[Qtce-preview-feedback] Qt and Windows CE 5.0 TrueType Problem

[George H. Locktish]

Unfortunately, I don't have the truetype.cpp file.

I do have the OS configured with TrueType font support.  Currently, I
have the Tahoma font installed.  Are there certain fonts that are
required to be installed on the system?

The DEBUGCHK message prevents the application from running entirely.

The stack trace from Platform Builder is:
GWES!Gdi::ExtTextOutW_I(HDC__ * 0x003602e4, int 16, int 12, unsigned int
16, const tagRECT * 0x00000000, const unsigned short * 0x18917ad0,
unsigned int 1, const int * 0x00000000)  line 1590 + 60 bytes

NK!SC_ExtTextOutW(HDC__ * 0x00000000, int 412187344, int 1, unsigned int
0, const tagRECT * 0x838f5b6c, const unsigned short * 0x0a000000,
unsigned int 2205825960, const int * 0x00000000)  line 974 + 76 bytes

COREDLL!ExtTextOutW(HDC__ * 0x003602e4, int 16, int 12, unsigned int 16,
const tagRECT * 0x00000000, const unsigned short * 0x18917ad0, unsigned
int 1, const int * 0x00000000)  line 615 + 72 bytes

181fb47c()


The call stack only contains the symbols from the system DLLs.  I have
built the Qt GUI application in debug mode, but I am not getting debug
symbols.

I can reproduce this issue with a minimum Qt application (one that just
shows a QMessageBox). 

Thanks,
George

Do you by chance have the truetype.cpp so that you could tell us, what 
the actual check is? Beside that, do you have TrueType fonts installed 
on this system or are you using raster fonts? It might be related to the

fact, that Qt tries to load TrueType ones while they do not exist.

Does this DEBUGCHK message prevent you from starting your application in

debug mode at all? If so, is a stack crawl available?
