QT: How to open several windows (QWidgets) at once?

I'm doing web interface testing program which should open two urls in two webkit windows simultaneously.

I already did the code for the test automation.

1) User pushes 'Go' button and webkit (QWidget) window opens

2) TestBot class object performs tests

3) Closes

Now my questio开发者_JS百科n: After clicking on the button 'Go', how do I open two (or three or more) webkit (QWidget) windows, I mean, how do I launch several TestBots simultaneously so they do all the work parallel?

I understood, that I need to look at multithreads, I came up I need to inherit QThread into my TestBot class definition as 'class TestBot : public QThread', but is this right solution and do I do it right? What's to do next?

Can't I just write code as:

QThread process1;
QThread process2;
process1->start();
//some code here
process1->quit();

process2->start();
//some code here
process2->quit();

to make everything work parallel?

I'm a newbie in Winapp world, I came from Web programming. Hope for your help!

In order to show multiple windows at once, just line them up and show them.

void ShowMultiple()
{
    QWidget *win1 = new QWidget();
    QWidget *win2 = new QWidget();
    QWidget *win3 = new QWidget();

    win1->show();
    win2->show();
    win3->show();
}

After this code runs, there should be 3 new (blank) windows shown. However, if you are trying to execute some code that takes a long time along with showing the windows, things might change. In that case, you might want to look at the threads or Qt::Concurrent examples, bearing in mind that you really, really can't mess with the UI in any other thread.

You can try to use the functions into the QtConcurrent namespace for asynchronous tasks, specially the run one.
