- I am looking into adopting InterViews for a production version of a prototype
- application platform written last year. The prototype uses Sun OLIT. Before
- even considering IV, I need to know that I can do one thing using IV that
- is critical to the package:
-
- The platform integrates a Geographical Information System with a GUI process.
- The GIS writes an X window that covers most of the screen; its operations
- are controlled by the GUI code. The GUI process gets the X window id of
- the GIS window and attaches it to an OLIT Stub widget, and adds an event
- handler for the Stub that gets all mouse cursor movement events (allowing
- screen-to-real-world coordinate conversion as the cursor moves).
-
- My understanding is that a goal of IV is to keep the IV programmer working
- exclusively at the object level and not do any direct X coding. Am I
- prevented from it? Do one or more IV classes provide some analog to the
- OLIT Stub, so that I can capture those mouse cursor movements using IV?
