• List component: problem filling with actionscript

  Using code to add or remove items to list works very well with files with little code. Add any other code (not related), it is not populate the list correctly.
  
  Makes me maaaaaaad.
  
  I tried various export on the first frame / load classes in the framework: options.
  
  
  
  

  Thanks, GWD.

  I did a bit of code remove, but you convinced me to do a lot more in detail and I get at least a populated list now. The 'offending' code seems to be defining the functions of prototype for arrays (if attached) that appear to be independent. (Don't think that there is something wrong with this code in itself). Perhaps these change the array class which interfere with the loading of the class list or something. Oddly enough, I still have a defined string prototype function that does not seem to cause problems.

  Nasty little problem, because it arises only in the update when I thought I could got the lists already works.

  Thank you

• Access a drop-down list component created in fom runtime C++

  Hello everyone.

  I included a file "Settings.qml" as a ComponentDefinition in my file "main.qml" as follows:

  *******************************
  main.qml
  *******************************
  
  Page {
      id: page
  
      //App menu
      Menu.definition: MenuDefinition {
          settingsAction: SettingsActionItem {
              title: "Settings"
              imageSource: "asset:///icons/ic_settings.png"
              onTriggered: {
                  var settings = settingsSheet.createObject(_cam);
                  settings.open();
              }
          }
      }
  
      //Main container
      Container {        Camera {            id: cameraQML            objectName: "cameraQML"        }    }
  
      //Attached objects
      attachedObjects: [
          //*****this is the component definition****
          ComponentDefinition {
              id: settingsSheet
              source: "Settings.qml"
          }
      ]
  }
  

  Then, in the "Settings.qml" file, I have something like that.

  On the crack of onCreationCompleted I call you access of wich C++ function to the cameraQML component and gets the available resolution values and add them to the drop down list component.

  ***********************Settings.qml***********************
  
  Sheet {
      id: settingsSheet
      objectName: "settingsSheet"
      peekEnabled: true
      content: Page {        Container {            DropDown {
                  title: "Capture Resolution"
                  objectName: "resolution"
  
                  options: [
                      Option {
                          text: "16:9"
                          value: 16/9
                      }
                  ]
  
                  onCreationCompleted: {
                      _cam.loadResolutionValues();
                  }
  
                  onSelectedValueChanged: {
                      //_cam.selectResolution(selectedValue);
                  }
              }
          }    }}
  

  The PROBLEM comes when I try to access the menu item drop down because, even if I get error when you call the function findChild(), I do when I try to add Options by calling the add() function:

  ******************applicationui.cpp******************
  
  AbstractPane* root;Camera* cameraQML;DropDown* resolutionsDD;
  
  void AppliactionUI::ApplicationUI() {    //code...    QmlDocument *qml = QmlDocument::create("asset:///main.qml").parent(this);    qml->setContextProperty("_cam", this);    root = qml->createRootObject();    cameraQML = root->findChild("camera");    //code...}void ApplicationUI::loadResolutionValues() {
      QVariantList reslist = camaraQML->supportedCaptureResolutions(CameraMode::Photo);
                  //**I don't get error by calling this function
          resolutionsDD = root->findChild("resolution");
  
          //**The app do crashes when calling any of these three functions
      //resolutionsDD->setTitle("Choose an option");        //resolutionsDD->removeAll();
      //resolutionsDD->remove(resolutionsDD->at(0));    for (int i = 0; i < reslist.count(); i++) {
          qDebug()<<"QVatiant value:"<add(Option::create().text(res.width()+"x"+res.height()).value(reslist[i]));
      }
  }
  

  I thought it was a problem with the type of value, I was put in the service. value() when you create an option, but then I realized that, while trying to change the title from the drop-down list, or delete i ' ts options that the application crashed also.

  This makes me think that the problem is that I'm not a correct reference for component drop-down menu QML due to the fact that this drop-down list does not exist when the application starts and is created until the user opens the Settings.qml file. Also, I think that this is a problem with all that stuff parent and child, but of course, it's just a feeling.

  I'd really appreciate your help on this type of problem. I'm not experienced enough to know what is the right way to get a reference of work to the drop down list component in question in a situation like this

  Thank you very much in advance!

  P.D. I'm sorry, I know that my English is not very good. Hope you do not misunderstand

  Hello
  Very probably findChild returns NULL and a NULL pointer dereference causes the crash. I remember there was problems with findChild during the use of the leaves.

