Provided Methods§

Source

fn set_child_property( &self, property_name: &str, value: impl Into<Value>, ) -> Result<(), BoolError>

See TimelineElementExt::set_child_property_full(), which also gives an error.

Note that ges_timeline_element_set_child_properties() may be more convenient for C programming.

§property_name

The name of the child property to set

§value

The value to set the property to

§Returns

true if the property was found and set.

Source

fn set_child_property_by_pspec( &self, pspec: impl AsRef<ParamSpec>, value: impl Into<Value>, )

Sets the property of a child of the element. Specifically, the property corresponding to the pspec used in TimelineElementExt::add_child_property() is set to value.

§pspec

The specification of a registered child property to set

§value

The value to set the property to

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.
