class BaseScrollContainer

Determines if the scroll bars should be automatically hidden after scrolling has ended, whether it was through user interaction or animation.

In the following example, scroll bar auto-hiding is disabled:

container.autoHideScrollBars = false;

This property has no effect if fixedScrollBars is true. Fixed scroll bars are always visible. Similarly, if showScrollBars is false, then the scroll bars are always hidden.

The default background skin to display behind all content added to the group. The background skin is resized to fill the complete width and height of the group.

The following example passes a bitmap for the container to use as a background skin:

group.backgroundSkin = new Bitmap(bitmapData);

See also:

• BaseScrollContainer.disabledBackgroundSkin

The default background skin to display behind all content added to the group. The background skin is resized to fill the complete width and height of the group.

The following example gives the group a disabled background skin:

group.disabledBackgroundSkin = new Bitmap(bitmapData);
group.enabled = false;

• BaseScrollContainer.backgroundSkin

Determines if the scrolling can go beyond the edges of the viewport when dragging with a touch.

In the following example, elastic edges are disabled:

container.elasticEdges = false;

Determines if the scroll bars are fixed to the edges of the container, without overlapping the container's content, or if the scroll bars are floating above the container's content.

In the following example, the scroll bars are fixed:

container.fixedScrollBars = true;

This property has no effect if showScrollBars is false.

The duration, measured in seconds, of the animation when a scroll bar fades out.

In the following example, the duration of the animation that hides the scroll bars is set to 500 milliseconds:

container.hideScrollBarDuration = 0.5;

The easing function used for hiding the scroll bars, if applicable.

In the following example, the ease of the animation that hides the scroll bars is customized:

container.hideScrollBarEase = Elastic.easeOut;

The number of pixels the container may be scrolled horizontally in the rightward direction. This value is automatically calculated based on the bounds of the container's viewport.

The scrollX property may have a higher value than the maximum if the elasticEdges property is enabled. However, once the user stops interacting with the container, it will automatically animate back to the maximum position.

See also:

• BaseScrollContainer.scrollX

• BaseScrollContainer.maxScrollX

The number of pixels the container may be scrolled vertically in the downward direction. This value is automatically calculated based on the bounds of the container's viewport.

The scrollY property may have a higher value than the maximum if the elasticEdges property is enabled. However, once the user stops interacting with the container, it will automatically animate back to the maximum position.

See also:

• BaseScrollContainer.scrollY

• BaseScrollContainer.minScrollY

The number of pixels the container may be scrolled horizontally in the leftward direction. This value is automatically calculated based on the bounds of the container's viewport.

The scrollX property may have a lower value than the minimum if the elasticEdges property is enabled. However, once the user stops interacting with the container, it will automatically animate back to the minimum position.

See also:

• BaseScrollContainer.scrollX

• BaseScrollContainer.maxScrollX

The number of pixels the container may be scrolled vertically in the upward direction. This value is automatically calculated based on the bounds of the container's viewport.

The scrollY property may have a lower value than the minimum if the elasticEdges property is enabled. However, once the user stops interacting with the container, it will automatically animate back to the minimum position.

See also:

• BaseScrollContainer.scrollY

• BaseScrollContainer.maxScrollY

The minimum space, in pixels, between the container's bottom edge and the container's content.

In the following example, the container's bottom padding is set to 20 pixels:

container.paddingBottom = 20.0;

The minimum space, in pixels, between the container's left edge and the container's content.

In the following example, the container's left padding is set to 20 pixels:

container.paddingLeft = 20.0;

The minimum space, in pixels, between the container's right edge and the container's content.

In the following example, the container's right padding is set to 20 pixels:

container.paddingRight = 20.0;

The minimum space, in pixels, between the container's top edge and the container's content.

In the following example, the container's top padding is set to 20 pixels:

container.paddingTop = 20.0;

Determines the edge of the container where the horizontal scroll bar will be positioned (either on the top or the bottom).

In the following example, the horizontal scroll bar is positioned on the top edge of the container:

container.scrollBarXPosition = TOP;

See also:

• feathers.layout.RelativePosition.BOTTOM

• feathers.layout.RelativePosition.TOP

Determines the edge of the container where the vertical scroll bar will be positioned (either on the left or the right).

In the following example, the vertical scroll bar is positioned on the left edge of the container:

container.scrollBarYPosition = LEFT;

See also:

• feathers.layout.RelativePosition.RIGHT

• feathers.layout.RelativePosition.LEFT

Determines whether the container may scroll horizontally (on the x-axis) or not.

In the following example, horizontal scrolling is disabled:

container.scrollPolicyX = OFF;

See also:

• BaseScrollContainer.scrollPolicyY

Determines whether the container may scroll vertically (on the y-axis) or not.

In the following example, vertical scrolling is disabled:

container.scrollPolicyY = OFF;

See also:

• BaseScrollContainer.scrollPolicyX

The number of pixels the horizontal scroll position can be adjusted by a step (such as with the left/right keyboard arrow keys, or a step button on the horizontal scroll bar).

In the following example, the horizontal scroll step is set to 20 pixels:

container.scrollStepX = 20.0;

The number of pixels the vertical scroll position can be adjusted by a step (such as with the up/down keyboard arrow keys, or a step button on the vertical scroll bar).

In the following example, the vertical scroll step is set to 20 pixels:

container.scrollStepY = 20.0;

The number of pixels the container has been scrolled horizontally (on the x-axis).

When the value of scrollX changes, the container dispatches an event of type ScrollEvent.SCROLL. This event is dispatched when other scroll position properties change too.

In the following example, the horizontal scroll position is modified immediately, without being animated:

container.scrollX = 100.0;

See also:

• BaseScrollContainer.minScrollX

• BaseScrollContainer.maxScrollX

• feathers.events.ScrollEvent.SCROLL

The number of pixels the container has been scrolled vertically (on the y-axis).

When the value of scrollY changes, the container dispatches an event of type ScrollEvent.SCROLL. This event is dispatched when other scroll position properties change too.

In the following example, the vertical scroll position is modified immediately, without being animated:

container.scrollY = 100.0;

See also:

• BaseScrollContainer.minScrollY

• BaseScrollContainer.maxScrollY

• feathers.events.ScrollEvent.SCROLL

Determines if scroll bars are displayed or not.

In the following example, the scroll bars are hidden:

container.showScrollBars = false;

When simulating touch, mouse events are treated as if they were mouse events instead, allowing the user to click and drag the container with momentum scrolling using the mouse instead of touch.

Generally, this is intended for testing during development and should not be used in production.

container.simulateTouch = true;

The display object rendered and scrolled within the container, provided by a subclass of BaseScrollContainer.

Creates the horizontal scroll bar. The horizontal scroll bar may be any implementation of IScrollBar, but typically, the feathers.controls.HScrollBar component is used.

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

scroller.scrollBarXFactory = () ->
{
	return new HScrollBar();
};

See also:

• feathers.controls.HScrollBar

Creates the vertical scroll bar. The vertical scroll bar may be any implementation of IScrollBar, but typically, the feathers.controls.VScrollBar component is used.

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

scroller.scrollBarYFactory = () ->
{
	return new VScrollBar();
};
