Implementations

impl TreePath

pub fn as_ptr(&self) -> *mut GtkTreePath

Return the inner pointer to the underlying C value.

pub unsafe fn from_glib_ptr_borrow<'a>( ptr: *const *const GtkTreePath ) -> &'a Self

Borrows the underlying C value.

pub unsafe fn from_glib_ptr_borrow_mut<'a>( ptr: *mut *mut GtkTreePath ) -> &'a mut Self

Borrows the underlying C value mutably.

impl TreePath

pub fn new() -> TreePath

👎Deprecated: Since 4.10

Creates a new TreePath This refers to a row.

Deprecated since 4.10

Returns

A newly created TreePath.

pub fn new_first() -> TreePath

👎Deprecated: Since 4.10

Creates a new TreePath.

The string representation of this path is “0”.

Deprecated since 4.10

Returns

A new TreePath

pub fn from_indices(indices: &[i32]) -> TreePath

👎Deprecated: Since 4.10

Creates a new path with the given @indices array of @length.

Deprecated since 4.10

indices

array of indices

Returns

A newly created TreePath

pub fn from_string(path: &str) -> Option<TreePath>

👎Deprecated: Since 4.10

Creates a new TreePath initialized to @path.

@path is expected to be a colon separated list of numbers. For example, the string “10:4:0” would create a path of depth 3 pointing to the 11th child of the root node, the 5th child of that 11th child, and the 1st child of that 5th child. If an invalid path string is passed in, None is returned.

Deprecated since 4.10

path

The string representation of a path

Returns

A newly-created TreePath

pub fn append_index(&mut self, index_: i32)

👎Deprecated: Since 4.10

Appends a new index to a path.

As a result, the depth of the path is increased.

Deprecated since 4.10

index_

the index

pub fn down(&mut self)

👎Deprecated: Since 4.10

Moves @self to point to the first child of the current path.

Deprecated since 4.10

pub fn depth(&self) -> i32

👎Deprecated: Since 4.10

Returns the current depth of @self.

Deprecated since 4.10

Returns

The depth of @self

pub fn is_ancestor(&self, descendant: &TreePath) -> bool

👎Deprecated: Since 4.10

Returns true if @descendant is a descendant of @self.

Deprecated since 4.10

descendant

another TreePath

Returns

true if @descendant is contained inside @self

pub fn is_descendant(&self, ancestor: &TreePath) -> bool

👎Deprecated: Since 4.10

Returns true if @self is a descendant of @ancestor.

Deprecated since 4.10

ancestor

another TreePath

Returns

true if @ancestor contains @self somewhere below it

pub fn next(&mut self)

👎Deprecated: Since 4.10

Moves the @self to point to the next node at the current depth.

Deprecated since 4.10

pub fn prepend_index(&mut self, index_: i32)

👎Deprecated: Since 4.10

Prepends a new index to a path.

As a result, the depth of the path is increased.

Deprecated since 4.10

index_

the index

pub fn prev(&mut self) -> bool

👎Deprecated: Since 4.10

Moves the @self to point to the previous node at the current depth, if it exists.

Deprecated since 4.10

Returns

true if @self has a previous node, and the move was made

pub fn to_str(&self) -> Option<GString>

👎Deprecated: Since 4.10

Generates a string representation of the path.

This string is a “:” separated list of numbers. For example, “4:10:0:3” would be an acceptable return value for this string. If the path has depth 0, None is returned.

Deprecated since 4.10

Returns

A newly-allocated string

pub fn up(&mut self) -> bool

👎Deprecated: Since 4.10

Moves the @self to point to its parent node, if it has a parent.

Deprecated since 4.10

Returns

true if @self has a parent, and the move was made

impl TreePath

pub fn indices(&self) -> Slice<i32>

👎Deprecated: Since 4.10

Returns the current indices of @self.

This is an array of integers, each representing a node in a tree. It also returns the number of elements in the array. The array should not be freed.

Deprecated since 4.10

Returns

The current indices
