Hi,
I have configured Qt5 beta using TDM-Mingw32, perl and python (all latest
versions) and then tried to build using following commands
1. configure -developer-build -opensource -nomake examples -nomake tests
( to configure)
2. perl build -j 2 (to build)
But build has failed a
Hello.
Is it safe to write in to the QTCPSocket from the different threads if

I'm certainly no expert
Hi Jason,
If there are 5 public objects whose d-pointers reference the same private
object address, how are you going to update them when you relocate the
private object?
I don't think .Net stores addresses, just handles, so the relocate only
needs to update the handle info. That's why
I'll take that as a compliment. I fully expected someone to raise the issues
you did. And I will counter them with the following comments.
Yes, Qt would be less predictable, but more predictable than .NET's allocator.
If you want GC-like features, it'll come at a GC-like price.
Next on when to d
I doubt that implementing moveable private objects/pointers would be
[really] useful.
Firstly, Qt can't control the location of the memory block allocated
by new/malloc, so the assumption that some [random] reallocations will
improve the contiguity of allocated memory looks quite naive.
Secondly,
It depends on functionality you need and type of your dialog (modal/modeless)
In any case I do not think appropriate time is when dialog is closed.
Check QDialog documentation for example at:
http://doc.qt.nokia.com/4.7-snapshot/qdialog.html
In general for modal dialog you might want to update da

Hi all,
What are the best practices to return from a common dialog window?
At the moment I have already solved with a Slot connected to the closure of the
dialog,
that invokes methods to retreive data. But what are the best practices?
What are the pros and cons of every solution?
TIA,

Binding to C/C++ should be simple and the debugger should be embeddable.
In times of Qt4 this would be QtScript and scripttools/debugging but this is
all "done".

It looks like the current version of the ActivePerl (5.14.2 Build 1402
(64-bit)) has an outdated version of the GetOpt::Long module (2.35) which does
not have GetOptionsFromArray yet. The required version is 2.38. I just
