598 *@@ TTN_NEEDTEXT:
599 * notification code used with WM_CONTROL when a tooltip
600 * needs a tooltip text for a tool.
601 *
602 * Parameters:
603 *
604 * -- SHORT1FROMMP(mp1) usID: ID of the tooltip control).
605 *
606 * -- SHORT2FROMMP(mp1) usNotifyCode: TTN_NEEDTEXT.
607 *
608 * -- PTOOLTIPTEXT mp2: pointer to a TOOLTIPTEXT structure.
609 * hwndTool identifies the tool for which text is needed.
610 *
611 * This notification message is sent to the window specified
612 * in the hwndToolOwner member of the TOOLINFO structure for the tool.
613 * This notification is sent only if the PSZ_TEXTCALLBACK
614 * value is specified when the tool is added to a tooltip control.
615 *
616 * To specify the text, the target window (hwndToolOwner) must:
617 *
618 * 1. Set TOOLTIPTEXT.ulFormat to one of the format flags.
619 *
620 * 2. Fill the corresponding field(s) in TOOLTIPTEXT.
621 *
622 * Specifying PSZ_TEXTCALLBACK in TOOLINFO.lpszText with
623 * TTM_ADDTOOL is the only way under OS/2 to have strings
624 * displayed which are longer than 256 characters, since
625 * string resources are limited to 256 characters with OS/2.
626 * It is the responsibility of the application to set the
627 * pszText member to a _static_ string buffer which holds
628 * the string for the tool. A common error would be to have
629 * that member point to some variable which has only been
630 * allocated on the stack... this will lead to problems.
