Enumerates types of visual objects that the flow chart control can display.
TdxFcHitTest = set of (htNowhere, htByObject, htOnObject, htOnConnection, htOnConLabel, htOnArrowSrc, htOnArrowDst, htOnSelPoint, htOnRotateMark, htOnParameter);
| Type |

| dxflchrt.TEnum~htNowhere.htOnParameter |
The corresponding flag is present if the point whose coordinates are passed as the X and Y parameters, is:
| Value | Description |
|---|---|
| htNowhere | Located in an empty portion of the control’s area. |
| htByObject | Within a chart symbol‘s bounding rectangle. |
| htOnObject | Within a chart symbol’s shape. Since the chart symbol’s shape is always within the bounding rectangle, the htByObject flag is also present in the GetHitTestAt function’s result. |
| htOnConnection | At a connection‘s area. |
| htOnConLabel | At a connection’s label. |
| htOnArrowSrc | Within the area occupied by a connection’s source arrow. Since the connection’s source arrow is created by its connection, the htOnConnection flag is also present in the GetHitTestAt function’s result. |
| htOnArrowDst | Within the area occupied by a connection’s destination arrow. Since the connection’s destination arrow is created by its connection, the htOnConnection flag is also present in the GetHitTestAt function’s result. |
| htOnSelPoint | Within the area occupied by an anchor point of any selected chart symbol or connection. |
| htOnRotateMark | Within the rotation mark’s bounding rectangle. |
The chart symbol’s HitTest function references the TdxFcHitTestType.
