File Browser to open Files

This file browser can be used to locate a graph or graph status file which shall be loaded and visualized in daVinci. Graph files are generated by the user or an application program (e.g. the graph editor) and should have the suffix .daVinci. They contain a term representation with the structure of a graph, but without layout informations (e.g. node coordinates). On the other side, a status file is always saved by daVinci itself and should have the suffix .status. A status contains the graph, the layout informations with the position of graph nodes and edges and most of the current user interface settings.

The browser has two views, one for the Directories and one for the Files in the current directory. The current directory is the one shown in the Selection field. To navigate through the directories, double-click on the elements in the Directories view. By clicking on '..', you move to the parent directory. To choose a file, either select it in the Files view and press the Open push button or simply double-click it. The browser beeps when you try to access a file or directory for which you do not have permissions, or when the specified file does not exist.

The file browser window can also be used mouseless with keyboard operations.
