Try this.

Code:

#ifdef Q_INIT_RESOURCE
#undef Q_INIT_RESOURCE
#endif

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. ;-)

An STL Template Experiment

Posted 12-18-2012 at 05:05 PM by rainbowsally

Today's features:

Getting an address of an iterator from stl.
Creating a foreach() macro.
A couple of ways to work around unwanted C++ compiler warnings.

STL is a freaking nighmare to trace in a debugger so it's not too easy to tell what goes on in them but one thing became quite clear and that is that iterators are generic pointer types internally, which makes sense since STL needs to deal with so many different types.

Here's a little test to play with to show how...

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.

[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.

But here it is in it's second incarnation cleaned up a bit though it needs a bit more simplification due to the number of elements that are involved and where they need to go. But this is cool.

Today's Features

Using a custom widget in Designer without making the plugin.
