Struct gdk::WindowHints

pub struct WindowHints { /* private fields */ }

Used to indicate which fields of a Geometry struct should be paid attention to. Also, the presence/absence of POS, USER_POS, and USER_SIZE is significant, though they don’t directly refer to Geometry fields. USER_POS will be set automatically by GtkWindow if you call gtk_window_move(). USER_POS and USER_SIZE should be set if the user specified a size/position using a –geometry command-line argument; gtk_window_parse_geometry() automatically sets these flags.

Implementations

impl WindowHints

pub const POS: Self = Self{bits: ffi::GDK_HINT_POS as u32,}

indicates that the program has positioned the window

pub const MIN_SIZE: Self = Self{bits: ffi::GDK_HINT_MIN_SIZE as u32,}

min size fields are set

pub const MAX_SIZE: Self = Self{bits: ffi::GDK_HINT_MAX_SIZE as u32,}

max size fields are set

pub const BASE_SIZE: Self = Self{bits: ffi::GDK_HINT_BASE_SIZE as u32,}

base size fields are set

pub const ASPECT: Self = Self{bits: ffi::GDK_HINT_ASPECT as u32,}

aspect ratio fields are set

pub const RESIZE_INC: Self = Self{bits: ffi::GDK_HINT_RESIZE_INC as u32,}

resize increment fields are set

pub const WIN_GRAVITY: Self = Self{bits: ffi::GDK_HINT_WIN_GRAVITY as u32,}

window gravity field is set

pub const USER_POS: Self = Self{bits: ffi::GDK_HINT_USER_POS as u32,}

indicates that the window’s position was explicitly set by the user

pub const USER_SIZE: Self = Self{bits: ffi::GDK_HINT_USER_SIZE as u32,}

indicates that the window’s size was explicitly set by the user

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.
