Gadget class.
Library: ilvgadgt
The IlvComboBox
class combines a text field (IlvTextField
class) with a pop-up menu displaying a set of predefined entries from which the user can choose.
- A Combo Box -
The user can enter a character string in the text field, or click on the arrow appearing on the right side of the field and select one of the choices from the menu that is displayed. The method getSubMenu()
gives access the pop-up menu attached to the combo box to modify its behavior.
The IlvCombBox
defines its own subclass of IlvPopupMenu
. It also provides a factory mechanism allowing to redefine the way to create and populate the popup menu with menu items.
- See also
- IlvScrolledComboBox, IlvOptionMenu.
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 IlvTextField and adds the following ones:
