Title:
[ListItems] Default property being "children" brings some
inconvenience
Status in Ubuntu UI Toolkit:
Fix Released
Status in “ubuntu-ui-toolkit” package in Ubuntu:
Fix Released
Bug description:
ListItem/Empty.qml defines this property:
default property alias children: body.children
Empty is inherited by Base, and basically means that for all ListItems the
default property is "children". This comes a bit as a surprise to a QtQuick
developer, because the default property for Item is "data", and not "children".
This fact has the unfortunate effect that it's not possible to freely declare
non-graphical objects inside a ListItem. For example:
=========
ListItem.Standard {
property variant accountServiceHandle
text: accountService.service.id
icon: "image://gicon/" + accountService.service.iconName
AccountService {
id: accountService
objectHandle: accountServiceHandle
}
}
=========
The above snippet will not work (the QML engine will complain "Cannot assign
object to list"), because the AccountService is not a QQuickItem, and the
ListItem is trying to assign it to the "children" property.
In order to workaround this the developer can do:
resources: AccountService {...}
but this is rather annoying, especially if the resources are more than
one.
I'd propose to double-check if the "default" keyword in the property
definition in Empty.qml file is really necessary, and remove it if it
isn't.
