Trait containing all TextMark methods.

§Implementors

TextMark

Provided Methods§

Source

fn buffer(&self) -> Option<TextBuffer>

Gets the buffer this mark is located inside.

Returns None if the mark is deleted.

§Returns

the mark’s TextBuffer

Source

fn is_deleted(&self) -> bool

Returns true if the mark has been removed from its buffer.

See TextBufferExt::add_mark() for a way to add it to a buffer again.

§Returns

whether the mark is deleted

Source

fn is_left_gravity(&self) -> bool

Determines whether the mark has left gravity.

§Returns

true if the mark has left gravity, false otherwise

Source

fn name(&self) -> Option<GString>

Returns the mark name.

Returns None for anonymous marks.

§Returns

mark name

Source

fn is_visible(&self) -> bool

Returns true if the mark is visible.

A cursor is displayed for visible marks.

§Returns

true if visible

Source

fn set_visible(&self, setting: bool)

Sets the visibility of @self.

The insertion point is normally visible, i.e. you can see it as a vertical bar. Also, the text widget uses a visible mark to indicate where a drop will occur when dragging-and-dropping text. Most other marks are not visible.

Marks are not visible by default.

§setting

visibility of mark

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
