• On the QML and C++ integration (getting "undefined")

  This subject has been discussed often and I went through a lot of discussions, but I have not found a solution for my problem so far.

  What I want to do in my application:

  I have a container that displays an html page. No, I want a part of the html page dynamically filled a C++ function. Here is my Code:

  // HTMLCreator.hpp
  
  #ifndef HTMLCREATOR_HPP_
  #define HTMLCREATOR_HPP_
  
  #include 
  
  class HtmlCreator : public QObject{
  Q_OBJECT
  Q_PROPERTY(QString html READ html WRITE setHtml NOTIFY htmlChanged)
  public:
      HtmlCreator(QObject *parent = 0);
      ~HtmlCreator();
  
      Q_INVOKABLE QString html();
  
      Q_INVOKABLE void setHtml(QString html);
  
  signals:
      void htmlChanged(QString);
  
  private:
      QString m_html;
  };
  
  #endif /* HTMLCREATOR_HPP_ */
  

  // HtmlCreator.cpp#include "HtmlCreator.hpp"
  #include 
  
  QString HtmlCreator::html(){
      return m_html;
  }
  
  void HtmlCreator::setHtml(QString html){
      if(html != m_html) {
          m_html = html;
          emit htmlChanged(m_html);
      }
  }
  

  // applicationui.cppPage* ApplicationUI::doLoadPageDetails(){
  
      qmlRegisterType("myHtmlCreator", 1, 0, "HtmlCreator");
  
      QmlDocument *qml = QmlDocument::create("asset:///PageDetails/PageDetails.qml").parent(this);
      qml->setContextProperty("app", this);
  
      HtmlCreator *HtmlCreator = new HtmlCreator();
      qml->setContextProperty("HtmlCreator", HtmlCreator);
  
      Q_INVOKABLE QString HTMLString = "";
  
      HTMLString.append("
   
  A
   a 
  ");
      HTMLString.append("
   
  B
   b 
  ");
  
      MinutesData->setHtml(HTMLString);
  
      Page* newPage = qml->createRootObject();
  
      AbstractPane *root = qml->createRootObject();
  
      return newPage;
  }
  

  // PageDetails.qml
  
  import myHtmlCreator 1.0
  
  Page{[...]Container {
          layout: DockLayout {
          }
          horizontalAlignment: HorizontalAlignment.Center

          ScrollView {
              id: scrollView1
              scrollViewProperties {
                  scrollMode: ScrollMode.Vertical
              }
              layoutProperties: StackLayoutProperties {
                  spaceQuota: 1.0
              }
  
              scrollViewProperties.pinchToZoomEnabled: false
              scrollViewProperties.overScrollEffectMode: OverScrollEffectMode.None
  
              visible: true
              WebView {
                  id: webViewScrollable1
  //                url: "local:///assets/examples/test4.html"
  
                  settings.viewport: {
                      "initial-scale": 1.0
                  }
                  settings.zoomToFitEnabled: false
                  settings.textAutosizingEnabled: false
                  settings.defaultFontSizeFollowsSystemFontSize: true
                  settings.imageDownloadingEnabled: false
                  settings.binaryFontDownloadingEnabled: false
                  settings.cookiesEnabled: false
                  settings.javaScriptEnabled: false
                  settings.activeTextEnabled: false
  
                  html: " ...  lots of html code displayed correctly" +
                  HtmlCreator.html +
                  "" +
                  ""
              }
          }
  

  Now to the point where with HtmlCreator.html do I put her thong in the app I see "undefined" text

  What I'm doing wrong here?

  I found the solution!

  I missed to add my class as an attached object. So the container, the label or in my case WebView where I want to use the Q_Properties defined in my class, I have to add:

  attachedObjects: [
    HtmlCreator {
      id: htmlCreator
    }
  ]
  

  and then I can get the property

  htmlCreator.html
  

  But unfortunately
  the string I get is empty, so I'm still something missing here.

• Create a ListView in QML and then use it in C++

  Hi all, I've been struggling with QML and C++ integration for some time now.

  I'm at a point where I need a ListView in my application.

  Is it possible for me to create a ListView with its ListItemComponent and DataModel in QML and then use it in my code c ++?

  If so, a kind enough to provide a code sample on creating a QML object and then use it in c ++?

  Thank you very much

  Hey jayvd, there is a "CallaPizza" example call, the documentation links to the example is in the following link

  http://BlackBerry.github.IO/Cascades-samples/callapizza.html

  and you can download the example from github.

