Usage
The vtkAngleRepresentation is a superclass for classes
representing the vtkAngleWidget. This representation
consists of two rays and three vtkHandleRepresentations to
place and manipulate the three points defining the angle
representation. (Note: the three points are referred to as
Point1, Center, and Point2, at the two end points (Point1
and Point2) and Center (around which the angle is measured).
To create an instance of class vtkAngleRepresentation,
simply invoke its constructor as follows
obj = vtkAngleRepresentation
Methods
The class vtkAngleRepresentation has several methods that
can be used. They are listed below. Note that the
documentation is translated automatically from the VTK
sources, and may not be completely intelligible. When in
doubt, consult the VTK website. In the methods listed below,
obj is an instance of the vtkAngleRepresentation class.
* string = obj.GetClassName () - Standard VTK methods.
* int = obj.IsA (string name) - Standard VTK methods.
* vtkAngleRepresentation = obj.NewInstance () - Standard VTK
methods.
* vtkAngleRepresentation = obj.SafeDownCast (vtkObject o) -
Standard VTK methods.
* double = obj.GetAngle () - This representation and all
subclasses must keep an angle (in degrees) consistent with
the state of the widget.
* obj.GetPoint1WorldPosition (double pos[3]) - Methods to
Set/Get the coordinates of the three points defining this
representation. Note that methods are available for both
display and world coordinates.
* obj.GetCenterWorldPosition (double pos[3]) - Methods to
Set/Get the coordinates of the three points defining this
representation. Note that methods are available for both
display and world coordinates.
* obj.GetPoint2WorldPosition (double pos[3]) - Methods to
Set/Get the coordinates of the three points defining this
representation. Note that methods are available for both
display and world coordinates.
* obj.SetPoint1DisplayPosition (double pos[3]) - Methods to
Set/Get the coordinates of the three points defining this
representation. Note that methods are available for both
display and world coordinates.
* obj.SetCenterDisplayPosition (double pos[3]) - Methods to
Set/Get the coordinates of the three points defining this
representation. Note that methods are available for both
display and world coordinates.
* obj.SetPoint2DisplayPosition (double pos[3]) - Methods to
Set/Get the coordinates of the three points defining this
representation. Note that methods are available for both
display and world coordinates.
* obj.GetPoint1DisplayPosition (double pos[3]) - Methods to
Set/Get the coordinates of the three points defining this
representation. Note that methods are available for both
display and world coordinates.
* obj.GetCenterDisplayPosition (double pos[3]) - Methods to
Set/Get the coordinates of the three points defining this
representation. Note that methods are available for both
display and world coordinates.
* obj.GetPoint2DisplayPosition (double pos[3]) - Methods to
Set/Get the coordinates of the three points defining this
representation. Note that methods are available for both
display and world coordinates.
* obj.SetHandleRepresentation (vtkHandleRepresentation
handle) - This method is used to specify the type of
handle representation to use for the three internal
vtkHandleWidgets within vtkAngleRepresentation. To use
this method, create a dummy vtkHandleRepresentation (or
subclass), and then invoke this method with this dummy.
Then the vtkAngleRepresentation uses this dummy to clone
three vtkHandleRepresentations of the same type. Make sure
you set the handle representation before the widget is
enabled. (The method InstantiateHandleRepresentation() is
invoked by the vtkAngle widget.)
* obj.InstantiateHandleRepresentation () - This method is
used to specify the type of handle representation to use
for the three internal vtkHandleWidgets within
vtkAngleRepresentation. To use this method, create a dummy
vtkHandleRepresentation (or subclass), and then invoke
this method with this dummy. Then the
vtkAngleRepresentation uses this dummy to clone three
vtkHandleRepresentations of the same type. Make sure you
set the handle representation before the widget is
enabled. (The method InstantiateHandleRepresentation() is
invoked by the vtkAngle widget.)
* vtkHandleRepresentation = obj.GetPoint1Representation () -
Set/Get the handle representations used for the
vtkAngleRepresentation.
* vtkHandleRepresentation = obj.GetCenterRepresentation () -
Set/Get the handle representations used for the
vtkAngleRepresentation.
* vtkHandleRepresentation = obj.GetPoint2Representation () -
Set/Get the handle representations used for the
vtkAngleRepresentation.
* obj.SetTolerance (int ) - The tolerance representing the
distance to the representation (in pixels) in which the
cursor is considered near enough to the end points of the
representation to be active.
* int = obj.GetToleranceMinValue () - The tolerance
representing the distance to the representation (in
pixels) in which the cursor is considered near enough to
the end points of the representation to be active.
* int = obj.GetToleranceMaxValue () - The tolerance
representing the distance to the representation (in
pixels) in which the cursor is considered near enough to
the end points of the representation to be active.
* int = obj.GetTolerance () - The tolerance representing the
distance to the representation (in pixels) in which the
cursor is considered near enough to the end points of the
representation to be active.
* obj.SetLabelFormat (string ) - Specify the format to use
for labelling the angle. Note that an empty string results
in no label, or a format string without a "%" character
will not print the angle value.
* string = obj.GetLabelFormat () - Specify the format to use
for labelling the angle. Note that an empty string results
in no label, or a format string without a "%" character
will not print the angle value.
* obj.SetRay1Visibility (int ) - Special methods for turning
off the rays and arc that define the cone and arc of the
angle.
* int = obj.GetRay1Visibility () - Special methods for
turning off the rays and arc that define the cone and arc
of the angle.
* obj.Ray1VisibilityOn () - Special methods for turning off
the rays and arc that define the cone and arc of the
angle.
* obj.Ray1VisibilityOff () - Special methods for turning off
the rays and arc that define the cone and arc of the
angle.
* obj.SetRay2Visibility (int ) - Special methods for turning
off the rays and arc that define the cone and arc of the
angle.
* int = obj.GetRay2Visibility () - Special methods for
turning off the rays and arc that define the cone and arc
of the angle.
* obj.Ray2VisibilityOn () - Special methods for turning off
the rays and arc that define the cone and arc of the
angle.
* obj.Ray2VisibilityOff () - Special methods for turning off
the rays and arc that define the cone and arc of the
angle.
* obj.SetArcVisibility (int ) - Special methods for turning
off the rays and arc that define the cone and arc of the
angle.
* int = obj.GetArcVisibility () - Special methods for
turning off the rays and arc that define the cone and arc
of the angle.
* obj.ArcVisibilityOn () - Special methods for turning off
the rays and arc that define the cone and arc of the
angle.
* obj.ArcVisibilityOff () - Special methods for turning off
the rays and arc that define the cone and arc of the
angle.
* obj.BuildRepresentation () - These are methods that
satisfy vtkWidgetRepresentation's API.
* int = obj.ComputeInteractionState (int X, int Y, int
modify) - These are methods that satisfy
vtkWidgetRepresentation's API.
* obj.StartWidgetInteraction (double e[2]) - These are
methods that satisfy vtkWidgetRepresentation's API.
