Trait containing all KeyframeTransition methods.

KeyframeTransition

Required Methods

fn clear(&self)

Removes all key frames from self.

fn get_key_frame(&self, index_: u32) -> (f64, AnimationMode, Value)

Retrieves the details of the key frame at index_ inside self.

The self must already have key frames set, and index_ must be smaller than the number of key frames.

index_

the index of the key frame

key

return location for the key, or None

mode

return location for the easing mode, or None

value

a gobject::Value initialized with the type of the values

fn get_n_key_frames(&self) -> u32

Retrieves the number of key frames inside self.

Returns

the number of key frames

fn set_key_frame( &self, index_: u32, key: f64, mode: AnimationMode, value: &Value, )

Sets the details of the key frame at index_ inside self.

The self must already have a key frame at index_, and index_ must be smaller than the number of key frames inside self.

index_

the index of the key frame

key

the key of the key frame

mode

the easing mode of the key frame

value

a gobject::Value containing the value of the key frame

fn set_key_frames(&self, key_frames: &[f64])

Sets the keys for each key frame inside self.

If self does not hold any key frame, n_key_frames key frames will be created; if self already has key frames, key_frames must have at least as many elements as the number of key frames.

n_key_frames

the number of values

key_frames

an array of keys between 0.0 and 1.0, one for each key frame

fn set_values(&self, values: &[&Value])

Sets the values for each key frame inside self.

If self does not hold any key frame, n_values key frames will be created; if self already has key frames, values must have at least as many elements as the number of key frames.

n_values

the number of values

values

an array of values, one for each key frame

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
