Member Function Documentation

static int vtkContextTransform::IsTypeOf ( const char * name ) [static]

Return 1 if this class type 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 vtkAbstractContextItem.

virtual int vtkContextTransform::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 vtkAbstractContextItem.

static vtkContextTransform* vtkContextTransform::SafeDownCast ( vtkObjectBase * o ) [static]

Reimplemented from vtkAbstractContextItem.

Reimplemented from vtkAbstractContextItem.

static vtkContextTransform* vtkContextTransform::New ( ) [static]

Creates a vtkContextTransform object.

Reimplemented from vtkObject.

Reimplemented from vtkAbstractContextItem.

virtual bool vtkContextTransform::Paint ( vtkContext2D * painter ) [virtual]

Paint event for the item, called whenever the item needs to be drawn.

Reimplemented from vtkAbstractContextItem.

virtual void vtkContextTransform::Translate	(	float	dx,

	)		`[virtual]`

Translate the item by the specified amounts dx and dy in the x and y directions.

virtual void vtkContextTransform::Scale	(	float	dx,
		float	dy
	)		`[virtual]`

Scale the item by the specified amounts dx and dy in the x and y directions.

virtual void vtkContextTransform::Rotate ( float angle ) [virtual]

Rotate the item by the specified angle.

virtual vtkTransform2D* vtkContextTransform::GetTransform ( ) [virtual]

Access the vtkTransform2D that controls object transformation.

virtual vtkVector2f vtkContextTransform::MapToParent ( const vtkVector2f & point ) [virtual]

Transforms a point to the parent coordinate system.

Reimplemented from vtkAbstractContextItem.
