Enum Event

#[non_exhaustive]
pub enum Event {
    Begin {
        serial: u32,
        time: u32,
        surface: WlSurface,
        fingers: u32,
    },
    End {
        serial: u32,
        time: u32,
        cancelled: i32,
    },
}

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Begin

multi-finger hold begin

This event is sent when a hold gesture is detected on the device.

Only available since version 3 of the interface

Fields

serial: u32

time: u32

timestamp with millisecond granularity

surface: WlSurface

fingers: u32

number of fingers

End

multi-finger hold end

This event is sent when a hold gesture ceases to be valid. This may happen when the holding fingers are lifted or the gesture is cancelled, for example if the fingers move past an implementation-defined threshold, the finger count changes or the hold gesture changes into a different type of gesture.

When a gesture is cancelled, the client may need to undo state changes caused by this gesture. What causes a gesture to be cancelled is implementation-dependent.

Only available since version 3 of the interface

Fields

serial: u32

time: u32

timestamp with millisecond granularity

cancelled: i32

1 if the gesture was cancelled, 0 otherwise
