An afterthought:
While poking around in this stuff I found this warning in the linux/if_ether.h header.

Sockets - A Packet Snooper With A QT4 GUI (Req's libLQ-qt/mc2 dload) Part 1

Today's feature is
  • Running a packet snooper in an lqMiniTerm 'run' loop function.

[Note: the lqMiniTerm is evolving a bit and will continue to evolve for a while as we experiment and discover things that come up over and over that are easier to address in the mini terminal than in the main() file's code. Currently term_printf() is a candidate for becoming a miniterm feature. Find out why! :-) ]...

mini-term in qt4

Posted 01-17-2013 at 03:34 AM by rainbowsally

mini-term in qt4.

Today's features:
  • A simple terminal-like application built from a qt4 class that can be used for other stuff too.
  • The present application can run shell commands and has copy/paste (ctrl-c, ctrl-v) capabilitity.
  • Another example of the Windows-like api so that C/C++ code can run in Qt4.
  • Runs the custom code (terminal in this case) inside a QT 'exec' loop... sorta. We call it 'run()'.

QT4 -- Having trouble with qInitResouces_<appname>() ?

Having trouble with qInitResouces_<appname>()?

Try this.
Code:
#ifdef Q_INIT_RESOURCE
#undef Q_INIT_RESOURCE
#endif

#define Q_INIT_RESOURCE(name) extern void qInitResources_##name()
The version of this macro in qglobal.h could never have ever worked.

If you enjoy digging into the low level stuff, I think you'll be amused by the context of this bug. ;-)

"Old Style" Callbacks In QT4 (commandline tester)

Posted 12-12-2012 at 08:25 AM by rainbowsally

What would be involved in creating a generic callback that we could control ourselves, rather than using QTs rather complicated system?

How about a windows style system with a windproc to handle messages?

QT's API is better than windows in that you can see how things are done, especially if you have the C++ sources. It's as visible as you can stand! ;-)

The Windows API is better than QT's only in one respect, and that is that the type safety is somewhat...
