Accessing Online Help with a Help Key

When a user presses the designated help key (usually F1 in Windows applications), a HELP event goes to the field-level widget with input focus in the current frame. If there is no trigger on the field-level widget, the HELP event goes to the current frame. The HELP event continues to move to the next level in the widget hierarchy as shown in Figure 1–10. If the help event does not find an associated widget, it runs applhelp.p, the Progress help calling interface. This procedure, applhelp.p, in c:\program files\progress\src\, displays the message, “No application help is available.” A sample interface, c:\program files\progress\src\samples\applhelp.p, provides an example of how you can modify applhelp.p for your application.

Figure 1–10 depicts the behavior of the Progress HELP event.
