Options Menu

The options will be stored in a configuration file (see section 4.5) when you exit the Graph Editor.

Language:

The text for menu items and buttons is available in two languages (German and English). With this option you can switch between the languages. Because of unknown reasons, this option does not work under Microsoft Windows.

Saving of Layouts:

This option determines whether the definition of the graphical types should be stored also in the layout file, when a layout is saved. This option is useful for offline usage of the Graph Editor (i.e., without a server) as all information necessary to visualize the graph will be included in the file.

Background Color:

Here you can change the background color of the graph to your favorite color.

Component View:

With this option, you can configure the view of an object if the component view is activated by a double click or by the popup menu. By default, a tree-like representation of the object with its classes, instances, super classes, subclasses, outgoing and incoming attributes is used. If you select ``Frame'', then the Telos frame of the object will be shown in a text area. (see figure 4.8)

Invalid Telos Objects:

The Graph Editor can validate objects that are currently shown in the graph, i.e. it checks whether the object is still valid in the database or it is has already been removed (see Current Connection menu). If you select ``Mark'' here, then the objects will be marked with a red cross as invalid. ``Remove from display instantly'' will remove the objects directly from the view.

Popup Menu:

These options control the behaviour of the Popup Menu (see section 4.2.5). The delay is the time (in milliseconds) an item of the popup menu has to be selected before the submenu is shown. Note that the construction of a submenu might require a query to the ConceptBase server. If the option ``Popup Menu blocks while waiting for server'' is activated, then the editor will block the UI while it waits for an answer of the ConceptBase server. Otherwise, the query to the server will be executed in a separate thread, and interaction with the UI will be possible. If you have the problem that some submenus are still shown after you have used the popup menu, set the delay to 0 and activate the option ``Popup Menu blocks while waiting for server''.
