Picture Functions

You can link functions to each picture, which will automatically be executed on opening or closing the picture. We will use this functionality now to open the button-bar with the start picture.

Select the node Pictures in the project manager.
In the detail view of the Project Manager select the picture Start Pic.
Open the section Execution in the properties window.
As Start function, select the function Picture switch: BB-Start from the list.

Now, whenever the picture Start pic is opened, the picture BB-Start will also be opened automatically.
