Detailed Description

Base class for derived Scrollables that contains actors that can be scrolled manually (via touch) or automatically.

Scrollables such as ScrollView and ItemView can be derived from this class.

Constructor & Destructor Documentation

Dali::Toolkit::Scrollable::Scrollable ( )

Creates an uninitialized Scrollable handle.

Since:: 2.4, DALi version 1.0.0

Dali::Toolkit::Scrollable::Scrollable ( const Scrollable & handle )

Copy constructor.

Creates another handle that points to the same real object.

Since:: 2.4, DALi version 1.0.0

Parameters:

handle to copy from

Dali::Toolkit::Scrollable::~Scrollable ( )

Destructor.

This is non-virtual since derived Handle types must not contain data or virtual methods.

Since:: 2.4, DALi version 1.0.0

Member Function Documentation

static Scrollable Dali::Toolkit::Scrollable::DownCast ( BaseHandle handle ) [static]

Downcasts a handle to Scrollable handle.

If handle points to a Scrollable, the downcast produces valid handle. If not, the returned handle is left uninitialized.

Since:: 2.4, DALi version 1.0.0

Parameters:

[in] handle Handle to an object

Returns:: A handle to a Scrollable or an uninitialized handle

Reimplemented from Dali::Toolkit::Control.

Reimplemented in Dali::Toolkit::ScrollView, and Dali::Toolkit::ItemView.

float Dali::Toolkit::Scrollable::GetOvershootAnimationSpeed ( ) const

Gets the speed of overshoot animation in pixels per second.

Since:: 2.4, DALi version 1.0.0

Returns:: The speed of the overshoot animation

Vector4 Dali::Toolkit::Scrollable::GetOvershootEffectColor ( ) const

Gets the color of the overshoot effect.

Since:: 2.4, DALi version 1.0.0

Returns:: The color of the overshoot effect

bool Dali::Toolkit::Scrollable::IsOvershootEnabled ( ) const

Checks if scroll overshoot has been enabled or not.

Since:: 2.4, DALi version 1.0.0

Returns:: Whether the scroll overshoot is enabled

Scrollable& Dali::Toolkit::Scrollable::operator= ( const Scrollable & handle )

Assignment operator.

Changes this handle to point to another real object.

Since:: 2.4, DALi version 1.0.0

Parameters:

[in] handle Handle to copy from

Returns:: A reference to this

ScrollCompletedSignalType& Dali::Toolkit::Scrollable::ScrollCompletedSignal ( )

Signal emitted when the Scrollable has completed movement (whether by touch or animation).

A callback of the following type may be connected:

   void YourCallbackName(const Vector2& currentScrollPosition);

Since:: 2.4, DALi version 1.0.0

Returns:: The signal to connect to

Precondition:: The Object has been initialized.

ScrollStartedSignalType& Dali::Toolkit::Scrollable::ScrollStartedSignal ( )

Signal emitted when the Scrollable has moved (whether by touch or animation).

A callback of the following type may be connected:

   void YourCallbackName(const Vector2& currentScrollPosition);

Since:: 2.4, DALi version 1.0.0

Returns:: The signal to connect to

Precondition:: The Object has been initialized.

ScrollUpdatedSignalType& Dali::Toolkit::Scrollable::ScrollUpdatedSignal ( )

Signal emitted when the Scrollable has moved (whether by touch or animation).

A callback of the following type may be connected:

   void YourCallbackName(const Vector2& currentScrollPosition);

Since:: 2.4, DALi version 1.0.0

Returns:: The signal to connect to

Precondition:: The Object has been initialized.

void Dali::Toolkit::Scrollable::SetOvershootAnimationSpeed ( float pixelsPerSecond )

Sets the speed of overshoot animation in pixels per second.

When the speed is not greater than 0, the overshoot is set instantly with no animation.

Since:: 2.4, DALi version 1.0.0

Parameters:

[in] pixelsPerSecond The speed of the overshoot animation

void Dali::Toolkit::Scrollable::SetOvershootEffectColor ( const Vector4 & color )

Sets the color of the overshoot effect.

Since:: 2.4, DALi version 1.0.0

Parameters:

[in] color The color of the overshoot effect

void Dali::Toolkit::Scrollable::SetOvershootEnabled ( bool enable )

Sets whether to enables or disable scroll overshoot.

Since:: 2.4, DALi version 1.0.0

Parameters:

[in] enable Whether to enable the scroll overshoot or not
