Tries to cast to an object of type T
. This handles upcasting, downcasting
and casting between interface and interface implementors. All checks are performed at
runtime, while downcast
and upcast
will do many checks at compile-time already. Read more

Same as connect_local
but takes a SignalId
instead of a signal name.

Same as connect_unsafe
but takes a SignalId
instead of a signal name.
Emit signal by signal id.
Same as emit
but takes Value
for the arguments.
Emit signal by its name.
Same as emit_by_name
but takes Value
for the arguments.
Emit signal with details by signal id.
Same as emit_with_details
but takes Value
for the arguments.
