Introduction to Qt Quick and User Interaction In QML Video

Hi all,

I have found few interesting video tutorials about Qt Quick and QML. Today I will present you two of them. First video is titled "Introduction to Qt Quick (part 1/4)"
I consider it useful if you want to learn Qt Quick. Video is from Qt Developer days 2010. O.K. so it is not the new video, that is true, but if you are new to Qt Quick this will help you to understand how things work. If the documentation is boring to you this video tutorial is just for you. It has few examples so you can understand what Adam is talking about. I think it is great for beginners like myself.

Second video is titled "User Interaction In QML - User Input and States (part 2/4)"
In this video you will learn:
- to receive mouse and keyboard user inputs from Qt Quick
- signal handlers and property bindings (awareness of user's actions)
- basic understanding of states and transitions

UPDATE: I have found newer versions of this video from October 17th 2011. These two video files are replaced by 3 shorter and newer ones. You can find my newer post here:

Obviously there ate two more videos from where these two came. I still haven't watched them so I will not mention them here. I have also created index of topics covered in videos with time marker. I hope this will make it easier for you to navigate through video after you watched it already.

So here is the first video:

I didn't made these videos. The video is presented by Till Adam and Stephen Kelly. It is done by KDAB and NOKIA.
I got the video from this web address:
http://qt.nokia.com/learning/online/training/training-day-at-developer-days-2010/qt-quick
Unfortunately there were no additional explanations so I decided to write the time table for the video. I just created the "Topics covered in video table". I think it will be useful to you if you wan to get back to a topic inside the video.
