Struct ModifiersChangedEvent 

pub struct ModifiersChangedEvent {
    pub modifiers: Modifiers,
    pub capslock: Capslock,
}

A change to the modifier keys (Shift, Control, Alt, Platform, Function) or Caps Lock, sent without a key press.

Dereferences to Modifiers, so event.shift reads the new Shift state. Modifier-only bindings, such as one bound to "shift", are matched from this event.

Fields

modifiers: Modifiers

The modifier keys held after the change.

capslock: Capslock

The Caps Lock state after the change.

Methods from Deref<Target = Modifiers>

pub fn modified(&self) -> bool

Returns whether any modifier key is held.

pub fn secondary(&self) -> bool

Returns whether the platform’s shortcut modifier is held.

This is platform (command) on macOS and control on Linux and Windows. Use it for shortcuts such as save and copy, so that they follow each platform’s convention.

Examples

assert!(Modifiers::secondary_key().secondary());
assert!(!Modifiers::shift().secondary());

pub fn number_of_modifiers(&self) -> u8

Returns how many modifier keys are held.

pub fn is_subset_of(&self, other: &Modifiers) -> bool

Returns whether every modifier held in self is also held in other.

Modifiers::none() is a subset of every value, and no value is a subset of none() unless it is none() itself.

Examples

let ctrl_shift = Modifiers::control_shift();
assert!(Modifiers::shift().is_subset_of(&ctrl_shift));
assert!(!Modifiers::alt().is_subset_of(&ctrl_shift));
