I have a tab navigator defined in MXML, with two tabs.In each tab, I have some buttons. I have used ActionScript to add event listeners to all the buttons, and they work for the buttons that are visible (and in the currently "active" tab) when I load my Flex 4.5 AIR application.However, I get an AIR error for the event listeners attached to the buttons in the second tab.Here's the crucial part of the error:TypeError: Error #1009: Cannot access a property or method of a null object reference.
printableInvoice.addEventListener(batchGenerated, printableInvoice_batchGeneratedHandler);Results in this error: 1120: Access of undefined property batchGenerated. I have tried it as FlexEvent.batchGenerated and FlashEvent.batchGenerated.
The MetaData and function that dispatches the even in the component printableInvoice is all right. It I instantiate printableInvoice as an mxml component instead of via action-script it well let put a tag into the mxml line: batchGenerated="someFunction()
All my other instances I can access on my main movie from within my main movie except my button named play_game. Whenever I tried to trace or access it, it says its null. Do I have to do something special in order to access button instances?
I'm trying to create an Event Listener used with all buttons placed on the stage rather than a listener for each button object.Are coding examples of a class listener?
I'll keep this simple (I hope). There's a button with an event listener on a frame of the main timeline. You click the button to go to the next frame and a movie clip plays. The instance of that button doesn't exist on that next frame. Does the event listener for the button automatically get removed when you go to that frame since the button doesn't exist there?
The movie clip is set up to send the main timeline back to the previous frame when it's finished and my event listener seems to vanish when I go back to that frame.
I'm creating a minesweeper game as my first flash project, but I'm already stuck on something technical. I have created a button named Button which contains a bitmap. I have a lot of instances of that button on stage, and they are put there by actionscript using a for-loop. Their instance names are button0, button1, button2, button3, etc.
This is the code for the eventlistener: It's in the first keyframe of the actions layer. var buttonListener:Object=new Object(); buttonListener.click=function(evt:Object):Void{ trace("clicked"); } for (i=0; i<rows*cols; i++) { eval("button"+i).addEventListener("click", buttonListener); }
I also noticed that when I do this for one button that I created myself and put on the stage manually, this also doesn't work, but when I pick one of the predefined buttons, it works just fine.
isit possible to call two functions from one button event listener?
or is it even possible to write two seperate listeners for one button that listen for the same thing an example is shown in the code;
also, i have string variable, that i want to use to call a certain funtion depending on the variable, for example the vairables name is phase_no can i do next_btn.addEventListener(MouseEvent.CLICK,nextPhase,beginSubmit+phas e_no)??
Is there any way in AS2 to add an event listener NOT to a particular button instance in the stage, but to any symbol in the stage which is a Button?[code]...
I have this Accelerometer event, taken from the code snippets, and it works fine, but i would like to know is it possible to turn this off by a button.
I have a set of buttons on, and what i would like to do is change the value of a variable, depending which button you are over.i know i could do this by writing an event listener and a function for each button, but this is too time consuming.I'm sure in the old days it would have been as simple as if btnwhatever.mousedown = true then.... but now i have no idea.
I would like to know if it is possible to pass a clip event on to both the function that has a listener, and to the button that is being pressed. I am finding the listener takes it and thus the button doesn't see it.I found a walk around, however, I'd like to know if it is possible say for one clip event to be seen by both objects?For example, with the mouse over a button the listener function detects the event and carries itself out, however, the button misses the event now.
Whenever I remove an event listener to a button then that button no longer works. Does it cause memory leaks to not remove these listeners.....come to think of it I have about 30 eventListeners that I cannot remove otherwise the application ceases to function correctly. Is my application a memory black hole? How should i proceed with garbage collection?
I have a situation where I'm calling a function with an event listener attached to a button, which in turn calls a function, which does a number things including calling a second function which resides in a child swf.
Just as an example: Code: myBtn.addEventListener(MouseEvent.CLICK, firstFunction); function firstFunction(e:MouseEvent):void{ //I call another function in here (among other things) externalSwf.stopTimer(); }
"StopTimer" resides in an external swf which for our purposes is called externalSwf and it resets a running timer. Code: function stopTimer():void{ myTimer.reset(); }
I'm getting argument mismatch errors, which often have to do with the Event Objects not matching. The event object for firstFunction is a mouse event triggered by a click so I put in e:MouseEvent...what I don't clearly understand is, what type of object event is dispatched when I call the function stopTimer from inside the function firstFunction?
