Choice (SAS AppDevStudio API Developer Documentation for Java)

public class Choice
implements com.sas.collection.ContentsChangedListener, com.sas.lang.StringDataInterface, com.sas.PublicClonable, ResizeToFitInterface, com.sas.ViewDefaultModelInterface
implements com.sas.collection.ContentsChangedListener, com.sas.lang.StringDataInterface, com.sas.PublicClonable, ResizeToFitInterface, com.sas.ViewDefaultModelInterface

Choice is a component that maintains a dropdown list of items for selection.

Creation:

Create a choice

Choice choice1 = new Choice();
choice1.initialize();

Default Size:

height = 23
width = 124

Required Interfaces:
Choice requires a model that implements com.sas.collection.StaticOrderedCollectionInterface. A default model is automatically created and attached to the choice when the Choice is initially constructed.

Events:
The Choice sends out an ItemEvent when an item is selected in the dropdown list.

Notes:

Choice implements the com.sas.Collection.ContentsChangedListener, com.sas.PublicClonable, com.sas.lang.StringData, and the com.sas.visuals.ResizeToFit interfaces.
The resizeToFit property determines whether to change the size of the Choice when either the items in the list change or the font changes. If the resizeToFit property is set to true, changing the items or font may cause the Choice to expand or contract. The resizeToFit property is initially set to false. The resizeToFit property determines whether to change the size of the component when either the text or font changes. If the component is managed by a layout manager that uses preferred sizes, the component will behave as if the resizeToFit property has been set to true regardless of the actual value of the resizeToFit property.
Transforms are used when the information in the model needs to be changed to a different type to be used for output, input, or display.
The items in the dropdown list can be modified (additions, insertions, removals) only if the attached model implements the OrderedCollectionInterface.
Modifying Items in the Choice Dropdown List
- Items can be added to the end of the list through the add(String), add(Object),addItems(Enumeration) and add(Object[]) methods. A null item can be added to the list if a display transform is applied that returns a non-null value.
- An item can be inserted in the dropdown list through the insert(String, int index) or insert(Object, int index) methods. Specifying an index of less than 0 or an index greater than (current item count - 1) will result in a java.lang.IndexOutOfBoundsException being thrown. A null item can be inserted into the list if a display transform is applied that returns a non-null value.
- An item can be removed from the dropdown list through the remove(String), remove(Object) or remove(int index) methods. Specifying an index of less than 0 or an index that is greater than (current item count - 1) will result in a java.lang.IndexOutOfBoundsException being thrown. Specifying an item that is not in the list will result in a java.lang.IllegalArgumentException being thrown.
Items in the dropdown list can be selected by using the select(int index), select(String), setSelectedItem(String), setSelectedItem(Object), setSelectedIndex(int index), or setText(String) methods. Specifying an index that is greater than (current item count - 1) will result in a java.lang.IllegalArgumentException being thrown.
Specifying an item that is not in the list will deselect the current selected item.
Specifying a null value(setText(null) or setSelectedItem(null)) or select(-1) will cause the Choice to be cleared of a selected item.
