delegate in as3

• AS3 - function passed as an argument brought bad when it is called

  Hi all

  I'm new to flex. I tried this: http://seancode.blogspot.com/2008/07/flex-injection-passing-function-to.html

  This message essentially has a MyBox component that gets a function as an argument and calls the function on a button click.

  There another component main , which has defined a function func and MyBox as a child and gives the MyBox service.

  The problem is: func accesses the properties of the hand. So when he gets called it is supposed to work at hand , but in my application is running in the scope of MyBox and give a reference to property not found error.

  I read that in AS2, mx.utils.Delegate was used to specify the scope in which a function must run. This has been used to define event listeners. And AS3 is supposed to do this automatically - magic closures/methods. I had no problem setting of event listeners, and they run in the correct scope...

  Please tell me where I'm wrong... There is no delegate to work around this problem now. And I couldn't find anyone else facing this problem in AS3.

  Thanks in advance...

  Hello

  The problem is that you use a function inline instead of a bound method. In this case, when you use an inline function, this function will be the scope of the caller (following the example of the appellant will be to the MyBox component) and not to the scope of the creator (hand). You can find more information about the scopes of service here: http://livedocs.adobe.com/flex/3/html/help.html?content=03_Language_and_Syntax_21.html

  If you do not need the Bindable part, you can work around the problem by using a method/function related:

  (using the same example you provided)

  private function backToViewZero():void {
       viewStack.selectedChild = viewZero
  }
  

  Another way (without throwing the binding mechanism) is to use the method of the function call and specify the thisArg as being the parent (main).

• Doesnot Delegate.Create works inside the IDE... why?

  Someone can help me understand why delegate.create doesnot work inside of the flash ide (but works only within a class)

  for example: if I try to run it on the flash IDE, then it shows me 'undefined '. Why this is happening within the ide?

  createButtons();

  
  function createButtons (): Void {}
  for (var i: Number = 0; i < 5; i ++) {}
  var tmp:MovieClip = _mc.createEmptyMovieClip ('b_' + i, i);
  tmp = attachMovie ("bid", "quote" I, I + 100);
  tmp._x = 40 * i;
  tmp.onRelease = Delegate.create (this, hurry, I);
  }
  }

  
  function pressed(n:Number):Void {}
  trace ("_onRelease:" + n)
  }

  It's AS2 code, this is the forum of AS3.  Try the repost in the AS2 forum.

• What is AS2 for Event.REMOVED_FROM_STAGE (AS3)?

  Hello

  I'm used to AS3 and translate in AS2.  I want to check if something has been removed from the scene.  In AS3, I used this:

  obj.addEventListener (Event.REMOVED_FROM_STAGE, objRemovedFromStageHandler);

  How can I do this in AS2?

  I tried to use the delegate class to implement an onEnterFrame event I can delete then.  I have this use of the events of the button clicks etc but not onEnterFrame.  Well, I can make it work, but how do I set up so that I can remove a specific onEnterFrame, that I need to use several onEnterFrame throughout the alphabet?

  Any suggestions very welcome.

  Thank you very much

  Mike

  in as2, you can simply check whether the object exists:

  If (obj)

  but no event is dispatched.

  If so, it's either on stage or behind the scenes which you can check if necessary.

• El Capitan Server - calendar, no delegates in iCal show

  It is a new installation of OS X server. I created users and turned on the shared calendar.

  I connect to Apple "iCal" on an El Capitan Mac client. I go to Prefs > accounts > delegation and click on edit to add delegates. It can find any users name I created.

  What Miss me?

  Thank you

  I think that it is a problem of the customer. The calendar and reminders app in OS X 10.11 appear to OS X in delegated server problems. I was able to assign delegates by accessing the calendar through the web server (https://server.url/webcal).

• Life of delegate class semaphore

  Hi all

  With the help of LV2015 I have known a few frustrating behavior involving semaphore references dying in a delegate class that contains references to semaphore in the class data. I know that if the VI who created semaphores leaves memory, semaphore references will leave with her. However, I'm not sure what means "leaving the memory" when it comes to LVOOP or involuntary strange behavior on display there.
  In the example attached, I call two classes directly from top level. A class creates a semaphore reference and stores it in the class data. Lets call it owner of semaphore. The other class stores the first class in the class data after the semaphore has been initialized. Allows to call the classroom teacher. When I try to get the status of the semaphore by using the holder of the class I get error 1, invalid refnum. However, if I get the status of the semaphore using the original holder Semaphore class I don't get any error, even though the holder of the class said that the refnum of the semaphore is not valid. Is there a way to store a delegate class that has already been initialized without losing the references?

