Struct gdk::ModifierType

pub struct ModifierType { /* private fields */ }

A set of bit-flags to indicate the state of modifier keys and mouse buttons in various event types. Typical modifier keys are Shift, Control, Meta, Super, Hyper, Alt, Compose, Apple, CapsLock or ShiftLock.

Like the X Window System, GDK supports 8 modifier keys and 5 mouse buttons.

Since 2.10, GDK recognizes which of the Meta, Super or Hyper keys are mapped to Mod2 - Mod5, and indicates this by setting SUPER_MASK, HYPER_MASK or META_MASK in the state field of key events.

Note that GDK may add internal values to events which include reserved values such as MODIFIER_RESERVED_13_MASK. Your code should preserve and ignore them. You can use MODIFIER_MASK to remove all reserved values.

Also note that the GDK X backend interprets button press events for button 4-7 as scroll events, so BUTTON4_MASK and BUTTON5_MASK will never be set.

Implementations

impl ModifierType

pub const SHIFT_MASK: Self = _

the Shift key.

pub const LOCK_MASK: Self = _

a Lock key (depending on the modifier mapping of the X server this may either be CapsLock or ShiftLock).

pub const CONTROL_MASK: Self = _

the Control key.

pub const MOD1_MASK: Self = _

the fourth modifier key (it depends on the modifier mapping of the X server which key is interpreted as this modifier, but normally it is the Alt key).

pub const MOD2_MASK: Self = _

the fifth modifier key (it depends on the modifier mapping of the X server which key is interpreted as this modifier).

pub const MOD3_MASK: Self = _

the sixth modifier key (it depends on the modifier mapping of the X server which key is interpreted as this modifier).

pub const MOD4_MASK: Self = _

the seventh modifier key (it depends on the modifier mapping of the X server which key is interpreted as this modifier).

pub const MOD5_MASK: Self = _

the eighth modifier key (it depends on the modifier mapping of the X server which key is interpreted as this modifier).

pub const BUTTON1_MASK: Self = _

the first mouse button.

pub const BUTTON2_MASK: Self = _

the second mouse button.

pub const BUTTON3_MASK: Self = _

the third mouse button.

pub const BUTTON4_MASK: Self = _

the fourth mouse button.

pub const BUTTON5_MASK: Self = _

the fifth mouse button.

pub const MODIFIER_RESERVED_13_MASK: Self = _

A reserved bit flag; do not use in your own code

pub const MODIFIER_RESERVED_14_MASK: Self = _

A reserved bit flag; do not use in your own code

pub const MODIFIER_RESERVED_15_MASK: Self = _

A reserved bit flag; do not use in your own code

pub const MODIFIER_RESERVED_16_MASK: Self = _

A reserved bit flag; do not use in your own code

pub const MODIFIER_RESERVED_17_MASK: Self = _

A reserved bit flag; do not use in your own code

pub const MODIFIER_RESERVED_18_MASK: Self = _

A reserved bit flag; do not use in your own code

pub const MODIFIER_RESERVED_19_MASK: Self = _

A reserved bit flag; do not use in your own code

pub const MODIFIER_RESERVED_20_MASK: Self = _

A reserved bit flag; do not use in your own code

pub const MODIFIER_RESERVED_21_MASK: Self = _

A reserved bit flag; do not use in your own code

pub const MODIFIER_RESERVED_22_MASK: Self = _

A reserved bit flag; do not use in your own code

pub const MODIFIER_RESERVED_23_MASK: Self = _

A reserved bit flag; do not use in your own code

pub const MODIFIER_RESERVED_24_MASK: Self = _

A reserved bit flag; do not use in your own code

pub const MODIFIER_RESERVED_25_MASK: Self = _

A reserved bit flag; do not use in your own code

pub const SUPER_MASK: Self = _

the Super modifier. Since 2.10

pub const HYPER_MASK: Self = _

the Hyper modifier. Since 2.10

pub const META_MASK: Self = _

the Meta modifier. Since 2.10

pub const MODIFIER_RESERVED_29_MASK: Self = _

A reserved bit flag; do not use in your own code

pub const RELEASE_MASK: Self = _

not used in GDK itself. GTK+ uses it to differentiate between (keyval, modifiers) pairs from key press and release events.

pub const MODIFIER_MASK: Self = _

a mask covering all modifier types.

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.
