Struct qt_3d_core::RawSlotOfFloat

#[repr(C)]
pub struct RawSlotOfFloat { /* fields omitted */ }

Binds a Qt signal with arguments ::std::os::raw::c_float to a Rust extern function.

It's recommended to use SlotOfFloat instead because it provides a more high-level API.

Corresponding C++ argument types: (float).

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 RawSlotOfFloat

pub unsafe fn custom_slot(&mut self, arg0: c_float)

Calls the slot directly, invoking the assigned handler (if any).

pub unsafe fn meta_object(&self) -> Ptr<QMetaObject>

pub unsafe fn new() -> CppBox<RawSlotOfFloat>

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

pub unsafe fn qt_metacast(
    &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, _: c_float)>,
    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.

pub unsafe fn static_meta_object() -> Ref<QMetaObject>

pub unsafe fn tr(
    s: impl CastInto<Ptr<c_char>>,
    c: impl CastInto<Ptr<c_char>>,
    n: c_int
) -> CppBox<QString>

pub unsafe fn tr_utf8(
    s: impl CastInto<Ptr<c_char>>,
    c: impl CastInto<Ptr<c_char>>,
    n: c_int
) -> CppBox<QString>
