Answering my own question... Yes QNAM handles receiving compressed
responses no problem.
Would still be nice to know how to enable it for sending compressed
requests?

Hi Everybody,
My application talks to an Apache server to send and receive xml data.
Most of the request xmls are small. The response xmls can vary up to 10Mb.
It has been suggested to use
http://httpd.apache.org/docs/2.2/mod/mod_deflate.html to compress the
responses. Will QNAM handle this? N

Adding qt version should work without any problems if your build is proper.
While adding a new version, you just have to show the location of qmake.exe
where ever it is installed.

Is there a way to store a 64-bit internal ID in QModelIndex? The
function QModelIndex::internalId() returns a 64-bit number but there's
no way to put one in. The constructor takes only a 32-bit integer.
Thanks.

Given the network-centric world we live in, I usually think about networks, not
disks, because as you point out, there are a variety of faster-than-rotational
media - be RAM FS, flash FS or some other kind of mixed (SSD). Still the CPU is
orders of magnitude faster than anything but a ramdisk.

In the "modern world", be a little cautious when you decide what activities can

I need to show some standard (on the Mac at least) icons in my app, like
pedlock or stop/error signs. On the Mac, it's done via a set of standard
icon "signatures" like:
enum {
kGenericFolderIcon= 'fldr',
kDropFolderIcon = 'dbox',
kMountedFolderIcon
Not true for really large XML. With the all-in-one approach, you have to have
the entire document completed. This will create a long pause, and increase
latency, and increase memory usage. It can be very easily justified that many
to Utf* calls are justified because of latency in the I/O system
By returning out of memory, unrolling the stack, then at the top level
displaying the error.

Or, just restructure your program to be multi-process so each process has 3gb

Which is a great approach if you have virtual memory. But I don't.

I only use VS2008, and I have routinely compiled 4.6, 4.7 and 4.8 lines of Qt
