Tool Bar

The tool bar (see figure 4.10) consists of a set of buttons that are mainly short cuts for some menu items. The right half of the tool bar provides buttons for the creation of Telos objects.

Open a new frame (without connection):

Opens a new frame without a connection to a server. Within this frame, you can create new Telos objects, load existing layouts and save new layouts. Information about the graphical types is loaded from an XML file included in the JAR file
($CB_HOME/lib/classes/cb.jar).

Load layout:

see File Menu Load

Save layout:

see File Menu Save

Remove selected objects:

Removes the selected objects from the current graph. This operation has no effect on the current database, i.e. the objects will be not deleted from the database.

Open connection:

Opens a new frame with a new connection to a server. See File menu Connect to server.

Show object:

This operation adds a new object to the graph. You will be prompted to enter the object name of the object you want to add to the graph.

Show links between marked objects:

This operation will search for relationships between the selected objects. Do not select too many objects for this operation, queries have to be evaluated for n objects.

Creation of objects:

The following four buttons open the ``Create Object'' dialog to create new individual objects, attributes, instantiations, and specializations. See section 4.2.6 for more details.

Show added/removed objects:

Shows the objects that have been added or removed since the last commit (or since the window has been opened). Here, you can also select objects to undo the change, i.e. remove added objects or re-insert removed objects.

Commit:

Sends the changes to the server. The list of objects to be added or removed is transformed into a set of Telos frames and transferred to the server.
