Description
WOBrowser displays itself as a selection list that displays multiple items at a time. The related element WOPopUpButton is similar to WOBrowser except that it restricts the display to only one item at a time.
- list
- Array of objects from which the browser derives its values. For example, colleges could name the list 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.
- selections
- Array of objects that the user chose from list. For the college example, selections would hold college objects.
- 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, selections won't contain the user's selection when the page is submitted.
- multiple
- If multiple evaluates to YES, the user can select multiple items from the list. If NO, the user can select only one item from the list. The default is NO.
- size
