SetAutoPopupMenu(PM) - Assigns an auto-popup context menu to an object (and all child objects that do not have their own auto-popup menu). The automatic menu can be invoked by right-clicking (unless a right-click handler has been assigned to prevent this action), as well as by a specially designed key on the keyboard when the window is in focus (similarly, unless this key is prevented from being processed). See also the description of the TMenu object in the corresponding section;

HelpContext - the number used in the built-in help system to identify the visual element (to connect the help, the programmer must also perform additional steps, see HelpSupport);

AssignHelpContext(i)- "pass-through" (returns a pointer to Self) method for setting the value of the HelpContext property.
