tree widget

[IBRAHIMALALI]

Good day ,

I have a question regarding the tree widget, what I am trying to do is:
1) once clicked on a certain level of the hierarchy in the tree I want to change visibility of some objects in the banner , I have done this but statically as if the id clicked on the tree equals some certain value then change visibility of some objects, what I want to do is to dynamically do this on some certain level in the tree no matter its name .
2) how it's possible to apply filter over the tree .

Thanks and regards .

ad 1) I don't understand your request
ad 2) you can change the visibility of items in the tree by using the tree method TREE1.setVisible()

Dear Martin Koller ,

I have a question regarding another topic please.

What is the default database used by wincc oa (the database that save the tags configuration , and everything else) , that is because we can only find access and files database , is there a method to use SQL server as default database . This is especially we have a very large scale project so we are not sure if we are not using SQL , it will hold the database.

Thanks for help.

The configuratiion of the data model (datapoint types, datapoints, configs, current alerts, current values) is stored in the RAIMA database of WinCC OA.
The files are located in the folder db/wincc_oa of the WinCC OA project.
To save historical data you can use
-- RAIMA for alerts in combination with the value archives (HDB) for the events
The historical data is also saved in folders located in db/wincc_oa.
-- Oracle for alerts and events (RDB)

There is no possibility to use another database as default database.

For detailed information please have a look at the WinCC OA documentation: System Management --> Database.
