Trait GObjectPropertyExpressionExt

pub trait GObjectPropertyExpressionExt: IsA<Object> {
    // Provided methods
    fn property_expression(&self, property_name: &str) -> PropertyExpression { ... }
    fn property_expression_weak(
        &self,
        property_name: &str,
    ) -> PropertyExpression { ... }
    fn this_expression(property_name: &str) -> PropertyExpression { ... }
}

Trait containing convenience methods in creating PropertyExpression that looks up a property of a glib::Object.

Example

label_expression is an Expression that looks up at Button’s label property.

use gtk::prelude::*;

let button = gtk::Button::new();
button.set_label("Label property");

let label_expression = button.property_expression("label");

Provided Methods

fn property_expression(&self, property_name: &str) -> PropertyExpression

Create an expression looking up an object’s property.

fn property_expression_weak(&self, property_name: &str) -> PropertyExpression

Create an expression looking up an object’s property with a weak reference.

fn this_expression(property_name: &str) -> PropertyExpression

Create an expression looking up a property in the bound this object.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
