GTViewer 5.0 includes the Data Monitor functionality provided in GTVx. For more information on the Data Monitor see the previous Blog posting: The Data Monitor in GTVx.
The Data Monitor provides a powerful set of tools for displaying geographically oriented data that is of a temporary nature. One might compare the Data Monitor items to Redlines (or session graphics), but the Data Monitor items are more for conveying information to the user at the moment rather that providing a mechanism for sharing and storing data. Lighting Strikes, Vehicle Tracking, and Outage Management are the example I provided in the previous posting.
The Data Monitor has been withheld from GTViewer in the past because it usually requires more coding than typical External Apps, and if you are going to be doing that much customization, GTVx is usually a better solution. However, the Data Monitor turns out to be very useful in very simple applications just as a means of presenting information to the user. For example, an application might read a file of ticket information and show the tickets at their geographical locations with all of their corresponding data as tooltips. Currently, the Data Monitor in GTViewer and GTVx are identical providing the same set of methods and events. The Data Monitor consists of around 50 methods to create, modify, and delete items. Five events are provided to know when items are clicked, double-clicked, and when tooltips are displayed and hidden.
The Data Monitor has been a very powerful too in GTVx for several years. Now, this power is part of GTViewer as well.
