ListView - Is GroupDataModel a model 'by default'?

• Fill ListView using the C++ model

  Hello

  Sorry to bother, I guess my question must be pretty basic, but I'm new to bb10 SDK,

  What I intend to do is to show in a listview items, I calculated in C++. (In C++, because the logic for calculating them was quite complex)

  There, in the QT doc, you have exactly what I dream of:

  https://Qt-project.org/doc/Qt-5.1/QtQuick/QtQuick-modelviewsdata-cppmodels.html

  Unfortunately, I have several questions:

  -ownership model, seems to exist. But I guess we use dataModel in our context, right?

  -J' I also need to get the declarative context of the QmlDocument which I think is correct.

  -the delegate property also doesn't seem to exist, but I understand that I must use instead ListItemComponents ( http://developer.blackberry.com/native/reference/cascades/bb__cascades__listitemcomponent.html)

  But I'm still confused on how I should provide the data for the list view.

  Now, when I expose my QList of DataObject, as described in the Doc of QT and which gives as data to the dataModel is told that he cannot "affect QDeclarativeListReference to bb::cascades:ataModel."

  So I guess I have to use a QListDataModel instead of use a Qlist <>, or?

  Well, any help in pointing me to the right documentation would be very appreciated!

  Thank you

  fill us our data model in c ++ as well.

  For this, we use a Q_INVOKABLE method that gets the listview as a parameter.

  The ListView itself is created in QML.

  ListView* listView = dynamic_cast(listViewParameter);
  GroupDataModel* model = dynamic_cast(listView->dataModel()); if (model) {        model->clear();    } else {        model = new GroupDataModel(QStringList() << "sortParameter");        model->setGrouping(ItemGrouping::ByFullValue);        listView->setDataModel(model);    }//calculate stuffmodel->insertList(stuff);
  

• Models of default PCB

  Ultiboard provides a way of redefining what contains the default PCB project?

  Now, as soon as you open Ultiboard and select "create new project... ', it opens to the design with no space.  What is cool at the moment, you draw your rectangle Board, add a title block, etc, etc, life goes on.

  However, we seek to keep our design as possible consistent layout between the different engineers.  So, what I would do is create a contour of the blank map, add a title block and any other area of descriptions of text that I want and then save it as the new default project template.  This way, the next time I create a new Board of Directors, I'm starting with my preconfigured cartridge and description of field arrangement.  Is this possible?

  Hello

  Multisim/Ultiboard includes the ability to create user models, essentially a Multisim file (for your schema) and Ultiboard file (for the presentation of PCB). Details can be found at:

  Quickly prototype with Multisim and Ultiboard user-defined models

  I hope this helps!

• Notify the ListView data in the model have changed

  Hello!

  I know this question has been asked several times, but I have yet to find anything satisfactory.

  I have a ListView, filled with a QListDataModel.

  After some time I update an element of the model. So far, the only way I found to the ListView so that this change is to delete the model and then reappend all elements. But the problem with this approach is that ListView Flash and scroll to the top of the page. Is there anything better to just say ListView that it should update the visible elements?

  Thank you

  Well, I just signal myself in the WRITE method and it works.

• Re: What is the model of default keyboard in a Qosmio G30?

  Hello
  I have a Qosmio G30-155 which I had arranged with additional partitions. Recently, I did a complete reinstall of Windows Vista, but I have not used the Vista DVD provided with my computer because it would destroy my partitions. So, I used a standard DVD of Vista. Everything works well except two questions: the computer is not responding to shortcut keys, or IR remote. Laptop infiltrates the IR signals, because when one presses a button on the IR remote control, a few lights in the remote and computer. However, nothing else happens.

  I installed several configurations of the packages 'remote control manager', "Added value package" and "Support" button, nothing helps.

  I checked the Device Manager, and my keyboard appears as a "PS/2 Standard keyboard. I guess that this setting is false, because this keyboard would not have access keys. So, this setting could be cause my problems.

  Can someone tell me which type of keyboard G30s were?

  Thank you and best regards

  I agree with Akuma
  There is no special keyboard drivers and those drivers are not needed.,.
  The Windows operating system, no matter if it of Vista or XP, uses the Microsoft keyboard driver.

  To enable the keys FN and Toshiba control buttons the VAP (value added package) must be installed

  You must ensure that you have chosen the correct drivers for the laptop G30.
  The G30-155 seems to belong to the series of PQG32E so chose exactly this model in the form of download number.

• After you remove models 5 default the configuration section is now disabled.

  Sorry, but the! doesn't seem to work properly, you have to click through.
  
  The first column is a dimension, the following 2 are measures of a fact table.
  
  Note how the style is different? I don't want to... I want to keep it consistent.
  
  Using true firebug, I note the different classes used.
  
