Is anyone interested in me doing a serious tutorial on how to create a functional application in Qt4 from the ground up? Vote on the poll, if there's enough interest then I'll document my current project as I work on it. Current project that I'm working on is a fairly simple Omegle (omegle.com) chat client. The tutorial would obviously demonstrate UI development, signals, slots, and networking using Qt, code in c++.

Qt4 is a widget based framework from nokia, mostly to do with GUI's but they have other APIs too for networking and stuff like that.

Here's a simple Hello World app:

main.cpp

Code:

#include <QApplication>
#include "include/MainWindow.h"

int main(int argc, char* argv[])
{
    QApplication app(argc, argv);
    MainWindow mainWin;
    mainWin.show();

    return app.exec();
}

include/MainWindow.h:

Code:

#ifndef MAINWINDOW_H
#define MAINWINDOW_H

#include <QMainWindow>
#include <QLabel>


class MainWindow : public QMainWindow
{
    public:
        MainWindow();
    protected:
        void closeEvent(QCloseEvent *event);
    private slots:
    private:
        QLabel *container;
};

#endif // MAINWINDOW_H

src/MainWindow.cpp:

Code:

#include "../include/MainWindow.h"

MainWindow::MainWindow()
{
    container = new QLabel(this);
    container->setText("Hello World!");
    setCentralWidget(container);
}

void MainWindow::closeEvent(QCloseEvent *event)
{

}

thanks for that lovely contribution!

Isn't this C language?

my particular example is written in c++.


Qt does have c and c++ libraries though.

I almost started using Qt4 from ruby native c extension yesterday, but didn't feel like installing a sane build enviroment for windows where I was gonna use the code. I ended up just settling on java swing (jruby). I'm writing a little google voice desktop sms client.

It's just that they all post "Hello Worlds", why not post more advanced samples!

it's an introduction to UI development with Qt, it doesn't just print hello world, it builds a Qt window
