Hi, 

Documentation of QStackedWidget::removeWidget() has slightly confusing note:

   Note: The ownership of widget remains the same.

But implementation of QStackedWidget simply delegates removing to the
internal QStackedLayout:

 

void QStackedWidget::removeWidget(QWidget *widget)

{

    d_func()->layout->removeWidget(widget);

}

 

And description of the QLayout::removeWidget() says:

   Note: The ownership of widget remains the same as when it was added.

Therefore you should take ownership of the removed widget to yourself and
delete it manually. For example:

 

// QWidget *widget

stackedWidget->removeWidget(widget);

delete widget;

 

P.S. Documentation of Qt 4.6

Hi, i am using Qstackedwidget to switch between the views, i will be able to
traverse between the views, i am facing problem in some scenario, where i do
not require the widgets, i want to remove them completely.. stackedwidget
provides the functionality to removewidgets, still the ownership of the
widget will be there, i mean widget will be hidden.

i dont want this to be happen, when i call remove widget the widget should
be deleted. how to handle this?

Thanks
