Progress 4GL Reference

INNER-LINES attribute

The number of data lines within a combo-box drop down list, editor widget, or selection list.

Data type: INTEGER

Access: Readable/Writeable

Applies to: COMBO-BOX widget, EDITOR widget, SELECTION-LIST widget

For combo boxes, this attribute has meaning only in Windows.

This attribute is more portable than the HEIGHT-CHARS attribute. For combo boxes, the value must be 3 or greater.

If a selection list or combo box is not already realized and you reference its INNER-LINES attribute, Progress realizes the widget.
