## Detailed Description

position a point in 3D space

This 3D widget allows the user to position a point in 3D space using a 3D cursor. The cursor has an outline bounding box, axes-aligned cross-hairs, and axes shadows. (The outline and shadows can be turned off.) Any of these can be turned off. A nice feature of the object is that the vtkPointWidget, like any 3D widget, will work with the current interactor style. That is, if vtkPointWidget does not handle an event, then all other registered observers (including the interactor style) have an opportunity to process the event. Otherwise, the vtkPointWidget will terminate the processing of the event that it handles.

To use this object, just invoke SetInteractor() with the argument of the method a vtkRenderWindowInteractor. You may also wish to invoke "PlaceWidget()" to initially position the widget. The interactor will act normally until the "i" key (for "interactor") is pressed, at which point the vtkPointWidget will appear. (See superclass documentation for information about changing this behavior.) To move the point, the user can grab (left mouse) on any widget line and "slide" the point into position. Scaling is achieved by using the right mouse button "up" the render window (makes the widget bigger) or "down" the render window (makes the widget smaller). To translate the widget use the middle mouse button. (Note: all of the translation interactions can be constrained to one of the x-y-z axes by using the "shift" key.) The vtkPointWidget produces as output a polydata with a single point and a vertex cell.

Some additional features of this class include the ability to control the rendered properties of the widget. You can set the properties of the selected and unselected representations of the parts of the widget. For example, you can set the property of the 3D cursor in its normal and selected states.

The constrained translation/sliding action (i.e., when the "shift" key is depressed) along the axes is based on a combination of a "hot" spot around the cursor focus plus the initial mouse motion after selection. That is, if the user selects an axis outside of the hot spot, then the motion is constrained along that axis. If the user selects the point widget near the focus (within the hot spot), the initial motion defines a vector which is compared to the x-y-z axes. The motion is constrained to the axis that is most parallel to the initial motion vector.

Methods invoked by print to print information about the object including superclasses.

Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

## ◆ SetEnabled()

## ◆ PlaceWidget() [1/3]

void vtkPointWidget::PlaceWidget | ( | double | bounds[6] | ) |
| override virtual

This method is used to initially place the widget.

The placement of the widget depends on whether a Prop3D or input dataset is provided. If one of these two is provided, they will be used to obtain a bounding box, around which the widget is placed. Otherwise, you can manually specify a bounds with the PlaceWidget(bounds) method. Note: PlaceWidget(bounds) is required by all subclasses; the other methods are provided as convenience methods.
