The function was successful.

< 1

An error occurred. Refer to Return Codes.


When a tool is invisible, other tools in the toolbar are arranged so that no gaps are left, and so that their order is maintained (left-to-right and top-to-bottom, just as text would wrap).

Before calling this function, you must declare a variable of data type L_BOOL. Then, pass the address of the variable in the pfVisible parameter. This function will update the variable with TRUE or FALSE.
