Struct qt_core::q_abstract_item_model::CheckIndexOption

pub struct CheckIndexOption(/* private fields */);

This enum can be used to control the checks performed by QAbstractItemModel::checkIndex().

C++ enum: QAbstractItemModel::CheckIndexOption.

C++ documentation:

This enum can be used to control the checks performed by QAbstractItemModel::checkIndex().

This enum was introduced or modified in Qt 5.11.

The CheckIndexOptions type is a typedef for QFlags<CheckIndexOption>. It stores an OR combination of CheckIndexOption values.

Implementations

impl CheckIndexOption

pub fn to_int(&self) -> c_int

impl CheckIndexOption

pub const NoOption: CheckIndexOption = _

No check options are specified. (C++ enum variant: NoOption = 0)

pub const IndexIsValid: CheckIndexOption = _

The model index passed to QAbstractItemModel::checkIndex() is checked to be a valid model index. (C++ enum variant: IndexIsValid = 1)

pub const DoNotUseParent: CheckIndexOption = _

Does not perform any check involving the usage of the parent of the index passed to QAbstractItemModel::checkIndex(). (C++ enum variant: DoNotUseParent = 2)

pub const ParentIsInvalid: CheckIndexOption = _

The parent of the model index passed to QAbstractItemModel::checkIndex() is checked to be an invalid model index. If both this option and DoNotUseParent are specified, then this option is ignored. (C++ enum variant: ParentIsInvalid = 4)

Trait Implementations

impl<T: Into<QFlags<CheckIndexOption>>> BitOr<T> for CheckIndexOption

type Output = QFlags<CheckIndexOption>

The resulting type after applying the | operator.

fn bitor(self, rhs: T) -> QFlags<CheckIndexOption>

Performs the | operation.

impl Clone for CheckIndexOption

fn clone(&self) -> CheckIndexOption

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CheckIndexOption

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

Formats the value using the given formatter.

impl From<CheckIndexOption> for QFlags<CheckIndexOption>

fn from(value: CheckIndexOption) -> Self

Converts to this type from the input type.

impl From<CheckIndexOption> for c_int

fn from(value: CheckIndexOption) -> Self

Converts to this type from the input type.

impl From<i32> for CheckIndexOption

fn from(value: c_int) -> Self

Converts to this type from the input type.

impl PartialEq for CheckIndexOption

fn eq(&self, other: &CheckIndexOption) -> 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.
