I am trying to understand how Kodi components are initialized and I am stuck with a problem to trace how the items list in containers is created.

I believe the items are stored in the CGUIBaseContainer property:

Code:

std::vector< CGUIListItemPtr > m_items;

but I fail to understand how is this list is populated when the component is created? For a moment I thought it was done through the UpdateListProvider() function, which is apparently not systematically invoked...

anyone could point me to the right direction?

Thank you in advance,
Pierre

ok, it took me a while and it seems obvious now, but if anyone else get lost in code as I did, here is the call stack leading to the container's list being populated (for the media window, others probably use a similar mechanism):

CGUIMediaWindow::Update() : Scans the db for content, builds m_vecItems with the result of the query, then calls:
CGUIMediaWindow::OnFilterItems() : Filter and sorts the content then calls:
CGUIViewControl::SetItems(): calls :
CGUIViewControl::UpdateView(): calls :
CGUIViewControl::UpdateContents(): broadcasts a message GUI_MSG_LABEL_BIND
CGUIBaseContainer::OnMessage(): will process the message, and copy the items list into the CGUIBaseContainer::m_items property
