                                gpointer user_data);

gtk_entry_completion_new ()

GtkEntryCompletion *
gtk_entry_completion_new (void);

Creates a new GtkEntryCompletion object.

Returns

A newly created GtkEntryCompletion object.

                                GtkTreeModel *model);

Sets the model for a GtkEntryCompletion. If completion already has a model set, it will remove it before setting the new model. If model is NULL, then it will unset the model.

Signal Details

The “action-activated” signal

void
user_function (GtkEntryCompletion *widget,
               int                 index,
               gpointer            user_data)

Gets emitted when an action is activated.

Parameters

widget

the object which received the signal

 

index

the index of the activated action

 

user_data

user data set when the signal handler was connected.

 

Flags: Run Last

Since: 2.4


The “cursor-on-match” signal

gboolean
user_function (GtkEntryCompletion *widget,
               GtkTreeModel       *model,
               GtkTreeIter        *iter,
               gpointer            user_data)

Gets 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

widget

the object which received the signal

 

model

the GtkTreeModel containing the matches

 

iter

a GtkTreeIter positioned at the selected match

 

user_data

user data set when the signal handler was connected.

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 GtkFileChooser inserts only the part of the prefix up to the next '/'.