  Try from the drop-down list directly to the function as an argument:

  (1) in applicationui.cpp:

  After:
  QmlDocument *qml = QmlDocument::create("asset:///main.qml").parent(this);
  
  Add:
      // This is needed for passing DropDown in function parameters from QML to C++
      qmlRegisterType("bb.cascades", 1, 0, "DropDown");
  

  (2) modify the function declaration for:

  Q_INVOKABLE void loadResolutionValues(bb::cascades::DropDown *dropDown);
  

  (3) in QML:

  DropDown {
    id: dropDown
    ...
    onCreationCompleted: {
       _cam.loadResolutionValues(dropDown)
  
       // _cam.loadResolutionValues(this) // maybe this will also work, but I haven't checked
  
    }
  }
  

• Horizontal scrolling in the list component

  Hello

  I use a list component, which is filled from a textbox control.  I set the horizontal scroll policy to automotive and also we however scrolling does not appear (in the case of auto) or does not move (in the case of it).  Is there a setting I need to change to make the scrolling work normally?

  Thank you

  you need not use invalidate().  use:

  lc.horizontalScrollPolicy = ScrollPolicy.ON

  lc.maxHorizontalScrollPosition = 200;   Use an appropriate number

• SelectedItems value for List component

  I was able to put 1 items in a list, but not many. I've searched and searched and I can't find out how to do this.

  This code is taken to the right of the section of help for the List component documents in the List.selectedIndices section.  Add an instance to the stage and name it my_list and the code will do the rest.  In the code, a table is used to assign multiple selections, since it is implied the selectedIndices, an array property... my_list.selectedIndices = [0, 2];

  my_list.multipleSelection = true;

  my_list. AddItem ({data: "flash animation", label: "Flash"});
  my_list. AddItem ({data: "dreamweaver", label: "Dreamweaver"});
  my_list. AddItem ({data: "coldfusion", label:"ColdFusion"}); "})

  my_list.SelectedIndices = [0, 2];

  var numSelected:Number = my_list.selectedIndices.length;
  for (var i: Number = 0; i< numselected;="" i++)="">
  trace ("selectedIndices [" + i + "] =" + my_list.getItemAt(my_list.selectedIndices[i]).label);
  }

• ActionScript for List component

  I'm developing a glossary for a course of training, and I have my list component set up with all my terms.  Now, I need to program when the user clicks on a term, the definition appears.  I thought there was a way to do it, but my book does not in this detail.

  can anyone help?  Here's actionscripting I found online, but he says he can not work with Actionscript 3.

  Import fl.controls.List;
  Import fl.controls.TextArea;
  import flash.events.Event;
  Import fl.data.DataProvider;
  
  var glossary: List = new List();
  var Definition_Text:TextArea = new TextArea();
  var items: Array =]
  {label: "AbbrDial", data: "Dial allows an index number speed dial."},
  {label: "Response", data: "Allows you to answer a call."},
  {label: "Back", data: "Lets go back to the previous Help topic."},
  {label: "Barge", data: "Allows you to add yourself to a call on a party line."},
  {label: "Recall", data: "Allows you to be notified when a busy extension will be available."},
  ];
  Glossary.dataProvider = new DataProvider (items);
  
  addChild (Glossary);
  addChild (Definition_Text);
  
  Glossary.Move (150,150);
  Definition_Text.move (150, 260);
  
  Glossary.addEventListener (Event.CHANGE, changeHandler);
  
  function changeHandler(event:Event):void {}
  Definition_Text.text = event.target.selectedItem.data;
  };

  You don't need to build components, just them in the library.  The code does all the work for you.

  Open a new file, copy the code you posted to frame 1 of the scenario of this file... go into the component library and drag an instance of the List component to the stage and then delete it. go in the asset library, drag an instance of the TextArea component to the stage and then delete it..., run the file.

• Spark list component Icon property?

  in Flex 3.x the VBox property was property of the icon that you can use to set the images in the elements of the list as well as the label property. How can I get the same thing in a Flex 4 spark list component?

  I would like something like 'iconField' property set to the list item, so that my itemrenderer can be generic and not worry for a specific type of object is passed in.

  Thank you!

  I have the subclass would list, add an iconField property and change the default

  renderer a converter custom will check data [iconField] for a

  icon and display it.

• List component

  Hi guys,.

  Thanks in advance for considering help me lol... anyway, I was wondering how to fill a list box item located inside a mc separated in my swf with a table... the table is from a response from a Web service call. I'm not currently on the computer with my source code available allows, so just use the following...

  listData [i] = the table I want to fill the list box with... (listdata1, listdata2, listdata3, listdata4, etc etc)

  movieclip1 = MC in my fla that contains the list box component

  MYLIST = the list item

  ... simply not all this that familiar with the format of actionscript code when you work with objects... using CS3 and as2 btw.

