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
-
The NSArray containing the elements of the list. For example, colleges could name the array containing objects that represent individual schools.
- item
-
The identifier for the elements of the list. For example, aCollege could represent an object in the colleges array.
- value
-
The value to display in the selection list; for example, aCollege.name for each college object in the list.
- selection
-
An NSArray of objects that the user chose from the selection list. For the college example, selection would hold college objects. Since a WOPopUpButton lets the user select only one item at a time, this array holds no more than one item.
- name
-
A 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.
