[Qt-interest] show a widget without a main window

[knowledge seeker]

Sorry for the wrong link.

The correct link is
http://doc.trolltech.com/4.4/tutorials-tutorial-t5.html

In constructor of MyWidget() please see that
 QPushButton *quit = new QPushButton(tr("Quit"));

Hence there is no this passed as parameter, while creating the quit-object.

Now what do you suggest ?

Does layout->addWidget(quit);  take care of the before-mentioned
parent-child delete-mechanism ??

If yes, then does setLayout() method also somehow helps deleting the
object QVBoxLayout *layout ??
