oCol:bExtend.
If specified, this codeblock is evaluated with column object as parameter. If the result is zero, the cell is painted normally. If the result is > 0, this cell width extends to that many cells on the right side.
Also if some cells in an array contain codeblocks, these are evaluated with newvalue, array, row, col as parameters and result is displayed in this cell.
Sample code:
- Code: Select all Expand view RUN
- #include "fivewin.ch"
function Main()
