will Qt delete all dynamic data?

[Lykurg]

where do you want to show it?
Inside your main window: use layouts.
outside your main widnow: use QDialog as a base class for example. or set the modal widget attribute.

hmm.. I have one problem.
My app has one QMainWindow, and several other QWidget that can be show on QMainWindow(one at the time, and it is not QTabWidget!!).

There are several situations:

class Widget : public QWidget
{
     Widget(QWidget *parent) : QWidget(parent) {};
}
//In this situation, on my QMainWindow are showing several widget at the time
 
 
class Widget : public QDialog
{
     Widget(QWidget *parent) : QDialog(parent) {};
}
//In this situation, widget show as a dialog, on other window (not in QMainWindow)
 
class Widget : public QWidget
{
     Widget() {};
}
//In this situation all works fine, only this widget are showing on QMainWindow at the time. But it brings memory leaks, 
// because this widget has no parent, and i need to delete it by it self..
 
//In my QMainWindow I do this:
setCurrentWidget(widget)

class Widget : public QWidget
{
     Widget(QWidget *parent) : QWidget(parent) {};
}
//In this situation, on my QMainWindow are showing several widget at the time


class Widget : public QDialog
{
     Widget(QWidget *parent) : QDialog(parent) {};
}
//In this situation, widget show as a dialog, on other window (not in QMainWindow)

class Widget : public QWidget
{
     Widget() {};
}
//In this situation all works fine, only this widget are showing on QMainWindow at the time. But it brings memory leaks, 
// because this widget has no parent, and i need to delete it by it self..

//In my QMainWindow I do this:
setCurrentWidget(widget)
