Summary
Important Observations
- Before you create a screen wrapper, name all the fields on the 5250 screen(s) that will be used in the wrapper
- You also need to ensure there is a navigation path to and from the destination screen to be wrapped.
- A screen wrapper is a Visual LANSA reusable part with Ancestor #VF_AC010 (command handler) which defines class #VF_SY122.
- In the screen wrapper, you start RAMP execution by invoking the MakerampTSavailable event. Once RAMP is running, you specify the destination screen the wrapper is to navigate to in the routine handling RampTSAvailable event.
- You use the ScreenWrapper.GetValue and ScreenWrapper.SetValue methods to pass values between the 5250 screens and the wrapper.
- You snap the screen wrapper into the Framework as you would snap in any non-RAMP command handler (using the business object properties, not RAMP Tools)
