GI.Gtk.Objects.EntryCompletion

EntryCompletion is an auxiliary object to be used in conjunction with Entry to provide the completion functionality. It implements the CellLayout interface, to allow the user to add extra cells to the TreeView with completion matches.

“Completion functionality” means that when the user modifies the text in the entry, EntryCompletion checks which rows in the model match the current content of the entry, and displays a list of matches. By default, the matching is done by comparing the entry text case-insensitively against the text column of the model (see entryCompletionSetTextColumn), but this can be overridden with a custom match function (see entryCompletionSetMatchFunc).

When the user selects a completion, the content of the entry is updated. By default, the content of the entry is replaced by the text column of the model, but this can be overridden by connecting to the EntryCompletion::match-selected signal and updating the entry in the signal handler. Note that you should return True from the signal handler to suppress the default behaviour.

To add completion functionality to an entry, use entrySetCompletion.

In addition to regular completion matches, which will be inserted into the entry when they are selected, EntryCompletion also allows to display “actions” in the popup window. Their appearance is similar to menuitems, to differentiate them clearly from completion strings. When an action is selected, the EntryCompletion::action-activated signal is emitted.

GtkEntryCompletion uses a TreeModelFilter model to represent the subset of the entire model that is currently matching. While the GtkEntryCompletion signals EntryCompletion::match-selected and EntryCompletion::cursor-on-match take the original model and an iter pointing to that model as arguments, other callbacks and signals (such as GtkCellLayoutDataFuncs or CellArea::apply-attributes) will generally take the filter model as argument. As long as you are only calling gtk_tree_model_get(), this will make no difference to you. If for some reason, you need the original model, use treeModelFilterGetModel. Don’t forget to use treeModelFilterConvertIterToChildIter to obtain a matching iter.
