How to delete a widget from a stacked widget in Qt

Question

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.. QStackedWidget provides the functionality to remove widgets, 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?

Answer 1

If you add a real object to the stack, it's destructor should be called when removed. If you add a pointer to the stack, then on removal call delete on the pointer.

Note that Qt Objects do reference counting.

Answer 2

Have you tried simply deleting the object after removing it? i.e.

stackWidget->removeWidget(myWidget);
delete myWidget;

Answer 3

Many Qt objects will get automatically removed when deleted. (At least, in the QtGraphics API things work that way) I suspect that simply deleting the object will also remove it, since Qt Objects do emit a signal that they have been deleted.
