The following handler, that doesn't use formattedHeight, works for me. -- VERTICAL CENTERING OF TEXT [-hh, Apr 16] -- This is independent of any text formatting, the only -- assumption is that ALL of the field's text is visible. on verticalCenter -- 'me' is the field (may be via 'behavior') lock screen; lock messages put the traversalOn of me into trv set traversalOn of me to true --> for using 'select' put the height of me into h put cr & cr after me select after char -2 of me put item 2 of the selectedLoc of me into v1 select before char 1 of me put item 2 of the selectedLoc of me into v0 delete char -2 to -1 of me set topmargin of me to (h + v0 - v1) div 2 set traversalOn of me to trv unlock screen; unlock messages end verticalCenter Note. Of course the same technique, now using vscroll instead of topmargin, works for centering the line of a highlighted text portion in a scrolling field (if NOT all text of the field is visible). -- View this message in context: http://runtime-revolution.278305.n4.nabble.com/Set-Text-to-the-Vertical-Center-of-the-field-tp4702965p4702979.html Sent from the Revolution - User mailing list archive at Nabble.com. _______________________________________________ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
