5.12 User Action aiSee supports the concept of user actions. User action means that commands can be specified in GDL (see useractioncmd, p. 88). These commands are executed when one of the menu entries of the Auxiliaries menu is invoked. aiSee supports four commands to be specified in the graph description. They differ in the way that command line arguments are supplied to the command. The command specified for • user action 1 and 2 takes no argument at all, • user action 3 takes one argument, • user action 4 takes a list of arguments. The supplied arguments for user action 3 and 4 are a node title or a list of node titles respectively, i. e. before these commands are executed the user has to click a node or a set of nodes whose node titles are passed to the command. The menu entries corresponding to the user actions in the Auxiliaries menu can be specified in GDL as well with the useractionname (see p. 89) graph attribute. Example: User Action 01 ... 02 useractionname1: "Start netscape" 03 useractioncmd1: "netscape" 04 useractionname2: "Goto AbsInt" 05 useractioncmd2: "netscape http:\\www.AbsInt.com" 06 useractionname3: "Start aisee with one GDL file" 07 useractioncmd3: "aisee" 08 useractionname4: "Start aisee with several GDL files" 09 useractionname4: "aisee -multi" 10 ... 5.13 Character Set It is possible to switch the text colors or underlining within text output, e. g. drawing of labels or info fields. This is controlled by special characters in the strings. Note: The ASCII value of the control characters depends on the operating system and C compiler. The following control characters are allowed: • "\n" (ASCII code 10) Newline: drawing of text continues at the beginning of the next line. • "\t" (ASCII code 9) Tab: corresponds to eight space characters. 109
