Custom Collection
If the data structure of your application contains extra properties that needs to be displayed in the
item and the properties of the base collection are not sufficient, the TableView exposes 2 virtual
functions that can be overridden to add additional properties. The CustomCells demo that is
included in the distribution makes use of a TMSFMXNativeUITableViewMail instance that inherits
from the TMSFMXNativeUITableView and overrides the virtual functions that create the section and
item collection. When examining the code of this class, you will notice that the
TMSFMXNativeUITableViewMailItem collection item class is used to add additional properties such as
Sender, Date, Title, Description and Unread.
The TMSFMXNativeUITableViewMail inherits from TMSFMXNativeUITableView and overrides the
CreateSections function that returns the custom section collection
TMSFMXNativeUITableViewMailSections. As each section has an items collection, the CreateItems
function needs to be overridden to return the TMSFMXNativeUITableViewMailItems collection that
holds the customized items.
The creation of a custom collection can be sufficient to persist non-visual data in your application.
If you need additional visual representation in an item, then the Custom Items chapter will explain
how you can override the default layout of a TableView item and display custom data.
