Description copied from class: ContainerView

Initializes this container view. The implementation needs to calculate and set the contentWidth and contentHeight fields. The style of the focused item has already been set. 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
