Gutter

Provided Methods

fn renderer_at_pos(&self, x: i32, y: i32) -> Option<GutterRenderer>

Finds the GutterRenderer at (x, y).

x

The x position to get identified.

y

The y position to get identified.

Returns

the renderer at (x, y) or None.

fn view(&self) -> Option<View>

Returns

the associated View.

fn window_type(&self) -> TextWindowType

Returns

the gtk::TextWindowType of self.

fn insert(&self, renderer: &impl IsA<GutterRenderer>, position: i32) -> bool

Insert renderer into the gutter. If renderer is yet unowned then gutter claims its ownership. Otherwise just increases renderer’s reference count. renderer cannot be already inserted to another gutter.

renderer

a gutter renderer (must inherit from GutterRenderer).

position

the renderer position.

Returns

true if operation succeeded. Otherwise false.

fn queue_draw(&self)

Invalidates the drawable area of the gutter. You can use this to force a redraw of the gutter if something has changed and needs to be redrawn.

fn remove(&self, renderer: &impl IsA<GutterRenderer>)

Removes renderer from self.

renderer

a GutterRenderer.

fn reorder(&self, renderer: &impl IsA<GutterRenderer>, position: i32)

Reorders renderer in self to new position.

renderer

a GtkCellRenderer.

position

the new renderer position.
