1024 text characters

Version 3.0 and earlier

4 list boxes

1024 text characters

MORE INFORMATION

Items that can take or return arguments are items that either read some value from the initial/result column of the dialog definition table, write some value to the initial/result column, or both.

Combination and Linked list boxes accept and return values through their linked text edit boxes. Most of these list boxes also accept and return a list index value in the initial/result column. Therefore you would count the list box and the text edit box associated with it as separate items. The exception to this is the Linked drive and directory list box, and the Directory text box (items 19 & 20 Windows only). These boxes ignore the initial/result column.

The following items can take or return arguments:


Item
Number    Item
--------  --------------------------------------------------------
 
6         Text edit box
7         Integer edit box
8         Number edit box
9         Formula edit box
10        Reference edit box
11        Options button group
13        Check box
15        List box
16        Linked list box
18        Linked file list box (Windows only)
21        Drop-down list box
22        Drop-down combination edit/list box