  To fill the List component, use you the addItem() method.  How you specify the day depends on what each element of the array holds, but the basic approach if each element of the array is a unique piece of data would be...

  for (i = 0; i

  movieclip1.myList.AddItem (listdata [i]);

• Strange VideoDisplay component problem

  Hello

  I have an interesting question with the VideoDisplay component. I have a list of .flv files that appear in a List component. When the user clicks on one of the file names, click contains the path to the file and puts it into a bindable variable called "contentFile".

  I then use the source property of the VideoDisplay to define what video to begin playing.

  My code is simple and it works. Here it is:

  < mx:VideoDisplay x = "0" y = "239" width = "320" height = "240"

  ID = "vidDisplay".

  source = "{contentFile}" / >

  Here's the strange thing. When to use the following code:

  "source ="{contentFile}"

  my video takes several seconds to set buffer in advance before it starts to play (depending on the size of the source .flv file). Then when it starts to play, half the time that the video is very choppy, half the time it plays OK.

  However, when I set the source using an exact path for a video such as:

  source="/myVideos/myCoolVideo.flv".

  the video immediately loads almost instantly and play always super smooth. I tested this out on Mac OS x, FireFox, Safari, and WinXP in FireFox and IE. The same answer is repeatable. The same exact video chosen via the variable method bindable takes a while to load and playback can be summary.

  What can possibly be the difference between these two methods?

  Let me know if you need more information.

  Thank you

• DRM component problem, can't update Windows Media Player security

  I try to use my OverDrive and I have this same problem of 'a problem has occurred in the DRM component. Contact microsoft support"with the button unclickable on the link I see that many others have had. I looked at previous answers for them and I have renamed my DRM folder to DRMbackup, changed my proxy on Windows media player settings, troubleshooted the patch use windows media he asked (including reinstall them WMP), cleared my cookies in IE and firefox, and the update button is unclickable. I've also been running IE as an administrator. This is ridiculous. I just click the button to update my DRM and get on with it (I'm not worried about the previously protected songs) what else can I try not to mention that from another computer? I've been troubleshooting for more than 3 hours!

  I had the same frustration. Finally resolved with instructions to: http://support.microsoft.com/kb/976590.

  I hope this helps.

• QML: To access variables defined outside of a list item to in a list component

  Consider the following QML:

  import bb.cascades 1.0

  
  

  {Page}
  content: {container
    {Label
    ID: topLabel
        text: «One»
        textStyle.size: 100.0
        textStyle.color: Color.Blue
    }

      Button {}
        text: 'change two.
        onClicked: {}
        topLabel.text = "Two"
      }
      }

  
  

      {To ListView
        objectName: "testList".

        listItemComponents:]
        {ListItemComponent}
          type:
          Button {}
            text: "change to three.
            onClicked: {}
              topLabel.text = "Three"
            }
          }
        }
      ]

  maxHeight: 300.0
  }
  }
  }

  The pages defines three controls: a label, a button, and a listview. In turn, each listview item also contains a button.

  By clicking on the button below the label successfully changes the text of the label through this code:

  onClicked: {}
  topLabel.text = "Two"
  }

  However, the execution of a similar code from the button in the listview control fails with this error:

  Test.QML:28: ReferenceError: can't find variable: topLabel

  Apparently, the variables defined outside the listview are not directly visible since in listview items.

  Y at - it available to access syntax?

  Thank you

  Jamie

  OK, we have identified a work around that should solve your problem, as suspected, she was reported linked so a redefinition is necessary.

  At the high level of the Page of the page, add the following line so that the label is accessible.

  {Page}
  ID: topPage
      
  onCreationCompleted: {Qt.topLabel = topLabel ;}
          
  Then, in the button definition, you can reference the Qt.topLabel in the list.

  listItemComponents:]
  {ListItemComponent}
  type: 'point '.
  Button {}
  text: "change to three.
  onClicked: {}
  Qt.topLabel.text = "Three";
  }
  }
  }
  ]

  Hope that solves your problem. Of course, it worked on my system.

• Rendering html with the webview component problem

  Hello

  I have a big problem to render this page html with the webview component:

  The problem comes from the "perspective" in - webkit-transform. No it's ok. But with this one, the result is different from a standard browser like chrome or safari.
  

  
  

  Could you help me?

  
  

  Thank you.

  attributes css - webkit are not supported by JavaFX WebView.

  attributes css - webkit are not standard (for example, they are unlikely to work either in IE or Firefox).

  CSS transformations are currently experimental technology, usage that is not normalized in user agents.

  You can request this experimental technology by creating a feature request.

  If support for css transforms has been added to the Web format, he would use standardized for attributes and not names - webkit prefix names.
