Description copied from class: ContainerView

When the contentWidth will be larger than the specified availWidth, the container view allows to scroll horizontally automatically using pointer events.

Overrides:

initContent in class ContainerView

Parameters:

parentContainerItem - the Container which uses this view, use parent.getItems() for retrieving all items.

firstLineWidth - the maximum width of the first line

availWidth - the maximum width of any following lines

availHeight - the maximum height of the view
