• Dynamically add controls QML since a QML function

  Hello!

  I would like to add a control available, under certain conditions. To do this, I want to write a function in QML which it will manage. But I don't know how to instantiate a label and add it. Container has the method add() but syntax that new Sun doesn't.

  Is it still possible?

  Thank you

  Hello!

  This can be done using ComponentDefinition. This page is an example:

• How to dynamically add any control (digital button, boolean) to control the line and selected column

  Hello

  How to add a control (digital button, boolean) dynamically in control instead of lines and columns selected. Please suggest the idea or no matter what example code you have please share with me...

  Thank you

  Vieu

  Essentially, that's what you're looking for:

  

  Please note that you have to account border sizes and the label of the control so that the code does not work right out of the box. You should also check for the height and width of column and if the position is valid at all before moving around the control.

• How to dynamically add data in a Spark list control

  Hi, I have a spark list in one of my custom components() control(id="Cclist") and a text input control. When a value is entered in the entry of the texts, I want to dynamically add the same in the list control. I tried to do the following:

  protected function Cc_selectHandler(event:CustomEvent):void
  

  {

   var cctext:DisplayObject = event.data as DisplayObject
   CcList.enabled = true;
   CcListButton.enabled = true;
  
   CcList.addChild(cctext);
  

  }

  But I get an error saying "addChild() is not available in this category.  "Instead, use addElement(), or change the skin. So I tried to use addElement, but apparently it is not available at all. No idea what im doing wrong?

  Add the text entered in the textinput to the dataProvider of the list in the appropriate format.

• Dynamically add custom headers in ListView

  I'm working with a ListView which is based on a api, that I have no control.

  I dynamically add some custom headers subject see the following as to what I am referring to (A, B)

  http://developer.BlackBerry.com/native/reference/Cascades/bb__cascades__listview.html

  How can I dynamically add these? For example, I want to add a conflict between the first element of the list and the second

  Section A

  Header

  Item B

  Point C

  Hi Philippe,.

  To do this, you must use a custom list item component.

  Heres how I could do that

   

  
  Moreover, in the custom "Header" just create a structure as follows:

  IF/ELSE ON A FLAG

  if(someflag == "header"){
       //use header style
  }else{
     // show normal list style
  }
  

  My Code

  ListView{
  dataModel: ArrayDataModel{
     id: myDataModel
  }
  
  listItemComponents: ListItemComponent
  {
      Container{
         layout: StackLayout{
            orientation: LayoutOrientation.TopToBottom
         }
         Label{
            text: ListItemData // complete data string
         }
         Label{
            text: ListItemData.split("~")[0]
          }
          Label{
            text: ListItemData.split("~")[1]
          }
         Label{
            text: ListItemData.split("~")[2]
          }
      }//end Container
  }//end ListItemComponent
  
  onCreationCompleted: {
     //The data inside append is one item.
  
     //let's append a bunch of data
     for(var i=0;i<30;i++){
         //append 30 list items
         myDataModel.append("Header~Some data whatever~Status");
     }
  }
  }
  

  • In my example I am adding data to the model.

  ListItemData - the full string

  ListItemData.split("~") [0] - first part etc.

  • I shared parts of the data with a single symbol. In my case the «~»
  • To get the data I want to that I just throw a ListItemData.split("~"). It breaks the string into 3 parts.
  • I will be able to access somewhere I want using the notation ListItemData.split("~") [index]
  • You can include paths to images, or whatever the text you

• How to dynamically add a plot to a graph of mixed signals

  I have a graph of mixed signals where I'm plotting a signal from a time axis. I'm trying to dynamically add a second plot to this graph against the same time axis (with a different scale of Y), but when I built a 2D array and try to connect in the graph (using a local variable) I get an error of size mismatch. I know for sure I did in the past (cable tables with different sizes for a same MSG) with no problems but, today, for some reason any I can't solve this problem.

  Am I missing something?

  Yes, you're probably writing a table 1 d somewhere that is causing to accept only 1 d. To address your problem above, just put a table node build in whenever you have a 1 d table and it will be just a 2D array with a single line of data.

  To add a field to your current locations, your screenshot above should work once the plot knows that he has to accept the 2D tables.

  Reading from a local variable, change something and then write about it once again can lead to a lot of issues down the line. Race conditions are a pain in the butt, so get rid of that sort of thing is good to do from the start. I didn't know the rest of your code, so I don't know how you treat it, but just keep in mind that you add to your software.

• REALLY disturbing dynamic sound control

  I bought a HP ENVY 17 Notebook PC in September 2012 and I really like it! Wonderful machine, releasing my creativity... Well, not really. I listen to music when working, but there is this terrible dynamic volume control. It cut spikes and stimulates the troughs, which I'm not interested. Or at least try that. Indeed, there is a delay to that effect, so that the adjustments are happening a little too late. In addition, the paler parts are completely reset to zero, probably because white noise dominates the picture. Maybe it's a good idea for children playing games and watching action movies, but he certainly isn't a good idea when you are listening to classical music. What can we do about it? I haven't used my CD equipment for ten years, I've eventually there again? Turning off beatsaudio does not help. The following patch help for HP ENVY? FTP://FTP.HP.com/pub/SoftPaq/sp57501-58000/sp57966.html , please help me! I can't go on like this any more!

