Pradeep Kumar

I am trying to expose the properties of Qt to WinCC OA, i am using Q_PROPERTY for that,

Have u tried regarding how to expose the properties from Qt to WinCC OA, or do u have sample program for that,
We have property editor in WinCC OA, standard and extended property, how to expose for the property editor.

Thanks,

Hi
Sadly no. I only used DLLS to read PLC variables.

It sounds like you are making a custom control with the ODK?

There should be some methods in the ODK to allow visual editing of
user controls. I dont have it installed/access to CC anymore so
sadly I cant find more direct info.
I think its here about
http://w3.siemens.com/mcms/human-machine-interface/en/visualization-software/scada/wincc-options/wincc-odk/Pages/Default.aspx
I think there was a sample for a custom control.

However , the siemens have ok support so just call them and ask :)

That is understandable. The (data) ODK/SDK was a c interface and not super complex.
I imagine the custom control ODK to be the same.
