Container is a component that receives special attention because all objects are created in containers and belongs to containers (except the most external one). The vital functionality of the whiteboard described in different chapters is in fact the functionality of containers.
Edition of a container is the same as the edition of the main board (the main panel of the whiteboard is also a container). The following key shortcuts are available:
- NIC - create new object/import an object/clone selected object
- DShiftD - delete selected object/delete all objects
- E - edit properties of selected object or of this container if nothing selected
- LShiftL - bring forward/send backward selected object
- GShiftG - group selected objects/ungroup selected object
- MShiftM - copy selected object to clipboard/paste from clipboard to the center of this container

GIF and JPEG images, files in wbd format and plain text can be imported
any whiteboard creation can be saved in wbd format (links to images) or as a postscript file
to import: select location and press Add or Replace button, or press Open icon
to export: press Save or Print icon

Note: the whiteboard you currently use may be NOT connected to the Tango collaboratory system
the system works in master-master mode:
- each participant have equal rights to perform editing
- initialization data is delivered by one participant
updates are not always sent immediately:
- creating - after creation is completed
- moving, resizing - when mouse raised
- modifying properties - when Apply or OK buttons are pressed in a Property Editor
- editing - after exiting editing mode
- other actions - immediately
some control over Tango session is provided by the Tango dialog