  Thank you

  jppb

  The problem is in your method of "write holder of semaphore. You will notice that the beam is not actually updating the output of class (try block diagram cleanup to see). It is a common trap.

• AS3 Library in BB10

  Hi, I plan to develop air (AS3) on BB10.

  My question is:

  1. What's the difference / limitation in the BB10 AIR and AIR Office? Any obvious restriction of BB10 AIR?

  2 is the library as flash.text.TextFieldcan be used?

  Thank you! Hope someone could help me with that.

  Hi, thanks for the response.

  This means that Starling is also supported?

• Send the signal to a delegate

  Hello

  I have a small question I would like to address. Basically, I have a TabbedPane in my main opinion, each of my tabs are delegated qml files. And I would like to connect the signal "onTriggered" tab to an action of a ListView that is declared in the delegate refreshment. But I don't know how to talk with the content of the delegate outside of it. Is it possible to do?

  Just to make it easier to understand, here's some code. My main page is like this:

  TabbedPane {
      id: mainTab
      showTabsOnActionBar: true
  
      Tab {
          id: tabFav
          title: qsTr("Favorite") + Retranslate.onLocaleOrLanguageChanged
  
          imageSource: "asset:///images/icon_favorites.png"
  
          delegateActivationPolicy: TabDelegateActivationPolicy.ActivateImmediately
  
          onTriggered: {
  
          }
  
          delegate: Delegate {
              id: favorite
              source: "Favorite.qml"
          }
      } //End of favorite tab
  }
  

  And Favorite.qml like this:

  NavigationPane {
      id: nav
  
      Page {
      Container {
              layout: DockLayout { }
  
              ListView {
                  id: listFav
              }
  
              function refresh() {
                 // do some stuff
              }
       }
  }
  

  Is there a way to connect the signal onTriggered from the tab to the refresh() function in the Favorite.qml?

  Thank you very much

  Hello

  Thank you for you answer. This is exactly what I wanted; the idea was: If you have the already active tab and hit again on the tab, it refreshes the display.

  So if someone struck twice on the button, the second time "onActiveTabChanged" is not raised because it is already active, but I want to take this event to refresh the view.

  But I found a solution:

  TabbedPane {
      property variant favController
      property variant pmController
  
      Tab { //Favorite tab
          id: tabFav
          property bool isInitDone: false
          title: qsTr("Favorite") + Retranslate.onLocaleOrLanguageChanged
  
          imageSource: "asset:///images/icon_favorites.png"
  
          delegateActivationPolicy: TabDelegateActivationPolicy.ActivateImmediately
  
          onTriggered: {
              if(isInitDone)
                  favController.getFavorite();
          }
  
          delegate: Delegate {
              id: favorite
              source: "Favorite.qml"
          }
      } //End of favorite tab
  
      Tab {
          id: tabPM
          property bool isInitDone: false
          title: qsTr("Message") + Retranslate.onLocaleOrLanguageChanged
          ActionBar.placement: ActionBarPlacement.OnBar
          imageSource: "asset:///images/icon_mp.png"
          delegateActivationPolicy: TabDelegateActivationPolicy.Default
  
          delegate: Delegate {
              source: "PrivateMessage.qml"
          }
  
          onTriggered: {
              if(isInitDone)
                  pmController.getMessages();
          }
  
      } 
  
      onCreationCompleted: {
          tabFav.isInitDone = true;
      }
  
      onActiveTabChanged: {
  
          if(activeTab == tabFav) {
              tabFav.isInitDone = true;
              tabPM.isInitDone = false;
          }
  
          if(activeTab == tabMP) {
              tabFav.isInitDone = false;
              tabPM.isInitDone = true;
          }
      }
  }
  

  NavigationPane {
  
      Page {
  
          Container {
              layout: DockLayout { }
  
                  ListView {
                    id: listFav
                  }
  
               attachedObjects: [
                   ListFavoriteController {
                       id: listFavoriteController
  
                   }
                  ]
          }
  
          onCreationCompleted: {
                  listFavoriteController.setListView(listFav);                listFavoriteController.loadView();
  
  // ---------------------------------- NEW --------------------------
                  favController = listFavoriteController;// -----------------------------------------------------------------
              }
      }
  }
  

  So basically, when the Favorite.qml page is created, I provide a pointer to the controller of the TabbedPane. And then, it can process in the 'onTriggered '. I had to manage tab and change to avoid refreshing the page twice, but it seems to do the job.

• AS3 / AIR - BB10 problem: TextInput, counting and Format

  Hello world

  I hope that I have forget something small and appreciate any help sincerely.

