public class SuggestBox
extends Composite
implements HasText, HasFocus, HasAnimation, HasEnabled, SourcesClickEvents, SourcesChangeEvents, SourcesKeyboardEvents, FiresSuggestionEvents, HasAllKeyHandlers, HasValue<java.lang.String>, HasSelectionHandlers<SuggestOracle.Suggestion>, IsEditor<LeafValueEditor<java.lang.String>>

A SuggestBox is a text box or text area which displays a pre-configured set of selections that match the user's input. Each SuggestBox is associated with a single SuggestOracle. The SuggestOracle is used to provide a set of selections given a specific query string.

By default, the SuggestBox uses a MultiWordSuggestOracle as its oracle. Below we show how a MultiWordSuggestOracle can be configured:

   MultiWordSuggestOracle oracle = new MultiWordSuggestOracle();
   oracle.add("Cat");
   oracle.add("Dog");
   oracle.add("Horse");
   oracle.add("Canary");

   SuggestBox box = new SuggestBox(oracle);
 
Using the example above, if the user types "C" into the text widget, the oracle will configure the suggestions with the "Cat" and "Canary" suggestions. Specifically, whenever the user types a key into the text widget, the value is submitted to the MultiWordSuggestOracle.

Note that there is no method to retrieve the "currently selected suggestion" in a SuggestBox, because there are points in time where the currently selected suggestion is not defined. For example, if the user types in some text that does not match any of the SuggestBox's suggestions, then the SuggestBox will not have a currently selected suggestion. It is more useful to know when a suggestion has been chosen from the SuggestBox's list of suggestions. A SuggestBox fires SelectionEvents whenever a suggestion is chosen, and handlers for these events can be added using the addSelectionHandler(SelectionHandler) method.

public void setValue(java.lang.String newValue)
Description copied from interface: HasValue
Sets this object's value without firing any events. This should be identical to calling setValue(value, false).

It is acceptable to fail assertions or throw (documented) unchecked exceptions in response to bad values.

Widgets must accept null as a valid value. By convention, setting a widget to null clears value, calling getValue() on a cleared widget returns null. Widgets that can not be cleared (e.g. CheckBox) must find another valid meaning for null input.

Specified by:
setValue in interface TakesValue<java.lang.String>
Specified by:
setValue in interface HasValue<java.lang.String>
Parameters:
newValue - the object's new value
See Also:
TakesValue.getValue()

setValue

public void setValue(java.lang.String value,
                     boolean fireEvents)
Description copied from interface: HasValue
Sets this object's value. Fires ValueChangeEvent when fireEvents is true and the new value does not equal the existing value.

It is acceptable to fail assertions or throw (documented) unchecked exceptions in response to bad values.

Specified by:
setValue in interface HasValue<java.lang.String>
Parameters:
value - the object's new value
fireEvents - fire events if true and value is new

showSuggestionList

public void showSuggestionList()
Show the current list of suggestions.


onEnsureDebugId

protected void onEnsureDebugId(java.lang.String baseID)
Description copied from class: UIObject
Called when the user sets the id using the UIObject.ensureDebugId(String) method. Subclasses of UIObject can override this method to add IDs to their sub elements. If a subclass does override this method, it should list the IDs (relative to the base ID), that will be applied to each sub Element with a short description. For example: Subclasses should make a super call to this method to ensure that the ID of the main element is set. This method will not be called unless you inherit the DebugID module in your gwt.xml file by adding the following line:
 <inherits name="com.google.gwt.user.Debug"/>

Overrides:
onEnsureDebugId in class UIObject
Parameters:
baseID - the base ID used by the main element

showSuggestions

void showSuggestions(java.lang.String query)