  In this example, they use a list written on QML the datamodel is managed on a C++ class, so you can use these same aproach to solve your problem. On the other hand, the propouse of Kanaksony solution might also work, you must have a reference to the object (qml) that contains the ListView, and then find the listView object, using the findChild method, once you have the reference to the list, you get access to all methods of properties.

  Cordially, Cristian.

• Indexing and the integrity constraint functionality difference

  Hello
  
  Sometimes I confuse me, how we can distinguish between indexing and the integrity of the features of constraint. Please let me know or if any available doc.
  
  
  Kind regards
  REDA

  I assume you mean unique vs unique index constraints?

  The sole (or Primary Key) constraints provide additional metadata that can be used by the optimizer.
  An index will be used to help the database to apply the constraint (it is created, or if there is it will be "captured" by coercion)

• Confused about autonomous OBIEE and OBIEE integrated this two Architecture

  Hello
  
  I'm confuse about autonomous OBIEE and OBIEE integrated this model two...
  
  Are these two situation based on the same application (and then after that install US based on the standalone OBIEE, BI applications it become integrated model)
  
  or are they two separate applications but integrated OBIEE this model can support BI applications?
  
  Kind regards
  
  Anne

  Hi Anne,.

  It's the difference,

  Autonomous OBIEE - has no any solution of BI preconstruitse, we build the solution based on our requirement with the suite of products.

  Integrated OBIEE or OBI Apps - are built on standalone. It provides this stand-alone version features all, moreover, it has predefined solutions.

• JavaScript JSON and ApEx integration

  In the community of ApEx, I see a lot of developers to extend their applications with JavaScript and JSON libraries. I would do the same thing to enjoy all the beautiful widgets, gadgets and gizmos that have been developed in the world of script.
  
  
  What is advice to better introduce the use of a script library?
  
  Team ApEx Oracle has an official thought on the extension of the ApEx in a script library?
  
  Y at - it a library which is recommended?
  
  Team ApEx does intend to extend their own library users don't need to use 3 parties?
  
  Have others using these issues experienced the 3rd-party libraries related to upgrades of the ApEx?
  
  
  I need a solution that is solid as a rock (no bugs) and bearable. The apps I support now have over a thousand users. Applications run on our company intranet. It would be undesirable to make calls outside our network http.
  
  Kind regards
  Todd

  Todd,

  We have certainly will continue work on the library, with the main objective on the realization of full namespace (to reduce the risk of collisions with different libraries functions) and the integration of jquery (making use of the features of the great library of basic such as chaining DOM selectors, improved, etc., but not of jquery UI).

  While it is currently possible to integrate with other libraries and many people have had great results with it, there are other plans for the future which should make life easier. To know custom item types, which allows developers to more easily code and reuse 3rd widgets to party in their applications.

  Another plan is what we call "Dynamic action", which will allow developers to set declaratively in the APEX for example activation, deactivation, display client side logic and hiding items. It is about making life easier for developers who do not want to dirty their hands with JavaScript, but still want to achieve such functionality in their applications.

  But I do not think that we could reach a point where "users have no need to use 3 parties. We are not all things to all people, different people have different requirements and tastes. For this reason, providing the best scalability (through custom item types) is the goal.

  We will also improve the documentation on the library, since 3.1, we had a few docs in chapter API user guide, but we will look to improve it with more detailed in future examples.

  Hope this helps,
  Anthony.

• Replacing the fan for w/15.4 "screen and GPU integrated T60

  Greetings,

  The combo fan/heater several months ago, I bought for my T60 was apparently the 41W6409 for a T60 with discreet gpu and cpu, but mine is an integrated model that uses the 41W6408.

  As I can't return it, I was just thinking to replace the old fan with that on the new heatsink. But I'm not sure that it will fit, being the only FRU I could find for the Fan/Heatsink combo.

  So, I was wondering if someone here who happened to know if these fans are the same.

  Thank you very much in advance.

  Steve, you can use the unobtrusive radiator on your integrated motherboard. In fact, the best option in my opinion is to go with a T61 heatsink that is designed to cool the much more powerful X 3100 graphics and uses the thermal paste rather than pads type blade of silicone used to cool graphic systems T60. Alternatively, you can replace these pads with thermal paste on the heatsink T60 but unity T61 is better in my opinion. I can't tell you if the fans are interchangeable, because there was more than one fan used on the T60 models intel, some were, and some were not. There was also a discreet couple different sinks of heat, but will be more than enough for the cooling of your integrated graphics. Platform which cools the discrete gpu will not be used so it isn't a problem and cooling chipset platform will suffice for the cooling of your integrated graphics.

