Brew MP 1.0.2
This function retrieves a pointer to the item widget at a certain index
in a list container widget. This function allows applications to modify
the visual appearance (like the background color) of a widget in response
to actions such as the user touching an item. When the application is
done with the widget it must release the widget, the releasing of the
widget is not done through a call to IWidget_Release, instead the user must
call IWidget_ReleaseItemWidget on the ListContainer widget with a pointer
to the item widget to release.
If the application gets a EVT_MDL_IDX_WIDGET_CHANGE model change
notification, then there has been a possible change to the widget/index
assignments in the ListContainer, so all previously acquired widgets (acquired using
IWidget_GetItemWidget) should be released with the IWidget_ReleaseItemWidget
[in] Pointer to the IWidget interface object.
[in] Index of item widget.
[out] Pointer to IWidget *, this will hold the item widget.
