Enables or Disables Actor Auto-Snap mode.

When Actor Auto-Snap mode has been enabled, ScrollView will automatically snap to the closest actor (The closest actor will appear in the center of the ScrollView).

Since:
3.0, DALi version 1.0.0
Parameters:
[in]enableEnables (true), or disables (false) Actor AutoSnap

Enables or Disables Axis Auto Lock mode for panning within the ScrollView.

When enabled, any pan gesture that appears mostly horizontal or mostly vertical, will be automatically restricted to horizontal only or vertical only panning, until the pan gesture has completed.

Since:
3.0, DALi version 1.0.0
Parameters:
[in]enableEnables (true), or disables (false) AxisAutoLock mode

Sets the gradient threshold at which a panning gesture should be locked to the Horizontal or Vertical axis.

By default, this is 0.36 (0.36:1) which means angles less than 20 degrees to an axis will lock to that axis.

Since:
3.0, DALi version 1.0.0
Parameters:
[in]gradientA value between 0.0 and 1.0 (auto-lock for all angles)
Note:
Specifying a value of 1.0 (the maximum value accepted) indicates that all panning gestures will auto-lock either to the horizontal or vertical axis.

This is a constant which multiplies the input touch flick velocity to determine the actual velocity at which to move the scrolling area.

Since:
3.0, DALi version 1.0.0
Parameters:
[in]speedThe flick speed coefficient (default = 1.0)

Sets the friction coefficient for ScrollView when flicking in free panning mode.

This is a value in stage-diagonals per second^2. stage-diagonal = Length( stage.width, stage.height ). example: A stage 480x800 in size has a diagonal length of 933. Friction coefficient of 1.0 means the swipe velocity will reduce by 1.0 * 933 pixels/sec^2.

Since:
3.0, DALi version 1.0.0
Parameters:
[in]frictionFriction coefficient must be greater than 0.0 (default = 1.0)

Sets the maximum flick speed for the ScrollView when flicking in free panning mode.

This is a value in stage-diagonals per second. stage-diagonal = Length( stage.width, stage.height ) example: A stage 480x800 in size has a diagonal length of 933. Max Flick speed of 1.0 means the maximum velocity of a swipe can be 1.0 * 933 pixels/sec.

Since:
3.0, DALi version 1.0.0
Parameters:
[in]speedMaximum flick speed (default = 3.0)
void Dali::Toolkit::ScrollView::SetMaxOvershoot ( float  overshootX,
float  overshootY

The final overshoot value is within 0.0f to 1.0f, but the maximum overshoot is in pixels (e.g. if you scroll 75 pixels beyond the edge of a scrollable area and the maximum overshoot is 100 then the final overshoot value will be 0.75f).

Since:
3.0, DALi version 1.0.0
