|Section 1: Overview of Qt|
This course spans for 6 weeks so basic idea is to complete two modules every week .
For Week 1 , we will be covering
So lets get started with the first module
he Qt SDK installer can be downloaded from here.(choose appropriate installer for your OS) This video is a step by step tutorial to help you set up the Qt development environment and to try and run your first Qt application
Now your development environment should be up and running , now you are all set to start by writing your first application in Qt.
This video is a short tutorial to write a simple Qt program and then try to walk through the code to understand as to what actually goes in the background.It also covers some information about the qmake utility tool.
My first Qt application
In this we will start with very basics of layouts we will use a horizontal layout and a vertical layout and will pack the UI widgets inside these layouts. We will then try out the Qt signals and slots feature.
At the end of this module you would have setup your development environment and would have written your first Qt application. You would have also understood the basic concepts of layouts and would have some idea about Qt's signal and slots feature.
If you are interested i would recommend that you follow the Qt Blog , as it's one place where you will find all Qt development posts from Qt Experts.
|Section 2: Object Models in Qt|
In this video we will try to look into Qt Basic Types and how Qt handles strings.
In this module we have learnt the internals of Qt Object model , how to create custom Qt signals and slots and how to have our custom type to integrate with Qt Object model such that it can be used as a parameter in signals and slots. We have looked into the moc tool and how Qt supports these features.
If you have any questions, please ask via the the forum.

|Section 11: Mobile development using Qt|
In order to start development applications for Android , you first need to install the Android SDK along with some other packages. To begin with
These instructions are also available at Qt for Android - Getting Started
Once you have installed the Android SDK , you need to updated the SDK to install the API and tools packages.
In linux OS , you can launch the eclipse IDE that comes with the SDK and go to Window->Android SDK Manager
It should launch the UI and you should be able to install the required API and tools packages. Basically you need to choose
Android SDK Build Tools
Android 4.4.2 (API 19) (latest ) or other available options
Extras - You can choose your packages here
* If not with Eclipse , you can use the command line tool e.g in Ubuntu : ./android update sdk (android - can be found inside
After this the SDK manager install your packages and you should be ready to start development for Android ,
some more instructions you can find in the video below, these are to set the android SDK paths in QtCreator.
To install Qt libraries required by your Qt application you can either bundle the same with your apk or you can use Ministro (you can read about it here)
Please follow these instructions of How to install Ministro , on your device .
Qt and QML technologies are used by Jolla . If you want to work with Jolla , you can download the Jolla SDK and follow the instructions here to get started. The installations will be very much similar to QT SDK install , so it should go fine . If any questions please post to forum.