On the main timeline, I have placed a movieclip (movieclipone) which contains some content. On frame 85 of movieclipone, there is a new keyframe which contains a movieclip that hasn't previously appeared in the movieclipone timeline, (moviecliptwo) which contains four buttons (btnone, et cetera).Is there a way to have code in the main timeline that attaches listeners to the buttons inside moviecliptwo, which, when pressed, trigger a function that increases a counter and tells movieclipone to go to the next frame? This is the code I am using right now:
Im getting an error whilst trying to add an event listener to a class of a Button on my stage.
1061: Call to a possibly undefined method addEventListener through a reference with static type Class.
On my stage i have a Button with the instance name stopBtn, this is also exported to an actionscript class called classes.stopBtn (stopBtn.as in a folder called 'classes'). The button is on the first keyframe in the main timeline, in a layer with other buttons on that layer
I'm trying to sync animation to music at a specific BPM. I've tried using the Timer but it isn't accurate when dealing with small intervals in milliseconds. I did some reading and found an alternate method that uses a small silent audio file and the SOUND_COMPLETE event as a Timer.[code]...
I got a reference to an arrayCollection and add event listener like this: collection.addEventListener(CollectionEvent.COLLECTION_CHANGE, onCollectionChange); That's fine. Now some other component does have the same reference and is adding items to and removing items from that collection.
Each time the handler is called: private function onProjectPersonsChange(event:Event):void { if (event.kind == CollectionEventKind.ADD) { //do something } else if (event.kind == CollectionEventKind.REMOVE) { [Code] ..... Why the removed item is not in 'items'?
In our app, I am periodically noticing that a particular event handler is not firing. 99% of the time, it works fine, but, every so often, it just dies. How can I find out whats happening? Is the DispatchEvent() not happening/working somehow? Is my listener still listening? Did something else catch the event, and not pass it along so that the 'right' listener can get to it ?
Here's a little bit of the code...
Thats a somewhat pruned down version of what the real code is, but I don't think I trimmed out anything important. The key, as I see it is that we fire up the params dialog, then start to listen for the closed event. Then, we show the param dialogs close function. What happens when it fails is that the trace message "caught close event.." is never generated, and, consequently, the closeHandler is not getting called at all.
let's say that i have this button which is called "Click_Here" and i added an event listener to it in some class file in order for it to run the event handler in a different one .. so it will be like this
We have a flex application that connects to a proxy server which handles authentication. If the authentication has timeout out the proxy server returns a json formatted error string. What I would like to do is inspect every URLRequest response and check if there's an error message and display it in the flex client then redirect back to login screen.
So I'm wondering if its possible to create an event listener to all URLRequests in a global fashion. Without having to search through the project and add some method to each URLRequest.
TypeError: Error #2007: Parameter listener must be non-null.at flash.events::EventDispatcher/removeEventListener() at project1_fla::MainTimeline/btnName()
I'm trying to call an event I've created in another component. I've added trace() into my methods so I can see what's being called. Everything except for the event listener (myEvent) is being called.
I know I can create a custom event and associate data with it and retrieve it in respective Event Listener. But What I am interested to know is, is there a short method (without having to extend Alert Event Class) to associate parameters to its alert Listener.
This doesn't work. creationComplete is not called until the repeater has finished instead of (as I expected) when the creation of the button is complete. I'm not sure how to accomplish this.
BTW - I also tried placing the creationComplete on the parent component to the repeater, but it would only be called the first time the component was rendered (the data inside the repeater sometimes changes) so that didn't work.
I am writing a web application that will serve as a configuration for a random data generator that I have written in Java.The values that I set in this application will write to xml. The xml data is updated by a file called simulationParams.as and that file is added to each child in the "viewStack" so that when I change any of those values the simulationConfig file will be automatically updated.The problem is that when I press the randomizeBtn the proper events are fired and the listeners grab those events.My problem exists when I uncheck the randomize button.For some reason an event is triggered or the listener isnt listening so that when I uncheck randomizeBtn the values go back to their last position or value on the slider. Ex. if my initial value is 0 then press randomize the slider will go to 100. The config file updates and all is well.When I uncheck the randomizeBtn, the sliders value goes back 0 but the config file isnt update.The same thing happens when I press the useDefaultBtn for both selected/unselected, nothing gets updated.[code]
