Library with all objects are exported in the the file. You can use this file to import library with all objects in a new project.
If you want to export your library with all objects and scripts that used these objects and also with screens that called from this object (for example button that call screen or popup screen) or with screens that called from the scripts bind to the object, you need to use Export library plus menu item. In this case in exported file you'll have object, scripts and screens.
If exported files contains only objects (you use Export library menu item during exporting library) only library with objects are created in the Add graphical object. If exported file also contains script and/or screens (you use Export library plus menu item during exporting library) these scripts and screens are added in the project and you can see them in the Project window.
Below you can find example how to create complex object with script and screen are bound to it. And how to add this object to the user-defined library, how to export this library and how to import it in the new project.
