A wireframe highlight style.
SoLineHighlightRenderAction is a render action which renders the specified scene graph, then renders each selected object again in wireframe. If there is no renderable geometry in a selected object, no highlight is rendered for that object.
Selected objects are specified by the first selection node (SoSelection or SoExtSelection) node in the scene to which this action is applied. If there is no selection node in the scene graph, then no objects will be highlighted.
The application must explicitly tell Open Inventor to use a highlight render action in place of the default SoGLRenderAction in the SoSceneManager class using the setGLRenderAction() method. The viewer classes provide a convenience setGLRenderAction() method that calls SoSceneManager (see e.g. SoWinRenderArea).
For convenience, the viewer classes also provide the redrawOnSelectionChange() method. This method attaches a sensor to the specified selection node and automatically schedules a redraw if the set of selected objects is modified.
Other highlight effects are available including "halo" highlighting.

Default is solid, 0xffff. The pattern of bits in the passed variable specifies the pattern of the line. See SoDrawStyle for more information. The application is responsible for forcing a redraw of the scene to see the effects of this change.
| void SoLineHighlightRenderAction::setLineWidth | ( | float | width | ) |
Sets the line width of the highlight.
Default is 3. The application is responsible for forcing a redraw of the scene to see the effects of this change.
