<!-- ##### SECTION Title ##### -->GtkEntryCompletion<!-- ##### SECTION Short_Description ##### -->Completion functionality for GtkEntry<!-- ##### SECTION Long_Description ##### --><para>#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. </para><para>"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_set_text_column()), but this can be overridden with a custom match function (see gtk_entry_completion_set_match_func()).</para><para>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 signaland updating the entry in the signal handler. Note that you should return %TRUE from the signal handler to suppress the default behaviour.</para><para>To add completion functionality to an entry, use gtk_entry_set_completion().</para><para>In addition to regular completion matches, which will be inserted into theentry 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 ::action-activated signal is emitted.</para><!-- ##### SECTION See_Also ##### --><para></para><!-- ##### SECTION Stability_Level ##### --><!-- ##### STRUCT GtkEntryCompletion ##### --><para>The GtkEntryCompletion struct contains only private data.</para><!-- ##### SIGNAL GtkEntryCompletion::action-activated ##### --><para></para>@entrycompletion: the object which received the signal.@arg1: <!-- ##### SIGNAL GtkEntryCompletion::insert-prefix ##### --><para></para>@entrycompletion: the object which received the signal.@arg1: @Returns: <!-- ##### SIGNAL GtkEntryCompletion::match-selected ##### --><para></para>@entrycompletion: the object which received the signal.@arg1: @arg2: @Returns: <!-- ##### ARG GtkEntryCompletion:inline-completion ##### --><para></para><!-- ##### ARG GtkEntryCompletion:minimum-key-length ##### --><para></para><!-- ##### ARG GtkEntryCompletion:model ##### --><para></para><!-- ##### ARG GtkEntryCompletion:popup-completion ##### --><para></para><!-- ##### ARG GtkEntryCompletion:text-column ##### --><para></para><!-- ##### USER_FUNCTION GtkEntryCompletionMatchFunc ##### --><para>A function which decides whether the row indicated by @iter matches a given @key, and should be displayed as a possible completion for @key.
