measure the distance between two points
<p>
The <a class="el" href="a00430.html" title="measure the distance between two points">vtkDistanceWidget</a> is used to measure the distance between two points. The two end points can be positioned independently, and when they are released, a special PlacePointEvent is invoked so that special operations may be take to reposition the point (snap to grid, etc.) The widget has two different modes of interaction: when initially defined (i.e., placing the two points) and then a manipulate mode (adjusting the position of the two points).<p>
To use this widget, specify an instance of <a class="el" href="a00430.html" title="measure the distance between two points">vtkDistanceWidget</a> and a representation (a subclass of <a class="el" href="a00428.html" title="represent the vtkDistanceWidget">vtkDistanceRepresentation</a>). The widget is implemented using two instances of <a class="el" href="a00679.html" title="a general widget for moving handles">vtkHandleWidget</a> which are used to position the end points of the line. The representations for these two handle widgets are provided by the <a class="el" href="a00428.html" title="represent the vtkDistanceWidget">vtkDistanceRepresentation</a>.<p>
<dl class="user" compact><dt><b>Event Bindings:</b></dt><dd>By default, the widget responds to the following VTK events (i.e., it watches the <a class="el" href="a01491.html" title="platform-independent render window interaction including picking and frame rate control...">vtkRenderWindowInteractor</a> for these events): <pre>
LeftButtonPressEvent - add a point or select a handle
