Re: [SailfishDevel] Hidden information to ListView

[Andrey Kozhevnikov]

what the problem? You not forced to use all fields in any visual elements.

You can use model.get(index).fieldname for getting any field from model

Hi Chris and others,

yes I understand how to add more than one fields in the same append
command. The problem is that I would like to add hidden (not visible
for user) per ListItem. In my example which I send in my previous mail
was only one label which is visible for user, but how to add variables
inside the ListItem (row ID  of DB and other information) which I can
access from other functions like when deleting the item from screen
and db at the same time.

I tried to add inside ListItem this way:

delegate: ListItem {
    id: contentListItem
    property int itemId: itemId

    Label {
        text: itemValue
    }
}

and in the append({"itemValue": items.rows.item(i).itemValue,
"itemId", items.rows.item(i).itemId})

However, later when I'm calling:
contentItem.isDefault returns undefined.

I can't figure out what I'm doing wrong. I just want that I can delete
the item when I'm pressing the ListItem and getting the dropdown where
is selection Delete.

I hope that someone could help me with this.

Kind Regards,
Jukka

It is very easy to add multiple roles / fields with the same append command.

Here is an example culled from one of my apps:


var db = DB.DataModel();
var rs = db.getContacts(area_id, template_id);
for(var i = 0; i < rs.rows.length; i++) {
    contactModel.append({"name": rs.rows.item(i).name, "phone":
rs.rows.item(i).phone, "primary_contact":  rs.rows.item(i).primary_contact,
"contact_id":  rs.rows.item(i).id});
}

Zitat von "Jukka Heikkilä" <jut...@gmail.com>:

I'm creating page which shows some information which is returned from
local storage. I have successfully created the next code which will
work:

Page {
     root

     Component.onCompleted: {
         //External Function which return the items from Local Storage
         items = DB.listItems();

         //Adding items to list view
         for(var i = 0; i < items.rows.length; i++){
                 listItems.model.append({"itemValue":
items.rows.item(i).itemValue})
         }
     }


     SilicaListView {
         id: listItems
         model: listModel

         VerticalScrollDecorator {}

         delegate: ListItem {
             id: contentListItem

             Label {
                 text: itemValue
             }
         }
     }

     ListModel {
         id: listModel
     }
}

I would like to include some hidden values (e.g. DB row ID) for later
usage, but is there possibilities to include extra data with same
append command to the ListItem? I know the properties, but I haven't
managed how to pass the variables in it.


I would be grateful for your help.

Kind Regards,
Jukka
