In VLF-WIN the system IIP (Imbedded Interface Point) provide four methods that you can overload to perform special logic whenever the main window or a secondary window is opened or closed.
These are called:
- avMAINWindowReady – Main window has opened and is ready for work
- avSECONDWindowReady – Secondary window has opened and is ready for work
- avCloseMAINWindow – Main window is to be closed
- avCloseSECONDWindow – Secondary window is to be closed
Refer to Imbedded Interface Points (IIPs) and the shipped version of reusable part UF_SYSTM for more information about these methods and about how to implement you own IIPs.
