Hi guy!

I have a big problem with the application what I've made, when I try
to run on Windows XP (sp3) with 'Windows XP' theme than the caption
from TpageControl TTabsheet disappears
If I change the theme from windows than to 'Windows Classic' then all
is ok!

Is possible to solve that? I’ve work on this application more than 2
weeks and now isn’t good for nothing

Ps. When I’ve developed the program than the windows theme was set to
‘classic’.

Thanks

I think that this bug have been solved last week. See here:

If this is your problem you can update Lazarus with SVN or download
latest snapshot.

Hi christensen.

  This is a limitation of Windows XP using the new designs - the tab
position must be set to top in order to be painted correct. I see the
same problem using Delphi 5. I don't know if this was fixed in Windows
Vista or Windows 7.

thanks Mr. Drigus for you answer.

Cannot test on Vista or W7 because I don't have.
I'm not pleased whit this restriction, I really liked the position of
tabsheet on left 
The same problem i had on my PNA(MIO)using WinCE 5.0 but in different
way, doesn't mater where i've positioned the Tabsheet it always show
at the bottom.

just a though..
have you tried selecting a fixed font and font size for the tabsheet
or it's parant? 
I've had problems in the past (win98 & XP) when I left vertical text
up to the OS to decide.

yes i've try: parent font, fixed font (Arial), character set, size,
color, different style but the same result

This is the problem of themed pagecontrol. Left and right tabs are not
supported by windows. There is a bug report already in the tracker
regards this problem. It can be solved only if LCL will draw tabs
itself.
