PtInRect

Check whether a point is inside a rectangle.

Declaration

Source position: types.pp line 317

function PtInRect(

  const Rect: TRect;

  const p: TPoint

):Boolean;

Description

PtInRect returns True if p is located inside Rect, and False if it is located outside the rectangle.

Remark: 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.
