|
| void | SetRepresentation (vtkContourRepresentation r) |

| virtual int | GetManagesCursor () |
| | Turn on or off the management of the cursor. Cursor management is typically disabled for subclasses when composite widgets are created. For example, vtkHandleWidgets are often used to create composite widgets, and the parent widget takes over the cursor management.
|
| virtual vtkAbstractWidget | GetParent () |
| | Specifying a parent to this widget is used when creating composite widgets. It is an internal method not meant to be used by the public. When a widget has a parent, it defers the rendering to the parent. It may also defer managing the cursor (see ManagesCursor ivar).

| | Return an instance of vtkWidgetRepresentation used to represent this widget in the scene. Note that the representation is a subclass of vtkProp (typically a subclass of vtkWidgetRepresenation) so it can be added to the renderer independent of the widget.
|
| virtual void | ManagesCursorOff () |

| | Methods to change the whether the widget responds to interaction. Set this to Off to disable interaction. On by default. Subclasses must overide SetProcessEvents() to make sure that they pass on the flag to all component widgets.
|
| void | Render () |
| | This method is called by subclasses when a render method is to be invoked on the vtkRenderWindowInteractor. This method should be called (instead of vtkRenderWindow::Render() because it has built into it optimizations for minimizing renders and/or speeding renders.
|
| virtual void | SetManagesCursor (int _arg) |
| | Turn on or off the management of the cursor. Cursor management is typically disabled for subclasses when composite widgets are created. For example, vtkHandleWidgets are often used to create composite widgets, and the parent widget takes over the cursor management.

| | Specifying a parent to this widget is used when creating composite widgets. It is an internal method not meant to be used by the public. When a widget has a parent, it defers the rendering to the parent. It may also defer managing the cursor (see ManagesCursor ivar).
|
| override void | SetPriority (float arg0) |
| | Override the superclass method. This will automatically change the priority of the widget. Unlike the superclass documentation, no methods such as SetInteractor to null and reset it etc. are necessary.
|
| virtual void | SetProcessEvents (int _arg) |
| | Methods to change the whether the widget responds to interaction. Set this to Off to disable interaction. On by default. Subclasses must overide SetProcessEvents() to make sure that they pass on the flag to all component widgets.

| | vtkInteractorObserver (IntPtr rawCppThis, bool callDisposalMethod, bool strong) |
| | Automatically generated constructor - called from generated code. DO NOT call directly.
|
| void | EnabledOff () |
| | Methods for turning the interactor observer on and off, and determining its state. All subclasses must provide the SetEnabled() method.

| | Methods for turning the interactor observer on and off, and determining its state. All subclasses must provide the SetEnabled() method. Enabling a vtkInteractorObserver has the side effect of adding observers; disabling it removes the observers. Prior to enabling the vtkInteractorObserver you must set the render window interactor (via SetInteractor()). Initial value is 0.
|
| virtual vtkRenderer | GetCurrentRenderer () |
| | Set/Get the current renderer. Normally when the widget is activated (SetEnabled(1) or when keypress activation takes place), the renderer over which the mouse pointer is positioned is used and assigned to this Ivar. Alternatively, you might want to set the CurrentRenderer explicitly. WARNING: note that if the DefaultRenderer Ivar is set (see above), it will always override the parameter passed to SetCurrentRenderer, unless it is NULL. (i.e., SetCurrentRenderer(foo) = SetCurrentRenderer(DefaultRenderer).

| virtual vtkRenderer | GetDefaultRenderer () |
| | Set/Get the default renderer to use when activating the interactor observer.

|
| int | GetEnabled () |

|
| virtual int | GetKeyPressActivation () |
| | Enable/Disable of the use of a keypress to turn on and off the interactor observer. (By default, the keypress is 'i' for "interactor observer".) Set the KeyPressActivationValue to change which key activates the widget.)

| | Specify which key press value to use to activate the interactor observer (if key press activation is enabled). By default, the key press activation value is 'i'.

|
| virtual float | GetPriority () |
| | Set/Get the priority at which events are processed. This is used when multiple interactor observers are used simultaneously. The default value is 0.0 (lowest priority.) Note that when multiple interactor observer have the same priority, then the last observer added will process the event first.

