Could you please let me know how can we configure Qt 2.5.2 for the beta
snapshots
http://releases.qt-project.org/qt5.0/beta-snapshots/latest/
Your help in this is greatly appreciated.
Thanks and Regards,

Hi Everybody,
I come from a Delphi background. A while ago the FastMM memory allocator
was adopted by the compiler team because it gave very good results for small
allocations. It's not quite SLAB - it only looks at the size, not the type
of object, since all Delphi objects are initialised t

You put up an alert telling the user that the operation can't be completed due
to insufficient memory, and then field the tech support call that resu

In the past months we've seen the Symbian code be removed from Qt5 due

iOS and Android support, i

Interesting thread. I like the bit about allocating everything you could
possibly need at application startup. I tend to do the same thing when
dealing with multiple buffers (never crossed my mind to do it with
widgets), but always wonder if I'm prematurely eja optimizing. Onto my

It's called win32-msvc2008.
"win32" doesn't stand for the number of bits, it stands for the Win32 API.
That is not changed

Hi Scott,
For Windows you don't need separate mkspecs for 32 and 64 bit. When building
Qt from source your choice between a 32 and a 64 bit build is
determined by the type of Visual Studio command prompt you open. For VS2010
it works exactly the same.

Could you please let me know how can I configure Qt creator 2.5.2 for Qt5
version from git.
so that I can run the Qt5 application using Qtcreator.

If that's the case, why doesn't Qt support 64 bit natively for VS 2008?

Well let me explain, on this particular product, it is a 32-bit CPU and
application on smart-phone similar hardware (256ram/512flash). The existing
application is very table-based (fixed allocation, as rule 3 in the JPL PDF
goes), minus a few file handling routines. The files are a few MB in si

In Qt, very little. We're not going to change the programming paradigm.
In C++, a bit more. You can write code with special allocators.
You can also change the implementation of malloc(),

The classical answer from the realtime world is: Don't deallocate

In our application, we instantiate at image startup time every

Initially I thought there might be some kind of QObject d-ptr magic where the
large allocations can be in the private class and re-allocate and copy the
private class, without affecting the pointers that the application uses. Then

In comparing technologies (Qt vs .NET) one of the biggest architectural
differences is the garbage collection model.
Qt uses the standard C++ new/free, where .NET uses a garbage collector.
Interestingly the GC not only manages overall usage, but can move objects
around in memory. This is the

Hi all,
Is there a safe way to get char * from QByteArray which is not destroyed when
original QByteArray is destroyed?
I'm thinking about something like
QByteArray ba = ...;
char *data = ba.data();
ba.data() = '\0';
