When you return true in the MouseDown event, the event is stopped in the events chain. Why don't you simply put self.ef2.text=str(me.CharPosAtXY(X,Y)) in the MouseDown event? > SECOND PROBLEM : > If the user moves the caret with the keyboard arrows, the only > function > I can use is selStart(), with : > > self.ef2.text=str(me.SelStart) > > The problem is that selStart() doesn't work properly.

SelStart is the number of characters from the first character to where the insert point is. So, if you move up to one line, SelStart will decrease to <number of characters per line>. > IF YOU WANT TO REPRODUCE THIS BUG : > -Lay down two EditFields, ef1 and ef2.

Don't you confuse with the SelLength property? _______________________________________________ Unsubscribe or switch delivery mode: <http://www.realsoftware.com/support/listmanager/> Search the archives: <http://support.realsoftware.com/listarchives/lists.html>
