Actionscript 3 :: Handle Event For Nonvisual Objects In Flex?
Nov 7, 2011
I am trying to perform two way binding e.g I have a button (out of many controls), on its selection, I am showing the values of its diff properties(like height, width etc) in some textinput. This one way process works fine.But the reverse process doesn't work. i.e When I select some button, and try to change its dimension by entering some value in height, width textinputs, the dimension are not changed.
private void Form1_Load(object sender, System.EventArgs e)
{
//Create some data and bind it to the grid
I want to handle the mouseevents for all the sprites on the stage including the one those are hidden behind (or overlapped or occluded) and the main condition is that I want to handle the occluded sprite (that hidden behind other sprite). example, say I have sprite1 and sprite2 on stage and I want to start drag whenever i click on the sprite and stop drag after another click.
This can be done easily, but the problem and my main requirement is that if I drag the sprite1 and drop it exactly on top of the sprite2 then sprite2 will be hidden behind the sprite1 I wont be able to drag the sprite2 without moving the sprite1 first. if you have played zynga's empires and allais game on facebook, it is handled seperatly, it is how it works in that game, the mouse event is triggered on the sprite behind the overlapping sprite, if you have two sprites overlapping one sprite than the mouse event is triggered on the sprite which is last and not the one in front irrespective of whether there is only one sprite overlapping or two or three and this happens to irregular shaped sprites (not just rectangles)
I want to know, Is there any way to handle or control the shockwave objects in flash by using 'as3'? I know this is possible in 'Director' by using 'Lingo'. But I am not able to find any way or any articles from where i can get some idea about this. In the director, I've seen there is way to set some properties like camera position, light affects etc. with the shockwave objects. But I am not sure about the FLASH. Can it possible to use these type of properties with shockwave objects in flash, which could be controlled in action script3 ?
I'm coding a website in pure AS3 using FlashDevelop and have an object that loads an XML file on init. Is there a good way to make my main function wait until it has finished loading? I know about onComplete events and how to use them internally in the object but I'm not sure how to proceed.
I have an object being passed between flash and flex using the a custom event. I am importing a library in flex containing a copy of the object's class. The classes are identical. But when I attempt to access the object in flex I get this error: TypeError: Error #1034: Type Coercion failed: cannot convert com.cackleberries.data.api::ApiObject$ to com.cackleberries.data.api.ApiObject.
This function is passed into flash as a callback from AIR / flex public function airEventHandler(type:String, data:Object):void { switch(type) { case "air_api_call": if(data) { if(data.hasOwnProperty("apiObject")) [Code] .....
I am getting the error when I pass the apiobject to serverApi.makeApiCall. That function takes a ApiObject as its parameter. Initially, the data object is created with with the apiObject key with a ApiObject as the value (done in flash).
I'm running a recursive function which in the worst case senario is of factorial order. (i.e: runs itself n! times)As soon as n exceeds 7 in these worst case senario's the function times out (Error #1502). I want to handle this error event so that the user can be presented with an error that the problem is too complex.I don't want to extend the timeout period as 15 seconds is reasonable.
I've a flash site 100x100% in browser window. When I open new tab in browser window Event.RESIZE doesn'tdispatched.how to handle this event except EnterFrame or Timer listeners?
I am working on integrating the social network "vkontakte" into my desktop application using Adobe AIR. The flow of authorization in the app is as follows:
Open the web browser with a url, and when the user inputs login and password, redirect to somePage.html. From that URL, I need to get an access_token to sign all future API requests.
So the question really is: How can I listen to an event, which will indicate that the user has logged in successfully, or failed to get that access_token?
Does addEventListener(ErrorEvent.ERROR, handler) handle all type of error event, for example, IOErrorEvent.IO_ERROR, SecurityErrorEvent.SECURITY_ERROR, and other all error events? I'm looking for addEventListener() version of try catch(e:Error)(e:Error can catch all type of errors).
You got an eventlistener for an object that can dispatches events in intervals of 0.2ms.And if the eventhandler would need 0.5ms for his operation, what would happen? (listener and handler are in the same class).Would the last event overwrite the event before? In my case, I get some data from a xmlSocket, and I thought, that some datastrings can come in quicker than to work it off in my handler.
How does flash player handle objects when they are no longer on the visible stage? Is the graphical data still in memory? Does hittestobject/point consider them? Are enterframe and interval events still running?
