Struct gtk4::TreeModelFlags

pub struct TreeModelFlags { /* fields omitted */ }

These flags indicate various properties of a TreeModel.

They are returned by TreeModelExt::flags(), and must be static for the lifetime of the object. A more complete description of ITERS_PERSIST can be found in the overview of this section.

Implementations

impl TreeModelFlags

pub const ITERS_PERSIST: TreeModelFlags

iterators survive all signals emitted by the tree

Returns the set containing all flags.

pub const fn bits(&self) -> u32

Returns the raw value of the flags currently stored.

pub fn from_bits(bits: u32) -> Option<TreeModelFlags>

pub const fn from_bits_truncate(bits: u32) -> TreeModelFlags

Convert from underlying bit representation, dropping any bits that do not correspond to flags.

pub const unsafe fn from_bits_unchecked(bits: u32) -> TreeModelFlags

Convert from underlying bit representation, preserving all bits (even those not corresponding to a defined flag).

pub const fn is_empty(&self) -> bool

Returns true if no flags are currently stored.

pub const fn is_all(&self) -> bool

Returns true if all flags are currently set.

pub const fn intersects(&self, other: TreeModelFlags) -> bool

Returns true if there are flags common to both self and other.

pub const fn contains(&self, other: TreeModelFlags) -> bool

Returns true all of the flags in other are contained within self.

Removes the specified flags in-place.

pub fn toggle(&mut self, other: TreeModelFlags)

pub fn set(&mut self, other: TreeModelFlags, value: bool)

Inserts or removes the specified flags depending on the passed value.
