Flex :: Getting A Hold Of The Application To Call Its Method?
Sep 12, 2011
In my Flex 4.5 application I have a TitleWindow Settings.mxml, which is popped up by the PopUpManager.Once the user has changed some settings, I not only need to save them to a SharedObject, but also to apply them to the main Application itself - so that the changes are visible to the user immediately.For example I need to call its method hideApp(somevalue);
The spark.components.Application does not seem to have any static/singleton methods to get ahold of it.So how do you do it? how to declare, that an MXML file implements one or several interfaces?
package {
public interface Hiddable {
function hideApp(value:Number):void;[code]....
besides the main Application I have a SettingsTest.mxml Application in my project for"unit testing" that particular functionality.
I would like to learn Adobe Flex mobile development.I have created a new project called SampleProject, then I got SampleProject.mxml in default package and SampleProjectHomeView.mxml.[code]How can I call the add and sub methods from the class above in SampleProjectHomeView.mxml?
I need it in FlexUnit to test private methods. Is there any possibility to do this via reflection by using describeType or maybe flexUnit has some build in facility? I dislike artificial limitation that i cannot test private functions, it greatly reduces flexibility. Yes it is good design for me to test private functions, so please do not advise me to refactor my code. I do not want to break the encapsulation for the sake of unit testing.
I have a quite different problem with resizing. I have a Flexbook component which uses the middle part of screen (center) with a html header menu and footer. The problem: The scaling works perfectly when we run in the local machine ( Flexbuilder). But when we deploy it to the server its like scaling never existed.. The requirement: when user maximizes the window or minimizes it, the Flexbook should be resized to fit the screen.
How can i call a CGI script in flex 3? Also how can i retrieve the result of exection of that cgi script?
For example, lets say my CGI script(hello.cgi) just display "hello world". How can i call this script from flex 3 and then retrieve the result, i.e. hello world , so that it can be displayed on my flex application.
In my application I have a viewstack which I am changing via actionscript using the selectedChild attribute. The problem I run into is that I want to call a method in the component that is now the selected child in the viewstack, right after I assign it to be the child it gives me a "Cannot access a property or method of a null object reference." Is there some way that I can make this work without changing the creationPolicy to all?
Actionscript:
public function displayTaskDashboard(evt:Event):void { pm_viewstack.selectedChild = nc_taskDashboard; taskDashboard.populateTasks(Globals.currentProject.Project_ID);
I am using RemoteObjects to call ZendAMF PHP from Flex/Flash Builder 4.6. I want to stop or abort a method call before it sends the request to the server based on an event or similar.
I have a class where I create and store all the RemoteObjects - for example:
activityLogService = new RemoteObject("zend"); activityLogService.endpoint=endpointServer; activityLogService.addEventListener(FaultEvent.FAULT,faultHandler);
Then later I can simply call this object:
remotingService.activityLogService .getRecords();
I am trying to find a way in my remotingService object to stop the request - and not send anything to the server - for example if some variables are not set properly.
I noticed there is an invoke event: activityLogService.addEventListener(InvokeEvent.INVOKE,invokeHandler);
However, I can not tell if that's going to stop things at the proper point, or if it's even possible to actually STOP the request - if so, how?
Trying to prevent the application from shutting down when clicked the X button, it still closing but the AIR process is running in the task manager. What wrong with the code?
I need to be able to call a method from a component located under the main application in Flex 4. Can anyone tell me please how to do this without using FlexGlobals please?[code]
I want to call a function in main flex app from the custom preloader code in actionscript before it dispatches complete event. Also i want to know how to call back to a function in preloader code from application
I wrote a singleton class to keep track of some variables across my application.
I am getting a syntax error that I can't figure out, I am sure that I am missing something simple but it's been one of those days. Anyone see something wrong with my code?
The error is 1061: Call to a possibly undefined method setResult through a reference with static type Class.
My function in my singleton class
public function setResult(resultNumber:int, value:int): void { switch(resultNumber) {
I'm tryng to make a public static method call another method, but Flash throws error 1180, sayng that the method called by the static method is undefined.
I need to get a javascript var in my Flash application. I like to be able to just set a variable in the javascript (client constraints) rather than define a function.
Can this be done? I am trying to use the ExternalInterface.call()
I am currently working on software for student attendance. I use the flex / flash and php to create the software but I faced a problem barcode scanner, can not connect to the application to call the data from the database when students scan the barcode printed on their student card.
I have a class. I can call the constructor (initialize the class), and the constructor can then call a function/method inside it's own class (so I know it works), but when I try to call the same function/method myself from the instance of the class I just initialized, I get an error.
I have a main application that contains a list, using a custom itemRenderer to display data.
I would like to be able to call a function, inside the itemRenderer, from the main application.
When running the app, we have a list with three persons, and a button. I want to call the function myItemRendererFunction() inside the itemRenderer, of the selected item in the list, all this, from the main app.
I am working with Flex 4 windowed application. I have a mx:HTML container with location attribute like [URL]. That abc.html has a html button and i want when that html button is clicked then a flex windowed application function should be called.
I've got a symbol on stage and a button. The button rotates the symbol CCW half a degree. Code: on(release){ mySymbol._rotation -= 0.5;} I wanna add an on (press and hold) action on button so that the symbol will be rotated continuously when the button is on hold.. I can't make this work for over a week now.
I have an issue with my eventListeners with the URLLoader, but this issue happens in IE, not in FF.
public function getUploadURL():void { var request:URLRequest = new URLRequest(); request.url = getPath();[code]....
The issue is that my getBaseURL gets executed automatically after I have executed the code at least once, but that is the case only in IE. What happens is I call my getUploadURL, I make sure the server sends an event that will result in an Event.COMPLETE, so the getBaseURL gets executed, and the listener is removed. If I call the getUploadURL method and put the wrong path, I do not get an Event.COMPLETE but some other event, and getBaseURL should not be executed.
That is the correct behavior in FireFox. In IE, it looks like the load() method does not actually call the server, it jumps directly to the getBaseURL() for the Event.COMPLETE. I checked the willTrigger() and hasEventListener() on _loader before assigning the new URLLoader, and it turns out the event has been well removed.
I simplified my code. To sum up quickly: in FireFox it works well, but in IE, the first call will work but the second call won't really call the .load() method; it seems it uses the previously stored result from the first call.
OK, from what I know actionscript in Flex runs asynchronously. I need the ability to run a method in a loop synchronously. Consider this code:
public class CustomerContainer extends VBox { public function CustomerContainer () {
[Code]....
This is not my exact situation as it is a bit more complicated to explain here. There is an abstract class and several custom view objects derived from it. Some of the views are dependent on others being completed first but I cannot seem to order them in the correct order. TIMERS are not an option. Probably not explaining this correctly.
