hmm.. The reason for my use of the popup lists (triggers) is to allow a hierarchical representation of data. (e.g. subject, category, subcategory, then the final list, then data item). Current I perform this with 3 triggers that and 1 list. (e.g. after the subject is selected, I fill a popuplist with the categories, then etc.).
I would like the user to move left and right instead of having to select the item, but more importantly there's no way for them to navigate from category back to subject without using a stylus. I was hoping to allow a user with 5-way to total use our app without a stylus, but I guess that's too ideal. Can you think of another control that would perform the same tasks - without a major re-write? thanks - bill "Ben Combee" <[EMAIL PROTECTED]> wrote in message news:107305@palm-dev-forum... > > At 18:53 2003-1-2 -0800, you wrote: > >Ben Combee wrote: > > > When LstPopupList is running (such as when a popup trigger is > > > activated), the device is running in a separate event loop from your > > > application.
