EntryCompletionRef
public struct EntryCompletionRef : EntryCompletionProtocol, GWeakCapturing
GtkEntryCompletion
is an auxiliary object to provide completion functionality
for GtkEntry
.
It implements the [ifaceGtk.CellLayout
] 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
[methodGtk.EntryCompletion.set_text_column
]), but this can be overridden
with a custom match function (see [methodGtk.EntryCompletion.set_match_func
]).
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 [signalGtk.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
[methodGtk.Entry.set_completion
].
GtkEntryCompletion
uses a [classGtk.TreeModelFilter
] model to
represent the subset of the entire model that is currently matching.
While the GtkEntryCompletion
signals
[signalGtk.EntryCompletion::match-selected
] and
[signalGtk.EntryCompletion::cursor-on-match
] take the original model
and an iter pointing to that model as arguments, other callbacks and
signals (such as GtkCellLayoutDataFunc
or
[signalGtk.CellArea::apply-attributes
)]
will generally take the filter model as argument. As long as you are
only calling [methodGtk.TreeModel.get
], this will make no difference to
you. If for some reason, you need the original model, use
[methodGtk.TreeModelFilter.get_model
]. Don’t forget to use
[methodGtk.TreeModelFilter.convert_iter_to_child_iter
] to obtain a
matching iter.
The EntryCompletionRef
type acts as a lightweight Swift reference to an underlying GtkEntryCompletion
instance.
It exposes methods that can operate on this data type through EntryCompletionProtocol
conformance.
Use EntryCompletionRef
only as an unowned
reference to an existing GtkEntryCompletion
instance.
