15 Window-Point Pick Data Structure

You use a window-point pick data structure to specify information when creating a pick object for subsequent window-point picking. A window-point pick data structure is defined by the TQ3WindowPointPickData data type.

typedef struct TQ3WindowPointPickData {
 TQ3PickData         data;
 TQ3Point2D         point;
 float         vertexTolerance;
 float         edgeTolerance;
} TQ3WindowPointPickData;
data A pick data structure specifying basic information about the window-point pick object.
point A point, in window coordinates.
vertexTolerance The vertex tolerance.
edgeTolerance The edge tolerance.
