Required methods
fn is<T: StaticType>(&self) -> bool
fn is<T: StaticType>(&self) -> bool
Returns true
if the object is an instance of (can be cast to) T
.

Safety
This function doesn’t store type information
Safety
The returned pointer can become invalid by a call to
set_qdata
, steal_qdata
, set_data
or steal_data
.
The caller is responsible for ensuring the returned value is of a suitable type

unsafe fn steal_qdata<QD: 'static>(&self, key: Quark) -> Option<QD>

&self,
signal_name: N,
after: bool,

F: Fn(&[Value]) -> Option<Value>,
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.
