Best way to learn Qt

[vermarajeev]

Then there is no reason to teach them Qt if they don't know any other toolkit and want to switch environments (switch from what?).

No!!!. There is a reason. Here it is...

Ok I agree attendants have to have some knowledge on some toolkit but there can be cases where the attendants are just fresh passed out. They might have done some small project during their colleges. So there is possibility that they have some domain knowledge (might not be MFC). It can be either Visual Basics, Networking, C, C++, Computer Graphics, Java etc.

When I learned Qt I only knew C, C++, Visual Basic etc but not MFC. I think if you have a strong C++ background, then learning Qt is somewhat easier. There is QtAssistance which makes your life much easier. QtAssistance has everything but you need to find the proper function to fit in proper place.

I'm just assuming majority of attendant have knowlwdge on C, C++ and few on MFC. In that case what can be your classic idea????

By the way wysota, can you share some of your experiences learning Qt for the first time. I wil love to hear that.

One more small question.. Assume attendants knows only C, C++ and not other toolkits.( and NOTHING). You have 10 such people and you are asked to teach Qt to those people. How do you do proceed???? Please put down all you ideas.

This is going to be interesting. I'm eagerly waiting.

Well, I would begin by sorting out how much of a C/C++ experience they have. If some of them know only C, then you should start teaching them with C++ ( best of luck ) . I would first access the skill levels and then give lecture according to that. You cannot expect a C guy to know the polymorphisms in C++. So the minimum requirement would be that they should know C++ well. You could give a quick intro to C++.

If you have the copy of C++ Gui programming book. the Appendix B will help you.
It explains about Header files, breaking the program into different headers, Classes, subclassing. operator overloading, virtual mechanism ... If your students have trouble understanding it, then give assignments on that. Once C++ is done

I would start out with the Qt tutorials in the Assistant...
Gradually explain about the Designer. Give a couple of simple assignmenst like a notepad, calcuator, ...

These assignments will help them get a taste of Qt. Once that is done proceed to higher concepts like events, Subclassing widgets , creating a widget from sratch ..., Plugins etc

Java or Visual Basic are fine too. Let everyone program in the language/toolkit of their choice (be it Swing or VB).

But you didn't attend a training for employees (God, what a hard word, I probably misspelled it). In that case the path has to be different.

Hmm.... Maybe this?

#include <QApplication>
#include <QPushButton>
 
int main(int a, char **b){
  QApplication app(a,b);
  QPushButton c;
  c.setText("Hello world!");
  c.show();
  return app.exec();
}

#include <QApplication>
#include <QPushButton>

int main(int a, char **b){
  QApplication app(a,b);
  QPushButton c;
  c.setText("Hello world!");
  c.show();
  return app.exec();
}

To copy to clipboard, switch view to plain text mode 

And seriously prepare some slides explaining basic concepts of Qt (QObject memory management, signals and slots, object introspection) and then expand to add new topics. And make them write some code...

By the way wysota, can you share some of your experiences learning Qt for the first time. I wil love to hear that.

Oh, sure... no tutorials, trial and error, segfaults, segfaults, segfaults (when accessing GUI from worker threads)... and then I learned to use Assistant correctly Then registered at QtForum and started answering questions. That helped very much Oh and about half a year later I wrote my first more serious working application ("working" is the key word here).

I'll tell you in three months

Ha Ha Ha, Interesting!!!! I'm waiting for 3 months to get over.

Can you please tell me some assignments samples to be given.

thanks.
