SynEdit is not the only custom control that was fixed by the change to BeginTextRender that disabled the fractional positioning of characters. This was an important fix since proportional font characters do not have whole number widths, yet they can only be displayed on a device using whole pixels. Without disabling this, then width(char) x number of chars in string <> width(string), which is what was causing the problem in SynEdit (and any other text editor type custom controls). Note that all char and string width functions return a whole number, so individual char widths get rounded.
Tobias, what fonts are you using? Could you post your example app. I'm not seeing the char positioning differences here. Please be careful making any changes to this. I believe Canvas.OutText calls ExtTextOut with DX=nil so the suggested workaround may break some other things that were fixed with the BeginTextRender change. Thanks. -Phil -----Original Message----- From: Mattias Gaertner [mailto:[EMAIL PROTECTED] Sent: Sat 11/3/2007 2:19 PM To: lazarus@miraclec.com Subject: Re: [lazarus] Carbon Widgetset: character spacing problems On Sat, 03 Nov 2007 20:14:02 +0100 Tobias Giesen <[EMAIL PROTECTED]> wrote: > > SynEdit needs disabled fractional positions.

Have you tried if DX<>nil then enable... else disable... ?
