Description
The LISTBOX SET LOCKED COLUMNS command locks numColumns columns (starting from the first on the left) in the list box designated by the object and * parameters.
Locked columns are shown in the left part of the list box and do not scroll with the rest of the list box columns. For more information, refer to the Design Reference manual.
If you pass the optional * parameter, this indicates that the object parameter is an object name (a string). If you do not pass this parameter, this indicates that the object is a variable. In this case, you pass a variable reference instead of a string.
In numColumns, you can pass any value included between 1 and the total number of columns in the list box minus 1. For a list box with X columns, if you pass a value > X-1 in numColumns, it will be reduced automatically to the value X-1.
To remove the column locking, pass 0 or a negative value in numColumns.
