Struct gdk::AnchorHints

pub struct AnchorHints { /* private fields */ }

Available on crate feature v3_22 only.

Positioning hints for aligning a window relative to a rectangle.

These hints determine how the window should be positioned in the case that the window would fall off-screen if placed in its ideal position.

For example, FLIP_X will replace Gravity::NorthWest with Gravity::NorthEast and vice versa if the window extends beyond the left or right edges of the monitor.

If SLIDE_X is set, the window can be shifted horizontally to fit on-screen. If RESIZE_X is set, the window can be shrunken horizontally to fit.

In general, when multiple flags are set, flipping should take precedence over sliding, which should take precedence over resizing.

Implementations

impl AnchorHints

pub const FLIP_X: Self = Self{bits: ffi::GDK_ANCHOR_FLIP_X as u32,}

allow flipping anchors horizontally

pub const FLIP_Y: Self = Self{bits: ffi::GDK_ANCHOR_FLIP_Y as u32,}

allow flipping anchors vertically

pub const SLIDE_X: Self = Self{bits: ffi::GDK_ANCHOR_SLIDE_X as u32,}

allow sliding window horizontally

pub const SLIDE_Y: Self = Self{bits: ffi::GDK_ANCHOR_SLIDE_Y as u32,}

allow sliding window vertically

pub const RESIZE_X: Self = Self{bits: ffi::GDK_ANCHOR_RESIZE_X as u32,}

allow resizing window horizontally

pub const RESIZE_Y: Self = Self{bits: ffi::GDK_ANCHOR_RESIZE_Y as u32,}

allow resizing window vertically

pub const FLIP: Self = Self{bits: ffi::GDK_ANCHOR_FLIP as u32,}

allow flipping anchors on both axes

pub const SLIDE: Self = Self{bits: ffi::GDK_ANCHOR_SLIDE as u32,}

allow sliding window on both axes

pub const RESIZE: Self = Self{bits: ffi::GDK_ANCHOR_RESIZE as u32,}

allow resizing window on both axes

pub const fn empty() -> Self

Returns an empty set of flags.

pub const fn all() -> Self

Returns the set containing all flags.

pub const fn bits(&self) -> u32

Returns the raw value of the flags currently stored.

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

Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.

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

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

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

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

Safety

The caller of the bitflags! macro can chose to allow or disallow extra bits for their bitflags type.

The caller of from_bits_unchecked() has to ensure that all bits correspond to a defined flag or that extra bits are valid for this bitflags type.

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: Self) -> bool

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

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

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

pub fn insert(&mut self, other: Self)

Inserts the specified flags in-place.

pub fn remove(&mut self, other: Self)

Removes the specified flags in-place.

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

Toggles the specified flags in-place.

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

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

pub const fn intersection(self, other: Self) -> Self

Returns the intersection between the flags in self and other.

Specifically, the returned set contains only the flags which are present in both self and other.

This is equivalent to using the & operator (e.g. ops::BitAnd), as in flags & other.

pub const fn union(self, other: Self) -> Self

Returns the union of between the flags in self and other.

Specifically, the returned set contains all flags which are present in either self or other, including any which are present in both (see Self::symmetric_difference if that is undesirable).

This is equivalent to using the | operator (e.g. ops::BitOr), as in flags | other.

pub const fn difference(self, other: Self) -> Self

Returns the difference between the flags in self and other.

Specifically, the returned set contains all flags present in self, except for the ones present in other.

It is also conceptually equivalent to the “bit-clear” operation: flags & !other (and this syntax is also supported).

This is equivalent to using the - operator (e.g. ops::Sub), as in flags - other.

pub const fn symmetric_difference(self, other: Self) -> Self

Returns the symmetric difference between the flags in self and other.

Specifically, the returned set contains the flags present which are present in self or other, but that are not present in both. Equivalently, it contains the flags present in exactly one of the sets self and other.

This is equivalent to using the ^ operator (e.g. ops::BitXor), as in flags ^ other.

pub const fn complement(self) -> Self

Returns the complement of this set of flags.

Specifically, the returned set contains all the flags which are not set in self, but which are allowed for this type.

Alternatively, it can be thought of as the set difference between Self::all() and self (e.g. Self::all() - self)

This is equivalent to using the ! operator (e.g. ops::Not), as in !flags.