• I have a new laptop and my integrated webcam does not work

  I need to get help fixing it. It's a brand new computer and the webcam does not work. When I try to access the program, it said that I need to plug a camera

  Hey amaury Muñoz.

  Welcome to Microsoft Answers Forum.

  1. can you please tell us the model number of your computer?

  2. is there a built in webcam or what is the model of your webcam?

  Can you please give us a little more detail on what is the specific error you get when you try to use the webcam?

  Check if you have the drivers installed for your webcam.

  As you say that it is a Dell computer, you will need to go on the http://support.dell.com website to download the driver of your webcam installed.

  Click on support and drivers.

  On the next page, it asks your name and your number.

  Select the exact model of your laptop.

• vWorkspace and Foglight integration not working

  Hello

  When I click on the diagnosis and the monitoring tab for any element (datacenter, virtual computer users) in vWorkspace I get the following error.

  See not found: system:vdidiagnostics_vmware_consoleintegration.viewCIVMWQuickView

  The Diagnostics tab and real monitoring itself works fine and opens my Foglight homepage without problem (I have installed on a separate virtual computer foglight)

  vWorkspace version is 8.0.306 and Foglight Foglight virtualization 7.1 trail verison.

  Any help would be appreciated.

  Thank you

  Hi André,.

  Foglight for. Virtual desktop (v5.6), which is now supplied with and integrated with vWorkspace and Foglight for v7.x virtualization (VMware) are similar but different products.

  If functionality (and URLs) supported in a single product do not work in the other. vWorkspace is hardcoded to work with Foglight for virtual desktops.

  If you have ITS current for vWorkspace, you are entitled to a copy free from Foglight for the virtual desktop, which takes in charge the two Hyper-V and VMware hypervisor infrastructure + followed by the components of farm vWorkspace.

• Complete ArrayDataModel QML and filling data in ListView

  Hello

  the filepicker, I get the file + the path to a file. Now I extracted the path and the name of the file to the string «selectedFile»

  Now, I want to add these two channels to an ArrayDataModel, which displays the data in a listview, the file name as the title and filepath as description.

  Here is my code:

  // Main.qml
  
  ListView {
    id: listview
  
    dataModel: ArrayDataModel {
      id: theDataModel
    }
  
    listItemComponents: [
      ListItemComponent {
  
        StandardListItem {
  
           title: ListItemData   <------------------ here I want to display the filename
           description: "filepath"   <-------------- and here I want to display the filepath
           imageSource: "asset:///images/icon.png"
  
  [...]
  
  onFileSelected: {  selectedFile = selectedFiles[0];  [...]    var filepath = *a string*    var filename = *a string*    theDataModel.append([filename, filepath]); <-------------- how can I add the two strings correctly to the datamodel?}
  

  What my code for the time when I take a file is that it adds two items to the list the first file name as title the second filepath as a title.

  How to manage to give the file name-path to the datamodel so that I can read both of them and put them in the view list?

  // Main.qml
  
  ListView {
    id: listview
  
    dataModel: ArrayDataModel {
      id: theDataModel
    }
  
    listItemComponents: [
      ListItemComponent {
  
        StandardListItem {
  
           title: ListItemData.name       <---------------------------------------------------|
           description: ListItemData.path  <-----------------------------------------------|
           imageSource: "asset:///images/icon.png"                                              |

      var filepath = *a string*                                                                              |
      var filename = *a string*                                                                            |
      theDataModel.append([filename, filepath]); <----------- how do I add the strings correctly so that I can us them in the list
  }
  

  Hello!

  For the arrayDataModel, I suggest you use this

  data var = {}
  'name': name of file,.
  'path': filepath
  }

  theDataModel.append (data);

  If you still have a problem, let me know!

• create component qml and then modify it

  I can create a component dynamically qml of my js, but I have to then check the values of the components.  I can't understand how to do this?  Can I give the created part somehow an id?

  You can give it rather objectName. This thread has some samples of use objectName:

  http://supportforums.BlackBerry.com/T5/Cascades-development/getElementById-in-QML/TD-p/2377935

  Or simply store the instance is created in a property and reference it through this property:

  property myVar variant

  ...

  myVar = xxx.createObject (parent)

  or

  myVar = JSFile.jsFuncCreatingAnObject)
