QFontDialog customization
Message 1 in thread
Are there any functions exposed inside qfontdialog such that we can
customize the dialog ? Say if I don't want do have the 'effect' frame
displayed in the dialog are there any functions exposed to hide the
frame ?

Should be possible using QObject::findChild (and then calling hide on that)
http://doc.trolltech.com/4.3/qobject.html#findChild
(unless you're using the static QFontDialog functions)
Cheers,
Peter

Let me bother with a newbie question.
I wrote a little program in C++ with Qt4. Although usually the program
runs without a problem, it aborts immediately after its invoked when
it's built with -g option and dumps a long message which starts like this:
*** glibc detected *** ./hogehoge: free(): invalid pointer: 0x08052ff4 ***
======= Backtrace: =========
/lib/libc.so.6[0xb707d4b6]
(continues......)
I added -g option by adding CONFIG += debug line to hogehoge.pro.
i'm using openSUSE10.3. I first used Qt4.3.1 provided by YaST and then I
downloaded and installed 4.3.4 to see if it makes a difference, which
produced the same result.
I'd be happy if anybody point out what i'm missing.

I kinda solved this abort problem myself.
The cause was that, in the initialization stage, the program tried to
'delete' an uninitialized pointer. Somehow it didn't do any harm when
the program is built without -g option.
So it was more like my coding problem magnified by the idiosyncracy of
the compiler.
Besides I see some other ununderstandable behaviors of gdb/eclipse-CDT
but I'll try to isolate/summarize the problem and come back later with a
proper 'Subject'.
Thanks
