The Data-On-Demand ListBox is a subclass of the native REALbasic ListBox and, as far as the end-user is concerned, will behave in the same way. The key difference for the programmer is that the Data-On-Demand ListBox does not store any data.
Rather, it is a "virtual" ListBox that relies on you, the programmer, to provide data, row-by-row, as requested. As a result, the Data-On-Demand ListBox is much faster at populating thousands of rows and, because you maintain the data, does not require you to coordinate changes from the data in your database to the ListBox.
What's New:
Significantly faster. Loading millions of records is now practically instant.
Added parameters to Reset so that the Data-On-Demand ListBox can be used in a tight loop.
Added other parameters and features to provide finer control at runtime.
New example for SQLite3 Professional.
Reduced memory requirements.
REALbasic 2005 or later is now required.
Requirements:
REALbasic 5.5 or later.
