[−][src]Struct qt_widgets::RawSlotOfQIcon
Binds a Qt signal with arguments *const ::qt_gui::QIcon
to a Rust extern function.
It's recommended to use SlotOfQIcon
instead because it provides a more high-level API.
Corresponding C++ argument types: (const QIcon&
).
Create an object using new()
and bind your function and payload using set()
. The function will receive the payload as its first arguments, and the rest of arguments will be values passed through the Qt connection system. Use connect()
method of a qt_core::Signal
object to connect the signal to this slot. The callback function will be executed each time the slot is invoked until source signals are disconnected or the slot object is destroyed.
If set()
was not called, slot invocation has no effect.
Methods
impl RawSlotOfQIcon
[src]
pub unsafe fn custom_slot(&mut self, arg0: impl CastInto<Ref<QIcon>>)
[src]
Calls the slot directly, invoking the assigned handler (if any).
pub unsafe fn meta_object(&self) -> Ptr<QMetaObject>
[src]
pub unsafe fn new() -> CppBox<RawSlotOfQIcon>
[src]
Creates a new object.
pub unsafe fn qt_metacall(
&mut self,
arg1: Call,
arg2: c_int,
arg3: impl CastInto<MutPtr<*mut c_void>>
) -> c_int
[src]
&mut self,
arg1: Call,
arg2: c_int,
arg3: impl CastInto<MutPtr<*mut c_void>>
) -> c_int
pub unsafe fn qt_metacast(
&mut self,
arg1: impl CastInto<Ptr<c_char>>
) -> MutPtr<c_void>
[src]
&mut self,
arg1: impl CastInto<Ptr<c_char>>
) -> MutPtr<c_void>
pub unsafe fn set(
&mut self,
func: Option<extern "C" fn(_: *mut c_void, _: *const QIcon)>,
data: impl CastInto<MutPtr<c_void>>
)
[src]
&mut self,
func: Option<extern "C" fn(_: *mut c_void, _: *const QIcon)>,
data: impl CastInto<MutPtr<c_void>>
)
Assigns func
as the signal handler.
func
will be called each time a connected signal is emitted. Any previously assigned function will be deregistered. Passing None
will deregister the handler without setting a new one.
