605 *
606 * -- SHORT1FROMMP(mp1) usID: ID of the tooltip control).
607 *
608 * -- SHORT2FROMMP(mp1) usNotifyCode: TTN_NEEDTEXT.

610 * -- PTOOLTIPTEXT mp2: pointer to a TOOLTIPTEXT structure.
611 * hwndTool identifies the tool for which text is needed.
612 *
613 * This notification message is sent to the window specified
614 * in the hwndToolOwner member of the TOOLINFO structure for the tool.
615 * This notification is sent only if the PSZ_TEXTCALLBACK
616 * value is specified when the tool is added to a tooltip control.
617 *
618 * To specify the text, the target window (hwndToolOwner) must:
619 *
620 * 1. Set TOOLTIPTEXT.ulFormat to one of the format flags.
621 *
622 * 2. Fill the corresponding field(s) in TOOLTIPTEXT.
623 *
624 * Specifying PSZ_TEXTCALLBACK in TOOLINFO.lpszText with
625 * TTM_ADDTOOL is the only way under OS/2 to have strings
626 * displayed which are longer than 256 characters, since
627 * string resources are limited to 256 characters with OS/2.
628 * It is the responsibility of the application to set the
629 * pszText member to a _static_ string buffer which holds
630 * the string for the tool. A common error would be to have
631 * that member point to some variable which has only been
632 * allocated on the stack... this will lead to problems.
