Yes, you can model that in a way. But the beauty of GlazedLists is the use of the Decorator pattern which makes the use a breeze.
Have your EventList, which is basically a beefed up version of an ArrayList, decorate it and get all the filtering functionality alsmost automatically (only a few lines of code) wired up when using a decorated Textfield. Furthermore in Spring rich the setup of the table model is a breeze also, quite like using the grid in Tap5. What would be great would be a component which combines all this in one place. And unfortunately my expertise is probably not high enough to do it myself. My idea would be a component like Grid but with additional parameters for the filter fields and the Textfield automatically included. Maybe like FilteredGrid. The problem is to keep the parent List and the filtered List in sync always without hogging the memory too much. After all GlazedLists was developed for Swing apps where you don't have concurrent users in the app itself and all the system memory belongs to you. Propagation of database changes would anyways be too much to ask in either case.
