Displaying Help Panels

Help panels are displayed in help windows by IPF as a result of user interaction. A user may cause a help panel to be displayed in one of three ways:

  • Hitting the F1 key

  • Selecting a "Help" item on the menu bar or a pulldown menu

  • Pressing a Help pushbutton in a dialog box.

    Each of these actions normally results in a WM_HELP message being generated. This message is trapped by IPF, which then determines the active application window and uses the current help table to identify the help panel for that window.
