Namespace:
Tizen.NUI
Assembly:
Tizen.NUI.dll

A set of key frames for a property that can be animated using DALi animation.
This allows the generation of key frame objects from individual Property::Values.

View Source

Add(float, PropertyValue)

Adds a key frame.

Declaration
public void Add(float progress, PropertyValue value)
Parameters
Type Name Description
float progress

A progress value between 0.0 and 1.0.
PropertyValue value

A value.
View Source

GetKeyFrame(uint, out float, PropertyValue)

Get the progress and value from specific key frame.
If index is greater or equal than total key frame count, progress and value is not changed.

Declaration
public void GetKeyFrame(uint index, out float progress, PropertyValue value)
Parameters
Type Name Description
uint index

The index of keyframe.
float progress

A progress value between 0.0 and 1.0.
PropertyValue value

A value.
View Source

GetKeyFrameCount()

Get the number of added key frame.

Declaration
public uint GetKeyFrameCount()
Returns
Type Description
uint

The number of key frames currently added to the KeyFrames object.
View Source

GetType()

Gets the type of the key frame.
An empty key frame will return PropertyType.None, wheras an initialised
key frame object will return the type of it's first element.

Declaration
public PropertyType GetType()
Returns
Type Description
PropertyType

The key frame property type

ReleaseSwigCPtr(HandleRef)

Declaration
protected override void ReleaseSwigCPtr(System.Runtime.InteropServices.HandleRef swigCPtr)
Parameters
Type Name Description
System.Runtime.InteropServices.HandleRef swigCPtr
Overrides
View Source

SetKeyFrameValue(uint, PropertyValue)

Set the value to specific key frame.
If index is greater or equal than total key frame count or value's PropertyType is not matched, Nothing happened.

Declaration
public void SetKeyFrameValue(uint index, PropertyValue value)
Parameters
Type Name Description
uint index

The index of keyframe.
PropertyValue value

A value.
