SearchContext.forwardAsync

void forwardAsync(gtk.text_iter.TextIter iter,  gio.cancellable.Cancellable cancellable =  null,  gio.types.AsyncReadyCallback callback =  null)

The asynchronous version of gtksource.search_context.SearchContext.forward.

See the documentation of gtksource.search_context.SearchContext.forward for more details.

See the #GAsyncResult documentation to know how to use this function.

If the operation is cancelled, the callback will only be called if cancellable was not null. gtksource.search_context.SearchContext.forwardAsync takes ownership of cancellable, so you can unref it after calling this function.

Parameters

`iter`	start of search.
`cancellable`	a #GCancellable, or null.
`callback`	a #GAsyncReadyCallback to call when the operation is finished.
