TdxFcHitTest Type

Enumerates types of visual objects that the flow chart control can display.

Declaration

TdxFcHitTest = set of (htNowhere, htByObject, htOnObject, htOnConnection, htOnConLabel, htOnArrowSrc, htOnArrowDst, htOnSelPoint, htOnRotateMark, htOnParameter);

Referenced Class

Type
dxflchrt.TEnum~htNowhere.htOnParameter

Remarks

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.
