Trait containing all KeyframeTransition methods.

Implementors

KeyframeTransition

Required methods

pub fn clear(&self)[src]

Removes all key frames from self.

pub fn get_key_frame(&self, index_: u32) -> (f64, AnimationMode, Value)[src]

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

pub fn get_n_key_frames(&self) -> u32[src]

Retrieves the number of key frames inside self.

Returns

the number of key frames

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

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

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

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

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

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
