TcxRectBasedGeometryObject.IsEmpty Method

Identifies if geometry information corresponds to an empty rectangle or zero margins.

Declaration

function IsEmpty: Boolean; virtual;

Returns

Type	Description
Boolean	True if the underlying rectangle’s area is 0 or a negative number; otherwise, False.

Remarks

Draw routines can call this function to identify if they should take the stored geometry-based information into account. For instance, a draw routine can use a simpler algorithm if the IsEmpty function returns True.
