interface nsITooltipTextProvider : nsISupports

/**
 * An interface implemented by a tooltip text provider service. This
 * service is called to discover what tooltip text is associated
 * with the node that the pointer is positioned over.
 *
 * Embedders may implement and register their own tooltip text provider
 * service if they wish to provide different tooltip text.
 *
 * The default service returns the text stored in the TITLE
 * attribute of the node or a containing parent.
 *
 * @note
 * The tooltip text provider service is registered with the contract
 * defined in NS_TOOLTIPTEXTPROVIDER_CONTRACTID.

Trait Implementations

impl XpCom for nsITooltipTextProvider

const IID: nsIID

IID: nsIID = nsID(2972230118, 17651, 17201, [143, 190, 90, 243, 96, 255, 33, 238])

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 nsITooltipTextProvider

unsafe fn addref(&self)

Increment the reference count.

unsafe fn release(&self)

Decrement the reference count, potentially freeing backing memory.

impl Deref for nsITooltipTextProvider

type Target = nsISupports

The resulting type after dereferencing.

fn deref(&self) -> &nsISupports

Dereferences the value.
