Detailed Description

Completion functionality for Gtk::Entry.

Gtk::EntryCompletion is an auxiliary object to be used in conjunction with Gtk::Entry to provide the completion functionality.

It derives from Gtk::CellLayout, to allow the user to add extra cells to the Gtk::TreeView with completion matches.

"Completion functionality" means that when the user modifies the text in the entry, Gtk::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 set_text_column()), but this can be overridden with a custom match function (see 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 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::set_completion().

length

The minimum length of the key in order to start completing.

void Gtk::EntryCompletion::set_model

(

const Glib::RefPtr< TreeModel >&

model

)

Sets the model for a Gtk::EntryCompletion.

Since gtkmm 2.4:

Parameters

model

The Gtk::TreeModel.

void Gtk::EntryCompletion::set_popup_completion

(

bool

popup_completion = true

)

Sets whether the completions should be presented in a popup window.

bool

popup_set_width = true

Sets whether the completion popup window will be resized to be the same width as the entry.

Parameters

popup_set_width

true to make the width of the popup the same as the entry.

void Gtk::EntryCompletion::set_popup_single_match

(

bool

popup_single_match = true

)

Sets whether the completion popup window will appear even if there is only a single match.

You may want to set this to false if you are using [inline completion][GtkEntryCompletion–inline-completion].

Parameters

popup_single_match

true if the popup should appear even for a single match.

void Gtk::EntryCompletion::set_text_column

(

const TreeModelColumnBase&

column

)

Convenience function for setting up the most used case of this code: a completion list with just strings.

This function will set up completion to have a list displaying all (and just) strings in the completion list, and to get those strings from column in the model of completion.

This functions creates and adds a Gtk::CellRendererText for the selected column. If you need to set the text column, but don't want the cell renderer, use Glib::object_set() to set the Gtk::EntryCompletion::property_text_column() property directly.

Parameters

column

The column in the model of completion to get strings from.

void Gtk::EntryCompletion::set_text_column

int

Glib::SignalProxy<bool(const TreeModel::iterator&)> Gtk::EntryCompletion::signal_cursor_on_match

(

)

Emitted when a match from the cursor is on a match of the list.

The default behaviour is to replace the contents of the entry with the contents of the text column in the row pointed to by iter.

Parameters

model	The TreeModel containing the matches
iter	A TreeModel::iterator positioned at the selected match

Returns

true if the signal has been handled

Prototype:

bool on_cursor_on_match(const TreeModel::iterator& iter)

Since gtkmm 2.12:

Glib::SignalProxy<bool(const Glib::ustring&)> Gtk::EntryCompletion::signal_insert_prefix

(

)

Slot Prototype:

bool on_my_insert_prefix(const Glib::ustring& prefix)

Flags: Run Last

Gets emitted when the inline autocompletion is triggered. The default behaviour is to make the entry display the whole prefix and select the newly inserted part.

Applications may connect to this signal in order to insert only a smaller part of the prefix into the entry - e.g. the entry used in the Gtk::FileChooser inserts only the part of the prefix up to the next '/'.

Parameters

prefix

The common prefix of all possible completions.

Returns

true if the signal has been handled.

Glib::SignalProxy<bool(const TreeModel::iterator&)> Gtk::EntryCompletion::signal_match_selected

(

)

Emitted when a match from the list is selected.

The default behaviour is to replace the contents of the entry with the contents of the text column in the row pointed to by iter.

It is necessary to connect your signal handler before the default one, which would otherwise return true, a value which signifies that the signal has been handled, thus preventing any other handler from being invoked.

To do this, pass false to this signal proxy's connect() method. For example: completion->signal_match_selected().connect(sigc::mem_fun(* this,& YourClass::on_completion_match_selected), false);

Parameters

model	The TreeModel containing the matches
iter	A TreeModel::iterator positioned at the selected match

Returns

true if the signal has been handled

Prototype:

bool on_match_selected(const TreeModel::iterator& iter)

Glib::SignalProxy<void()> Gtk::EntryCompletion::signal_no_matches

(

)

Slot Prototype:

void on_my_no_matches()

Flags: Run Last

Gets emitted when the filter model has zero number of rows in completion_complete method. (In other words when GtkEntryCompletion is out of suggestions)

void Gtk::EntryCompletion::unset_model

(

)

Remove the model from the EntryCompletion.
