    Tab control tab font question

    Trying to work out how to change the font used in the tab part of a tab control. Is this possible without ownerdrawing the tab control? WM_SETFONT does not appear to do the job. Looking at the TCM_ messages, there is nothing obviously helpful.

    this is an excerpt from QTAB....

    Code:
        '---CHANGE MAIN TAB FONT...
    IF lfApply.lfHeight THEN
        'create the new font using the LOGFONT structure...

        hDC& = GetDC(hDlg)
            fpt& = (lfApply.lfHeight * 72) / -GetDeviceCaps(hDC&, %LOGPIXELSY)
        ReleaseDC hDlg, hDC&

        hFont& = MakeFontEx(lfApply.lfFaceName,fpt&,lfApply.lfWeight,lfApply.lfItalic,lfApply.lfUnderline,lfApply.lfStrikeOut)

        IF hFont& THEN
            DeleteObject ghTabFont
            ghTabFont = hFont&
            SendMessage ghWndTab, %WM_SETFONT,ghTabFont,0

            'resize all the FORMS/CLIENTS
            CALL SizeClientOnTabs()

            'Draw our Handles at the new locations...
            CALL DrawTabGripHandles(ghMainClient,ghWndTab,ghTabGrip())
        END IF
    END IF

      Jules, Thanks for the example which I regret I am too stupid to use. I see but am still "all at sea".

      This code shows the problem, and the WM_SETFONTs show my attempt to solve it:

      Code:
      #COMPILE EXE
#DIM ALL
#INCLUDE "WIN32API.INC"
#INCLUDE "COMMCTRL.INC"
%IDC_SYSTAB                    = 1010

      IF INSTR(LCASE$(attr), "i") THEN italic = 1
      IF INSTR(LCASE$(attr), "u") THEN uLine = 1
   END IF
   hDC = GetDC(%HWND_DESKTOP)
   CyPixels  = GetDeviceCaps(hDC, %LOGPIXELSY)

        Chris,

        Tested your demo code, and the font works fine on my WinXP Pro box. I don't have any suggestions at this time as to what it might be on your system.

        Regards,
        Jules

        Later...
        Ok, I see, after careful examination of your code, you are trying to set two different fonts on the same control, one for each tab. That's the nature of your problem. To answer your original question, yes you will need to ownerdraw your tabs if you want to have different fonts for each tab. As they say on American Idol, "Sorry!"

          Jules,

          Thanks for looking!

          Today I'm looking for solutions, not challenges, so I shall leave it there.
