Determines if the value should be clamped to the range between the minimum and maximum. If false and the value is outside of the range, the thumb will shrink as if the range were increasing.

In the following example, the clamping behavior is updated:

scrollBar.clampToRange = true;

The default value is false.

The default IStyleProvider for all SimpleScrollBar components.

The default value is null.

Determines if the scroll bar dispatches the Event.CHANGE event every time the thumb moves, or only once it stops moving.

In the following example, live dragging is disabled:

scrollBar.liveDragging = false;

The default value is true.

The maximum numeric value of the range.

In the following example, the maximum is changed to 100:

component.minimum = 0;
component.maximum = 100;
component.step = 1;
component.page = 10
component.value = 12;

The default value is 0.

See also

The minimum numeric value of the range.

In the following example, the minimum is changed to 0:

component.minimum = 0;
component.maximum = 100;
component.step = 1;
component.page = 10
component.value = 12;

The default value is 0.

See also

The amount the scroll bar value must change to get from one "page" to the next.

If this value is 0, the step value will be used instead. If the step value is 0, paging is not possible.

In the following example, the page is changed to 10:

scrollBar.minimum = 0;
scrollBar.maximum = 100;
scrollBar.step = 1;
scrollBar.page = 10
scrollBar.value = 12;

The default value is 0.

The time, in seconds, before actions are repeated. The first repeat happens after a delay that is five times longer than the following repeats.

In the following example, the repeat delay is changed to 500 milliseconds:

scrollBar.repeatDelay = 0.5;

The default value is 0.05.

The amount the value must change to increment or decrement.

In the following example, the step is changed to 1:

component.minimum = 0;
component.maximum = 100;
component.step = 1;
component.page = 10
component.value = 12;

The default value is 0.

The thumb sub-component.

For internal use in subclasses.

See also

A function used to generate the scroll bar's thumb sub-component. The thumb must be an instance of BasicButton. This factory can be used to change properties on the thumb when it is first created. For instance, if you are skinning Feathers components without a theme, you might use this factory to set skins and other styles on the thumb.

The function should have the following signature:

function():BasicButton

In the following example, a custom thumb factory is passed to the scroll bar:

scrollBar.thumbFactory = function():BasicButton
{
    var thumb:BasicButton = new BasicButton();
    var skin:ImageSkin = new ImageSkin( upTexture );
    skin.setTextureForState( ButtonState.DOWN, downTexture );
    thumb.defaultSkin = skin;
    return thumb;
};

The default value is null.

See also

An object that stores properties for the scroll bar's thumb, and the properties will be passed down to the thumb when the scroll bar validates. For a list of available properties, refer to feathers.controls.BasicButton.

If the subcomponent has its own subcomponents, their properties can be set too, using attribute @ notation. For example, to set the skin on the thumb which is in a SimpleScrollBar, which is in a List, you can use the following syntax:

list.verticalScrollBarProperties.@thumbProperties.defaultSkin = new Image(texture);

Setting properties in a thumbFactory function instead of using thumbProperties will result in better performance.

In the following example, the scroll bar's thumb properties are updated:

scrollBar.thumbProperties.defaultSkin = new Image( upTexture );
scrollBar.thumbProperties.downSkin = new Image( downTexture );

The default value is null.

See also

The value added to the styleNameList of the thumb. This variable is protected so that sub-classes can customize the thumb style name in their constructors instead of using the default style name defined by DEFAULT_CHILD_STYLE_NAME_THUMB.

To customize the thumb style name without subclassing, see customThumbStyleName.

See also

The current numeric value.

In the following example, the value is changed to 12:

component.minimum = 0;
component.maximum = 100;
component.step = 1;
component.page = 10
component.value = 12;

The default value is 0.

Constructor.

If the component's dimensions have not been set explicitly, it will measure its content and determine an ideal size for itself. If the explicitWidth or explicitHeight member variables are set, those value will be used without additional measurement. If one is set, but not the other, the dimension with the explicit value will not be measured, but the other non-explicit dimension will still need measurement.

Calls saveMeasurements() to set up the actualWidth and actualHeight member variables used for layout.

Meant for internal use, and subclasses may override this function with a custom implementation.

Creates and adds the thumb sub-component and removes the old instance, if one exists.

Dispatched when the user starts dragging the scroll bar's thumb.

The properties of the event object have the following values:

Dispatched when the scroll bar's value changes.

The properties of the event object have the following values:

Dispatched when the user stops dragging the scroll bar's thumb.

The properties of the event object have the following values:

Depending on the control, the result of the interaction may continue after the interaction ends. For instance, a Scroller may be "thrown", and the scrolling will continue animating after the user has finished interacting with it.

The minimum space, in pixels, to the left of the thumb.

In the following example, the left padding is changed to 20 pixels:

scrollBar.paddingLeft = 20;

The default value is 0.

See also

The minimum space, in pixels, below the thumb.

In the following example, the bottom padding is changed to 20 pixels:

scrollBar.paddingBottom = 20;

The default value is 0.

The minimum space, in pixels, to the right of the thumb.

In the following example, the right padding is changed to 20 pixels:

scrollBar.paddingRight = 20;

The default value is 0.

The minimum space, in pixels, above the thumb.

In the following example, the top padding is changed to 20 pixels:

scrollBar.paddingTop = 20;

The default value is 0.

Quickly sets all padding properties to the same value. The padding getter always returns the value of paddingTop, but the other padding values may be different.

In the following example, the padding is changed to 20 pixels:

scrollBar.padding = 20;

The default value is 0.

Determines if the scroll bar's thumb will be resized based on the scrollable range, or if it will be rendered at its preferred size.

In the following example, the thumb size is fixed:

scrollBar.fixedThumbSize = true;

The default value is false.

Determines if the scroll bar's thumb can be dragged horizontally or vertically. When this value changes, the scroll bar's width and height values do not change automatically.

Note: When using a SimpleScrollBar with a scrolling container, the container will automatically set the correct direction value. Generally, you should not need to set this style manually.

In the following example, the direction is changed to vertical:

scrollBar.direction = Direction.VERTICAL;

Note: The Direction.NONE constant is not supported.

The default value is feathers.layout.Direction.HORIZONTAL.

See also

A style name to add to the scroll bar's thumb sub-component. Typically used by a theme to provide different styles to different scroll bars.

In the following example, a custom thumb style name is passed to the scroll bar:

scrollBar.customThumbStyleName = "my-custom-thumb";

In your theme, you can target this sub-component style name to provide different styles than the default:

getStyleProviderForClass( Button ).setFunctionForStyleName( "my-custom-thumb", setCustomThumbStyles );

The default value is null.
