Adding online help

Adding online help

SCO Visual Tcl provides direct support for two types of help:

Short help: provides a brief description of the highlighted widget which appears in the application without user input
Context-sensitive help: provides context-sensitive hooks into the SCOhelp system and appears in its own SCOhelp window based on user input: pressing the help key (usually <F1>) or choosing a help button or menu item

Additionally, you can write your own help procedure to access a different help browser by using the -helpCallback dialog class option. This callback, in conjunction with the -helpKeyCallback, allows you to specify your own help browser when the user presses the help key.

For information on environment variables affecting help, see ``The SCO Visual Tcl environment''.
