Enum gdk::CrossingMode

#[non_exhaustive]pub enum CrossingMode {
    Normal,
    Grab,
    Ungrab,
    GtkGrab,
    GtkUngrab,
    StateChanged,
    TouchBegin,

    // some variants omitted
}

Specifies the crossing mode for EventCrossing.

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.

Normal

crossing because of pointer motion.

Grab

crossing because a grab is activated.

Ungrab

crossing because a grab is deactivated.

GtkGrab

crossing because a GTK+ grab is activated.

GtkUngrab

crossing because a GTK+ grab is deactivated.

StateChanged

crossing because a GTK+ widget changed state (e.g. sensitivity).

TouchBegin

crossing because a touch sequence has begun, this event is synthetic as the pointer might have not left the window.

TouchEnd

crossing because a touch sequence has ended, this event is synthetic as the pointer might have not left the window.

DeviceSwitch

crossing because of a device switch (i.e. a mouse taking control of the pointer after a touch device), this event is synthetic as the pointer didn’t leave the window.

impl Ord for CrossingMode

fn cmp(&self, other: &CrossingMode) -> Ordering

This method returns an [Ordering] between self and other.

#[must_use]fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]fn clamp(self, min: Self, max: Self) -> Self

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl PartialEq<CrossingMode> for CrossingMode

fn eq(&self, other: &CrossingMode) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &CrossingMode) -> bool

This method tests for !=.

impl PartialOrd<CrossingMode> for CrossingMode

fn partial_cmp(&self, other: &CrossingMode) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &CrossingMode) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &CrossingMode) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &CrossingMode) -> bool
