Struct PinchEvent 

pub struct PinchEvent {
    pub position: Point<Pixels>,
    pub delta: f32,
    pub modifiers: Modifiers,
    pub phase: TouchPhase,
}

A pinch gesture event from the platform, generated when the user performs a pinch-to-zoom gesture (typically on a trackpad).

Fields

position: Point<Pixels>

The position of the pinch center on the window.

delta: f32

The zoom delta for this event. Positive values indicate zooming in, negative values indicate zooming out. For example, 0.1 represents a 10% zoom increase.

modifiers: Modifiers

The modifiers that were held down during the pinch gesture.

phase: TouchPhase

The phase of the pinch gesture.

Methods from Deref<Target = Modifiers>

pub fn modified(&self) -> bool

Returns whether any modifier key is pressed.

pub fn secondary(&self) -> bool

Whether the semantically ‘secondary’ modifier key is pressed.

On macOS, this is the command key. On Linux and Windows, this is the control key.

pub fn number_of_modifiers(&self) -> u8

Returns how many modifier keys are pressed.

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

Checks if this Modifiers is a subset of another Modifiers.
