Enum gtk::WindowPosition

#[non_exhaustive]
pub enum WindowPosition {
    None,
    Center,
    Mouse,
    CenterAlways,
    CenterOnParent,
    // some variants omitted
}

Window placement can be influenced using this enumeration. Note that using CenterAlways is almost always a bad idea. It won’t necessarily work well with all window managers or on all windowing systems.

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.

None

No influence is made on placement.

Center

Windows should be placed in the center of the screen.

Mouse

Windows should be placed at the current mouse position.

CenterAlways

Keep window centered as it changes size, etc.

CenterOnParent

Center the window on its transient parent (see GtkWindowExt::set_transient_for()).

Trait Implementations

fn clone(&self) -> WindowPosition

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for WindowPosition

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

Formats the value using the given formatter.

impl Display for WindowPosition

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

Formats the value using the given formatter.

impl<'a> FromValue<'a> for WindowPosition

type Checker = GenericValueTypeChecker<WindowPosition>

Value type checker.

unsafe fn from_value(value: &'a Value) -> Self

Get the contained value from a Value.

impl Hash for WindowPosition

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where
    H: Hasher,

Feeds a slice of this type into the given Hasher.

impl Ord for WindowPosition

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

const fn clamp(self, min: Self, max: Self) -> Selfwhere
    Self: PartialOrd<Self>,

impl PartialEq<WindowPosition> for WindowPosition

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

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

const 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 less than (for self and other) and is used by the < operator.

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

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

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

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

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