Trait Initialize

pub trait Initialize: CxxQtType {
    // Required method
    fn initialize(self: Pin<&mut Self>);
}

This trait can be implemented on any CxxQtType to automatically define a default constructor that calls the initialize function after constructing a default Rust struct.

Ensure that the impl cxx_qt::Constructor<()> for ... {} is declared inside the CXX-Qt bridge. Alternatively, using impl cxx_qt::Initialize for ... {} acts as shorthand for the above line.

Example

#[cxx_qt::bridge]
mod qobject {
    extern "RustQt" {
        #[qobject]
        #[qproperty(i32, integer)]
        type MyStruct = super::MyStructRust;
    }

    // Remember to tell the bridge about the default constructor
    impl cxx_qt::Constructor<()> for MyStruct {}
    // or
    impl cxx_qt::Initialize for MyStruct {}
}

// Make sure the inner Rust struct implements `Default`
#[derive(Default)]
pub struct MyStructRust {
    integer: i32,
}

impl cxx_qt::Initialize for qobject::MyStruct {
    fn initialize(self: core::pin::Pin<&mut Self>) {
        self.on_integer_changed(|qobject| {
            println!("New integer value: {}", qobject.integer);
        }).release();
    }
}

Required Methods

fn initialize(self: Pin<&mut Self>)

This function is called to initialize the QObject after construction.
