.Top specifies the Y coordinate of the upper-left corner of a control, relative to its parent or containing control in pixels.
Use Top to locate the top of the control or reposition the control to a different Y coordinate. The Top property, like the Left property, is the position of the control relative to its container. Thus, if a control is contained in a TPanel, the Left and Top properties are relative to the panel. If the control is contained directly by the form, it is relative to the form. For forms, the value of the Top property is relative to the screen in pixels.
Here is the example of drawing a rectangle with Top=5:
