Tree model for the portfolio/book hierarchy.
The top-level item is always the owning party node. Real portfolios are inner nodes and books are leaves. Virtual portfolios (is_virtual == 1) are included as structural parents distinguished by the outline Briefcase icon.
Member Function Documentation
◆ load()
| void load | ( | const QString & | party_name, |
| std::vector< refdata::domain::portfolio > | portfolios, | ||
| std::vector< refdata::domain::book > | books | ||
| ) |
Rebuild the tree from raw portfolio and book data.
Creates a single party root node named party_name, then adds portfolios and books beneath it. Books are placed as leaves under their parent_portfolio_id.
◆ selected_filter()
| TreeNodeFilter selected_filter | ( | const QModelIndex & | index | ) | const |
Returns the filter for the selected index.
For a book node: sets book_id. For a portfolio node: sets portfolio_id. For a party node: returns nullopt pair (show all trades). Returns nullopt pair if index is invalid.
◆ set_trade_count()
| void set_trade_count | ( | const boost::uuids::uuid & | book_id, |
| std::uint32_t | count | ||
| ) |
Update the trade count for a book and refresh its display.
Called after background count fetches complete. Stores the count and emits dataChanged so the book label updates to show "(N)".
