creating a QWidget in the global space

[wambagilles]

please i need help, for my programm i need to have a static attribute in a class, but that attribute should be a QWidget, i tried it, but the programm will crash becaused i initialised it in the global space, and it had no parent.

i had no issue creating static QString attributes and initialising them in the global space.

please how could i do to the same, but with a QWidget (that needs a parent) ?

I'm intrigued, what problem are you trying to solve with a static QWidget?

[wambagilles]

i need to create a single instance of a qwidget that can be used in all classes of the programm.

I don't see a problem. Just use singleton pattern.

// static method
YourWidget* YourWidget::instance()
{
    static YourWidget* ins = 0;
    if (ins==0)
         ins = new YourWidget(qApp);
    return ins;
}

// static method
YourWidget* YourWidget::instance()
{
    static YourWidget* ins = 0;
    if (ins==0)
         ins = new YourWidget(qApp);
    return ins;
}
