In this step you create a custom Framework manager to handle requests to change the background panel. To do this, display the Common Activities for the Framework and choose Create an IIP and a custom framework manager. Choose Create Only.
When the components have been created and snapped in, switch to the Visual LANSA editor and open your repository tracking list (see Create a Repository List to Track the Things You Create).
A custom IIP and a custom manager have been created for the Framework:
The custom IIP specifies the custom manager to be used.
Open the custom manager (XXX_CustomManager) and replace its source code with this code:
| Code Block |
|---|
Begin_Com Role(*EXTENDS #VF_AC036O) |
...
...
Define_Evt Name(ChangeBackgroundImage) |
...
Define_Map For(*input) Class(#PRIM_ALPH) Name(#ImageName) |
...
...
Define_Evt Name(ChangeBackgroundTextStyle) |
...
Define_Map For(*input) Class(#PRIM_vs.Style) Name(#ToStyle) Pass(*BY_REFERENCE) |
...
...
Mthroutine Name(RequestChangeBackgroundImage) |
...
Define_Map For(*input) Class(#PRIM_ALPH) Name(#ImageName) |
...
Signal Event(ChangeBackgroundImage) Imagename(#ImageName) |
...
Endroutine |
...
...
Mthroutine Name(RequestlChangeBackgroundTextStyle) |
...
Define_Map For(*input) Class(#PRIM_vs.Style) Name(#ToStyle) Pass(*BY_REFERENCE) |
...
Signal Event(ChangeBackgroundTextStyle) Tostyle(#ToStyle) |
...
Endroutine |
...
...
End_Com |
...
The custom manager now defines ChangeBackGroundImage and ChangeBackgroundTextStyle events which it signals when requested. Complile
Compile and close the custom manager.
