public class SoLineHighlightRenderAction
extends SoGLRenderAction

Selection highlight style. SoLineHighlightRenderAction is a render action which renders the specified scene graph, then renders each selected object again in wireframe. Selected objects are specified by the first SoSelection node in the scene to which this action is applied. If there is no renderable geometry in a selected object, no highlight is rendered for that object. A highlight render action can be passed to the setGLRenderAction() method of SoWinRenderArea to have an effect on scene graphs.

EXAMPLE

Here is an example of how a line highlight can be specified for a particular selection node and render area.

SoWinRenderArea *myRenderArea;

SoSelection *mySelection;

// Set the highlight render action

myRenderArea->setGLRenderAction(

new SoLineHighlightRenderAction());

// Automatic redraw on selection changes

myRenderArea->redrawOnSelectionChange(mySelection);

Constructor Detail

SoLineHighlightRenderAction

public SoLineHighlightRenderAction(SbViewportRegion viewportRegion)

Constructor which takes the normal SoGLRenderAction parameters.

SoLineHighlightRenderAction

public SoLineHighlightRenderAction()

Constructor.

Method Detail

getLinePattern

public short getLinePattern()

Gets the line pattern of the highlight.

setColor

public void setColor(SbColor c)

Sets the color of the highlight. Default is red (1,0,0). The application is responsible for forcing a redraw of the scene to see the effects of this change.

getColor

public SbColor getColor()

Gets the color of the highlight.

setLinePattern

public void setLinePattern(short pattern)

Sets the line pattern of the highlight. 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.

setLineWidth

public void 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.

setVisible

public void setVisible(boolean b)

This provides a convenient mechanism for turning highlights off or back on. When false is passed, subsequent calls to apply() render the scene graph without rendering highlights. The application is responsible for forcing a redraw of the scene after changing this state. The default visibility is on.

setPointSize

public void setPointSize(float size)

Sets the size of points (diameter in pixels) rendered by the highlight. Default is 1. Value must be greater than zero. Only applies to point primitives, e.g. SoPointSet.

getPointSize

public float getPointSize()

Gets the point size of the highlight.

isVisible

public boolean isVisible()

Returns whether highlights will be rendered or not.

getLineWidth

public float getLineWidth()

Gets the line width of the highlight.

enableElement

public static void enableElement(java.lang.Class<? extends Inventor> t,
                                 int stkIndex)
