The layout attempts to size all children to their preferred size. If there is enough space, each child is set to its preferred size, plus any excess space evenly distributed among the children.
If there is not enough space for all the children to be sized to their preferred size, then the children that are smaller than the average width are allocated their preferred size and the rest of the elements are reduced equally.
All children are set to the height of the parent.

Method | Defined By | ||
---|---|---|---|
Constructor. | ButtonBarHorizontalLayout | ||
OnDemandEventDispatcher | |||
Calculates the drop location in the data provider of the drop target for
the specified dragEvent. | LayoutBase | ||
When useVirtualLayout is true,
this method can be used by the layout target
to clear cached layout information when the target changes. | LayoutBase | ||
OnDemandEventDispatcher | |||
Called by the target after a layout element
has been added and before the target's size and display list are
validated. | LayoutBase | ||
This method must is called by the target after a layout element
has been removed and before the target's size and display list are
validated. | LayoutBase | ||
Returns the specified element's layout bounds as a Rectangle or null
if the index is invalid, the corresponding element is null,
includeInLayout=false,
or if this layout's target property is null. | LayoutBase | ||
Returns the change to the horizontal scroll position to handle
different scrolling options. | LayoutBase | ||
getNavigationDestinationIndex(currentIndex:int, navigationUnit:uint, arrowKeysWrapFocus:Boolean):int
Delegation method that determines which item
to navigate to based on the current item in focus
and user input in terms of NavigationUnit. | LayoutBase | ||
Computes the verticalScrollPosition and
horizontalScrollPosition deltas needed to
scroll the element at the specified index into view. | LayoutBase | ||
Returns the change to the horizontal scroll position to handle
different scrolling options. | LayoutBase | ||
OnDemandEventDispatcher | |||
Indicates whether an object has a specified property defined. | Object | ||
Hides the previously shown drop indicator,
created by the showDropIndicator() method,
removes it from the display list and also stops the drag scrolling. | LayoutBase | ||
Indicates whether an instance of the Object class is in the prototype chain of the object specified
as the parameter. | Object | ||
Measures the target's default size based on its content, and optionally
measures the target's default minimum size. | LayoutBase | ||
Indicates whether the specified property exists and is enumerable. | Object | ||
OnDemandEventDispatcher | |||
Sets the availability of a dynamic property for loop operations. | Object | ||
Sizes, positions and parents the drop indicator based on the specified
drop location. | LayoutBase | ||
Returns the string representation of this object, formatted according to locale-specific conventions. | Object | ||
Returns the string representation of the specified object. | Object | ||
Sizes and positions the target's elements. | LayoutBase | ||
Called by the target at the end of its updateDisplayList
to have the layout update its scrollRect. | LayoutBase | ||
Returns the primitive value of the specified object. | Object | ||
OnDemandEventDispatcher |
gap | property |
gap:int
Language Version: | ActionScript 3.0 |
Product Version: | Flex 4 |
Runtime Versions: | Flash Player 10, AIR 1.5 |
The horizontal space between layout elements. Note that the gap is only applied between layout elements, so if there's just one element, the gap has no effect on the layout.
The default value is 0.
