The data in the list scrolling

• Scroll the list of QNX

  Hello

  I study the QNX components to check/improve the performance of my Spark App (this is for background).

  So I try to use the list scrollToIndex method in order to view a new item added to the list:

  myList.scrollToIndex (newIndex);

  But it does not for the moment... I have no animation, and the new item is not in sight.

  (I check the using element status: myList.getIsCellVisibleAtIndex (newIndex))

  Does he know how to use this method in order to have an animation of the list smotth?

  Finally work!

  Short story: I was preparing a BUG report, my sample did not work as expected and suddenly after set/reset some settings, the list scrolls smoothly like a charm!

  So I do not know what is / was the problem, but I could apply a workaround using a fake timer (1ms is sufficient), in order to give sufficient time for the Tweener to 'know' the new content list:

  -updated dataprovider

  -wait (1ms)

  -invoke scrollToIndex()

  (I don't like to use the timer to random "wait" but... works great here)

  I don't know if it will work for all cases, I still don't know if it's a bug, or if it's the way I use QNX list inside a spark (by using QContainer of Renaun) project, but the workaround is easy and the result is very nice (as expected!) (Thanks to the QNX library).

• Dates with no thumb nails in the list of 'Moments '.

  Have deleted (totally) pictures of a 'Moment' but the date still appears in the list of 'Time' (sidebar selection is 'Photos'

  When you scroll the program list of the 'Moments' will crash when it encounters a 'moment' date only

  Please explain what you see

  and it would be good to get up-to-date with OS X 10.11.4 and Photos 1.5 - OS X 10.10.5 is four day behind and missing many new features and bug fixes

• Automatic scrolling of the list of favorites on the start menu to stop before you reach the bottom

  I open the start menu, point the mouse on the Favorites bar and keep the cursor under the small arrow pointing down at the bottom of the list of favorites, as well as the list of bookmarks automatically scrolls down. But after scroll down a number of bookmarks, automatic scrolling stops before reaching the bottom of the list of favorites, view the rest of the empty list. I removed a lot of unnecessary bookmarks in the Favorites folder in Documents and Settings, but this does not resolve the issue. I would like suggestions for this problem, which I have not come across so far. I ran CHKDSK disk cleanup and defragged the volume of disk hard, but in vain. I have Windows XP Pro SP 3 with IE8 installed on my computer.

• Loading data into the list when necessary

  HI all,

  I'm a huge display of data from database in the list,

  any ideas?

  Thank you

• Complex itemRenderer (list in the list), how can I disable scrolling?

  Hey people,

  so im struggeling for a while with a scrolling problem now.

  I'm developing an application flex with a few complex views. On points of view is like a word document view. It extracts data from the database, represents the specification. You can also modify the data in this view "word". Basicially, it should work like microsoft word. This point of view works fine but I have a problem with it: scrolling!

  To achieve this point of view, I have created a complex ItemRendererClass that contains another complex ItemRenderClass. Imagine it like this >

  -List of chapters (itemrenderer)

  -Chapternumber + titrechapitre

  -ChapterText

  -ChapitreGalerie

  -List of data (itemrenderer)

  -Requirementnumber

  -RequirmeentText

  -Photos

  -lots and lots of attributes

  -...

  Overall, I'm really happy about how the view 'word' & editor works but if im scrolling down and im on the second list, which is a list of the requirements I can't scroll more, when the mouse is on the list item, I can scroll again. What I did is use virtuall layout on both lists for performance reasons and the second height of lists is a 100%, so the second wheel never appears. I tried to disable scrolling second of the second list with 'this.scroller.setStyle ('verticalScrollPolicy', 'off'). But nothing happens. I want a normal scrolling behavior, means that it shouldn't matter where, in the 'wordview"mouse is that I want to scroll as if it were a single list and not 2 lists.

  I would appreciate a tip where I should look for advice, or maybe someone I the community has faced the same problem.

  Thank you

  Markus

  Thanks for your advice.

  I solved the problem in another and for me more easy way.

  What I did that I created a skin for the second list. In this skin, I just removed the scroller component. In addition to this, I had assigned the scrolling in the second for the parent of the list component.

  Works like a charm so far.

  Thank you

• Be able to scroll using the list without Scrollpanel

  I'm very new to actionscript 3.0, so I can't manage custom components so I just use given to me through professional flash components.

  Just as the title says, I want to scroll a list by clicking down and move the mouse up and down (almost like touchscreen model scroll eg. iphone, andorid, ipad). I tried startDrag() after the addition of EventhandlerI (ListEvent.ITEM_CLICK) to the list, but it would start by dragging the ENTIRE no list not by the data in the list. If my explanation is not clear I will be happy to be able to answer your question! So basically I don't want to see skin scrollpanel right. If there is a way to create this scrolling effect all possible ways, it would be a great help! Thank you

  I thank you,

  This will help you get started:

  var m:Number;
  var b:Number;

  setTimeout(paramsF,100,grid.y+10,0,grid.y+grid.height-10,grid.maxVerticalScrollPosition);

  grid.addEventListener (MouseEvent.MOUSE_OVER, overF);
  grid.addEventListener (MouseEvent.MOUSE_OUT, outF);

  function overF(e:MouseEvent):void {}
  addEventListener (Event.ENTER_FRAME, scrollF);
  }

  function outF(e:MouseEvent):void {}
  removeEventListener (Event.ENTER_FRAME, scrollF);
  }

  function scrollF(e:Event):void {}
  var n: Number = m * mouseY + b;
  If (n<>
  n = 0;
  } else {if(n>grid.maxVerticalScrollPosition)
  n = Grid.maxVerticalScrollPosition;
  }
  grid.verticalScrollPosition = n;
  }
  function paramsF(x1:Number,y1:Number,x2:Number,y2:Number):void {}
  m = (y1 - y2) /(x1-x2);
  b = y1 - m * x 1;
  }

• Select the list box file and read the data from file

  I can list the files in the folder in the listbox

  1. I want to just list file .txt files

  2. How can I read data from the selected file (.txt)?

  I think that's what you want, enter a model in your list of files vi (for example, *.txt) and then just use File.vi text of reading by using the selected item in the list box (double click on event or value change) and use the starting for the vi records list path.  I have included a crude extract for your pleasure.

