Visualizations that are a “Dialog” visualization type and are used to prompt an input are instantiated automatically and managed by the internal dialog manager.

In the application, the dialog manager can be accessed via the also internal Visualization Manager by calling the method ‎GetDialogManager‎.

The dialog manager is provided with the following methods for handling a dialog.

NOTICE

You can program the method calls in function blocks or functions which are themselves called from the visualization by the action ‎Execute ST Code‎.

Moreover, you can program the method calls in the application code. Make sure that the call runs in ‎VISU_TASK‎. If this is not the case, then the behavior is undefined.