In AS2 I would hold metaobjects (minimal x,y,width,height data) that would delete/create movieclips as the screen scrolled. Is this still a correct approach in AS3? If not, is there anything I can do to offstage display objects that improves efficiency, assuming around 400 are created initially?
I'm not sure if it's possible, but can you override a variable of a parent class like you can override a function? I'm trying to create my own event class that can handle the target property. I have a custom imageLoader class, but when it dispatches it's loading complete event:
ActionScript Code: dispatch(new Event("load_complete")); and a listener picks it up, e.target = null where I would like e.target to equal the imageLoader instance that has finished loading.
Does anyone have an answer or a better way to accomplish what I am aiming for?
If I plan to implement 100 objects on stage to be listen to mouse and keyboard input, is using "function" call responsive enough? How good does eventlistner work?
I have a couple of Sprites on my screen and I want to write a single event handler to handle the double click on any of those Sprites. The following approach works for every event type except DOUBLE_CLICK:
[Code]...
To make it work, because in my application I will have lots of Sprites. In my opinion, a single event and the target property are more efficient than hundreds of event listeners. Am I right or should add event listeners to every Sprite?
I have an mxml file called HomeView.mxml in a mobile app built using Flash Builder 4.6. In that HomeView.mxml I have an HSlider, which is dispatching events when the thumb is moved. What I'm trying to do is to listen for that valueCommit event in an .as file elsewhere in the project.
Whenever the thumb moves, an event is dispatched in HomeView.mxml:
private function commitHandler(e:FlexEvent):void { trace("committed!"); }
But this code never runs. I do have a handler in the HomeView.mxml file which handles the event, but for other reasons I need to handle it in view.as as well.
I'm creating a scrollbar gallery from a tutorial on this site. Though I've completed the tutorial, and customised the gallery to my own needs, however I'm trying to make a very small change to it - and no matter what I do, keep running into problems. I'm trying to replace the rectangular handle with my own customised handle - a (20 x 20) 'circular' png image that I've imported into Flash, made a graphic and stored in the library (though I understand it can be imported using actionscript, like the other images in the gallery).
I'm developing an AIR application with Flash Builder 4 Beta 2 (nightly SDK) an am not using a framework like mate. I have a couple of views and components in my application. An outline might look like this:
I have a Flex login page that uses HTTPService to communicate with server side php script. Once user's credential is verified, a session will be created and the login page will redirect to the main Flex page with that session info. I'm not sure how to implement the session logic.
I have a Flex application with three different views. Only one view is shown at a time, and the choice of view depends on what part of the application the user is working with. If it had been an ordinary HTML webapp I would have created three different HTML-templates/pages for each view.
What is the recommended way to handle such application views in Flex?
I am thinking about porting my social netowrking site code to Adobe Flex / PHP and was wondering how does one go about handling sessions in this case. I would imagine Adobe Flex doesn't really know if a PHP session has been started or not therefore, I would have to research how to accomplish this. One idea I had was to created a session token string after a successful login and pass this token to each http request the user makes for data. E.g. [URL]. Each time a request is made to this page, a MySQL query is run to check if the token I passed in the url matches against the token created for that user during login. If this is true, then data is returned.
In ACE Flex 3 , there is a topic "Handle Framework Events". Any document which lists all the 'required' framework events for ACE test? So I could know what are "framework" events and will focus on them.
I do not know why but I see that itemclick event on a menubar do not fired unless you click a sub item. What is the clean way to handle clicks on menuitems which are on the top level and do not have sub menu items. For example I want to fire an event whenever MenuItem B is clicked.
I've got a problem while migrating my TabNavigator from Flex 3 to Flex 4.5. Stripped to the bare minimum, the following code will produce the bug, namely that the second child of the TabNavigator fails to be created properly:
I am trying to send a simple HTTP message from Flex to C# server, but it seems that I am getting tow calls, first is the real one and the second is an empty one.
Why is that and how can I handle it?
This is my C# code:
TcpListener listener = new TcpListener(IPAddress.Any, 9400); listener.Start(); Console.WriteLine("Server started");
[Code].....
I been trying to send a true HTTP response a notice another thing, the second call is coming without waiting for the first call, if I am putting the response thread to short sleep(100 milliseconds in my test) then I am getting the second call before I been able to response for the first one.
I have editable grids which are 2-way binded to my model. What I want is to validate my data when user edits any cell before it get updated in model. I have applied my validation at ItemEditEnd handler, but, I want to apply validation in between itemEditBegin and itemEditEnd events.
