More Tooling Up Stuff

Posted 12-19-2012 at 11:52 AM by rainbowsally
Updated 08-06-2014 at 09:30 AM by rainbowsally (skip rant, typo correction)

About the commandline

Today's features:
  • Why the commandline rocks and GUI apps have rocks in their heads at times.

You can skip this somewhat rambling rant by going down to "CONTINUE" below.

[Note for KDE users: Konqueror has a nice konsole terminal that can be opened with F4. It's much MUCH better than Dolphin, if you're a programmer. See recent blog including 'launch' and shell-exec if you have trouble executing these files when you click on them...

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...

Updated 06-10-2013 at 04:17 PM by rainbowsally (bullet list not showing correctly + typo fix + parag alignment)

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)

Posted 12-15-2012 at 09:57 AM by rainbowsally
Updated 12-15-2012 at 08:29 PM by rainbowsally (linkage to first part + parag alignment fixed)

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'...
