Re: [SailfishDevel] Hidden information to ListView
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});
}

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

Re: [SailfishDevel] Hidden information to ListView
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
