Call a Qwidget outside of a non QT app

Massi

Hello,

I have vs2012 dll project and I managed to integrate Qt5.4.1 library in it. I want to use QWidget to open a window or do wherever I want with it like in QtCreator but when I try to call it,

void myfunction::callQt()
{
        QWidget* mywidget = new QWidget;
        .....
}

I get a pop-up window saying:

must construct a qapplication before a qwidget

I know that I don't have a QApplication and I don't know how to create it in my dll? do you have any example?

Thanks in advance!

Hi,

I haven't used it but the QtWinMigrate module might offer hints about how to do it.

Otherwise, there this stackoverflow post that could be interesting.

Hope it helps
