lineWidth - the maximum width of any following lines

See Also:

                            int y,
                            int leftBorder,

isValid

protected boolean isValid(Item parent,
                          Style style)

Description copied from class: ItemView

Implementation that are valid only for specific item classes can override this method so that they cannot be accidently attached to unsupported classes. This allows casting without checking the parent item with instanceof in each method, for example. The default implementation just returns true for any case.

Overrides:

isValid in class ItemView

Parameters:

parent - the parent item

style - the style

Returns:

true when the view can be used for the parent item.

setStyle

protected void setStyle(Style style)

Description copied from class: ItemView

Sets the style for this view. The style can include additional parameters for the view. Subclasses should call super.setStyle(style) first.

Overrides:

Parameters:

style - the style