  Short version of the problem:

  When I add a skin to a TextInput object, assign a skin, I can't change the color of text.  If I remove the skin, it works.  And the skin seems to work correctly.  Seems the class of skin does not contain not controls font forground color.

  How can I change the background color and a TextInput for BB10 forground using the AS3 BB10 Gold SDK?

  Long version:

  Help: import a qnx.fuse.ui.text.TextInput;

  I have an application with 12 different themes.  In the application, I wish the TextInput box to inherit the theme settings.

  Normally, I use the following to define a format.  And it works on its own.

  var a: TextInput = newTextInput;

  var b:TextFormat = newTextFormat;

  b.Color = 0xFF0000;

  a.format = b;

  However, in order to change the color of the background for the TextInput, I needed to create a custom class.

  public class myTextInputSkin extends UISkin

  That's a lot of vars:

  protected var upSkin Pright;

  protected var focusSkinPright;

  protected var downSkinPright;

  protected var disabledSkinPright;

  public var borderSize:uint = 2;

  Who also works on its own to replace the background.  However, once I attribute the UISkin to the TextInput, it prevents the format never applied to the TextInput.

  var a: TextInput = newTextInput;

  var b:TextFormat = newTextFormat;

  a.setSkin (myTextInputSkin);

  b.Color = 0xFF0000;

  a.format = b;

  No matter how I trace out, it seems that is applied to the object and the skin is applied to the object.  Seek to deepen the TextInput function, it has a buried in TextField.  I can confirm that setting format reached the TextField object buried inside the TextInput, which means that the format should be really change.  I tried to manually trigger the event of colors of fonts to update inside the text input?

  Anyway,.

  Now I'm in a bit of a loss, and I feel I'm missing something simple and stupid.  Someone at - it ideas?

  Ed.

  Thank you!

  For now, I have "unskinned" these elements.  Once it gets patched, I'll reconsider.

• FlexUnit with AS3 AIR does not work?

  Recently, I tried to take a shot at TDD (Test Driven Development), as I'm sure many of you know.  To do this I tried to use FlexUnit 4 of in Flash Builder 4.

  If I create a project as follows:

  1. New--> Flex project
  2. Next, Next
  3. (The main Application file) Replace .mxml, .as
  4. Finishing

  Then when I try to use FlexUnit in the ordinary way, it fails to generates an adequate FlexUnitApplication.mxml.  The content of this file is:

  
  
  package_declaration
  {
  class_declaration
  {
  class_body
  }
  }
  

  Therefore, there is a compile error that I can not move:

  Content is not allowed in prolog.
  

  However:

  If I followed the same process as above, without changing the .mxml to .as tests run correctly.

  Things, I tried to work around the error:
  

  • FlexUnit to 4.1 update
  • Pressing refresh in the FlexUnitsResults window
  • Creating a project with .mxml and thereafter remove this mxml and its replacement with an actionscript class
  • Bump on my desk.

  None of them have worked.

  Did anyone here successfully FlexUnit FlashBuilder 4 for an AS3 AIR project all?  If not, can anyone suggest another Test package?

  Thank you

  ~ Nick.

  I found a solution at least provisional.  I restarted FlashBuilder and despite the error marked under issues here and it worked.

  I think that restart Flashbuilder maybe erases a previously stored properly compiled build.  (Maybe Clean could also do this?).  in any case, at the time of compilation, the mxml file was generated correctly and all is well.

• AS3 animation slow/choppy

  Hi all

  I'm having a bit of a problem with the Simulator and hoped one of you knows how to improve things, if that's possible.

  My problem is when you use the ENTER_FRAME or TIMER events for animation. Animation on the Simulator is very slow/choppy/incompatible. I guess that this is related to VMWare and not the OS simulator.

  Has anyone experience this problem? If so, have you been able to solve it? Otherwise, any other suggestions?

  Thank you!

  I'm also running at 30 fps.

  The filters are bad for performance. Try to limit their better use that you can. Often, you can achieve the same effect by creating the desired effect in an external image editor (for example, Photoshop), then import the image.

  Turning with a filter is probably worse because the use of filters set cacheAsBitmap to true. Objects rotating (or scale) with cacheAsBitmap uses CPU more. If you simply have the first loss of performance, using filters and then you take another hit when rotating on top of that. If you do a lot of this can be pretty bad.

  http://help.Adobe.com/en_US/AS3/mobile/WS4bebcd66a74275c36c11f3d612431904db9-7ffc.html

  However, that may not always be the source full of all your performance issues. Try to remove them entirely, and see if everything clears up and you will know if they are the only issue or not.
