CONTROL: Propogating an event from reference panel to owner

[willw]

I have a graphics object used as a reference with a push button on it. Within the click handler, I need to propagate the event to code in the owning panel, ie I want to do something like this:

Code: Select all

?// [pbRefPanel] [1] - [Clicked]
main() 
{ // Handler for button click
  parent.handleMyClick($SomeParam);
}

I think I could achieve this effect by creating a DP and writing to it; I'd rather keep the whole thing in code in the panels, rather than create extra dependencies on entities that exist outside the panels in the code.

TIA

Currently there's no other way than using an internal DP

As I feared. Thanks for that.

If I understood the presentation at the User Days in London properly, this should be possible with the new implemtation of object oriented panels feature that was announced for WinCC OA V3.15.

Yes, correct.