You will have to SetInteractor(NULL), change priority, and then SetInteractor(iren) to have the priority take effect.)
|

You will have to SetInteractor(NULL), change priority, and then SetInteractor(iren) to have the priority take effect.)
|
| virtual float | GetPriorityMinValue () |

Note that when multiple interactor observer have the same priority, then the last observer added will process the event first. (Note: once the SetInteractor() method has been called, changing the priority does not effect event processing. You will have to SetInteractor(NULL), change priority, and then SetInteractor(iren) to have the priority take effect.)

vtkContourWidget - create a contour with a set of points
Description The vtkContourWidget is used to select a set of points, and draw lines between these points. The contour may be opened or closed, depending on how the last point is added. The widget handles all processing of widget events (that are triggered by VTK events). The vtkContourRepresentation is responsible for all placement of the points, calculation of the lines, and contour manipulation. This is done through two main helper classes: vtkPointPlacer and vtkContourLineInterpolator. The representation is also responsible for drawing the points and lines.
Event Bindings By default, the widget responds to the following VTK events (i.e., it watches the vtkRenderWindowInteractor for these events): <pre> LeftButtonPressEvent - triggers a Select event RightButtonPressEvent - triggers a AddFinalPoint event MouseMoveEvent - triggers a Move event LeftButtonReleaseEvent - triggers an EndSelect event Delete key event - triggers a Delete event Shift + Delete key event - triggers a Reset event </pre>
Note that the event bindings described above can be changed using this class's vtkWidgetEventTranslator. This class translates VTK events into the vtkContourWidget's widget events: <pre> vtkWidgetEvent::Select widget state is: Start or Define: If we already have at least 2 nodes, test whether the current (X,Y) location is near an existing node. If so, close the contour and change to Manipulate state. Otherwise, attempt to add a node at this (X,Y) location. Manipulate: If this (X,Y) location activates a node, then set the current operation to Translate. Otherwise, if this location is near the contour, attempt to add a new node on the contour at this (X,Y) location.
vtkWidgetEvent::AddFinalPoint widget state is: Start: Do nothing. Define: If we already have at least 2 nodes, test whether the current (X,Y) location is near an existing node. If so, close the contour and change to Manipulate state. Otherwise, attempt to add a node at this (X,Y) location. If we do, then leave the contour open and change to Manipulate state. Manipulate: Do nothing.
vtkWidgetEvent::Move widget state is: Start or Define: Do nothing. Manipulate: If our operation is Translate, then invoke WidgetInteraction() on the representation. If our operation is Inactive, then just attempt to activate a node at this (X,Y) location.
vtkWidgetEvent::EndSelect widget state is: Start or Define: Do nothing. Manipulate: If our operation is not Inactive, set it to Inactive.
vtkWidgetEvent::Delete widget state is: Start: Do nothing. Define: Remove the last point on the contour. Manipulate: Attempt to activate a node at (X,Y). If we do activate a node, delete it. If we now have less than 3 nodes, go back to Define state.
vtkWidgetEvent::Reset widget state is: Start: Do nothing. Define: Remove all points and line segments of the contour. Essentially calls Intialize(NULL) Manipulate: Do nothing. </pre>
This widget invokes the following VTK events on itself (which observers can listen for): <pre> vtkCommand::StartInteractionEvent (beginning to interact) vtkCommand::EndInteractionEvent (completing interaction) vtkCommand::InteractionEvent (moving after selecting something) vtkCommand::PlacePointEvent (after point is positioned; call data includes handle id (0,1)) vtkCommand::WidgetValueChangedEvent (Invoked when the contour is closed for the first time. ) </pre>
