WFROW()
Returns the position of the top row of the formatted area of a window
------------------------------------------------------------------------------
Syntax
WFROW([<lRelative>]) --> nValue
Argument
<lRelative> Designates an optional parameter. If this parameter is
.T., then the function returns the absolute value of the difference
between WROW() and WFROW().
Returns
The function either returns the position of the top row of the formatted
area within a window, or the difference between the outer border and the
formatted area of a window.
Description
This function is particularly useful if information in a window must be
saved to a file. Four functions (WFCOL(), WFLASTCOL(), WFROW(),
WFLASTROW()) allow you to establish the coordinates of the formatted
area of a window. This information can be saved for later use.
In order to avoid complex calculations, you can determine the difference
between the outer border and the formatted area of a window when you use
the optional logical parameter. You can transmit this value later when
you use the WFORMAT() to restore the old value.
Note
. When used in Window 0, the function returns the value for
WBOARD().
Example
Every WFXXX() output corresponds to the currently selected window.
Please notice that WBOX() corresponds to WFORMAT(1, 1, 1, 1):
CLEAR
WOPEN(10, 10, 20, 70)
WBOX()
? WFROW(), WFROW(.T.) // 11, 1
? WFCOL(), WFCOL(.T.) // 11, 1
? WFLASTROW(), WFLASTROW(.T.) // 19, 1
? WFLASTCOL(), WFLASTCOL(.T.) // 69, 1
INKEY(0)
WCLOSE()
RETURN
