GORTO - Graphical Order Tool

Layout Adaptation

The following describes the possibilities of adaptation of GORTO to personal preferennces. The adaptation of GORTO is done by the resource mechanism of the X-Window-System, which can't be explained in detail here. In this paper only specific details of the implementation of GORTO is considered. For common explanations of resources see the original literature.

Resources of GORTO

GORTO uses several resources which are not related to any special widget. They rather have the status of globally used resources and are specified in the form of Gorto.Name. These are the following resources:

Internal Interface Structure

To allow sensible specification of resources the following internal interface structure of GORTO is given. The widgets used by GORTO are Athena widgets of the X Version 11, Release 4. The main window of GORTO shows the following widget structure:

Structure of Rule- and Symbol windows:

Structure of the window to select the according rules in symbol windows:

Structure of the dialogue window to hide attributes:

Structure of visit-sequences, Lido-source-text and announcements:

Graph Widget

The graph widget is a widget adapted to GORTO. It is used to describe different dependency graphs. It uses the widget class Core and doesn't provide new resources for the adaptation of the graph widget. The adaptation of graph widgets is done by certain actions at certain events. This binding up is done with the so called binding translations. For their description see the original literature.

Two actions are available: menu-popup() and select(). The action menu-popup() is used to call the menus within the dependency graphs and expects the internal name of a menu as a parameter. The action select() is used for adaptation of mouse and keyboard handling within dependency graphs. It accepts the following parameters which stand for user-commands described above:

Name              Objects              possible contexts
-------------------------------------------------------------
FOLLOW            dependencies         symbol, rules
FOLLOW-AND-CLOSE  dependencies         symbol, rules
FOLLOW-MARKED     dependencies         symbol, rules
REMOVE            added  dependencies  symbol, rules
HIDE              attributes           symbols, rules, visit-sequences
UNHIDE            attribute            symbols, visit-sequences
MOVE              attribute            symbols, visit-sequences
SPLIT-PARTITION   attributes           symbols
APPEND-PARTITION  attributes           symbols

The action select() is normally bound to the use of the mouse. Up to three parameters can be called to state the action to be executed depending to the selected object. If more than one parameter is given for the same object, only the last action will be executed the others are ignored. The default paramters for the graph-widget is the following:

<Btn3Down>: menu-popup(mainMenu) \n\
<BtnDown>:  select(FOLLOW) \n
