SoExtSelectionSelectionEventCallback Delegate

This is the declaration to use for selection event callback functions.

Namespace: OIV.Inventor.Nodes
Assembly: OIV.Inventor (in OIV.Inventor.dll) Version: 2023.1.3.0 (2023.1.3)

Syntax

public delegate bool SelectionEventCallback(
	SbVec2s position,
	SbVec3f scenePosition,
	SoExtSelection selection
)

Public Delegate Function SelectionEventCallback ( 
	position As SbVec2s,
	scenePosition As SbVec3f,
	selection As SoExtSelection
) As Boolean

public delegate bool SelectionEventCallback(
	SbVec2s position, 
	SbVec3f scenePosition, 
	SoExtSelection^ selection
)

type SelectionEventCallback = 
    delegate of 
        position : SbVec2s * 
        scenePosition : SbVec3f * 
        selection : SoExtSelection -> bool

Parameters

position: Type: OIV.InventorSbVec2s
The position of the event in pixel coordinates (0,0 is lower left corner).
scenePosition: Type: OIV.InventorSbVec3f
The position of the event in normalized -1..1 3D coordinates.
selection: Type: OIV.Inventor.NodesSoExtSelection
The selection node that called the function.

Return Value

Type: Boolean

If the callback handles the event it must return true, else return false.

Remarks

See OIV.Inventor.Nodes.SoExtSelection.StartSelectionCallback, OIV.Inventor.Nodes.SoExtSelection.EndSelectionCallback, and OIV.Inventor.Nodes.SoExtSelection.MovingSelectionCallback. These callbacks are useful to modify the selection scene graph (see setSelectionSceneGraph) to implement dynamically changing selection feedback.

Note: These callbacks can only be used in FastEdit mode.
