Struct cxx_qt_lib::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.

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<QModelIndex> for QModelIndex

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

This method tests for self and other values to be equal, and is used by ==.

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

This method 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
