| HitInfo | HitInfo is the basic info object. Derived from that are the clsses HitItemList.drawLineInfo, HitItemList.drawPolyInfo, HitItemList.drawPolyPolyInfo, HitItemList.drawCurveInfo, HitItemList.drawPolyCurveInfo, HitItemList.drawPolyPolyCurveInfo, HitItemList.drawSurfaceInfo, HitItemList.drawPointInfo, HitItemList.drawTextInfo, HitItemList.drawImageInfo If you wish more informationa about a catched drawing, the you obtain this in the field Info In this field is a infoobject stored. It's depends on KindOfPrimitiv. So you can for example cast the field HitItem.Info to drawLineInfo, if KindOfPrimitiv equals HitItemList.Primitives.Line is. |
| HitItem | |
| HitItemList | The HitItemList is the container for HitItem. She is needed to point to a graphical object with a mousepointer for example. It may be, that many objects are laying on the place, where the mousepointer is. Evrey drawing, who is nearly to the point produces a Hititem-entry in the HitItemList. The HitItemList will be refreshed when you call the Select-method with a Point as parameter. He indicates, where the mousepointer is located. To every Hititem belongs a primitive drawmethod, who is "near" to that point. This means, the distance of the drawing to the point is smaller than CatchDistance. A Hititem holds a lot of information about the primitive drawing, see Info and HitItem The entries in the HitItmList are sorted by the following priorities: 1. Distance to the Eye, also called z-Order 2. Keep-old-current : the "oldcurrent" has priority. This avoid a flickering of the catchresults. 3. Point before Lines before Planes. |

| HitItemList.drawLineInfo | drawLineInfo is an instance of HitInfo. You can get it from Hititem.Info if the Hititem.KindOfPrimitiv equals HitItemList.Primitives.Line In this case you can cast Hititem.Info by (drawLineInfo)Hititem.Info; |
| HitItemList.drawPointInfo | drawPointInfo is an instance of HitInfo. You can get it from Hititem.Info if the Hititem.KindOfPrimitiv equals HitItemList.Primitives.Point In this case you can cast Hititem.Info by (drawPointInfo)Hititem.Info; |
| HitItemList.drawPolyCurveInfo | drawPolyCurveInfo is an instance of HitInfo. You can get it from Hititem.Info if the Hititem.KindOfPrimitiv equals HitItemList.Primitives.PolyCurve In this case you can cast Hititem.Info by (drawPolyCurveInfo)Hititem.Info; |
| HitItemList.drawPolyInfo | drawPolyInfo is an instance of HitInfo. You can get it from Hititem.Info if the Hititem.KindOfPrimitiv equals HitItemList.Primitives. PolyLine In this case you can cast Hititem.Info by (drawPolyInfo)Hititem.Info; |
| HitItemList.drawPolyPolyCurveInfo | drawPolyPolyCurveInfo is an instance of HitInfo. You can get it from Hititem.Info if the Hititem.KindOfPrimitiv equals HitItemList.Primitives.PolyPolyCurve In this case you can cast Hititem.Info by (drawPolyPolyCurveInfo)Hititem.Info; |
| HitItemList.drawPolyPolyInfo | drawPolyPolyInfo is an instance of HitInfo. You can get it from Hititem.Info if the Hititem.KindOfPrimitiv equals HitItemList.Primitives. PolyPolyLine In this case you can cast Hititem.Info by (drawPolyPolyInfo)Hititem.Info; |
| HitItemList.drawSurfaceInfo | drawSurfaceInfo is an instance of HitInfo. You can get it from Hititem.Info if the Hititem.KindOfPrimitiv equals HitItemList.Primitives.Surface In this case you can cast Hititem.Info by (drawSurfaceInfo)Hititem.Info; |
| HitItemList.drawTextInfo | drawTextInfo is an instance of HitInfo. You can get it from Hititem.Info if the Hititem.KindOfPrimitiv equals HitItemList.Primitives.Text In this case you can cast Hititem.Info by (drawTextInfo)Hititem.Info; |
