Detailed Description

Gadget class.

Library: ilvadvgdt

The IlvStringList class lets you display and manipulate lists of gadget items. You can store up to 32768 items in a string list.

A String List

The main callback manages double-click events. Use the IlvStringList::setSelectCallback() method to track the selection.

See also: IlvGadgetItem

Accessors\nAccessors provide a scriptable and uniform way to inspect and modify an object by using its base class methods <tt>IlvValueInterface::queryValue()</tt>, <tt>IlvValueInterface::queryValues()</tt>, <tt>IlvValueInterface::changeValue()</tt>, <tt>IlvValueInterface::changeValues()</tt>.\n\n\nThis class inherits the accessors of its superclass \c IlvScrolledGadget and adds the following ones:
