PtInRect function
Check whether a point is inside a rectangle.
Declaration
function PtInRect(const Rect: TRect; const p: TPoint): BooleanDescription
PtInRect returns
True if
p is located
inside
Rect, and
False if it is located outside the
rectangle.
Note that the bottom, right edges are not considered
part of the rectangle, therefor a point located on one of these edges will
not be considered part of the rectangle, meaning that for a record
(10,10,100,100) the point (90,100) will not be considered part of the
record, but
90,10 will be.
