ViewMenuLayout  - AS3 Flex

Package	spark.layouts
Class	public class ViewMenuLayout
Inheritance	ViewMenuLayout LayoutBase OnDemandEventDispatcher Object

The requestedMaxColumnCount property defines the maximum number of menu items in a row. By default, the property is set to three.

The ViewMenuLayout class define the layout as follows:

• If you define three or fewer menu items, where the requestedMaxColumnCount property contains the default value of three, the menu items are displayed in a single row. Each menu item has the same size.

  If you define four or more menu items, meaning more menu items than specified by the requestedMaxColumnCount property, the ViewMenu container creates multiple rows.

• If the number of menu items is evenly divisible by the requestedMaxColumnCount property, each row contains the same number of menu items. Each menu item is the same size.

  For example the requestedMaxColumnCount property is set to the default value of three and you define six menu items. The menu displays two rows, each containing three menu items.

• If the number of menu items is not evenly divisible by the requestedMaxColumnCount property, rows can contain a different number of menu items. The size of the menu items depends on the number of menu items in the row.

  For example the requestedMaxColumnCount property is set to the default value of three and you define eight menu items. The menu displays three rows. The first row contains two menu items. The second and third rows each contains three items.

You can create your own custom layout for the menu by creating your own layout class. By default, the spark.skins.mobile.ViewMenuSkin class defines the skin for the ViewMenu container. To apply a customized ViewMenuLayout class to the ViewMenu container, define a new skin class for the ViewMenu container.

The ViewMenuSkin class includes a definition for a Group container named contentGroup, as shown below:

    <s:Group id="contentGroup" left="0" right="0" top="3" bottom="2" 
        minWidth="0" minHeight="0"> 
        <s:layout> 
            <s:ViewMenuLayout horizontalGap="2" verticalGap="2" id="contentGroupLayout" 
                requestedMaxColumnCount="3" requestedMaxColumnCount.landscapeGroup="6"/> 
        </s:layout> 
    </s:Group>

To apply your customized ViewMenuLayout class, your skin class should define a container named contentGroup. That container uses the layout property to specify your customized layout class.
