Methods

impl nsITextScroll

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

Cast this nsITextScroll to one of its base interfaces.

impl nsITextScroll

pub unsafe fn ScrollByLines(&self, numLines: int32_t) -> nsresult

/**
   * Scroll the view up or down by aNumLines lines. positive
   * values move down in the view. Prevents scrolling off the
   * end of the view.
   * @param numLines number of lines to scroll the view by
   */

void scrollByLines (in long numLines);

pub unsafe fn ScrollByPages(&self, numPages: int32_t) -> nsresult

/**
   * Scroll the view up or down by numPages pages. a page
   * is considered to be the amount displayed by the clip view.
   * positive values move down in the view. Prevents scrolling
   * off the end of the view.

Trait Implementations

impl XpCom for nsITextScroll

const IID: nsIID

IID: nsIID = nsID(108734624, 34687, 4563, [175, 126, 0, 160, 36, 255, 192, 140])

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 nsITextScroll

unsafe fn addref(&self)

Increment the reference count.

unsafe fn release(&self)

Decrement the reference count, potentially freeing backing memory.

impl Deref for nsITextScroll

type Target = nsISupports

The resulting type after dereferencing.

fn deref(&self) -> &nsISupports

Dereferences the value.
