Search for an item that is created dynamically c ++

I use ComponentDefinition to create a page.

ComponentDefinition {
  id: preferences  objectName: "preferences"
  Preferences {
  }
}

C ++ I want to find this component, how do I do that?

I tried several approaches with objectName, but none were successful.

-put objectName in the definition (as seen above)

-put objectName into the brackets of the above preferences

-put objectName in the Preferences.qml

That's how I try to find page:

Page* preferences = root->findChild("preferences");

What I want to achieve is to broadcast a signal from the qml page dynamically created, which connect to a slot machine c ++ and fill the qml of c ++.

There is an example in the link that they provided;

In main.qml:

  • How can I search for all photos that have names composed of four numbers?

    OT: Help search.

    Hello, I want to seek a photo (.jpg), photography is as the name of 5225.jpg, which consists of four digits. How can I search for all photos that have names composed of four numbers? Thank you

    I don't know how to search only images that carry the 4 numbers, but I know how to find a file that is exactly 4 letters long and ends with ".jpg".

    To do this, type this in your search box (exactly as it is, including quotation marks):

    "file name:"? "jpg"

    It will search for all files that have exactly 4 characters followed by .jpg at the end.

  • GroupDataModel how to search for an item and row

    Hi all!

    I have a problem with GroupDataModel.

    I create and fill out the template as below:

    
    m_model = new GroupDataModel(QStringList() << "displayName", this);
    ...
    QVariantMap entry;
    entry["contactId"] = QString::number(contact->getId());
    entry["displayName"] = contact->getDisplayName();
    entry["icon"] = contact->getSmallPhoto();
    
    m_model->insert(entry);
    

    After I cath some report like contactDeleted (int id) and want to remove the related item of the model:

    void ContactsViewModel::onContactDeleted(int id)
    {
      //QVariantList indexPath = m_model->lowerBound(QVariantList() << QString::number(id));
      //QVariantList indexPath = m_model->lowerBound(QVariantList() << id);
      //QVariantList indexPath = m_model->find(QVariantList() << QString::number(id));
      QVariantList indexPath = m_model->find(QVariantList() << id);
    
      if (!indexPath.isEmpty())
      {
        m_model->removeAt(indexPath);
      }
    }
    

    But model will always return row to the first article! I used and GroupDataModel::find and GroupDataModel::lowerBound, but result is still the same!

    Please help me, how can I find point correct?

    Hello

    My understanding of the documentation, it is possible to search only the fields that are in sortingKeys.

    I think that GroupDataModel is the construction of indexes on these areas.

    I did some tests:

    If displayName is present in sort keys:

        GroupDataModel *model = new GroupDataModel(QStringList() << "displayName", this);
    
        QVariantMap entry;
        entry["contactId"] = "100";
        entry["displayName"] = "Alex";
        entry["icon"] = "icon1.png";
        model->insert(entry);
    
        entry["contactId"] = "200";
        entry["displayName"] = "Andrew";
        entry["icon"] = "icon2.png";
        model->insert(entry);
    

    then by displayName will work correctly:

    QVariantList indexPath = model->find(QVariantList() << "Andrew");
    qDebug() << "indexPath" << indexPath << "\n";
    // this will print (QVariant(int, 0) ,  QVariant(int, 1) ) which is
    // section 0, item 1
    

    But research by contactId won't work, because it is not present in sortingKeys.

    If you add contactId to sortingKeys:

    GroupDataModel *model = new GroupDataModel(QStringList() << "displayName" << "contactId", this);
    

    then by searching only by displayName will no longer work. Find() maps values to keys, it will only return entries with empty contactId. But lowerBound() can be used instead:

    QVariantList indexPath = model->lowerBound(QVariantList() << "Andrew");
    qDebug() << "indexPath" << indexPath << "\n";
    // this will return:
    // indexPath (QVariant(int, 0) ,  QVariant(int, 1) )
    

    Please note that the lowerBound is not a complete replacement for find. It returns a suggested for element insertion index. So if she is unable to find a match, it will return (0, 0) like suggested insertion point, but not a row empty.

    When you have multiple sort keys the code depending on type of work to find a name:

        GroupDataModel *model = new GroupDataModel(QStringList() << "displayName" << "contactId", this);
    
        QVariantMap matchMap;
        //matchMap["contactId"] = "200";
        matchMap["displayName"] = "Andrew";
        QVariantList indexPath = model->lowerBound(matchMap);
        qDebug() << "indexPath" << indexPath << "\n";
    

    But if the name is not found lowerBound will return (0, 0) - a proposed insertion point. Is not possible to differentiate the value of return "not found".

    But if you try to provide a contactId

        matchMap["contactId"] = "200";
        //matchMap["displayName"] = "Andrew";
    

    It will not work, because it searches in the order in which the sortingKeys have been reported.

    In this case, it will try to 'empty' QVariant DisplayName of match, find nothing and will be (0, 0) return as insertion point proposed without even trying to match contactId-s.

    The find() function is not appropriate as well because it performs the exact match on all fields and requires that all sortingKeys to be defined.

    I hope I have not confused you completely now!

    So, the conclusion seems to be:

    Find() cannot find an exact match and compared all the keys of the supplied with keys in sortingKeys. If values are omitted it is expected that they are NULL in the model.

    lowerBound() returns a suggested insertion or (0, 0) point, if nothing has been put in correspondence. He compares the values passed to it with the sort of keys from left to right (if the first sortingKey did not match it does not compare).

    If these methods are not well suited for finding a specific key value. A possible workaround is an iteration model entries manually and by comparing their values, but it's slow.

    I suggest to create your own datamodel by inheriting from the class DataModel. It is not very difficult, and you can implement any kind of search in there.

  • Properties to search for parent items

    Hi all

    Who are the properties that must be used/filled in the following points for parent items.

    Category: property that is important to know which category and catalog this category belongs?

    Product: what property should be used to determine to which category and catalogue belongs to this product?

    SKU: what property should be used to find out which product, category, and the catalogue of this Reference belongs?

    What is the meaning of Scripture = 'false' in customCatalog.xml?

    see you soon

    Catalog file to-> catalog-> categories-> product-> Sku

    1. create SKUs.

    2. create the inventory and add above sku in sku inventory property.

    2. create the product and add above sku in SKU of the product property.

    3. create category and add above produced in 'fixed products of the child' property of this category.

    4. create the catalog and add above category in the property "rootCategories' of the catalogue.

    5 create catalog file and add the catalog in the "kids catalogs" property of CatalogFolder.

    You therefore need to create xml in a way that avoids dependencies found problematic situation.

  • How can I search for a color that isn't in the color scheme? (CS 5.5)

    I have a client who has used a certain color in a series of textfields in the entire document.

    Color consists of all 4 colours CMYK and must be just Keycolor. However the color is not in color chart menu, so marking it and change it don't work. I downloaded a script that would work, but he couldn't find the colors that were in the Swatches palette. (' Find / Change color / overprint "version 1.2).

    Of course, create a similar color and the addition of witnesses does not work.

    Is there anyway that I can search for color, or should it really be done manually.

    Best regards

    You can search only for real samples, which actually existing. Don't panic: use 'Add Unnamed colors' in the menu drop-down panel Swatch to get a list of all the manually applied colors.

    As you change each of them the same color, you have yet to use find/replace. Just remove the new colors and select the one that you need in the ' replace by ' the dialog that appears.

  • How can I change the code of the search for a site that I added to the search bar?