• By programming the auto scroll value multi-column list boxes?

  I have a Multi column list box control that I put off (for indication only) which is used to show the progress.

  When a profile is loaded in the list box if this profile causes the scroll bar to become active it's obviously disabled and if the user cannot scroll

  That the control is disabled, the scroll bar is also disabled is there anyway that I can programmatically on the AutoScroll scroll bar?

  Hello

  You can use the property of the listbox multicoum ' cell upper left Visible.

  If your listbox multicoloum is disabled you can put vertical cursors or something on the front and give the value of the cursor to the line/Coloum (vertical scrollbar) and Coloum for the horizontal scroll bar to the "cell upper left Visible.

  Hope this helps

• If I click on Favorites and then scroll through the list of favorites, it does not show the entries in each file.

  * Original title: to access Favorites

  If I click on Favorites and then scroll through the list of favorites, it does not show the entries in each file but suddenly close showing the list of favorites. . I use Chrome and it happened all of a sudden. It was functional this morning. All the advice to fix this will be greatly appreciated

• Images on the screen in the list update only after scrolling to the rank of the list instead of updating automatically after each image is uploaded (delayed image loading)

  1. I started a lazy image loader to download images in drawListRow and passed the url of the image to download reference.

  2. After downloading the respective bitmap in the lazy image loader, I cancelled the list (called by using a reference to the screen where images are to shoot) using a thread event as follows:

      UiApplication.getUiApplication().invokeLater(new Runnable() {
              public void run() {
                  _list.invalidate();
              }
          });
  

  But my images are updated on the screen until I scroll over the line in the list.  I also tried to use _list.invalidate (index) to invalidate each line once the image is drawn to this particular line, but it does work and does the same thing as _list.invalidate ().

  I want the images to be updated without scrolling, and as soon as they are downloaded. How do I get there?

  Valuable contributions will be highly appreciated.

  UiApplication.getUiApplication () .invokeLater (new Runnable() {public void run() {_list.invalidate ();})            }        });

  use invokeAndWait instead of invokeLater and check if it works or not?

• Throw the list "cannot access a property or method of an object. null reference" during the scrolling of the white spaces

  Follow these steps:

     import flash.display.Sprite;
  
      import qnx.fuse.ui.listClasses.List;
      import qnx.ui.data.DataProvider;
  
      [SWF(height="1024", width="600", frameRate="30", BackgroundColor="#000000")]
      public class test3 extends Sprite
      {
          public function test3()
          {
              var l:List = new List();
              l.dataProvider = new DataProvider([{label:1},{label:2}]);
              l.setPosition(200,200);
              l.width = 200;
              l.height = 200;
              addChild(l);
          }
      }
  

  And run the application.

  Point the finger just below the last line of the list, and then drag upward or downward.

  You get this:

  TypeError: Error #1009: Cannot access a property or method of a null object reference.
      at qnx.fuse.ui.listClasses::List/resetCellState()[E:\hudson\workspace\GR2_0_0_AIR_SDK_API\src\qnxui\src\qnx\fuse\ui\listClasses\List.as:2532]
      at qnx.fuse.ui.listClasses::List/deselectCellDown()[E:\hudson\workspace\GR2_0_0_AIR_SDK_API\src\qnxui\src\qnx\fuse\ui\listClasses\List.as:2337]

  How I not imprison it? Is this a bug of the qnx.fuse.up.listClasses.List component?

  After typing this post, I went back to the SDK download page and noticed there is a new SDK available (as dated February 3, 2012) 2.0.0. I used the previous version dated SDK Date January 16, 2012.

  So I advanced and upgraded to the latest version of the SDK, and this error no longer occurs.

  It must have been a bug.

  So I solved (kind of) my problem... Kudos to me... ha!

• Maps JSON data with two data in the list

  Hey all,.

  Been working with JSON data and informing the lists for a some time now, but im stuck now on a single set of data.

  The data structure is the following:

  [
       {
            data: {
                 children: [ {
                      {}
                      {}
                      {}
                 } ]
             }
       }
  
       {
            data: {
                 children: [ {
                      {}
                      {}
                      {}
                 } ]
             }
       }
  ]
  

  The data that I take care of normally contains one of these structures and not 2 as in the above data. So what follows could could work:

                                  const QByteArray response(reply->readAll());
          ArrayDataModel *model = new ArrayDataModel();
  
          bb::data::JsonDataAccess jda;
          QVariantMap results = jda.loadFromBuffer(response).toMap();
          QVariantList children = results["data"].toMap()["children"].toList();
  
          model->append(children);
          mListView->setDataModel(model);
  

  However, it is now giving me an empty list. So how can I limit the above code to analyze and insert only the 2nd set of JSON data in the list?

  Please let me know if it needs to be clarified. Any help is appreciated. Thank you!

  Hello

  It contains a list of maps. Have you tried something like the following:

  bb::data::JsonDataAccess jda;
  QVariantList results = jda.loadFromBuffer(response).toList();if (results.size() >= 2){
      QVariantMap secondSet = results.at(1).toMap(); // to get the second map
      QVariantList children = secondSet["data"].toMap()["children"].toList();
      model->append(children);}
