Module for [EntryCompletion] class

class EntryCompletion EntryCompletionGidBuilder EntryCompletionGidBuilderImpl

Types 3

classEntryCompletion : gobject.object.ObjectWrap, gtk.buildable.Buildable, gtk.cell_layout.CellLayout

#GtkEntryCompletion is an auxiliary object to be used in conjunction with #GtkEntry to provide the completion functionality. It implements the #GtkCellLayout interface, to allow the user to add extra cells to the #GtkTreeView with completion matches.

“Completion functionality” means that when the user modifies the text in the entry, #GtkEntryCompletion 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 gtk.entry_completion.EntryCompletion.setTextColumn), but this can be overridden with a custom match function (see gtk.entry_completion.EntryCompletion.setMatchFunc).

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 #GtkEntryCompletion::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 gtk.entry.Entry.setCompletion.

In addition to regular completion matches, which will be inserted into the entry when they are selected, #GtkEntryCompletion 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 #GtkEntryCompletion::action-activated signal is emitted.

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