  If you have not already, I download and install this hotfix. It should help to solve the problems you are having.

• How to dynamically add an Option in the drop-down list?

  I have this code:

  {Drop-down list

  ID: list

  Title: 'list '.

  onCreationCompleted: {}

  opion var = new Option();

  opion. Text = "Hello";
  opion. Value = 4;

  List.Add (opion);

  }

  }

  After the launch of the application, the list is empty.

  Why my code does not work?

  It is easy to dynamically add options

  first add this to your attachedObjects:

  ComponentDefinition {
              id: optionDefinition
              Option {
              }
          }
  

  then do something like this

  var newOption = optionDefinition.createObject()
              newOption.text = ...
              newOption.value = ...
              newOption.description = ...
              newOption.selected = ....
              yourDropDown.add(newOption)
  

• Dynamically add tabs QML from C++

  Hello world

  I have a simple TabbedPane defined in QML.  I am trying to reference the TabbedPane via C++ to dynamically add tabs.  Is this possible?  With my current setup, the application starts and crashes then with:

  Process 22253787 (MyTabsApplication) terminated SIGSEGV code=1 fltno=11 ip=79310524(/base/usr/lib/libbbcascades.so.1@_ZN2bb8cascades10TabbedPane6removeEPNS0_3TabE+0xf3) mapaddr=00110524. ref=00000010
  

  Here is the code:

  TabbedPane {
      id: mytabs
      objectName: "mytabs"
  
      Tab {
          title: "Tab 1"
          FirstPageView {}
      }
      showTabsOnActionBar: false
  }
  

  C++ :

  ApplicationUI::ApplicationUI(bb::cascades::Application *app) :
          QObject(app) {
  
      QmlDocument *qml = QmlDocument::create("asset:///main.qml").parent(this);

      Tab* tab = Tab::create()
                   .title("tab2")
                   .description("This is only shown in the side bar");
      tab->setContent(page);
      tabbedPane->add(tab);
  
      app->setScene(root);

  Thank you!

  Try to declare your root as:

  TabbedPane *tabbedPane =  qml->createRootObject();
  

  As TabbedPane is a class of AbstractPane

• How we can dynamically add or remove action from the popup menu in qml item

  Hi all

  I want to just dynamically add or remove action from the actionset item in the contextual menu especially in qml.

  Thanks in advance.

  Kind regards

  Ankur

  You can do so by joining the actionitem as attachedObjects. Once the page is complete (signal onCreationCompleted), you can add it to the page using addAction()

  To remove, you simply delete the page using removeAction()

• Dynamic add to cart

  Hey everybody, just try to see if there's a way dynamically add something to the cart. I see the html code for how works the add to Cart button, but it looks like it uses the ID 'product' to add the product itself. However, I am not able to see how I can retrieve the id of the product if all I have is the 'Product Code' (from {tag_productcode}). These two values are different for non insiders.

  I know that if I work a little longer on that I could just get some ajax to visit the real great product page manually and find add to Cart button and enter the ID of the product in this way, this seems excessive.

  If anyone has any ideas, I would be very grateful.

  With the add to Cart then that.

  I don't know why people do not use the documentation - all that it:

  The developer reference

  {{id}}	{tag_productid}	System displays product ID.
  {{catalogId}}	{tag_catalogueid}

  These two you will need dynamic, but make sure you also get the other correct settings.

• Dynamically add UIComponent without refreshing entire page (JDEV 11.1.1.3)

  Hi all
  I have this problem.
  
  I need to dynamically add an element within a page without refreshing entire page jspx.
  
  For example, look at this page:
  
  
  Titus: _
  Name: _______
  Job: _ (+ add more jobs)
  
  When I click on (+ add more jobs), I add a new RichInputText:
  
  private RichPanelBox pb1;
  
  public String cb1_action2() {}
  RichInputText rc = new RichInputText();
  rc.setId (...);
  [....]
  This.PB1.GetChildren (). Add (RC);
  Returns a null value.
  }
  
  The field is displayed properly on the page, but the system do a full refresh and lose your position on the page.
  
  Obviously becomes inconvenient for the user to have to scroll the page up to a certain point where it was before.
  Is it possible to avoid this problem and to add the field without a complete refresh of the page?
  
  Thank you
  Cristian

  Try with PartialSubmit for the button and use PPR as follows:

  JSPX Code:

  
  
  
  
  partialSubmit = 'true '.
  actionListener = "#{SamplePageBean.onAddJobs}" / >
  
  
  
  
  

  Bean code:

  public class SamplePageBean {}
  private RichPanelBox panelBox;

  public SamplePageBean() {}
  }

  {} public void onAddJobs (ActionEvent actionEvent)
  RichInputText richInputText = new RichInputText();
  richInputText.setId ("Id1");
  richInputText.setLabel ("Job Title");
  this.panelBox.getChildren () .add (richInputText);
  AdfFacesContext.getCurrentInstance () .addPartialTarget (this.panelBox);
  }

  {} public void setPanelBox (RichPanelBox panelBox)
  this.panelBox = panelBox;
  }

  public RichPanelBox getPanelBox() {}
  After a return;
  }
  }

  Thank you
