Qt video tutorials on YouTube
-
Well, I've just watched all the videos I was interested in, and I found them quite good. Thanks for them, and with all the feedbacks and the new ones you will hopefully make, we will get a very good starting point if someone want to learn Qt or just too lazy to read.
Oh, one suggestion, if it possible, try to make bigger the captured area, and see what we get.

A note about video 48.
At the end you say that QThread is not meant to be used with signals and slots. That's not true, a QThread can use signals and slots without any problem.
The problem is thread affinity. Although the documentation is correct and you can in general circumstances subclass QThread and implement the run() function, this will not work easily with signals and slots across threads.
If you define signals and slots inside the QThread subclass, they are called from the main thread context, not the new thread you created.
Maybe it is better to understand that QThread is NOT a new thread in itself. QThread is just a manager for one new thread. The QThread object itself lives in the thread it is created in (the main thread for example).

Is there any facility available for searching with common name we can find all qt related videos in youtube.
For example If I search TED videos, then I can find all videos under TED, with just TED search.
Like wise If I search qtbynokia I suppose should find all videos related to Qt.
Thanks,
Rahul

Lol, man, I've been following your videos and they helped me more or less to understand what a great framework Qt is and got me involved in all I did so far. I even visited your site several times, to look for updates there, as I found it easier at some point. But man! Stop speaking about your "gaming keyboard", lol. Other then that - great work!!!!!

Rootshell thanks a lot for the good videos :) I'm a complete newbie in the programming with GUI (I have only programmed online systems with PHP) and your videos helped me understand a lot of things :)

Wow these videos are excellent! Thanks for taking the time to make them.

I have watched quite a few of these videos and just would like to say thank you for all your efforts in making them. Keep up the great work.
