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...

Tooling Up. ui-tool (QT4 ui file utilites)

Posted 12-15-2012 at 10:16 AM by rainbowsally

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.

But the app itself doesn't require the libs. It will 'make' and run without the libs or mc2, if that's all you want in the mc2 dload. I.e., The makefile exists. After that mc2 is no longer needed.

Tooling Up.

This tool is worth the effort...

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

Code:

  ok = find_slots(...);

we need to return 'true' without acting on the return values but not return 'false'...

[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.
Using the "Old
