Provided Methods

fn backspace(&self)

The class handler for the GtkTextView::backspace keybinding signal.

fn copy_clipboard(&self)

The class handler for the GtkTextView::copy-clipboard keybinding signal.

fn cut_clipboard(&self)

The class handler for the GtkTextView::cut-clipboard keybinding signal

fn delete_from_cursor(&self, type_: DeleteType, count: i32)

The class handler for the GtkTextView::delete-from-cursor keybinding signal.

fn extend_selection( &self, granularity: TextExtendSelection, location: &TextIter, start: &mut TextIter, end: &mut TextIter ) -> ControlFlow

The class handler for the GtkTextView::extend-selection signal.

fn insert_at_cursor(&self, text: &str)

The class handler for the GtkTextView::insert-at-cursor keybinding signal.

fn insert_emoji(&self)

The class handler for the GtkTextView::insert-emoji signal.

fn move_cursor(&self, step: MovementStep, count: i32, extend_selection: bool)

The class handler for the GtkTextView::move-cursor keybinding signal.

fn paste_clipboard(&self)

The class handler for the GtkTextView::paste-clipboard keybinding signal.

fn set_anchor(&self)

The class handler for the GtkTextView::set-anchor keybinding signal.

fn snapshot_layer(&self, layer: TextViewLayer, snapshot: Snapshot)

The snapshot_layer vfunc is called before and after the text view is drawing its own text. Applications can override this vfunc in a subclass to draw customized content underneath or above the text. In the TextViewLayer::BelowText and TextViewLayer::AboveText layers the drawing is done in the buffer coordinate space.

fn toggle_overwrite(&self)

The class handler for the GtkTextView::toggle-overwrite keybinding signal.
