Accessing online help with the 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 10–8. If the help event does not find an associated widget, it runs applhelp.p, the OpenEdge help calling interface. This procedure, applhelp.p, in <install-dir>\src\, displays the message, “No application help is available.”
Figure 10–8 depicts the behavior of the Progress HELP event.
