• Binding a list with QImage & PixelBuffer data display view Image

  Hello

  I need to develop a photo gallary as application. I need to load images different lists of grid.

  I can paint pictures on a single ImageView using PixelBufferData.

  PixelBufferData pixelBuffer = PixelBufferData(PixelBufferData::RGBX, width, height, width, qimage.bits());
  
      Image image = Image(pixelBuffer);
      imageView->setImage(image);
  

  Now, I need to tie this with a list of grid view. How to get specific ListItem Image view painting.

  ListView { id: albumsListView objectName: "albumsListView" layout: GridListLayout { columnCount: 5 }
  
  dataModel: XmlDataModel { source: "models/album.xml" }
  
   listItemComponents: [ ListItemComponent { type: "album" MyListItem { } } ]
   
  

  MyListItem is a custom component:

  Container { id: myItemContainer layout: DockLayout { } Container { layoutProperties: DockLayoutProperties { horizontalAlignment: HorizontalAlignment.Fill verticalAlignment: VerticalAlignment.Fill } layout: DockLayout { } ImageView { id: coverImageView objectName: "coverImageView" imageSource: ListItemData.coverImage preferredWidth: 250 preferredHeight: 250 } Container { background: Color.Black opacity: 0.7 layout: DockLayout { } layoutProperties: DockLayoutProperties { horizontalAlignment: HorizontalAlignment.Fill verticalAlignment: VerticalAlignment.Bottom } Label { text: ListItemData.name layoutProperties: DockLayoutProperties { horizontalAlignment: HorizontalAlignment.Center verticalAlignment: VerticalAlignment.Bottom } textStyle { base: SystemDefaults.TextStyles.BodyText fontWeight: FontWeight.Bold color: Color.White } } } }}
   
  

  I tried to call the method onCreationComplete of imageView & ImageView onImageSourceChanged but did not work.

  Well, I managed to find the solution.

  I used just custom ListItemManager & ListItemListener update display image in list & it worked fine.

  You can see below the links for more information. Documentaion is quite good. Its very easy to understand & implement.

• Populate a list with the data previously collected

  I want to populate a drop-down list with the data previously collected in the same form. How can I do this?

  There are a variety of ways. For example, if 'stooges' is a drop-down list and 'stoogeName' is a text field, you can place the JavaScript code depending on the output of "stoogeName," event

  Form1.Page1.Subform1.stoogeName::exit - (JavaScript, client)

  Form1.Page1.Subform1.Stooges.AddItem (this.) RawValue);

• The list with many images

  Hello!

  I have a list with a lot of images in the itemRenderer, over 500.

  I use virtualization on this list.

  When people scroll quickly down, it can take a bit to load images.

  Issues related to the:

  1. in what order the list control to load images? Up and down the entire list or Topp down only the visible part?

  2. is there anyway I can give priority to a certain image to load first on others? The images have the source property set to a relative path on the server.

  3. is there anything I can do to speed up the process of loading in general?

  Thank you!

  The list does not load images, because of your item converter.  I suppose you load these images by substituting the data setter method in the rendering engine.

  When the list of the first loads it creates just enough converters to show what is in view (due to virtualization), let the top 10 items.  This means that the first 10 images will be loaded, but no other images will be loaded unless you scroll the list to expose new items.  If you want to have some images available before others so you can have your application load them if its not busy and in this way, they could be available before the user scrolls.

  Even if you were to load all images before creating the list you might seem still some flickering when scrolling because what are they are recharged in as user autour scrolls.  To remedy this, you might want to consider caching the images as they are loaded, there is an example here: http://flexponential.com/2010/01/10/caching-images-loaded-from-a-spark-item-renderer/

• I have 2 copies of open Firefox (two different windows with lots of tabs), if I reboot can I restore the two sessions?

  I have 2 copies of open Firefox (two different windows with lots of tabs), if I reboot can I restore the two sessions? I am familiar with clicking history / restoration of previous session, but do not want to reboot to let windows update to do it's thing unless I can restore the two sessions.

  guigs2 said

  If they run different profiles, then Yes.

  Thanks, but I use only 1 profile. However, I found the answer! If I restart/turn off / down pc WITHOUT closing a firefox session, he will come with the screen 'well, it's embarrassing"and list the TWO sessions to restore. The trick is not not to close before stopping! If you close them first, then you can only restore the session first (?).

• Fill the drop-down list in the SQL data source

  To extract the values you need to wait for onDataLoaded. "data" parameter is a list of cards.

  I'm on Windows 10.

  Thanks in advance for any help!

  The screen 'Open' uses Windows Explorer, so it's definitely a Windows problem.

  Try this:

  On the title bar, just above the list of files/folders (Date, Type, size) right click on the empty part of the bar and look at the context menu.

  You should see a list of the types of possible columns, the checkmarks on the possible options. There are more than 15 available date types. Try to create another column with another date than the simple 'Date' type, you now by checking the box. See if other dates are displayed.

• Fill the list with Instances

  Hi all
  
  Is it possible to fill the results in a drop-down list with the name of the entity instances.
  
  for example, I instantiated instances 4 x by the name of the child as part of the entity of children.
  

  HARRY
  BARRY
  SALLY
  LARRY

  Then on a separate screen, I want a drop-down list to be filled with the name of the child.
  
  for example
  Maybe, I have a question:
  

  what is your favourite child (which is a drop down showing 4 instance names (HARRY,BARRY,SALLY,LARRY)

  I'm on v10.1
  
  
  See you soon

  Hello

  There is a way to make this out-of-the-box, but all depends on your data model.

  I assume here that you have 2 entities, the person and the child. The child has an attribute called 'name of the child. "

  Creates a one-to-one between the person and the child relationship, that he calls "the child preferred person '...

  Then, create an individual question screen. Add a control to the "relationship of entry" to the screen in question. For the 'legend', write something like "Please choose your favorite child." For the "attribute" display, choose the name of the child.

  This will display the question exactly as you want - it will ask the user to select from a list of all children.
  Of course, if the person can have many favorite children, create a relationship one - several. However, this will display the names of the children as the boxes, because the user is now allowed to select more than one.

  If the relationship is just together, you can then use this relationship to access the name of the favourite on the level of the individual child (using InstanceValueIf), or you can run the rules that apply only to the favorite child.

  It's just a suggestion that Ive just tested in 10.3, I did 10.1 at hand at the moment but don't remember which is new to the brand (others, please correct me if I'm wrong). Give it a go, see if it works and get back to me, if it's not. If this does not work on 10.1 you should certainly consider the upgrade to 10.3 for a host of other reasons too. Otherwise, it is achievable with a custom control.

  See you soon,.

• List with useVirtualLayout = "false" and dataGroup.invalidateDisplayList ();

  Hi all

  I wonder if someone could explain this behavior:

  -J' have a list with a tile layout

  -The list is on do not use Virtualization: useVirtualLayout = "false".

  Elsewhere in the code... when I call dataGroup.invalidateDisplayList () on the list, it refreshes the list when useVirtualLayout is NOT set to false.

  Please can someone explain why this is?

  Thank you

  Probably because virtualLayout sets the property data on itemRenderers as

  they get recycled.  If once not virtual, each rendering engine is assigned its data

  It probably is to be given.  If you have dependencies on that

  assignment, he could make a difference.
