How to show a window widget...

... from a QMainWindow ? (but not in main.cpp)

in CLinkGUI.cpp :

Code:

---

void CLinkGUI::tests()
{
    ui_sofImpl test;
    test.show();
}

---

When I do this :
in main.cpp :

Code:

---

int main(int argc, char **argv)
{
    QApplication app(argc, argv);
    ui_murefImpl window;
    window.show();
 
    ui_sofImpl test;
    test.show();
 
    return app.exec();
}

---

it works but that is not what I want...

my not modified main.cpp :

Code:

---

int main(int argc, char **argv)
{
    QApplication app(argc, argv);
    ui_murefImpl window;
    window.show();
 
    return app.exec();
}

The first code (in CLinkGUI.cpp) shows me my widget but close it imediately...

Thanks :D !

Please delete this topic -> I found the solution : Read the FAQ !

Because the widget is created in the function tests() and destroyed once out of the function.

It should rather be

Code:

---

void CLinkGUI::tests()
{
     ui_sofImpl *test = new ui_sofImpl;
     test->show();
}

Make sure you set the widget attribute Qt::WA_DeleteOnClose so that the widget is deleted automatically when it is closed.

I just added static before declaration of the variable :

Code:

---

static ui_sofImpl test;
