Class Details

class GtkSource.Completion(**kwargs)
Bases:GObject.Object, Gtk.Buildable
Abstract:No
Structure:GtkSource.CompletionClass
add_provider(provider)
Parameters:provider (GtkSource.CompletionProvider) – a GtkSource.CompletionProvider.
Raises:GLib.Error
Returns:True if provider was successfully added, otherwise if error is provided, it will be set with the error and False is returned.
Return type:bool

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

block_interactive()

Block interactive completion. This can be used to disable interactive completion when inserting or deleting text from the buffer associated with the completion. Use GtkSource.Completion.unblock_interactive() to enable interactive completion again.

This function may be called multiple times. It will continue to block interactive completion until GtkSource.Completion.unblock_interactive() has been called the same number of times.

create_context(position)
Parameters:position (Gtk.TextIter or None) – a Gtk.TextIter, or None.
Returns:a new GtkSource.CompletionContext. The reference being returned is a ‘floating’ reference, so if you invoke GtkSource.Completion.show() with this context you don’t need to unref it.
Return type:GtkSource.CompletionContext

Create a new GtkSource.CompletionContext for self. The position where the completion occurs can be specified by position. If position is None, the current cursor position will be used.

get_info_window()
Returns:The GtkSource.CompletionInfo window associated with self.
Return type:GtkSource.CompletionInfo

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

get_providers()
Returns:list of GtkSource.CompletionProvider.
Return type:[GtkSource.CompletionProvider]

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

get_view()
Returns:The GtkSource.View associated with self, or None.
Return type:GtkSource.View or None

The GtkSource.View associated with self, or None if the view has been destroyed.

hide()

Hides the completion if it is active (visible).

move_window(iter)
Parameters:iter (Gtk.TextIter) – a Gtk.TextIter.

Move the completion window to a specific iter.

Deprecated since version 3.8: Use GtkSource.CompletionProvider.get_start_iter() instead.

remove_provider(provider)
Parameters:provider (GtkSource.CompletionProvider) – a GtkSource.CompletionProvider.
Raises:GLib.Error
Returns:True if provider was successfully removed, otherwise if error is provided, it will be set with the error and False is returned.
Return type:bool

Remove provider from the completion.

show(providers, context)
Parameters:
Returns:

True if it was possible to the show completion window.

Return type:

bool

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

It can be convenient for showing a completion on-the-fly, without the need to add or remove providers to the GtkSource.Completion.

Another solution is to add providers with GtkSource.Completion.add_provider(), and implement GtkSource.CompletionProvider.match() for each provider.

unblock_interactive()

Unblock interactive completion. This can be used after using GtkSource.Completion.block_interactive() to enable interactive completion again.

do_activate_proposal() virtual
do_hide() virtual

Hides the completion if it is active (visible).

do_move_cursor(step, num) virtual
Parameters:
do_move_page(step, num) virtual
Parameters:
do_populate_context(context) virtual
Parameters:context (GtkSource.CompletionContext) –
do_proposal_activated(provider, proposal) virtual
Parameters:
Return type:

bool

do_show() virtual

Signal Details

GtkSource.Completion.signals.activate_proposal(completion)
Signal Name:activate-proposal
Flags:RUN_LAST, ACTION
Parameters:completion (GtkSource.Completion) – The object which received the signal

The GtkSource.Completion ::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.

GtkSource.Completion.signals.hide(completion)
Signal Name:hide
Flags:RUN_LAST, ACTION
Parameters:completion (GtkSource.Completion) – The object which received the signal

Emitted when the completion window is hidden. The default handler will actually hide the window.

GtkSource.Completion.signals.move_cursor(completion, step, num)
Signal Name:

move-cursor

Flags:

RUN_LAST, ACTION

Parameters:

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

The Up, Down,

PageUp, PageDown, Home and End keys are bound to the normal behavior expected by those keys.

When step is equal to Gtk.ScrollStep.PAGES, the page size is defined by the GtkSource.Completion :proposal-page-size property. It is used for the PageDown and PageUp keys.

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

GtkSource.Completion.signals.move_page(completion, step, num)
Signal Name:

move-page

Flags:

RUN_LAST, ACTION

Parameters:

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

Control + Left is for going to the previous provider.

Control + Right is for going to the next provider.

Control + Home is for displaying all the providers.

Control + End is for going to the last provider.

When step is equal to Gtk.ScrollStep.PAGES, the page size is defined by the GtkSource.Completion :provider-page-size property.

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.

GtkSource.Completion.signals.populate_context(completion, context)
Signal Name:

populate-context

Flags:

RUN_LAST, ACTION

Parameters:

Emitted just before starting to populate the completion with providers. You can use this signal to add additional attributes in the context.

GtkSource.Completion.signals.show(completion)
Signal Name:show
Flags:RUN_LAST, ACTION
Parameters:completion (GtkSource.Completion) – The object which received the signal

Emitted when the completion window is shown. The default handler will actually show the window.

Property Details

GtkSource.Completion.props.accelerators
Name:accelerators
Type:int
Default Value:5
Flags:READABLE, WRITABLE, CONSTRUCT

Number of keyboard accelerators to show for the first proposals. For example, to activate the first proposal, the user can press

Alt + 1.

GtkSource.Completion.props.auto_complete_delay
Name:auto-complete-delay

Default Value:250
Flags:READABLE, WRITABLE, CONSTRUCT

GtkSource.Completion.props.proposal_page_size
Name:proposal-page-size
Type:int
Default Value:5

The scroll page size of the proposals in the completion window. In other words, when PageDown or

PageUp is pressed, the selected proposal becomes the one which is located one page size backward or forward.
