Method Detail

animate

public void animate(long currentTime,
                    ClippingRegion repaintRegion)

Description copied from class: ItemView

Animates this item. Subclasses can override this method to create animations. The default implementation animates the background and the item view if present.

Overrides:

animate in class ContainerView

Parameters:

currentTime - the current time in milliseconds

repaintRegion - the repaint area that needs to be updated when this item is animated

See Also:

Item.getAbsoluteX(), Item.getAbsoluteY()

calculateNext

protected int calculateNext(int current,
                            int target,
                            long currentTime,
                            int completeDistance)

Calculates the next value

Parameters:

current - the current value

target - the target value

currentTime - the current time

completeDistance - the complete distance

Returns:

the next value

initAnimation

protected void initAnimation()

Initializes the animation.

showNotify

public void showNotify()

Description copied from class: ContainerView

Notifies this view that it is about to be shown (again). The default implementation just sets the restartAnimation-field to true.

Overrides:

showNotify in class ContainerView

initContent

protected void initContent(Item parentContainerItem,
                           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:

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

See Also:

ItemView.contentWidth, ItemView.contentHeight

paintContent

protected void paintContent(Container container,
                            Item[] myItems,
                            int x,
                            int y,
