static
virtual int vtkOpenGLContextBufferId::IsA ( const char *  name)
virtual

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkAbstractContextBufferId.

static vtkOpenGLContextBufferId* vtkOpenGLContextBufferId::SafeDownCast ( vtkObjectBase *  o)
static
virtual vtkObjectBase* vtkOpenGLContextBufferId::NewInstanceInternal ( ) const

Reimplemented from vtkAbstractContextBufferId.

vtkOpenGLContextBufferId* vtkOpenGLContextBufferId::NewInstance ( ) const
virtual void vtkOpenGLContextBufferId::PrintSelf ( ostream &  os,
vtkIndent  indent 
)
virtual

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkAbstractContextBufferId.

static vtkOpenGLContextBufferId* vtkOpenGLContextBufferId::New ( )
static

Creates a 2D Painter object.

virtual void vtkOpenGLContextBufferId::ReleaseGraphicsResources ( )
virtual

Release any graphics resources that are being consumed by this object.

Reimplemented from vtkAbstractContextBufferId.

virtual void vtkOpenGLContextBufferId::SetContext ( vtkRenderWindow *  context)
virtual

Set/Get the OpenGL context owning the texture object resource.

Implements vtkAbstractContextBufferId.

virtual vtkRenderWindow* vtkOpenGLContextBufferId::GetContext ( )
virtual

Set/Get the OpenGL context owning the texture object resource.

Implements vtkAbstractContextBufferId.

virtual bool vtkOpenGLContextBufferId::IsSupported ( )
virtual

Returns if the context supports the required extensions.

Precondition
context_is_set: this->GetContext()!=0

Implements vtkAbstractContextBufferId.

virtual void vtkOpenGLContextBufferId::Allocate ( )
virtual

Allocate the memory for at least Width*Height elements.

Precondition
positive_width: GetWidth()>0

virtual

Copy the contents of the current read buffer to the internal texture starting at lower left corner of the framebuffer (srcXmin,srcYmin).

Precondition
is_allocated: this->IsAllocated()

Implements vtkAbstractContextBufferId.

virtual vtkIdType vtkOpenGLContextBufferId::GetPickedItem ( int  x,
int  y
