A list model that sorts its items.
Gtk::SortListModel is a list model that takes a list model and sorts its elements according to a Gtk::Sorter.
The model can be set up to do incremental sorting, so that sorting long lists doesn't block the UI. See set_incremental() for details.
Gtk::SortListModel is a generic model and because of that it cannot take advantage of any external knowledge when sorting. If you run into performance issues with Gtk::SortListModel, it is strongly recommended that you write your own sorting list model.
- See also
- Gio::ListModel, Gtk::Sorter
- Since gtkmm 3.98:
void Gtk::SortListModel::set_incremental |
( |
bool |
incremental = true | ) |
|
Sets the sort model to do an incremental sort.
When incremental sorting is enabled, the Gtk::SortListModel
will not do a complete sort immediately, but will instead queue an idle handler that incrementally sorts the items towards their correct position. This of course means that items do not instantly appear in the right place. It also means that the total sorting time is a lot slower.
When your filter blocks the UI while sorting, you might consider turning this on. Depending on your model and sorters, this may become interesting around 10,000 to 100,000 items.
By default, incremental sorting is disabled.
See get_pending() for progress information about an ongoing incremental sorting operation.

-
incremental | true to sort incrementally. |
