• ListView problem: scrolling non-stop

  Hello friends,

  I get some problem with ListView in ScrollView ListView doesn't stop scrolling.

  I want to put some of the views (for example, Label, textArea Image) in the vertical stack layout container & add a list at the end of the container, so that all opinions can scrolls.

  But I get unexpected results that everything is ok, but my view of the list doesn't stop event of scrolls of the item in the scrolling list.

  If I add some other view as tab after ListView then it never reached.

  Can someone give me a solution for this.

  Thanks in advance

  I use the following code for QML

  import bb.cascades 1.0

  {Of container

  background: Color.Yellow
  maxHeight: 1000
  preferredHeight: 1000
  ScrollView {}
  maxHeight: 1000
  preferredHeight: 1000
  {Of container
  {Of container
  topPadding: 10
  leftPadding: 10
  rightPadding: 10

  {Of container
  layout: {StackLayout}
  direction: LayoutOrientation.LeftToRight
  }
  TextField {}
  hintText: qsTr ("toEmail/Mobile number Email/Mobile Number") "") "
  }
  ImageButton {}
  defaultImageSource: ' images/add.png.
  pressedImageSource: ' images/add_focus.png.
  verticalAlignment: VerticalAlignment.Center
  horizontalAlignment: P
  }
  }
  {Of container
  topMargin: 10
  layout: {StackLayout}
  direction: LayoutOrientation.LeftToRight
  }
  ImageView {}
  preferredWidth: 120
  preferredHeight: 90
  }
  TextArea {}
  maximumLength: 50
  hintText: "title."
  preferredHeight: 180
  }
  }
  background: Color.LightGray
  preferredHeight: 720
  }

  {To ListView
  dataModel: {ArrayDataModel}
  ID: contacts
  }
  }

  onCreationCompleted: {}
  contacts. Append ("ABAC");
  contacts. Append ("ABAC");
  contacts. Append ("ABAC");
  contacts. Append ("ABAC");
  contacts. Append ("ABAC");
  contacts. Append ("ABAC");
  contacts. Append ("ABAC");
  contacts. Append ("ABAC");
  contacts. Append ("ABAC");
  contacts. Append ("ABAC");
  }
  }
  }
  }

  As far as I know, using listview in scrollview will cause infinite scrolling. To resolve this issue, try to set the height of the listview. You can also try to set the height of the listview based on the number of records by using contacts.size ();

  It will be useful.

• To reorder ListView problem

  Hello

  10.3, reorganize the listview items is now possible via the RearrangeHandler class (https://developer.blackberry.com/native/reference/cascades/bb__cascades__rearrangehandler.html)

  I noticed during the implementation of this class that rearranging works only when the elements below are trained upward. When the elements at the top of the page it is slipped down the list, none of the signals (started, completed, updated, abandoned) don't are not fired. The user interface changes automatically isn't.

  Both the sample application or my implementation does not work when the elements above are trained more far.

  Can a BlackBerry person take a look at this? Thanks in advance.

  I tested on the official bone on the passport and classic version.

  I tried this sample and I see the same behavior that you are.  I sent the question to our development team to resolve.

  10.3.1 signals are fired, but you can not yet move items down.

• Prevention of ListView, select the element for multi select

  How do you keep a user to select specific items during a statement select multi. You can use the MultiSelectHandler to do?

  I have essentially two types of elements. Setting caching and QUERIES.  When the user performs a Multi Select on a cached item... I want only their selection to other cached items.  Even if the user is running a Multi Select statement on an item not cached... I want only their selection of other items not cached.

  Is anyway to do this?  Been Googling for half an hour and can't find that everything about this use case.

  Since I use an element of custom list, I went to this subject a little differently. My CustomListItem implements a ListItemListener. I've implemented the select method as such.

  void CustomStandardListItem::select(bool select) {
      bb::cascades::ListItemListener* lil = static_cast(m_sli);
      bb::cascades::ListView * view = qobject_cast(this->parent());
  
      if (view->multiSelectHandler()->isActive()) {
          bool isCached = view->property("isMultiSelectTypeCached").toBool();
  
          if (m_cachedImageView->isVisible() && isCached) { // is cached.. allow selection of other cached objects only
              lil->select(select);
          }
          else if (!m_cachedImageView->isVisible() && !isCached) { // is not cached.. allow selection other cached objects only
              lil->select(select);
          }
      }
      else {
          lil->select(select);
      }
  }
  

  The dynamic property 'isMultiSelectTypeCached' is just a bool on ListView value that gets defined the type of ListItemComponent. It could have just as well been the type of ListItemComponent.

• ListView - problem DockLayout

  When I use a viev list in a layout of the dock it dosent fit properly.instead, it collides with the first container.

  should he not just after the first container since I updated the verticallayout Center for container parent of the listview.

  Thanks in advance.

  When using the dock layout object are added as layers and the order given in qml are important. Your code adds a listview on top of the first box. What is happening, is that you will not be able to capture the actions for this button and once filled, the listview will overlap graphically the key 1.

  Below is an approach valid at your intent:

  import bb.cascades 1.2
  
  Page {
      Container {
          layout: DockLayout {
          }
  
          Container {
              id: cont
              bottomPadding: 73
              verticalAlignment: VerticalAlignment.Top
              horizontalAlignment: HorizontalAlignment.Fill
              Button {
                  bottomMargin: 0
                  text: "1.button"
                  horizontalAlignment: HorizontalAlignment.Fill
                  onClicked: {
                      console.log("dsds");
                  }
              }
              Container {
                  //background: Color.Blue
                  ListView {
                      dataModel: XmlDataModel {
                          source: "asset:///currencies.xml"
                      }

• Problem first elements

  I've added several elements in a video project.  I decided to delete the last item.  I can't delete the beginning of the video clip form.  When I preview the it, it stops at the first frame of the clip removed.

