The bi-dimensional measure is defined by two finite, orthogonal lines that intersect within the finite extent of both lines. The lengths of these two lines gives the bi-dimensional measure. Each line is defined by two handle widgets at the end points of each line. The orthogonal constraint on the two lines limits how the four end points can be positioned. The first two points can be placed arbitrarily to define the first line (similar to vtkDistanceWidget). The placement of the third point is limited by the finite extent of the first line. As the third point is placed, the fourth point is placed on the opposite side of the first line. Once the third point is placed, the second line is defined since the fourth point is defined at the same time, but the fourth point can be moved along the second line (i.e., maintaining the orthogonal relationship between the two lines). Once defined, any of the four points can be moved along their constraint lines. Also, each line can be translated along the other line (in an orthogonal direction), and the whole bi-dimensional widget can be rotated about its center point (see the description of the event bindings). Finally, selecting the point where the two orthogonal axes intersect, the entire widget can be translated in any direction. Placement of any point results in a special PlacePointEvent invocation so that special operations may be performed to reposition the point. Motion of any point, moving the lines, or rotating the widget cause InteractionEvents to be invoked. Note that the widget has two fundamental modes: a define mode (when initially placing the points) and a manipulate mode (after the points are placed). Line translation and rotation are only possible in manipulate mode. To use this widget, specify an instance of vtkBiDimensionalWidget and a representation (e.g., vtkBiDimensionalRepresentation2D). The widget is implemented using four instances of vtkHandleWidget which are used to position the end points of the two intersecting lines. The representations for these handle widgets are provided by the vtkBiDimensionalRepresentation class. @par Event Bindings: By default, the widget responds to the following VTK events (i.e., it watches the vtkRenderWindowInteractor for these events): LeftButtonPressEvent - define a point or manipulate a handle, line, perform rotation or translate the widget. MouseMoveEvent - position the points, move a line, rotate or translate the widget LeftButtonReleaseEvent - release the selected handle and end interaction @par Event Bindings: Note that the event bindings described above can be changed using this class's vtkWidgetEventTranslator. This class translates VTK events into the vtkBiDimensionalWidget's widget events: vtkWidgetEvent::AddPoint -- (In Define mode:) Add one point; depending on the state it may the first, second, third or fourth point added. (In Manipulate mode:) If near a handle, select the handle. Or if near a line, select the line. vtkWidgetEvent::Move -- (In Define mode:) Position the second, third or fourth point. (In Manipulate mode:) Move the handle, line or widget. vtkWidgetEvent::EndSelect -- the manipulation process has completed. @par Event Bindings: This widget invokes the following VTK events on itself (which observers can listen for): vtkCommand::StartInteractionEvent (beginning to interact) vtkCommand::EndInteractionEvent (completing interaction) vtkCommand::InteractionEvent (moving a handle, line or performing rotation) vtkCommand::PlacePointEvent (after a point is positioned; call data includes handle id (0,1,2,4)) @sa vtkHandleWidget vtkDistanceWidget """ def CreateDefaultRepresentation(self): # real signature unknown; restored from __doc__ """ CreateDefaultRepresentation(self) -> None C++: void CreateDefaultRepresentation() override; Create the default widget representation if one is not set.
