Provided Methods

fn query_data(&self, lines: &GutterLines, line: u32)

fn begin(&self, lines: &GutterLines)

fn end(&self)

fn change_buffer(&self, old_buffer: Option<&Buffer>)

This is called when the text buffer changes for @self.

old_buffer

the old #GtkTextBuffer.

fn change_view(&self, old_view: Option<&View>)

This is called when the text view changes for @self.

old_view

the old #GtkTextView.

fn query_activatable(&self, iter: &TextIter, area: &Rectangle) -> bool

Get whether the renderer is activatable at the location provided. This is called from Gutter to determine whether a renderer is activatable using the mouse pointer.

iter

a #GtkTextIter at the start of the line to be activated

area

a #GdkRectangle of the cell area to be activated

Returns

true if the renderer can be activated, false otherwise

fn activate( &self, iter: &TextIter, area: &Rectangle, button: u32, state: ModifierType, n_presses: i32, )

Emits the activate signal of the renderer. This is called from Gutter and should never have to be called manually.

iter

a #GtkTextIter at the start of the line where the renderer is activated

area

a #GdkRectangle of the cell area where the renderer is activated

button

the button that was pressed

state

a #GdkModifierType

n_presses

the number of button presses

fn snapshot_line(&self, snapshot: &Snapshot, lines: &GutterLines, line: u32)
