twGet( nRow, nCol, _wGetBlk, _wGetName, GetList,;
_wGpicture, _wGcolor, wWhenBlk, wValidBlk )
----------------------------------------------------------------------------
Add a GET object to the current getlist. In this version, the
RANGE clause is not implemented. You can get the required result
in a VALID. This function was added at the request of users. It
offers the basic range of options in the Clipper GET system. The
display attribute is defaulted to the current window text colour,
ie., the active GET is displayed in the enhanced colour and
inactive ones in the unselected colour. Code blocks are passed to
avoid macro operations within the library. See FIELDBLOCK() in the
Clipper documentation for a description of GET/SET blocks.
Arguments:
Unless the FIRST FIVE parameters are passed, this function does
nothing!
nRow - 'N' Relative Window Row.
nCol - 'N' Relative Window Column.
_wGetBlk - 'B' Get/Set Code Block.
_wGetName - 'C' Get Variable Name as string.
GetList - 'A' Current getlist. You can't add to your LOCAL
getlist unless you pass a reference to it.
wGpicture - 'C' Clipper Picture String.
wGcolor - 'C' Clipper Colour String.
wWhenBlk - 'B' GET PreBlock.
wValidBlk - 'B' GET PostBlock.
Return:
Current Window Handle
Example:
GetTry1 := SPACE( 10 )
twGet( 4,9,{|cVal| IIF(cVal == NIL, GetTry1, GetTry1 := cVal)}, ;
"GetTry1", ;
GetList, ;
REPL( "9", LEN( GetTry1 )),,, ;
{|| !( "9" $ GetTry1 )} )
Places a GET on the screen at relative window coordinates 4, 9
allowing digit entry with a user defined function called during
validation.
