Tooling Up: Clickable Script Programs

Posted 12-13-2012 at 02:10 PM by rainbowsally
Updated 12-23-2012 at 04:15 PM by rainbowsally

Note: shell-exec and lq-launch (the lq version) are now included in the mc2 libLQ d/load. They are in the examples/goodies folders and can be copied directly into your ~/bin folder and should be usable immediately with no changes to your paths required.
---------------------------------------

Today's Features
  • Clickable sequential backup utility. You'll need to create a program to copy it to the directory you want to use it in. That's pretty easy, but well.. maybe not.

Generic QT Signal/Slot --or-- Using Dummy Custom Widget in Designer -- No Plugin Req'd

Posted 12-13-2012 at 01:52 PM by rainbowsally

[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

A Stand Alone executable QT MsgBox with Stays On Top attribute

Posted 12-13-2012 at 07:59 AM by rainbowsally

A Stand Alone executable QT MsgBox with Stays On Top attribute.

Today's Features:
  • A non-modal qt based dialog/message box that STAYS ON TOP of the window stack.
  • How to center a window on the screen.
  • 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.

Data recovery from CD-ROM with Debian 6 Squeeze - ddrescue

Posted 12-12-2012 at 10:00 AM by error_401
Updated 01-14-2013 at 07:27 AM by error_401

I happen to have a huge amount of pictures but they are stored on CD-ROM's which over time start to loose data. Some after 3 years some are still readable after 12 years.

Nevertheless I want to recover as much data as possible and store it on my NAS. Now the task is not so straightforward as expected. Again the sheer mass of information sometimes hides the most obvious, or what is obvious to me was not to the developers or editors of tutorials.

The tasks are

"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...
