Re: Creating threads in Qt/X11
Message 1 in thread
you need to subclass your designer class. if you created a main window in designer, you would have
something like
class MyMainWindow : public QMainWindow, public Ui:MainWindow
{
// ...
};
I would suggest looking into the book "C++ GUI Programming with Qt 4" [1], everything described
nicely in there..

WRONG!
1.) You must NEVER put GUI-related stuff into a seperate thread!
2.) He's using Qt3 - that's why "uic" is creating all class-code he needs.
Just subclass from QThread with an editor of your choice, write your
thread code and create that thread at a reasonable position in your code.
Don't forget to add your new source/header files to the .pro file.

Message 4 in thread
Hello,
I am new to Qt/X11. I am now working on the Qt Designer. I want to create a new thread in Qt.
My question is:
The Designer has embedded all the event handling code in the ui.h file. I know that to create a thread in Qt, we subclass from QThread class. But where can I create a subclass of QThread? Can I create this in ui.h or create another .cpp file and include the .cpp file in ui.h?
Any help/suggestions would be very helpful. Also how can I add new member variables to a form in Designer. Adding new functions to form is very simple.
Thank you.
Pankaj.

The Designer is only for GUI work. For the real code you need to use an
actual editor. It is called "programming", not "clicking"... ;-)

Thanks, Konrad. I do understand that to create threads in Qt, we need to
write the code. I am writing an application where I have already developed
the GUI using the Designer.
My question is: can I write the code in the actual editor and then include
the same in the ui.h code, using #include directive? As I need to integrate
both these code snippets.
Thank you.
Pankaj.
