordinate of widget where to create the context.
y	Y coordinate of widget where to create the context.
width	Width of the widget.
height	Height of the Widget.

osg::ref_ptr< osgViewer::GraphicsWindow > WGEGraphicsWindow::getGraphicsWindow ( )

Getter for m_GraphicsWindow.
