Display ToolTips for Combobox List items in Flex.

One of the readers asked this question, Is it possible to show ToolTips for the Combobox List items [on mouse over on each item i would like to show a ToolTip]?, and my answer was “YES”.And this post tells about that.

The First thing we got to remember here is the ToolTipManager Class and its methods.Basic information on how to create tooltips using this Class.

The ToolTipManager has two methods that let you programmatically use ToolTips. These methods are createToolTip() and destroyToolTip(), which you use to create and destroy new ToolTip objects. When you create a ToolTip object, you can customize it as you would any object, with access to its properties, styles, events, and effects.

[So explore more about this ToolTipManager Class to learn more], now we know how to create ToolTips using this Class, but how to show on the Combobox List items ?.Its simple using the ListEvent Class and on ListEvent.ITEM_ROLL_OVER raise an Event and write your code on the eventhandler to create tooltip.Check on the below code sample for this.And destroy the created tooltip on ListEvent.ITEM_ROLL_OUT.Isn’t that simple.

Run demo.

1.Download source code. –>This is with the itemRollOver,itemRollOut properties.

2.Download source code. –>This is with the addEventListener().
