Struct qt_3d_input::slots::SlotMouseDeviceMutPtr

pub struct SlotMouseDeviceMutPtr<'a> { /* private fields */ }

Allows to bind Qt signals with arguments (Qt3DInput::QMouseDevice*) to a Rust closure.

Create an object using new() and bind your closure using set(). The closure will be called with the signal’s arguments when the slot is invoked. Use connect() method of a qt_core::connection::Signal object to connect the signal to this slot. The closure will be executed each time the slot is invoked until source signals are disconnected or the slot object is destroyed.

The slot object takes ownership of the passed closure. If set() is called again, previously set closure is dropped. Make sure that the slot object does not outlive objects referenced by the closure.

If set() was not called, slot invokation has no effect.

Implementations

impl<'a> SlotMouseDeviceMutPtr<'a>

pub fn new<F: FnMut(*mut MouseDevice) + 'a>(f: F) -> SlotMouseDeviceMutPtr<'a>

Constructs a new object.

pub fn set<F: FnMut(*mut MouseDevice) + 'a>(&mut self, f: F)

Sets f as the callback closure. If set() is called again, previous closure is dropped.

pub fn clear(&mut self)

Drops the previously set closure, if any. After this, slot invokation will have no effect until a new closure is set.

Trait Implementations

impl<'a> Default for SlotMouseDeviceMutPtr<'a>

fn default() -> Self

Returns the “default value” for a type.

impl<'a> Receiver for SlotMouseDeviceMutPtr<'a>

type Arguments = (*mut MouseDevice,)

Tuple of argument types of this receiver.

fn object(&self) -> &Object

Returns reference to the QObject that owns this signal or slot.

fn receiver_id() -> &'static [u8]

Returns a null-terminated Latin-1 string that identifies this signal or slot within the owning QObject in Qt system.