  Why is this happening?  I can solve this problem?

  Thanks for the follow-up.

  With regard to the trial of the 13 items first... all imports in it will have the watermark of Adobe as seen in the edit box monitor.

  1. you can't you get rid of this watermark Adobe from exports of the first 13 items test (either export to the file saved in the computer

  hard drive or burn to disc).

  2. you can get rid of the tattoo Adobe Premiere elements 13 trial of the project file (.prel). For this you need 13 items first purchased.

  a. open the project first elements 13 tryout file recorded in first 13... bought items then chronology Menu/delete rendered files... the Adobe watermark is based on this project.

  or

  b. open Premiere elements project file 13 tryout recorded in first 13 bought items... and then do nothing but continue the project. So we have

  found that just opening the project of tryout in the acquis automatically removes the watermark of Adobe.

  Determine which of the two that works for you.

  There is no guarantee that a project created in an earlier version can be opened in a later version. But you can try. But do this by using a copy of the project file of the previous version. Once the project from the previous file is changed in the second version, you can't go back and change the edited version project subsequent to the previous version.

  Please let us know if you're OK with the above information. If this isn't the case, please do not hesitate to ask questions and seek clarification.

  Thank you.

• Problem Background Image

  Hello
  I'm using a custom theme in APEX 4.0 on Oracle 10 g. I'm trying to add a background image to a page, and I find that the theme does not appear the image correctly. I need to click on the background image view to see the actual image...
  
  I know there is a way through css to override the existing background image/color, but today I simply didn't see / get it...
  
  Can anyone offer a suggestion?

  The background properties are applied to the body according to your stylesheet incorporated. The problem is that the body is invisible behind all this fancy theme UI widgets dan.

  Various s divon the page have styles online specifying absolute positions and z-index values that display them in front of the body of the page and have the .ui-pane-layout class that specifies the gray background. Override this rule with:

  .ui-layout-pane {
    background-color: transparent;
  }
  

  and the body with your background image becomes visible.

  On the other hand, put the background image on the main content div can be closer to what you're trying to achieve? Replace the body selector in your existing rule by div #delta - content of the page:

  div#delta-page-content {
    background-image: url(wwv_flow_file_mgr.get_file?p_security_group_id=9023722216290979&p_fname=ata_background.png) !important;
    background-repeat: no-repeat !important;
    background-attachment: fixed !important;
  }
  

• BB10 Image problem

  I encountered a problem trying to update a qnx.fuse.ui.display.Image bitmapData:

  Here is my code:

  function update( bmp:Bitmap ):void{ var bmd:BitmapData = bmp.bitmapData;
  
      if ( bmd is BitmapData )
      {
          trace( _image.width, "x", _image.height, bmp.name, bmd.width, "x", bmd.height );
  
          _image.setImage( bmd );
          _image.visible = true;
  

  and here is the trace output:

  329 x 256 instance1872 341 x 256
  ArgumentError: Error #2015: Invalid BitmapData.
      at flash.display::BitmapData/get width()
      at qnx.fuse.ui.display::Image/getRawPreferredSize()[E:\hudson\workspace\BB10_0_09-AIR_SDK_API\src\qnxui\src\qnx\fuse\ui\display\Image.as:142]
      at qnx.fuse.ui.display::Image/setImage()[E:\hudson\workspace\BB10_0_09-AIR_SDK_API\src\qnxui\src\qnx\fuse\ui\display\Image.as:337]
  

  The new bitmapData seems to be ok, because the height and width are non-zero, so it seems to go to a previous instance of bitmapData (which has been replaced).

  I tried to keep a global reference to the old bitmapData, but same result...

  Suggestions please...

  to fix this, I added the following:

  if ( _image.bitmapData )
  {
      try
      {
          var testWidth:int = _image.bitmapData.width;
      }
      catch( e:Error )
      {
          var index:int = getChildIndex( _image );
  
          trace( "remove image at:", index, _image.x, _image.y, _image.hAlign, _image.vAlign );
  
          removeChildAt( index );
  
          _image = new Image();
          {
              _image.fixedAspectRatio = true;
          }
          addChildAt( _image, index );
  
          invalidateDisplayList();
      }
  }_image.setImage( bmd );
  

  ugly but necessary...

• Display of images in a ListView problem

  Hello world

  I'm trying to display images in a grid (GridListLayout) in a ListView component (as in This example). However, it just displays the paths to the images I try to view (if it is not clear for you take a look at attachment 1). What I am doing wrong?

  In my data model, you can find this method of data:

  QVariant ComicsDataModel::data(const QVariantList& indexPath)
  {
      return QVariant("assets/images/legodude.jpg");
  //return coverList.at(indexPath[0].toInt());
  }
  

  The commented code returns the actual filepaths (absolute paths), but who doesn't either. Of course, I have included the image in the assets/images folder. The ListView is specified as written below.

              ListView {
                  objectName: "coverListView"
                  layout: GridListLayout {}
  
                  listItemComponents: [
                      ListItemComponent {
                          type: "image"
  
                          ImageView {
                              imageSource: ListItemData
                              scalingMethod: ScalingMethod.AspectFill
                          }
                      }
                  ]
              }
  

  Thanks for the help! All of the examples to work with images using XML as datamodel, I use a custom data model.

  Annex 1:

  Probably your datamodel custom does figure not correctly return the correct values in the DataModel::itemType() function - make sure you return 'image' properly in your overload of itemType() - or use the equivalent ListView callback function in QML
