猿パッチを適用するために私のdecorator関数をカスタムウィジェット（dijit/form/Selectに基づいて）に変換することが可能かどうかを知りたいと思います。DOJOのデコレータをカスタムウィジェットに変換しますか？
または代替ソリューションをご存知ですか？このanswerから採取
require([
'dijit/form/Select',
'dojo/_base/window',
'dojo/domReady!'
], function(Select, win) {
var decorator = function(select) {
select.on('change', function(value) {
alert(value);
});
select.dropDown._onUpArrow = function() {
this.focusPrev()
}.bind(select.dropDown);
select.dropDown._onDownArrow = function() {
this.focusNext()
}.bind(select.dropDown);
select.dropDown.focusNext = function() {
var focusNext = function() {
var next = this._getNextFocusableChild(this.focusedChild, 1);
this.focusChild(next);
if (next.option.group) {
focusNext();
}
}.bind(this);
focusNext();
}.bind(select.dropDown);
select.dropDown.focusPrev = function() {
var focusPrev = function() {
var prev = this._getNextFocusableChild(this.focusedChild, -1);
this.focusChild(prev);
if (prev.option.group) {
focusPrev();
}
}.bind(this);
focusPrev();
}.bind(select.dropDown);
select.dropDown.onItemHover = function(item) {
if (item.option.group) {
item._set('hovering', false);
return;
}
if (this.activated) {
this.set('selected', item);
if (item.popup && !item.disabled && !this.hover_timer) {
this.hover_timer = this.defer(function() {
this._openItemPopup(item);
}, this.popupDelay);
}
} else if (this.passivePopupDelay < Infinity) {
if (this.passive_hover_timer) {
this.passive_hover_timer.remove();
}
this.passive_hover_timer = this.defer(function() {
this.onItemClick(item, {
type: 'click'
});
}, this.passivePopupDelay);
}
this._hoveredChild = item;
item._set('hovering', true);
}.bind(select.dropDown);
select.dropDown._onItemFocus = function(item) {
if (item.option.group) {
return;
}
if (this._hoveredChild && this._hoveredChild != item) {
this.onItemUnhover(this._hoveredChild);
}
this.set('selected', item);
}.bind(select.dropDown);
};
var select = new Select({
