Synopsis
WOPopUpButton { list=anArray; [item=anItem; value=displayedValue;] [selection=theSelection;] [name=fieldName;] [disabled=YES|NO;] ... };
Description
WOPopUpButton displays itself as a selection list that allows the user to select only one item at a time. The related element WOBrowser is similar to WOPopUpButton except that it allows the user to select more than one item at a time.
- list
- Array of objects from which the WOPopUpButton derives its values. For example, colleges could name the array containing objects that represent individual schools.
- item
- Identifier for the elements of the list. For example, aCollege could represent an object in the colleges array.
- value
- Value to display in the selection list; for example, aCollege.name for each college object in the list.
- selection
- Object that the user chose from the selection list. For the college example, selection would be a college object.
- name
- Name that uniquely identifies this element within the form. You can specify a name or let WebObjects automatically assign one at runtime.
- disabled
- If disabled evaluates to YES, this element appears in the page but is not active. That is, selection does not contain the user's selection when the page is submitted.
