Visual FoxPro 9.0 SP2
Box Method
Draws a rectangle on a Form object. There are two versions of the syntax.
Object.Box(nXCoord1, nYCoord1, nXCoord2, nYCoord2)
Object.Box(nXCoord2, nYCoord2)
Parameters
nXCoord1, nYCoord1
Specifies the coordinates of the starting point for the rectangle. The ScaleMode method of the form determines the unit of measurement used. If you omit these arguments, the value of CurrentX and CurrentY are used.
nXCoord2, nYCoord2
Specifies the endpoint of the rectangle.
Remarks
Applies To: Form Object | _SCREEN System Variable
The width of the lines drawn depends on the DrawWidth property setting. How a rectangle is drawn on the background depends on the settings of the DrawMode and DrawStyle properties. When the Box method is called, the CurrentX and CurrentY properties are set to the endpoint specified by the last two arguments.
