UPDATE: (2013-06-10) There's a stand-alone version of the uitool here.
http://www.linuxquestions.org/questi...3-06-10-35568/

It's part of the next libLQ-qt/mc2 project but that lib is not ready to fly yet.

--------
Note: This is now part of the libLQ-qt download, but it's been renamed lq-uitool. It builds in the tools folder and should install automatically if all goes well.

ui-tools implementation (ui-tools.cpp)

The following changes are in the code below, but are listed in case you already have the file and want to fix it yourself (and see the context of the problem).

Changelog Dec 15 2012 (second prob)
"Unknown error" msg issued when it's not an error.

Here's the fix. Whenever we call

[This is FUN!! It works. What a freaking trip. :-)]

The previous entry on using Old Style callbacks wasn't much of a hit. Ooooooohhhh... it's a hit alright.

Using the short optargs to parse the options.

The msgbox utility in the 'extras' folders of the mc2 d/load (see link below) uses xmessage for the display widget. That makes it independent of QT so it can run on any computer that has the X windowing system.

"Old Style" Callbacks In QT4 (commandline tester)

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...
