Designer: Each choice list has its own window. Window structure members are set to default values inside the Designer. You can modify these values, either in the Designer (see the Designer User's Guide for more information), or in your code, after you have read the form from the Designer library.
Code: Each choice list has its own window. The window is copied from the default choice list window. The default choice list window is initially defined in vv_init() with a single-line border, a window attribute of LCLINACT, and right and left column margins of one. The size and placement of the window is not determined until the choice list is displayed by the function attached to the Choice List key. If you set CLMANUAL for the choice list, the choice list size and appearance must be set before the user can pop up the choice list.