  Column dimension

  <th style="background-color: rgb(231, 231, 247); font-size: 9px; color: rgb(0, 51, 102);" class="ColumnHdg" scope="col" dir="ltr">Product Desc</th>

  Measure column

  <th class="ColumnHdg" scope="col" dir="ltr">Basis Amount</th>

  I grepped the web folder and could not find any reference to the style tag in the Dimension column. These statements of inline css are the substitution of the ColumnHdg class, but I can't find where that is defined. It does not appear that the files have changed in the msgdb or res files (timestamp is the date of installation).
  
  So my question is, where else can I look to see where this style attribute could apply?

• Model by default - table cell has no border when the cell is empty: IE6

  Hello
  
  I use the model: dark blue with the model of report of ratings in the region.
  I have a problem in displaying the result in IE6.
  
  When a cell is empty, I have white border in my table instead of edge banding.
  
  Do you know where I can fix this?
  
  Thank you
  
  Roseline

  Roseline,

  You must locate the corresponding css file and look for something like it's - t10 is the number of my theme so replace it with your theme

  Th.t10ReportHeader

  TD.t10data

  TD.t10dataalt

  and add the following code to the css classes:

  empty-cells:show;border-collapse:collapse;

• Cancel/model of default slide

  Hello

  I have created a caption box in one of my slides and accidentally selected, apply to all > slides? Apply to all slides. Now I have that same box of legend (apparently) incorporated in each subsequent slide of the project. I can't move, delete or even highlight the area, because it seems to be a background image.

  
  I tried to change the background image for the slide service, but this removes the images that are already there.

  When I try to insert a blank slide, it inserts a slide with this same box integrated in it. The box does not appear in the film strip, only in the editing pane.

  Anyone know how I can cancel the change I made?

  I'm glad that my intuition was good

• WORDPAD: HOW TO DEFINE MODEL DEFAULTS TO SINGLE SPACE?

  My computer came with Wordpad.  The model 'by default' seems to be set to double space and I don't know how to change it so that the default value is a single space (ie. like my ad here). Itdoesn't seem to be a 'box' in the menu at the top of the page - on the same line as the font settings/size - titled ' line spacing: change the spacingbetween of text lines ") but it doesn't seem to work ! Or, at least, I don't know how to operate it. I tried to play with the settings made here, but nothing that I don't seem to make any difference.

  In the line spacing box, you should be able to select; 1.0, 1.15, 1.5 or 2.0

• Change default model navigation in the portal generator

  Hello

  I develop a portal 11.1.1.8 Webcenter portal using the portal generator. I created a new Navigation model.  Now, I want to assign as the model of default navigation for the portal, I had created.

  When I go to the link to Administration-> settings, Navigation is not editable. Other things like Page Template, Skins etc can be changed. Is there a way I can change the value by default model of Navigation for my portal?

  According to the link here: http://docs.oracle.com/cd/E29542_01/doc.1111/e27603/portadv_admin.htm#CHDDEIIA

  The navigation model for a particular site cannot be changed after creation. Instead, we can change the default Navigation model based on our needs.

  dataName is a QVariantMap variable. The data are available in the variable, I checked that.

  The following, almost identical to yours works for me. There are a few things in your code, which I don't see, so it is difficult to check every detail. First, create a new application and replace applicationui.cpp, applicationui.hpp and main.qml with my code and then test it. If it works, check if your code against mine. If not, let me know the device and the version of the OS that you are testing.

• Update of ListView dummy image using images from URL http

  Hi guys...

  Please help me with this.

  I have created a ListView in QML file and filled with data received from a webservice. Since this web service provides all the images, I have to place a dummy image at this location. Then I used another method to retrieve images of the url. Now, I got the image in my CPC file. But I could not update my listview. I tried several methods. But failed.

  Here is my code snippet.

   ListView {
                  id: listView
                  objectName: "listView"
  
                  dataModel: ArrayDataModel {
                      id: myListModel
  
                  }
  
                  // Override default GroupDataModel::itemType() behaviour, which is to return item type "header"
                  listItemComponents: ListItemComponent {
                      id: listcomponent
                      // StandardListItem is a convivience component for lists with default cascades look and feel
                      StandardListItem {
                          title: ListItemData.postText
                          description: ListItemData.postDate
                          status: ListItemData.filePath
                          imageSource: "asset:///images/4.png"
                      }
  
                  }
                  layoutProperties: StackLayoutProperties {
                      spaceQuota: 1.0
                  }

                  verticalAlignment: VerticalAlignment.Fill
  
              }

  Thanks in advance
  			 
  You can pass a QByteArray of image data coded directly to an imageView in the image property, set of QVariant::fromValue (). However, in your case you can place the uri to which you saved the image and not the bytes. Advantage: cascades puts these images in cache. If you use deterministic file names, you can avoid any networking calls or loading of images when only the populated list of point sier after be recycled.
  
  img.loadFromData(buffer);
  img = img.scaled(40, 40, Qt::KeepAspectRatioByExpanding);
  img.save(QDir::currentPath() + "/shared/camera/img.png"), 0, 75);
  
  QImage can do all this for you, without permutation of bytes.
  All you have to do is then updated the datamodel.
