Google Web APIs - Actionscript 3 library (v2.1)

When you find bugs or errors, please fill in an issue (under 'Issues'-tab)

About

The library is a simple collection of Google's API features, there is a class per feature, like Google Web search, Images Search, Google Suggest etc. Each library throws it’s own event with an Array or Value Object of matching datatype(s), for example GoogleWebItem, so it’s easy to keep track on wich data is recieved and what this data contains, giving the developer transparency using Intellisense.

Little example code

var googleWebSearch:GoogleWebSearch=new GoogleWebSearch();
googleWebSearch.search(txtInput.text,0,"nl");
googleWebSearch.addEventListener(GoogleApiEvent.WEB_SEARCH_RESULT,onWebResults) ;

//If you want to catch the API errors yourself:
googleWebSearch.addEventListener(GoogleAPIErrorEvent.API_ERROR,onAPIError)

private function onWebResults(e:GoogleApiEvent):void{
	var resultObject:GoogleSearchResult=e.data as GoogleSearchResult
	trace("Estimated Number of Results: "+resultObject.estimatedNumResults)
	trace("Current page index: "+resultObject.currentPageIndex)
	trace("Number of pages: "+resultObject.numPages)

	for each (var result:GoogleWebItem in resultObject.results){
		trace(result.title, result.url)
	}
}

private function onAPIError(evt:GoogleAPIErrorEvent):void{
	trace("An API error has occured: " + evt.responseDetails, "responseStatus was: " + evt.responseStatus);
}
