Struct SampleGlobal 

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

This an example of the API that is generated for a global in .slint design markup. This may help you understand what functions you can call and how you can pass data in and out.

This is the source code:

export global SampleGlobal {
    in-out property<int> value;
    // ... maybe more callbacks or public functions here
}

Note: Globals are only accessible in Rust if they are exported from the root file or the slint! macro!

Implementations

impl<'a> SampleGlobal<'a>

pub fn get_value(&self) -> i32

A getter is generated for each property declared in the global. In this case, this is the getter that sets the value of the value property declared in the .slint design markup.

pub fn set_value(&self, value: i32)

A setter is generated for each property declared in the global. In this case, this is the setter that sets the value of the counter property declared in the .slint design markup.

Trait Implementations

impl<'a> Global<'a, SampleComponent> for SampleGlobal<'a>

The Global trait is implemented for each global. This allows accessing the global from its corresponding component (in this case SampleComponent) using the Global::get or ComponentHandle::global functions.

type StaticSelf = SampleGlobal<'static>

The Self type, with a 'static lifetime.

fn get(component: &'a SampleComponent) -> Self

Returns a reference to the global.

fn as_weak(&self) -> Weak<Self::StaticSelf>

Convert this Global reference into a weak reference.

impl StrongHandle for SampleGlobal<'static>

The StrongHandle trait is implemented for each global. It marks this component as holding a strong reference to the Slint element tree and allows using this component with a Weak reference.
