Add a new GtkSourceCompletionProvider to the completion object. This will add a reference `provider`, so make sure to unref your own copy when you no longer need it.

`completion` : | A GtkSourceCompletion
`provider` : | A GtkSourceCompletionProvider
`error` : | A GError
Returns : | `TRUE` if `provider` was successfully added, otherwise if `error` is provided, it will be set with the error and `FALSE` is returned.

### gtk_source_completion_remove_provider ()

    gboolean            gtk_source_completion_remove_provider

Remove `provider` from the completion.

`completion` : | A GtkSourceCompletion
`provider` : | A GtkSourceCompletionProvider
`error` : | A GError
Returns : | `TRUE` if `provider` was successfully removed, otherwise if `error` is provided, it will be set with the error and `FALSE` is returned.

### gtk_source_completion_get_providers ()

    GList *             gtk_source_completion_get_providers (GtkSourceCompletion *completion);

Get list of providers registered on `completion`. The returned list is owned by the completion and should not be freed.

`completion` : | The GtkSourceCompletion
Returns : | list of GtkSourceCompletionProvider

### gtk_source_completion_show ()

    gboolean            gtk_source_completion_show          (GtkSourceCompletion *completion,
                                                             GList *providers,
                                                             GtkSourceCompletionContext *context);

Starts a new completion with the specified GtkSourceCompletionContext and a list of potential candidate providers for completion.

`completion` : | A GtkSourceCompletion
`providers` : | A list of GtkSourceCompletionProvider or `NULL`
`context` : | The GtkSourceCompletionContext with which to start the completion
Returns : | `TRUE` if it was possible to the show completion window.

### gtk_source_completion_hide ()

    void                gtk_source_completion_hide          (GtkSourceCompletion *completion);

Hides the completion if it is active (visible).

`completion` : | A GtkSourceCompletion

### gtk_source_completion_get_info_window ()

    GtkSourceCompletionInfo * gtk_source_completion_get_info_window
                                                            (GtkSourceCompletion *completion);

The info widget is the window where the completion displays optional extra information of the proposal.

`completion` : | A GtkSourceCompletion
Returns : | The GtkSourceCompletionInfo window.

### gtk_source_completion_get_view ()

    struct _GtkSourceView * gtk_source_completion_get_view  (GtkSourceCompletion *completion);

The GtkSourceView associated with `completion`.

`completion` : | A GtkSourceCompletion
Returns : | The GtkSourceView associated with `completion`.

### gtk_source_completion_create_context ()

    GtkSourceCompletionContext * gtk_source_completion_create_context
                                                            (GtkSourceCompletion *completion,

Create a new GtkSourceCompletionContext for `completion`. The position at which the completion using the new context will consider completion can be provider by `position`. If `position` is `NULL`, the current cursor position will be used.

`completion` : | A GtkSourceCompletion
`position` : | A GtkTextIter
Returns : | a new GtkSourceCompletionContext. The reference being returned is a 'floating' reference, so if you invoke gtk_source_completion_show with this context you don't need to unref it.

### gtk_source_completion_move_window ()

    void                gtk_source_completion_move_window   (GtkSourceCompletion *completion,
                                                             GtkTextIter *iter);

Block interactive completion. This can be used to disable interactive completion when inserting or deleting text from the buffer associated with the completion. Use gtk_source_completion_unblock_interactive to enable interactive completion again.

`completion` : | A # GtkSourceCompletion

### gtk_source_completion_unblock_interactive ()

    void                gtk_source_completion_unblock_interactive
                                                            (GtkSourceCompletion *completion);

The ::activate-proposal signal is a keybinding signal which gets emitted when the user initiates a proposal activation.

Applications should not connect to it, but may emit it with g_signal_emit_by_name if they need to control the proposal activation programmatically.

`completion` : | The GtkSourceCompletion who emits the signal
`user_data` : | user data set when the signal handler was connected.

### The `"hide"` signal

`completion` : | The GtkSourceCompletion who emits the signal
`user_data` : | user data set when the signal handler was connected.

### The `"move-cursor"` signal

    void                user_function                      (GtkSourceCompletion *completion,
                                                            GtkScrollStep        step,

The ::move-cursor signal is a keybinding signal which gets emitted when the user initiates a cursor movement.

Applications should not connect to it, but may emit it with g_signal_emit_by_name if they need to control the cursor programmatically.

`completion` : | The GtkSourceCompletion who emits the signal
`step` : | The GtkScrollStep by which to move the cursor
`num` : | The amount of steps to move the cursor
`user_data` : | user data set when the signal handler was connected.

The ::move-page signal is a keybinding signal which gets emitted when the user initiates a page movement (i.e. switches between provider pages).

Applications should not connect to it, but may emit it with g_signal_emit_by_name if they need to control the page selection programmatically.

`user_data` : | user data set when the signal handler was connected.

### The `"show"` signal
