Methods

impl nsISliderListener

pub fn coerce<T: nsISliderListenerCoerce>(&self) -> &T

Cast this nsISliderListener to one of its base interfaces.

impl nsISliderListener

    &self,
    which: &nsAString,
    newValue: int32_t,
    userChanged: bool
) -> nsresult

/**
   * Called when the current, minimum or maximum value has been changed to
   * newValue. The which parameter will either be 'curpos', 'minpos' or 'maxpos'.
   * If userChanged is true, then the user changed ths slider, otherwise it
   * was changed via some other means.
   */

void valueChanged (in AString which, in long newValue, in boolean userChanged);

pub unsafe fn DragStateChanged(&self, isDragging: bool) -> nsresult

/**
   * Called when the user begins or ends dragging the thumb.
   */

Trait Implementations

impl XpCom for nsISliderListener

const IID: nsIID

IID: nsIID = nsID(3853715278, 60952, 17720, [131, 185, 36, 135, 217, 10, 42, 52])

fn query_interface<T: XpCom>(&self) -> Option<RefPtr<T>>

Perform a QueryInterface call on this object, attempting to dynamically cast it to the requested interface type. Returns Some(RefPtr) if the cast succeeded, and None otherwise.

impl RefCounted for nsISliderListener

unsafe fn addref(&self)

Increment the reference count.

unsafe fn release(&self)

Decrement the reference count, potentially freeing backing memory.

impl Deref for nsISliderListener

type Target = nsISupports

The resulting type after dereferencing.

fn deref(&self) -> &nsISupports

Dereferences the value.
