Enum gtk4::TreeViewDropPosition

#[non_exhaustive]
pub enum TreeViewDropPosition {
    Before,
    After,
    IntoOrBefore,
    IntoOrAfter,
}

An enum for determining where a dropped row goes.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Before

dropped row is inserted before

After

dropped row is inserted after

IntoOrBefore

dropped row becomes a child or is inserted before

IntoOrAfter

dropped row becomes a child or is inserted after

impl Ord for TreeViewDropPosition

fn cmp(&self, other: &TreeViewDropPosition) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

impl PartialEq for TreeViewDropPosition

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.
