Method Detail

initContent

protected void initContent(Item parentItm,
                           int firstLineWidth,
                           int availWidth,
                           int availHeight)

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:

parentItm - 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

ItemView.contentWidth, ItemView.contentHeight

focusItem

public Style focusItem(int focIndex,
                       Item item,
                       int direction,
                       Style focStyle)

Description copied from class: ContainerView

Focuses the given item and retrieves the previous style of that item. The default implementation sets the focusedIndex and focusedItem fields and returns the result of item.focus( focusStyle, direction ). This is a method that is usually called from within the parent Container (in contrast to the other focusItem() methods which forward the call to the parentContainer).

Overrides:

focusItem in class ContainerView

Parameters:

focIndex - the index of the item

item - the item which should be focused

direction - the direction, either Canvas.DOWN, Canvas.RIGHT, Canvas.UP, Canvas.LEFT or 0.

focStyle - the new style for the focused item

Returns:

the previous style of the focussed item

setStyle

protected void setStyle(Style style)

Description copied from class: ContainerView

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

Overrides:

setStyle in class ContainerView

Parameters:

style - the style

paintContent

protected void paintContent(Container container,
                            Item[] myItems,
