okay, that’s the scoop. Thank you for confirming.
So I was thinking of storing the path to the attribute I need to manage INTO
the widget.
I see I can do that simply enough, inside the SCRIPT for the CONTAINER.
I just put this into the script for the container (and enabled the ‘on load’
event for it).
: (Form event=On Load)
EXECUTE METHOD IN SUBFORM(OBJECT Get
Name;"SET_FORM_OBJ_ATTR";*;"myEntity.formDate”)
SET_FORM_OBJ_ATTR( ) merely assigns it to Form.sourceAttrPath in the widget.
This works okay.
…
I am trying to figure out how to trigger a CUSTOM EVENT in the subform. I will
name it on_WidgetUpdate (constant) -93
If I can trigger this custom event as needed, then the widgets can update
themselves by looking at the Form.sourceAttrPath to figure out where to update
from.
I am not clear on how I would trigger the event, though. Hopefully it can be
done in a ‘form-level’ way so that all the subforms (i.e. widgets) would
receive it automatically. But I could send it to each one if need be.
If you can tell me what I do, I would appreciate that (to trigger the custom
event).
I’m thinking I may have to use CALL SUBFORM CONTAINER ( on_WidgetUpdate ) and
then that container object will have to execute within the subform (EXECUTE
METHOD IN SUBFORM)
