Detailed Description

VSG extension Special separator that performs locate highlighting.

This is a subclass of SoSeparator that redraws itself in a different color when the cursor is over the contents of the separator.

The redraw happens for that separator only and not the entire window (redraw along the handle event pick path) and in the front buffer, to efficiently track the mouse motion. The highlighted redraw overrides the emissive and/or diffuse color of the subgraph based on the field values in this node.

NOTE: when using SoLightModel::BASE_COLOR (to turn lighting off) only the diffuse color will be used to render objects, so EMISSIVE_DIFFUSE must be used for this node to have any effect.

Limitations:

  • When using a SceneExaminer, subgraph can remain highlighted after switching from selection mode to viewing mode.
  • When using an examiner viewer or a SceneExaminer, subgraph can remain unhighlighted when switching from viewing mode to selection mode until the mouse is moved.
  • The SceneOrbiter does not have such limitation.

    To override the default mode (off), set environment variable IV_ALLOW_LOCATE_HIGHLIGHT to 1. This will allow locate highlighting to happen by default.

FILE FORMAT/DEFAULT

    LocateHighlight {
    boundingBoxCaching AUTO
    renderCulling AUTO
    pickCulling AUTO
    mode OFF
    style EMISSIVE
    color 0.3 0.3 0.3
    fastEditing DISABLE
    }

ACTION BEHAVIOR

    SoHandleEventAction
    Checks to see if the cursor moves onto or off of the contents of the separator, and redraws appropriately (if mode is AUTO), otherwise traverses as a normal separator.

    SoGLRenderAction
    Redraws either highlighted (if cursor is over the contents of the separator when mode == AUTO or always if mode == ON), otherwise traverses as a normal separator.

Member Enumeration Documentation

◆ Modes

Possible values for the mode.

Enumerator
AUTO 

Highlight when mouse is over.

ON 

Always highlight.

OFF 

Never highlight (default)

Definition at line 151 of file SoLocateHighlight.h.

◆ Styles

Possible values for draw style.

Enumerator
EMISSIVE 

Changes emissive color only (default)

EMISSIVE_DIFFUSE 

Changes emissive and diffuse colors.

Constructor & Destructor Documentation

◆ SoLocateHighlight()

SoLocateHighlight::SoLocateHighlight ( )

Creates a LocateHighlight node with default settings.

Member Function Documentation

◆ getClassTypeId()

static SoType SoLocateHighlight::getClassTypeId ( )
static

Returns the type identifier for this class.


◆ getTypeId()

virtual SoType SoLocateHighlight::getTypeId ( ) const
virtual

Returns the type identifier for this specific instance.

Reimplemented from SoSeparator.

Reimplemented in SoWWWAnchor.

◆ turnOffCurrentHighlight()

static SoDEPRECATED void SoLocateHighlight::turnOffCurrentHighlight ( SoGLRenderAction action)
static

This will de-highlight the currently highlighted node if any.

this should be called when the cursor leaves a window or a mode changes happen which would prevent a highlighted node from receiving more mouse motion events. The GL render action used to render into that window needs to be passed to correctly un-highlight.
