The thing is that you have to "measure" the string to calculate its dimensions given the font family, text size, font style etc. which I don't remember if TFont class provides itself in Delphi or if one had to use Windows calls for it (maybe it does provide). I was also thinking that I could reuse in the background an autosizing TLabel (there was such I think in Delphi) and set the text to it (=the font name itself) and the font name and keep some same font size, then tell it to size itself (without adding it to a parent - hope it doesn't play it clever in that case and do nothing), then ask it it's dimensions (so that I avoid messing with the font measuring calls if they're complex) I wonder why it should be a resource hog if fonts are implemented ok in Laz and in the OS or window manager. I've done it in JFC/Swing many years ago and it played very nice (JFC/Swing wasn't the most optimized lib back then [it still itsn't]). Also, old Macs were doing that (back in 1997) and didn't have problems. Anyway it will be a property to turn on/off. Think it's interesting exercise for me to get more comfortable with Laz object inspector code, so I'll try to give it a try Another thing I'd like to add is wiring option on the form designer, maybe similar to IBM's VisualAge or even simpler Cheers, George ---------------- George Birbilis ([EMAIL PROTECTED]) Computer & Informatics Engineer Microsoft MVP J# for 2004-2006 Borland "Spirit of Delphi" ++ QuickTime, Delphi, ActiveX, .NET components ++ http://www.kagi.com/birbilis ++ Robotics ++ http://www.mech.upatras.gr/~Robotics http://www.mech.upatras.gr/~robgroup _____ avast!
