4.7. Preferences

In addition to the settings on the Import, Export, VIS Export and Database tabs, more preferences affecting the separate operations of the Importer/Exporter as well as general application settings are available on the Preferences tab shown below.


Fig. 4.89 The preferences dialog.

The preferences are organized into separate topics using a tree view [1] on the left side of the dialog. Simply navigate through this tree view by selecting, expanding and collapsing the separate tree nodes. When selecting a node, the associated settings dialog is displayed on the right side [2]. Changes made to the settings of the selected node are applied through the Apply button [3]. The buttons Restore and Default allow for resetting the preferences to their previous state or to their default values.

The preference settings offered by the Import, Export, and VIS Export nodes are not discussed in this chapter but in the context of the corresponding operations. Use the links below to directly jump to these chapters.

This chapter focuses on the Database and General preferences. The following table provides a summary overview of the available settings.

All preferences (including the settings on the separate operation tabs) are automatically stored in the configuration file of the Importer/Exporter and are restored from this file upon program start. Using the File menu [4] available from the menu bar of the Importer/Exporter, the preferences can optionally be stored in or loaded from user-defined configuration files (cf. Section 4.2).


In case plugins have been registered with the Importer/Exporter, each plugin might add another node to the preferences tree. Please refer to the manual of the plugin for a documentation of the preference settings.
