Combobox Control Properties

The items are arranged in alphabetical order.

Item Significance
? Allows you to enter text that will be displayed in a ToolTip when the user pauses the mouse pointer over the control.
Field properties... Displays the edit control properties panel (because a combobox actually consists of an edit control and a listbox).

The properties of the integral edit control associated with a combobox are nearly identical to those of an edit control.

List definitions:

List contains...

Displays a popup that collects the values you want to display in the list.  These are contained in a VALUE clause in the panel copybook.
List definitions:

Number of elements in list

Specifies the maximum number of entries the list may contain.  If the control is too small to display the entire list, it will provide scrollbars.

Note:  Windows 9x limits this control to a maximum of 8,160 items, or 32K of data; whichever is less.  If you need to display more items than this, you should consider using a listview.

Presentation:

Sort the list when displayed

Presents the data in the list sorted in ascending order when the list is displayed.
Combobox type:

Edit control with list always present

Displays an edit control with a list beneath it.
Combobox type:

Edit control with a dropdown list

Displays an edit control with a list which is collapsed when the field does not have the focus, but which shows when appropriate.
Combobox type:

No edit control; only a dropdown list

Displays a list which is collapsed when the field does not have the focus, but which shows when appropriate.
