}Expand description
Trait containing only the property related functions of ObjectImpl.
Implemented by the Properties macro.
When implementing ObjectImpl you may want to delegate the function calls to this trait.
Provided Methods§
sourcefn derived_properties() -> &'static [ParamSpec]
fn derived_properties() -> &'static [ParamSpec]
Properties installed for this type.
sourcefn derived_set_property(&self, _id: usize, _value: &Value, _pspec: &ParamSpec)
fn derived_set_property(&self, _id: usize, _value: &Value, _pspec: &ParamSpec)
Similar to ObjectImpl but auto-generated by the Properties macro
to allow handling more complex use-cases.
sourcefn derived_property(&self, _id: usize, _pspec: &ParamSpec) -> Value
fn derived_property(&self, _id: usize, _pspec: &ParamSpec) -> Value
Similar to ObjectImpl but auto-generated by the Properties macro
to allow handling more complex use-cases.
Object Safety§
This trait is not object safe.
