Struct QModelIndex

#[repr(C)]
pub struct QModelIndex { /* private fields */ }

The QModelIndex class is used to locate data in a data model.

Implementations

impl QModelIndex

pub fn column(&self) -> i32

Returns the column this model index refers to.

impl QModelIndex

pub fn is_valid(&self) -> bool

Returns true if this model index is valid; otherwise returns false.

A valid index belongs to a model, and has non-negative row and column numbers.

impl QModelIndex

pub fn parent(&self) -> QModelIndex

Returns the parent of the model index, or QModelIndex() if it has no parent.

impl QModelIndex

pub fn row(&self) -> i32

Returns the row this model index refers to.

impl QModelIndex

pub fn sibling(&self, row: i32, column: i32) -> QModelIndex

Returns the sibling at row and column. If there is no sibling at this position, an invalid QModelIndex is returned.

impl QModelIndex

pub fn sibling_at_column(&self, column: i32) -> QModelIndex

Returns the sibling at column for the current row. If there is no sibling at this position, an invalid QModelIndex is returned.

impl QModelIndex

pub fn sibling_at_row(&self, row: i32) -> QModelIndex

Returns the sibling at row for the current column. If there is no sibling at this position, an invalid QModelIndex is returned.

impl QModelIndex

pub fn internal_pointer_mut(&self) -> *mut c_void

Returns a *mut c_void pointer used by the model to associate the index with the internal data structure.

impl QModelIndex

pub fn internal_id(&self) -> usize

Returns a usize used by the model to associate the index with the internal data structure.

Trait Implementations

impl Clone for QModelIndex

fn clone(&self) -> QModelIndex

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for QModelIndex

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for QModelIndex

fn default() -> Self

Creates a new empty model index. This type of model index is used to indicate that the position in the model is invalid.

impl Display for QModelIndex

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl ExternType for QModelIndex

type Id = (Q, M, o, d, e, l, I, n, d, e, x)

A type-level representation of the type’s C++ namespace and type name.

type Kind = Trivial

Either cxx::kind::Opaque or cxx::kind::Trivial.

impl From<&QModelIndex> for QPersistentModelIndex

fn from(index: &QModelIndex) -> Self

Creates a new QPersistentModelIndex that is a copy of the model index.

impl PartialEq for QModelIndex

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl QVariantValue for QModelIndex

fn can_convert(variant: &QVariant) -> bool

fn construct(value: &Self) -> QVariant

fn value_or_default(variant: &QVariant) -> Self

impl Eq for QModelIndex
